6-aminopenicillanic acid: inhibition of destruction of cephalosporin c by bacteria.6-aminopenicillanic acid, from which all the true penicillins are derived, inhibits the destruction of cephalosporin c by certain microorganisms. this inhibition is probably specific for "cephalosporinase." the enzymatic deacetylation of cephalosporin c is not affected by the acid.196414107444

use of cheese whey for vitamin b12 production. i. whey solids and yeast extract levels.the suitability of cheese whey as a substrate for vitamin b(12) production by propionibacterium shermanii was studied. it was found that with a given level of whey solids a definite amount of yeast extract was required to give maximal yields of vitamin b(12). of the levels of materials studied, 10% whey solids and 1.5% yeast extract gave the best yields of vitamin b(12). most of the lactose of the whey had been utilized in all flask cultures after 168 hr at 29 c.19665970817
use of cheese whey for vitamin b12 production. ii. cobalt, precursor, and aeration levels.within the limits of this study, it was found that 5 ppm of cobalt was adequate to give good levels of vitamin b(12). the vitamin b(12) precursor 5,6-dimethylbenzimidazole was found to be adequate at 10 ppm in the absence of aeration. in the presence of aeration, a zero level of precursor was found to be most desirable. the analysis of variance showed aeration to be highly significant, and the aeration and precursor interaction to be significant. no other significant effects were observed.19665970818
use of cheese whey for vitamin b12 production. 3. growth studies and dry-weight activity.the patterns of growth and vitamin formation by propionibacterium shermanii in whey were similar to the patterns established in other substrates. the vitamin formation was observed during the latter part of the fermentation after the organism approached maximal growth. lactose utilization by the organism corresponded to the logarithmic-growth phase of the organism. analyses of the dried culture showed a large increase of vitamin b(12) in the fermentation solids compared with unfermented dried wh ...19665970819
