“…These enzymes are widely used in numerous application areas including the beverage, paper and textile industries, in agriculture, detergents and animal feeds, as well as serving as an important alternative source of energy generation. Some organic compounds are inducers for cellulase such as disaccharides, spent ammonium sulphite liquor (Han et al, 2017) and glycerol (da Silva Delabona et al, 2016). This research study aims to explore the isolation of polypore fungi and the production of endoglucanase enzyme.…”

Polypores are diverse macrofungi that have been extensively studied for their lignocellulolytic enzyme production capabilities. Currently, these enzymes are being used for many industrial purposes. However, the high cost associated with their production is the main barrier to their broader application. This work aimed to study the optimal medium and conditions for endoglucanase production using solid state fermentation. Seven polypore strains were used for endoglucanase activity screening. The fermentation experiments were carried out in 250 ml Erlenmeyer flasks with green tea waste as a substrate. Notably, Microporus xanthopus strain KA038 showed the best level of activity (38.62 IU/gds). Various parameters such as moisture content, nitrogen source, initial pH value, inoculum size and incubation time were considered to determine the optimal conditions for endoglucanase production. The optimal medium consisted of green tea leaves as a carbon source, beef extract as an organic nitrogen source, NH4H2PO4 as an inorganic nitrogen source, pH 7.0 and an incubation temperature at 30°C for 4 days resulted in a high enzyme yield with M. xanthopus strain KA038 (81.8 IU/gds)..

Polypores are diverse macrofungi that have been extensively studied for their enzyme production capabilities. Presently, these enzymes are being used for many industrial purposes. However, the high-cost associated with their production is the main barrier to their broader application. This work aimed to study the optimal medium and conditions by using solid state fermentation. Seven polypore strains were used for cellulase activity screening. The fermentation experiments were carried out in 250 mL Erlenmeyer flasks with green tea waste as a substrate. Notably, Microporus sp. KA038 showed the best level of activity of 81.8 IU/gds. Various parameters such as temperature on growth, moisture content, nitrogen source, initial pH value, inoculum size and incubation time were considered to determine the optimal conditions for cellulase production. The optimal medium consisted of green tea leaves as a carbon source, beef extract as an organic nitrogen source, and NH4H2PO4 as an inorganic nitrogen source, while pH 7.0 and an incubation temperature of 30°C for 4 days resulted in a high enzyme yield with Microporus sp.

“…In a study conducted by Han et al (2017), fermentation with continuous feeding of spent ammonium sulfite liquor was found to improve cellulase production by Penicillium oxalicum. Using a multi-stage feeding strategy, the highest filter paper enzyme activity was able to reach 17.66 U/mL when applied for 144 hours.…”
