Antagonism by Aerobacter Strains

Antagonism by Aerobacter Strains.

The literature on the antagonistic action of members of the genus Aerobacter is rather scanty. Winslow and Cohen (1918a, 1918b) reported that when a mixture of 46 per cent BaciUus aerogenes cells and 54 per cent Bacillus coli cells suspended in unsterilized tap water was stored 60 days, only 29 per cent of the remaining cells were B. coli. A slight degree of antagonism might conceivably have ex...

The composition of the extracellular polysaccharides of Aerobacter-Klebsiella strains.

2. In the early stage of fat synthesis the fat is more acidic and contains a larger percentage of unsaponifiable substances than at any later period. 3. Until the stage of maximal activity of the mould is attained the actual amounts of both saturated and unsaturated component acids continue to increase, but in the subsequent phase ofthe life of the culture the weight of each of these components...

The fermentation of sucrose by Aerobacter aerogenes.

Physiology of nitrogen fixation by Aerobacter aerogenes.

Skinner (1928) tested 23 strains of Bacteriumn aerogenes (Aerobacter aerogenes) and reported that two, and possibly a third, assimilated gaseous nitrogen when cultured in liquid medium, a claim confirmed 27 years later by Hamilton and Wilson (1955) using the N" isotopic method. Their experiments indicated that A. aerogenes incorporated significant amounts of tracer and that anaerobically, in a ...

The Distribution of Polysaccharide Production in Aerobacter and Escherichia Strains and its relation to Antigenic Character

Strains of Aerobacter aerogenes, A. cloacae and Escherichia coli, including mucoid capsulate, mucoid non-capsulate, smooth and rough variant forms, were grown on defined agar media. The polysaccharide content of the cultures was estimated by the anthrone method and related to the amount of growth as measured by the non-dialysable nitrogen content. Polysaccharide production, as measured by the p...
