| Abstract: | Xylanases being used for several industrial
processes under harsh conditions must be robust. A Streptomyces sp. SU9 isolated from humus was found to produce
highly thermoactive (optimum temperature 80oC) and alkali-stable
(optimum pH 9.0) xylanase. The organism not only utilized agricultural-based
carbon sources like wheat bran and wheat straw, but produced xylanase titre
(5200 IU/L) higher than that obtained on pure xylan (2600 IU/L), rendering
economy to production and application. Yeast extract as nitrogen source
promoted maximum xylanase production compared to soybean meal and peptone. The
xylanase was stable over a pH range of 6-9. Thermoactivity of xylanase was
moderate as it inactivated upon incubation above 60oC for 30 min. |
