Abstract

Studies were carried out to standardize a medium for the production of single cell protein (SCP) from alkali treated straw (ATS) by a strain of Penicillum chrysar genus. Ammonium dihydrogen phosphate and a combination of urea and ammonium sulphate were found to be the best sources of N. The optimum amounts were 500, 200, 200, 30 and 5 mg/l of medium. Addition of trace elements Fe, Mn, Co, Zn and Cu did not show any signficant increase in protein yield. Substrate concn. of 1-1.5% (w/v) was found to be most suitable for max. production of protein. No significant effect was observed when tap water was used in the place of distilled water for media preparation. The efficiency of the optimized medium was compared with 3 other standard media used to grow cellulolytic organisms. The production of SCP was scaled up to 40 l fermenter level. The product obtained from the fermenter after 72 h growth contained 34% crude protein, whereas that from the shake flasks contained 38-42% protein. 93-96% of the 74-76% cellulose originally present in ATS was utilized by the organism. The conversion of ATS to crude protein was about 19%.
