چکیده انگلیسی
The suitability of L-arabinose-rich plant hydrolysates as carbon sources and inducers of xylanase production in Trichoderma reesei Rut C-30 was tested. Significantly higher xylanase activities were obtained in cultures on oat husk and sugar beet pulp hydrolysates than on lactose. In batch culture with oat husk hydrolysate and lactose, the xylanase activity was about 9 times higher (â¼510Â IU/ml) than in lactose (â¼60Â IU/ml). Even higher xylanase activity (â¼630Â IU/ml) was obtained when the batch cultivations were done on sugar beet pulp hydrolysate and lactose. In a fed-batch culture using oat husk hydrolysate-lactose the xylanase activity was as high as 1350Â IU/ml in 4 days. The cellulase production clearly decreased when T. reesei was cultured on both hydrolysates compared to the cultivation on lactose. Moreover, the relative amounts of the xylanases I-III were similar regardless the used carbon source.
