Application of thermoalkalophilic xylanase from Arthrobacter sp. MTCC 5214 in biobleaching of kraft pulp.

A thermoalkalophilic and cellulase-free xylanase produced from Arthrobacter sp. MTCC 5214 by solid-state fermentation using wheat bran as a carbon source was evaluated for prebleaching of kraft pulp. The UV absorption spectrum of the compounds released by enzyme treatment showed a characteristic peak at 280 nm, indicating the presence of lignin in the released colouring matter.

Purification and characterization of thermoalkalophilic xylanase isolated from the Enterobacter sp. MTCC 5112.

Thermoalkalophilic Enterobacter sp. MTCC 5112 was isolated from a sediment sample collected from the Mandovi estuary on the west coast of India. This culture produced extracellular xylanase.
