Xylanase production by Aspergillus niger AD-81 using Saccharum munja as substrate under solid state fermentation
Keywords:
xylan, hydrolyseAbstract
Xylanase are the industrially important class of the hydrolysing enzymes which hydrolyse xylan. Xylan is the most abundant of the hemicellulose which are linear backbone of beta-1,4 linked D-xylopyronase. Xylanase production can be performed on a variety of lignocellulosic material, such as wheat bran, wheat straw, rice husk, rice bran, rice straw, corncob, corn stalk, sorghum straw, apple pomace and sugarcane bagasse have been found to be most suitable. Microbial xylanase which is produced from fungus is most stable. Fungal species of Aspergillus, Trichoderma and Penicillium are mainly used for the production of xylanase at industrial scale. Xylanase have wide application in industry like food, feed, and pulp or paper industry. In the present study, Aspergillus niger AD-81 was used for the production of xylanase which was isolated from soil sample by serial dilution method. Whole fermentation process was carried out in 250 mL Erlenmeyer flask. Saccharum munja was used as substrate for xylanase production by Aspergillus niger AD-81 under submerged fermentation.
