Abstract:
Cyathus stercoreus grown on wheat straw had a higher xylanase activity than when it was grown on rice husk or extracted hemicellulose. Inclusion of casein hydrolysate, Tween 80 and Mn(2+) (at 0.02%, 0.2% and 0.075%, respectively) increased the production of extracellular xylanase. Optimal yield of xylanase (0.73 U/ml) was at pH 5.6 after 9 to 12 days at 30°C. The xylanase was stable at pH 4.5 to 7.5 for 2h but above 50°C its stability fell sharply.

105
Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

01:27Production of Antibiotics
265
Penicillin, one of the earliest and most widely used antibiotics, is produced industrially by the filamentous fungus Penicillium chrysogenum. Large stirred-tank bioreactors ranging from tens to hundreds of thousands of liters maintain tightly controlled temperature, pH, and dissolved oxygen conditions to support fungal metabolism and maximize antibiotic yield. Penicillin is a secondary metabolite, synthesized primarily during the stationary growth phase, which requires a carefully managed...
