The residual ash content in the straw degraded by P. chrysosporium was maximum (220 g kg−1), which was followed by C. subvermispora (134 g kg−1). Phlebia radiata, P. floridensis and P. fascicularia had almost similar ash content of 130–132 g kg−1 followed by P. brevispora (126 g kg−1). Crude protein was maximum in PS degraded by P. brevispora (40·8 g kg−1) followed by P. radiata (36·4 g kg−1), P. chrysosporium (35·5 g kg−1) P. floridensis (32·5 g kg−1), C. subvermispora (29·9 g kg−1) and P. fascicularia (28·4 g kg−1) after 60 days of incubation.
Maximum laccase activity was shown by P. floridensis followed by P. radiata, C. subvermispora and P. brevispora on 30th day of incubation, respectively. Phlebia fascicularia was the poorest, although its laccase activity peaked on 20th day, while P. chrysosporium was not able to produce detectable laccase during the experimental conditions (Fig. 1). Xylanase production was maximum in P. radiata on 30th day while P. chrysosporium produced a maximum amount on 20th day, which decreased gradually during further incubation and the profile was similarly followed by C. subvermispora. Phlebia fascicularia produced maximum xylanase on 30th day, whereas P. brevispora and P. floridensis produced maximum xylanase on 60th day (Fig. 2). CMCase was maximum produced by P. chrysosporium on 30th day and similarly followed by C. subvermispora. Phlebia radiata and P. floridensis also produced maximum CMCase on 30th day while P. brevispora had almost similar enzyme production on 30th and 60th day. In the case of P. fascicularia, CMCase activity was gradually increasing up to the end of experiment (Fig. 3).
