Production of alpha-amylase and xylanase by an alkalophilic strain of Penicillium griseoroseum RR-99.
An alkalophilic strain of Penicillium sp. RR 99 was isolated that was found to synthesise extra-cellular alpha-amylase and xylanase, when cultivated in presence of starch and xylan respectively. The strain showed maximum alpha-amylolytic activity on 4th day and maximum xylanolytic activity on 6th day of cultivation. The ability of the strain to hydrolyse starchy and hemicellulosic wastes made the strain competent not only for the commercial production of these enzymes but also for successful utilization of wastes.
