Concurrent production of cellulase and xylanase from Trichoderma reesei NCIM 1186: enhancement of production by desirability-based multi-objective method.

Application of multiple response optimizations using desirability function in the production of microbial metabolites improves economy and efficiency. Concurrent production of cellulase and xylanase in Trichoderma reesei NCIM 1186 using an agricultural weed, Prosopis juliflora pods, was studied. The main aim of the study was to optimize significant medium nutrient parameters for maximization of cellulase and xylanase by multi-objective optimization strategy using biomass.

Immobilization of levan-xylanase nanohybrid on an alginate bead improves xylanase stability at wide pH and temperature.

Despite the sustainable availability, levan, a fructose based natural polysaccharide has not received significant attention in the development of enzyme immobilization technology. Herein, we prepared levan-xylanase (LXy) nanohybrid and characterized by scanning electron microscopy, particle size analyzer and zeta potential. To prevent the enzyme leakage from the nanohybrid, LXy was immobilized onto an alginate beads (NaAlg).
