The utilization of acetate for synthesis in Escherichia coli.
For many years the importance of the Krebs tricarboxylic acid cycle in bacterial metabolism has been contested. Some authors find evidence for the occurrence of the cycle in certain species of bacteria; in other cases, results are interpreted as proving that the cycle does not operate (see Ajl for a recent review (1)). In most of these studies, as indeed with those on other organisms, the empha...
متن کاملUtilization of acetate by Tetrahymena geleii (S).
Tetrahymena geleii (S) (Colpidium camp&m) is a ciliated protozoan which has been shown to be capable of synthesizing lipides from protein at an unusually high rate (1, 2). The next obvious step in studies concerned with the metabolism of this organism, therefore, seemed to be a search for the compound, or compounds, serving as precursor of the lipide material. Acetate is known to play a key r&e...
متن کاملEffect of sodium acetate on expression of K99 pili by Escherichia coli.
Sodium acetate suppressed K99 production in Escherichia coli strains cultured on a minimal medium, as determined by seroagglutination and enzyme-linked immunosorbent assay. The greatest suppression occurred when the medium contained both sodium acetate and glucose. Glucose alone did not suppress K99 production.
متن کاملMechanisms and genetics of resistance to sodium lauryl sulfate in strains of Shigella and Escherichia coli.
The sensitivity to sodium lauryl sulfate (SLS) of Shigella flexneri and Escherichia coli is determined by at least three genes. One site is located near the lactose operon, and two loci are cotransducible with the arabinose operon. Calcium ions protect against SLS lysis. One gene is concerned with the relative ability of the bacterium to retain calcium against such chelating agents as ethylened...
متن کاملUtilization of C14 labeled pyruvate and acetate by yeast.
The metabolism of pyruvate and acetate has been widely investigated in a variety of organisms. Studies of pyruvate fermentation in yeast, as well as the aerobic metabolism of both compounds in animals and microorganisms, have established the import.ance of decarboxylation as an initial step in the anaerobic metabolism of pyruvate and of the central position of the Krebs tricarboxylic acid cycle...
