Bacterial Cell Metabolism under Anaerobic Conditions
Escherichia coli has been cultivated in a peptone water medium saturated continuously with nitrogen by use of a gas train so as to produce anaerobic conditions. Under these circumstances growth was greatly inhibited. Cultures which originally contained 11 million bacteria per cc. showed on the average only 32 million after 5 hours (as compared with 655 million in similar cultures saturated with...
متن کاملProducts of glucose metabolism by homofermentative streptococci under anaerobic conditions.
It is well recognized that products other than lactic acid may be produced by homofermentative lactic acid-producing streptococci. Small quantities of formic, acetic, propionic, and butyric acids, ethanol, carbon dioxide, 2,3-butanediol, acetoin, and biacetyl have been reported as metabolic products of these organisms (Hammer, 1920; Foster, 1921; Langwill, 1924; Long and Hammer, 1936). Of these...
متن کاملBacterial Cell Metabolism under Anaerobic
Since the days of Pasteur it has been known that under anaerobic conditions microorganisms display special powers of attacking carbohydrate molecules. As a rule, however, such observations have been made on mass cultures with no knowledge of the actual number of ceils concerned. In the ordinary routine bacteriological tests for fermentation, even the amount and type of gas produced is only conj...
متن کاملFactors Affecting Basal Metabolism
Superficial observations have led us to the general belief that the vital processes are much the same with average individuals. It is true that we are inclined to classify people as high-strung and nervous on the one hand and phlegmatic on the other; yet, on the average, the normal individual apparently has a metabolic plane comparable to his neighbor’s, for the general uniformity in the energy...
متن کاملFactors Affecting Pro-Environmental Attitudes
Using data from the fifth wave of the World Values Survey (2005-2008), this study examined the relationship between affluence, post-materialist values, and pro-environmental attitudes from individuals from Morocco, Uruguay, Sweden, and the United States. Demographic variables were also analyzed to determine which factors were the best predictors of pro-environmental attitudes from each of the f...
