The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente As normal milk tastes sour when it contains about 0.3 per cent lactic acid, a milk that tests as much or more than this without tasting sour has been probably treated with this antiseptic agent. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying Failing this, milk will undergo, not lactic fermentation, but putrefaction, and thereby develop highly dangerous qualities. The Healthy Life, Vol. V, Nos. 24-28 The Independent Health Magazine It is formed in the lactic acid fermentation of sugar, and by the action of nascent hydrogen on glucose and cellulose, or on invert sugar. Nitro-Explosives: A Practical Treatise The amount of lactic acid formed from the sugar fermented is dependent upon the kind of bacteria present. Outlines of dairy bacteriology A concise manual for the use of students in dairying Simultaneously a true lactic acid fermentation proceeds and eventually gives place to a subsequent 97 secondary production of butyric acid. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente The result of this enormous bacterial multiplication is that acid is produced in cream, lactic being the principal acid so formed. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying When a person takes soured milk its lactic acid acts as a powerful germ destroyer and in a certain concentration it actually kills the lactic germs as well. The Healthy Life, Vol. V, Nos. 24-28 The Independent Health Magazine This seems due to its being little liable to putrefaction, the bacterial fermentation to which it is liable producing lactic acid—the souring of milk. The Chemistry of Food and Nutrition None of these attempts have stood the test of practical use in creameries, and it has been demonstrated that the finest type of butter can be made by the use of lactic bacteria alone. Outlines of dairy bacteriology A concise manual for the use of students in dairying The presence of the two latter organisms is favourable to the production of good koumiss, as, by inducing a preliminary lactic fermentation, they tend to inhibit the growth of undesirable extraneous bacteria, etc. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente The continued formation of lactic acid kills many of the bacteria and thus weakens the fermentative action. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying I have often found an obstinate cough yield to a diet which contains lactic acid buttermilk, combined with the use of the new oxygen baths. The Healthy Life, Vol. V, Nos. 24-28 The Independent Health Magazine His lips quivered as if in uncertainty as to whether he was to be left out of this lactic deal, and his eyes grew reproachful. Rose of Old Harpeth It has been found that this condition is not necessarily due to contamination, as was considered true in the past, but rather to some change in the lactic bacteria themselves. Outlines of dairy bacteriology A concise manual for the use of students in dairying It has long been known that milk allowed to become sour will keep for a considerably longer period in hot weather than if lactic bacteria had not grown. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente The lactic acid group of organisms disappear quite rapidly; the spore-bearing species remaining for a somewhat longer time. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying The lactic acid buttermilk can be obtained from any good dairy and should be taken in the morning fasting and at bedtime. The Healthy Life, Vol. V, Nos. 24-28 The Independent Health Magazine In Portugal, where there isn't so much separating of the sheep from the goats, it takes several weeks for Alemtejos to ripen, depending on the lactic content and difference in sizes. The Complete Book of Cheese Every process by which the desirable lactic bacteria are increased in proportion to other kinds has a marked effect in enhancing the keeping quality of the butter. Outlines of dairy bacteriology A concise manual for the use of students in dairying Needless to say, this product must possess some of the characteristic by-flavour of the yeast employed, and is less suitable than koumiss prepared by the aid of a lactic yeast. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente The chemical reaction of cheese is normally acid to phenolphthalein, although there is generally no free acid, as shown by Congo red, the lactic acid being converted into salts as fast as formed. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying Water slightly acidulated with sulphuric, nitric, or muriatic acid will probably be the best, but it is hoped that phosphoric, acetic, and lactic acids will prove equally good. Scientific American Supplement, No. 483, April 4, 1885 It is made by mixing one pound of lactic acid with one pound of glycerine and eight pounds of water. Burroughs' Encyclopaedia of Astounding Facts and Useful Information, 1889 To secure rapid curdling in the vat, the milk is warmed to 85� to 90� F., a temperature that is most favorable for the growth of the lactic bacteria. Outlines of dairy bacteriology A concise manual for the use of students in dairying By the formation of large quantities of lactic acid, a state of asepsis is ensured, which is particularly valuable in cases of operations on the abdomen and intestines. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente These gas-producing organisms are to be found, sparingly at least, in almost all milks, but are normally held in check by the ordinary lactic species. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying This method of preservation is especially applicable to those vegetables which contain so little sugar that sufficient lactic acid cannot be formed by bacterial action to insure their preservation. Every Step in Canning This organism has the power of transforming milk sugar and other saccharoses into lactic acid, with evolution of carbonic acid gas. Scientific American Supplement, No. 530, February 27, 1886 The lactic acid bacteria have increased materially in numbers. Outlines of dairy bacteriology A concise manual for the use of students in dairying The presence of the latter is very undesirable, as it rapidly combusts the lactic acid, digests the casein, and imparts a strong unpleasant cheesy flavour to the beverage. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente It has been claimed that the use of a pure lactic ferment as a starter enables one to overcome this defect. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying The vital factor in preserving the material by this method is the lactic acid which develops in fermentation. Every Step in Canning In these are two micrococci, both of which cause the production of lactic acid, but which manifest differences in their development under cultivation. Scientific American Supplement, No. 530, February 27, 1886 The lactic bacteria are therefore an essential factor in inaugurating the ripening changes in all types of rennet cheese. Outlines of dairy bacteriology A concise manual for the use of students in dairying This preservative action of lactic acid also comes into play in the manufacture of sauerkraut and in the preservation of meat by immersion in sour milk. The Bacillus of Long Life a manual of the preparation and souring of milk for dietary purposes, together with and historical account of the use of fermente It develops lactic acid rapidly, coagulating the milk and producing an intensely bitter taste in the course of one to three days. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying In the well-known method of vinegar pickling the acetic acid of the vinegar acts as a preservative like the lactic acid produced by fermentation. Every Step in Canning Dr. F. Hueppe, who has paid great attention to this subject, describes five distinct organisms which he finds to be invariable accompaniments of lactic fermentation. Scientific American Supplement, No. 530, February 27, 1886 The result of the fermentation in this case is the production of lactic acid, which makes the milk sour. Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables According to Mitscherlich, the combination with the proteine or albuminous substance is not a permanent one, but suffers a decomposition by various acids, as dilute acetic and lactic acid. Scientific American Supplement, No. 385, May 19, 1883 Most of them are the lactic acid bacteria, which change the milk sugar into acid. Maintaining Health Formerly Health and Efficiency When you have made this test and discovered that the bubbling has ceased, then it is time to protect the food from all organisms which destroy lactic acid. Every Step in Canning Sourness -- N. sourness &c. adj.; acid, acidity, low pH; acetous fermentation, lactic fermentation. vinegar, verjuice†, crab, alum; acetic acid, lactic acid. Roget's Thesaurus of English Words and Phrases When it is allowed to stand for some time, these bacteria act upon the sugar, or lactose, contained in the milk and change it into lactic acid. Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables Thus the bacteria lactis act upon the milk sugar present in milk, and convert it into lactic acid, thus bringing about the souring of milk. A Practical Physiology Even if the milk is kept cold, bacterial growth will soon take place, but it will perhaps not be lactic acid bacteria. Maintaining Health Formerly Health and Efficiency Its acidity is probably due to muriatic or lactic acid—the acid of sour milk. Hygienic Physiology : with Special Reference to the Use of Alcoholic Drinks and Narcotics Hence lactic acid acts in a very peculiar manner, causing inflection at an extraordinarily slow rate, and being highly poisonous. Insectivorous Plants This mass continues to grow sour and tough until all the milk sugar is converted into lactic acid, so that the longer the milk stands, the more acid it becomes. Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables This is due to the fact that lactose undergoes the lactic acid fermentation. A Practical Physiology These ferments have as their basis the lactic acid bacteria, and if the manufacturers wish to call their germs by other names, such as Bacillus Bulgaricus, no harm is done.

The Harvard Classics Volume 38 Scientific Papers (Physiology, Medicine, Surgery, Geology) Any sample of sour milk may therefore always be depended upon to contain plenty of lactic organisms. The Story of Germ Life Whey is composed of water, minerals, and milk sugar or lactic acid, and is the least valuable part of the milk. Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables The lactose is converted into lactic acid by means of a special ferment. A Practical Physiology Do not use metal dishes, for the lactic acid acts upon various metals. Maintaining Health Formerly Health and Efficiency The cells belonging to the grains of barley, or their albuminous contents, never do produce cells of alcoholic ferment, or of lactic ferment, or butyric vibrios. The Harvard Classics Volume 38 Scientific Papers (Physiology, Medicine, Surgery, Geology) To start the fermentation the mixture is inoculated with a mass of sour milk or decaying cheese, or both, such a mixture always containing lactic organisms. The Story of Germ Life Here the lactic acid bacteria produce the acid from milk sugar, but the process stops when about seven-tenths of one per cent. of lactic acid has developed. The Story of the Soil; from the Basis of Absolute Science and Real Life, Sweet, chopped, immature field corn becomes sour silage in the silo, lactic, acetic, carbonic and other acids being formed. The Farm That Won't Wear Out It does not form big, tough curds in the stomach, it is easy to digest, and the lactic acid helps to keep the alimentary tract sweet. Maintaining Health Formerly Health and Efficiency Nor, again, does the mere presence of lactic acid necessarily imply the presence of lactic ferment. The Harvard Classics Volume 38 Scientific Papers (Physiology, Medicine, Surgery, Geology) Here also there is a possibility of an improvement in the process by the use of pure cultures of lactic organisms. The Story of Germ Life As Signor Bragato observes, if they are too warm the fermentation will start with too high a temperature in the must, and very likely the result will be the formation of lactic and acetic germs. The Art of Living in Australia ; together with three hundred Australian cookery recipes and accessory kitchen information by Mrs. H. Wicken Likewise sweet milk becomes sour, with the formation of lactic acid. The Farm That Won't Wear Out The lactic acid seems to be quite beneficial. Maintaining Health Formerly Health and Efficiency His second, in which that influence is noticed, was published in January, 1858, that is, subsequently to our work on lactic fermentation, which appeared in November, 1857. The Harvard Classics Volume 38 Scientific Papers (Physiology, Medicine, Surgery, Geology) At the present time the only method we have for the manufacture of lactic acid is dependent upon bacteria. The Story of Germ Life The resulting wine, a curious mixture of alcohol, sugar, lactic acid, and water, is most unpalatable, sour, uninviting, and unwholesome. besides ruining the name of Australian wine when sold as such. The Art of Living in Australia ; together with three hundred Australian cookery recipes and accessory kitchen information by Mrs. H. Wicken "Milk, thank ma'am, please," demanded Martin Luther quickly, having no intention of being left out of any lactic deal. The Road to Providence Metchnikoff thought for a while that he had discovered how to ward off decay and old age by means of the lactic acid bacteria in milk. Maintaining Health Formerly Health and Efficiency Or various forms of lactic acid fermented milk may be successful. Disturbances of the Heart The lactic-acid organisms affect the milk sugar and produce lactic acid; others act upon the fat, producing slight changes therein; while others act upon the casein and the albumens of the milk. The Story of Germ Life Even a weak acid, as the lactic acid of sour milk, sets this free, and thus causes the dough to rise. An Introduction to Chemical Science The lactic acid in sour milk is a direct antidote to the poison of erysipelas. The Royal Road to Health If this step in digestion is performed by the acid in the fruit no more harm is done than when it is performed by the lactic acid bacteria. Maintaining Health Formerly Health and Efficiency Intestinal antisepsis may be attained more or less successfully by the administration of yeast or of lactic acid ferments together with suitable diet. Disturbances of the Heart The manufacture of lactic acid is an industry of less extent than that of acetic acid, and yet it is one which has some considerable commercial importance. The Story of Germ Life Lactic Fermentation changes the sugar of milk, lactose, to lactic acid, i.e. sour milk. An Introduction to Chemical Science If we should begin with the digestive function, we should find that the long-agitated question of the nature of the acid of the gastric juice is becoming settled in favor of the lactic. Medical Essays, 1842-1882 When the milk has attained a certain degree of acidity, the lactic acid bacteria are unable to thrive and the souring process is slowed up and finally stopped. Maintaining Health Formerly Health and Efficiency The Vibria and the lactic ferments properly so called did not appear on account of the nature of the liquid. A History of Science — Volume 4 There are several different kinds of lactic acid. The Story of Germ Life When milk is allowed to stand for a while the sugar ferments, through the action of the lactic acid bacteria. Maintaining Health Formerly Health and Efficiency The sugar is turned into lactic acid, which combines with the casein and when this process has continued for a certain length of time the result is clabbered milk or sour milk. Maintaining Health Formerly Health and Efficiency Most of the other bacteria in milk perish when lactic acid is formed. Maintaining Health Formerly Health and Efficiency The lactic acid seems to have a sweetening effect on the alimentary tract. Maintaining Health Formerly Health and Efficiency It is due to the action of certain of the milk bacteria upon the milk sugar which converts it into lactic acid, and this acid gives the sour taste and curdles the milk. The Story of Germ Life It is believed that the lactic acid formed is one of the principal agents producing this softening. Maintaining Health Formerly Health and Efficiency |
