Characterization of bacteroides melaninogenicus.
Fifty-eight human isolates of Bacteroides melaninogenicus, 42 from a variety of clinical infections and the rest from normal flora, were studied for pigment production and ultraviolet light fluorescence and by forty biochemical and other tests, including end-product analysis by gas-liquid chromatography. In a number of instances, tests were repeated several times and the results were reproducib...
متن کاملLipids of Bacteroides melaninogenicus.
The lipids of Bacteroides melaninogenicus were readily extractable with chloroform-methanol. Three per cent of the fatty acids were not extractable. The neutral lipids contained 4% of the extractable fatty acids, the stench characteristic of these organisms, and 0.5 mumole of vitamin K(2) isoprenologues K(2)-35, K(2)-40, and K(2)-45 per g (dry weight). This is one-fifth to one-tenth of the vita...
متن کاملNotes on bacteroides melaninogenicus.
element is still in doubt. Efforts are being directed toward the interpretation of the structures which can be visualized in bacteria (DeLamater, Ann. Rev. Microbiol, 8, 23, 1954). The description and (lemonstration of the nuclear configurations found in normal vegetative cells of S. typhosa form the basis for comparison with cells treated with colchicine described by Minsavage and DeLamater (J...
متن کاملGrowth Factor for Bacteroides melaninogenicus
was found to be an additional growth factor in that this compound can replace the requirement for heme in the presence of vitamin K, allowing good growth of the organism, and succinate can also partially replace the requirement for vitamin K in the presence of heme. The addition of succinate to a medium supplemented with both vitamin K and heme increases the growth rate of the culture. This abi...
متن کاملInfluence of amino acids on the growth of Bacteroides melaninogenicus.
Addition of individual amino acids to a Trypticase-yeast extract-hemin medium affected growth rates and final yields of an asaccharolytic strain and a saccharolytic strain of Bacteroides melaninogenicus. L-Aspartate or L-asparagine produced maximal growth enhancement for both strains. L-[14C]aspartate was fermented by resting cells of the asaccharolytic strain. L-Cysteine or L-serine also enhan...
