Xxxvi. the Production of Acetaldehyde during the Anaerobic Fermentation of Glucose by Bacillus Coli Communis
Acetaldehyde has long been known as a product of alcoholic fermentation by yeast [see Roeser, 1893]. It has likewise been found to be formed by the leaves of higher plants when their metabolism is restricted to anaerobic conditions [Kostytschew, 1913]. In view of this wide distribution, it was to be expected that acetaldehyde would be a product of bacterial fermentation. This is the case. The q...
متن کاملOn the Chemistry of Bacillus Coli Communis. by Mary F. Leach
For the past few years, large incubating tanks have been in use in this laboratory for raising pure cultures of bacteria upon solid media. Each tank provides twenty square feet of growing surface, and yields under favorable conditions from thirty to fifty grams of air-dried cell substance. Thus it is possible to obtain sufficient material to make a systematic study of the chemical composition o...
متن کاملPleomorphism and Pleobiosis of Bacillus Bifidus Communis
From the foregoing experiments, the conclusion may be drawn that B. bifidus communis of Tissier has an aerobic phase, in which it resembles B. mesentericus fuscus. Numerous intermediate phases can occur between these two extremes; and their morphological and biological variabilities demand the utmost attention in order to interpret more intelligently the various phases of a given organism, cons...
متن کاملComparison of sterilization reaction rate for Bacillus subtilis and Escherichia coli using UV-visible spectroscopy
Sterilization is a process that eliminates or kills all microbes, including transmissible agents present on a surface, contained in a fluid, medication or biological culture media (UCLA Department Epidemiology). Dry heat sterilization is one of the important methods of eliminating microbes, as it coagulates the proteins in an organism, causing oxidative free radical damage thus leading to cell ...
متن کاملThe gastric neutral-red excretion test.
as a measure of gastric function, and various standardized tests have been devised. Owing, however, to the wide range of acid secretion in normal people, to the inconstant results obtained by repeating a test on many individuals, to the frequent occurrence of results well within the normal range in patients suffering from gastritis, gastric carcinoma, or peptic ulcer, and to the fact that from ...
