Abstract: To satisfy the requirement of research and production, it is important and necessary to obtain high xylanase-producing strain, which has great application potential of commercialization. Drawn from the relationship between enzyme activity and the site of sampling, we could draw some valuable conclusions about strain screening of high xylanase activity. For example, the samples should be taken from ligonocellulose rich and flat locations. In addition, we also reviewed the species of high xylanase activity producing microbe and the importance of carbon source optimization. This paper could provide some significant inferences about the screening of high yielding strain and fermentation optimization.

Key words: xylanase, strain screening, carbon source
