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...
متن کاملBacterial Fermentation
Under anaerobic conditions, in the dark and in the absence of electron acceptors, organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions, a process called fermentation. In fermentation, the organic compound serves as both electron donor and acceptor, and adenosine triphosphate is synthesized by substrate l...
متن کاملPenicillin Fermentation
The success of fermentation processes often depends upon the maintenance of an environment sufficient in oxygen concentration so as not to limit or impair normal respiratory activity. Maintenance of such an environment is, in turn, largely dependent on the adequacy of oxygen transfer from air to the liquid medium. Of the possible pathways for oxygen transport, absorption into the medium and sub...
متن کاملAntimycin A fermentation. II. Fermentation in aerated-agitated fermenters.
Fermentation characteristics, previously studied in shake flasks, were reproduced in aerated-agitated fermenters, using three strains of Streptomyces sp. which had been selected for their high antimycin A productivity in shake flasks. Fermentation in fermenters was run in three stages. The medium consisted of soy flour, glucose, ammonium sulfate and calcium carbonate; initial pH was 7.2 approxi...
متن کاملElectro-Fermentation - Merging Electrochemistry with Fermentation in Industrial Applications.
Electro-fermentation (EF) merges traditional industrial fermentation with electrochemistry. An imposed electrical field influences the fermentation environment and microbial metabolism in either a reductive or oxidative manner. The benefit of this approach is to produce target biochemicals with improved selectivity, increase carbon efficiency, limit the use of additives for redox balance or pH ...
