A novel bacteria strain Pseudomonas stutzeri capable of producing xylanase, which is deposited at the MCMRD, National Institute of Oceanography, Dona Paula, Goa 403004, India and having the assession number MCMRD-AB-001 and also deposited at ______ having accession No. ______.
A process for the preparation of alkalophilic and thermophilic extracellular enzyme xylanase from a novel bacteria strain Pseudomonas stutzeri deposited at MCMRD, National Institute of Oceanography, Dona Paula, Goa 403004, India having the assession number MCMRD-AB-001 and also deposited at ______ having accession No. ______, said process comprising cultivating Pseudomonas stutzeri in a conventional nutrient medium, separating cells from supernant by any conventional method followed by recovery and purification of the xylanase from the supernanat by any conventional method.
A process as claimed in claim 8, wherein the xylanase shows activity at pH values between 5.5 and 9.5, and temperature of 80° to 100° C.
A process as claimed in claim 8, wherein the xylanase is capable of retaining 42% its activity when sterilized at 120° C. and 15 lb pressure for 10 minutes.
