摘要

The present study pertains to stimulation of enzyme secretion in a xylanolytic alkalophilic Bacillus in submerged culture in media supplemented with different zeolites. Among different zeolites possessing various cations, only calcium-containing zeolites exhibited two-fold enhancement of extracellular xylanase activity. 0.5% calcium zeolite enhanced the level of activity to the same extent as 0.5% Tween 80 supplementation. The possibility of supplementing zeolite as an alternative to Tween 80 in large-scale, aerated-agitated fermentations is discussed. [References: 14]
