Characteristics and the use as culture media of protein hydrolysate from Locusta migratoria were determined in comparison with different peptones. After powdering, it was hydrolyzed chemically (acid hydrolysis) obtained product Locust Peptone (LP). The contents protein, fat, nitrogen, ash, minerals, total sugars amino acids LP seen that has both organic inorganic materials enough to a component...

AbstractInvestigation of alkaline protease production under different fermentation conditions using one factor at a time involving temperature, pH, incubation as well carbon and organic nitrogen sources .The results showed that the maximum activity (470U/ml) was obtained peptone 7.5 (g/L), glucose 5 pH 10, 24h 35oC. Further more, Two sequential statistical designs were used to optimize these ph...

month were wholly extractives. At the end of the third month, ?38 per cent, of serum albumin and -0734 per cent, of urea were present, with a trace of albumose and peptone. The third, obtained after six months, on the other hand, contained -7 per cent, of coagulable proteid, only *08 per cent, of this being serum globulin, and '1685 per cent, of the different albumoses, of which deuteroalbumose...

Bio peptone is a combination of enzymatic digest of animal tissues and casein; and generally used for the growth of several varieties of microbes. The aim of present study was to investigate the impact of biofield energy treatment on the physicochemical and spectroscopic properties of bio peptone. The present study was carried out in two groups i.e. control and treated. The control group was ke...

xanthan gum is an extracellular polysaccharide produced by various xanthomonas species such as x. campestris . the objective of present study was to investigate the influence of different carbon and nitrogen sources on xanthan gum production by x. campestris . using an experimental response surface methodology (rsm) complemented with a central composite design (ccd), the impact of peptone, lact...

the optimization of cell culture conditions for growth and productivity of recombinant chinese hamster ovary (cho) cells is a critical step in biopharmaceutical manufacturing. in the present study, the effects of the timing and amount of peptone feeding of a recombinant cho cell line grown in a basal medium in serum-free suspension culture were determined for eight peptones of different origin ...

Spores of Clostridium bifermentans KMR-1 were produced for use as a microbial inoculum for bioremediation and were preserved in both liquid and dry forms. All spore formulations showed good viability and ability to biodegrade the target compound, 2,4,6-trinitrotoluene (TNT), after 4 months of storage. For low-cost bulk spore production, several medium compositions, based on soy peptone, corn st...

One fluorescent compound previously named TDP-2 was isolated and purified from a rice culture of Fusarium equiseti (Alaska 2-2). Mass spectral and nuclear magnetic resonance data indicated that it is a C-3'-N-acetyl derivative of fusarochromanone, a newly discovered mycotoxin. Time course studies of synthesis of these two compounds on autoclaved rice and Czapek-Dox medium enriched with soybean ...

The production of thermostable extracellular protease by Bacillus stearothermophilus F1 was influenced by the composition of culture medium. Peptone iv derived from soybean was the best organic compound for enzyme production. Sodium nitrate, ammonium salts and amino acids as sole nitrogen sources interfered with protease formation. The addition of most carbon sources to the peptone medium faile...
