Abstract


Jute caddies is one of the important waste products generated from the processing of jute fibres in jute mills, which cause serious pollution problem in and around the mill locality. These waste caddies were collected and utilized in the fermentation medium for submerged cultivation of a strain of Penicillium janthinellum as sole carbon source for the production of extra cellular endo xylanase. The strain showed best enzyme production at pH 8.0 and at a temperature of 28C and at a concentration of 2% (w/v) jute caddies. Gelatin and Mn2+ could increase the enzyme production up to certain extent. The kinetics of the enzyme production and substrate utilization showed that highest endoxylanase production could be achieved at 48 hour of growth and jute caddy was degraded as sole carbon source very slowly up to 72 hours, after which the rate of utilization increased.
