%X Twelve anaerobic fungal strains isolated from rumen and faeces of ruminants were screened for xylanase prodution. Isolate A4 strain identified as Neocallimastix had the highest xylanase activity among all isolates. With rice straw, corn straw , peanut straw and filter paper as fermentation substrates, the activities of xylanase by A4 were14.31 U/mL, 11.39 U/mL, 6.99 U/mL, 13.38 U/mL, respectively. The effect of cell-free rumen fluid and yeast extract on xylanase production was tested. The results showed that the concentration level of cell-free rumen fluid had no significant effect on xylanase production. However as yeast extract concentration decreased from 1.0 g/L to 0,5 g/L , the enzyme activity decreased significantly ( P < 0.05) .
