MOLECULAR CONFIRMATION, IDENTIFICATION AND INFLUENCE OF CARBON SOURCE FOR THE PRODUCTION OF XYLANASE FROM PENICILLIUM CITRINUM

摘要

Recently, xylanases have expanded their use in many processing industries, such as pulp and paper, food and textile to newer needs such as biofuel production. .This study were taken up to the enhance the biosynthesis of xylanase by supplementation of carbon sources were employed in range of 0.25% to 1.0%. The carbon source were supplemented are glucose, sucrose and maltose. The beef extract and ammonium nitrate were yielded higher xylnase production and showed 7.5 IU and 8.4 IU. Key words: Xylanase, submerged fermentation, xylose, fermentation kinetics and inoculums size.
