In the course of our searching program on the microbial endophytes of medical plants (Cympobogon proximus, Anethum graveolens, Artemisia judaica and Corchorus olitorius), the endophytic strain Streptomyces sp. ESRAA- 301097 derived from Cympobogon proximus proved to be the hyper xylanase producer. Screening of various locally available agro-industrial residues as substrate support for xylanase production under SSF exhibited a mixture of wheat bran (WB); sugarcane bagasse (SCB) with corncob (CC) at a ratio of 0.5:1:1 as the efficient inducer for the induction of ESRAA-301097 xylanase production as it gave the highest enzyme productivity (2364 Ugds-1) at the 4th day of fermentation when compared to individual WB, SCB or CC (1167, 1241 or 1404 Ugds-1) after 3, 4 and 4 days of incubation. Xylanase production was enhanced to 3819 Ugds-1 after optimizing the physical process parameters incl.. View More»
