Enzymatic studies on the conversion of citric acid fermentation to polyol fermentation in hydrocarbon-assimilating yeast Candida zeylanoides.

Fermentation studies on Glutamic Acid Fermentation

The present study deals with the production of L Brevibacterium spp. The permeability of cells decide the extent of excretion of L which was modified using yeast extract, limitation of biotin and electropration. The amino acid concentration produced by fermentation was found to be 162mg /100 ml detected b spot in TLC. At 8 % culture density the yield was higher.(27.3mg/10 ml), 35 optimum for ma...

Chemical Regeneration of Exhausted Granular Activated Carbon Used in Citric Acid Fermentation Solution Decoloration

An improved chemical regeneration of the granular activated carbon (GAC) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (CAF) was investigated. In the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed GAC is 103% of original GAC. Using oxidan...

Aconitase and citric acid fermentation by Aspergillus niger.

In view of the often-cited theory that citric acid accumulation is caused by an inhibition of aconitase activity, the equilibrium of the reaction of aconitase was investigated by comparing in vivo steady-state concentrations of citrate and isocitrate in Aspergillus niger grown under various citric acid-producing conditions. With the equilibrium catalyzed by the A. niger enzyme in vitro, similar...

Effect of actidione (cycloheximide) on yeast fermentation.

Actidione, an antibiotic produced by Streptomyces griseus, is highly active against a large number of yeasts but it has no marked antibacterial activity. Of 22 species of yeasts tested by Whiffen (1948), 9 were completely inhibited by 0.17 jig drug per ml; Saccharomyces cerevisae required 10 ,ug per ml and 5 species were not inhibited by 1000 ,ug per ml. There appears to be little in the litera...
