Effects of carbon sources on enzyme production of Neocallimastix sp. ve Orpinomyces sp [Neocallimastix sp. ve Orpinomyces sp.'nin Enzim Üretimleri Üzerine Karbon Kaynaklari{dotless}ni{dotless}n Etkisi]

Neocallimastix sp. and orpinomyces sp. was grown by using 12 commercial carbon sources and 11 plant carbon sources. β-1,4-endoglucanase,β-1,4-endoxylanase,β-glucosidase,β-xylosidase synthesis by these fungi were determined. enzymes accumulated on culture medium after three days. the maximum cellulase activities of neocallimastix sp. and orpinomyces sp. was observed in the cultures of carboxymethyl cellulose and textile waste,respectively. in the cultures of readily fermentable sugars,cellulase activity was under 0.5 u/ml. xylanase activity was found to be maximum in carboxymethyl cellulose culture of neocallimastix sp. however maximum xylanase activities of orpinomyces sp. was found in fructose,maltose,sucrose,lactose and avicel cultures. xylanase production of both fungi was also induced by alfalfa hay. neocallimastix sp. produced more β-glicosidase and β-xylosidase than orpinomyces sp. inulin was fermented by both fungi,however inulin was the only substrate that caused poor growth and enzyme production. the continuous secretion of xylanase reflected the role of anaerobic fungi in hemicellulose degradation in host animal.
