Corn is one of the richest sources for the production of ethanol. This project was carried out to study the optimum conditions for the production of ethanol. The parameters like, pH, Substrate concentration and particle size were optimized using response surface method in the MINITAB 16 software. Both solid and submerged fermentation were studied. Submerged fermentation turned out to be favoura...

The production of extracellular xylanase by a newly isolated fungus Simplicillium obclavatum MTCC 9604 was studied in solid-state and submerged fermentation. Multiple xylanases and endoglucanases were produced by the strain during growth on wheat bran in solid state fermentation (SSF). A single xylanase isoform was found to be produced by the same fungus under submerged fermentation (SF) using ...

Polyhydroxyalkanoates are biopolyesters stored as reserve source of energy by a great number of prokaryotes. It is stored as intracellular granules and during normal growth, its content in the cells usually does not reach high concentrations, usually in the range of 2–10 %, but the PHB contents can reach more than 80 % of the dry biomass if growth is limited by depletion of an essential nutriti...

There has been a steady increase in the consumption of citric acid during the past 25 years. An estimate by Cochrane (1948) places annual manufacture at approximately 35 million pounds. Commercial production of citric acid is reputedly based on fermentation by Aspergillus niger of a suitable grade of beet syrup in shallow pans. A submerged process appears to be highly desirable, and many articl...

Cyclosporin A (CyA) is found as an antibiotics, exhibiting immunosuppressive and antifungal properties. Cyclosporine A has been synthesized in large quantities by fermentation process using various fungal species such as Tolypocladium, Trichoderma, Fusarium Penicillium and Aspergillus spp. Submerged liquid fermentation (SLF) and solid state fermentation (SSF) have been used successfully to prod...

BACKGROUND AND PURPOSE Over the last decade, Agaricus blazei Murrill has been studied and developed as a novel functional food in Japan, Korea, China, and Taiwan. Due to the low yields, the fruiting bodies of A. blazei Murrill are relatively expensive, and a cheap and stable source of A. blazei Murrill mycelium for commercial purposes is highly desirable. Culture media and conditions were inves...

Humic acids (HA) were produced by a Trichoderma viride strain under submerged fermentation in a medium based on the oil palm empty fruit bunch (EFB) and the main variables of the process were optimized by using response surface methodology. A temperature of 40°C and concentrations of 50g/L EFB, 5.7g/L potato peptone and 0.11g/L (NH4)2SO4 were the optimum levels of the variables that maximize th...
