In an attempt to isolate xylanase from microbial sources, Streptomyces sp. CSWu-1 was recently isolated from Korean soil and identified according to various characteristics including 16S rRNA sequencing. The strain produced high xylanase activity (XynWu-1) in xylan medium. Production profile showed that the highest activity was produced at 80 h when cultivated at 28⁰C and 120rpm. The enzyme was optimally active at 50°C and at pH 11.0, suggesting that the enzyme is alkaline and moderately thermostable. One peculiar characteristic of XynWu-1 is that it was highly dependent on buffer concentration and it maximum activity was found below 25mM.
