Abstract
Six species of white rot fungi i.e. Pleurotus citrinopileatus, P. eryngii, P. flabellatus, P. florida, P. ostreatus and P. snjor-caju were grown on wheat straw under in vitro as well as in vivo condition. Maximum activity of xylanase (3.2.1.8) under in vitro condition was observed on the 10"' day of incubation by P. ertingii (23.33 Uh-1mL-') followed by P. citrinopileatus (20.88 Uh-imL-') and P. ostreatus (13.33 UhlmL-1) on the 15'h day. After 15" day there was decrease in the enzyme activities till the end of the experiment. Under in vivo condition also P. eryngii showed maximum xylanase activity on hot water treated (21.88 UhlmL-') as well as chemically treated (1.2.64 Uh-1mL-1) wheat straw. Hot water treated substrate supported better production of the enzyme than chemically treated substrate.
