Abstract

A pectin degradation enzymes are widely used in the industrial processing of fruits and vegetables in order to decrease the viscosity of juices and thus to facilitate extraction, maceration, liquefaction, filtration and clarification processes. Sugar-cane bagasse (SCB) was used as the substrate for pectinases from T. lanuginosus at 55癈 under solid-state fermentation (SSF) culture. Exo-PG and total PNL & PL enzymes were purified using Gel-filtration chromatography; the former exhibited only one sharp peak, while the latter showed two identical peaks each of them represents one enzyme. Biotechnological applications of fermented bagasse obtained mixed with the fungal biomass at 55癈 as biofertilizer at different concentrations (w/w) were cultivated with Zea mays for 30 days to indicate the growth on sandy soil and succeeded to induce the plant growth which may give an indication of applying the present biofertilizer particularly in the reclaimed sandy soils. Only 14 and 13 amino acids were detected and obviously that Exo-PG was typical proline containing enzyme and total PNL & PL were glycine/histidine containing enzymes, respectively.
