Present investigation was done for screening microorganism with highly stable xylanase production. In present days, commercial microbial enzymes are increasingly replacing conventional chemical catalysts in many industrial processes. In current studies 56 actinomycetes were found positive for xylan-degradation. Among all isolates, best actinobacter found for xylanase production was rare species and less identified for any such properties. During studies Microbacterium hatanonis HAX-5 was found potential for xylanase production in submerged fermentation using agrowaste.
