چکیده مقاله:

Cellulase production by the fungus Trichoderma reesei was studied using sugar beet pulp (SBP) as a substrate. The subculture medium was a salt solution consisting of KH2PO4, CaCl2, etc. Fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°C for 1-2 generations (two days for each generation) and were then used as an inoculum. Exponential cells were inoculated into a medium containing SBP. Data showed that cellulose in SBP has a potential to be used as a substrate to produce cellulase. The effect of cellulose concentration on cellulase production was investigated. Using the medium composition (the mixture of chemical salts and SBP substrate) and a fermentation time of 4-6 days, a maximum cellulase activity of 0.46 IU/ml of filter paper activity was obtained.

Increased Production and Activity of Cellulase Enzyme of Trichoderma reesei by Using Gibberellin Hormone

Cellulolytic complex are enzymes capable of hydrolyzing cellulose. Due to rapid growth in population and industrialization, most countries are required to produce more fuel. Production of bioethanol from lignocellulosic biomass is very challenging due to environmental pollution by fossil fuels. Cellulases play a significant role in biotechnological processes. The cost of production of cellulase...

Production of Cellulase-free Xylanase by Trichoderma Reesei Saf3

A xylanase producing fungi has been isolated from soil and identified as Trichoderma reesei SAF3. Maximum growth of the organism was found at 48 h under submerged condition in xylan containing enriched medium, whereas highest enzyme production (4.75U/mL) was recorded at 72 h. No detectable cellulase activity was noted during whole cultivation period. The partially purified enzyme hydrolyzed xyl...

Solid-State Fermentation with Trichoderma reesei for Cellulase Production.

Cellulase yields of 250 to 430 IU/g of cellulose were recorded in a new approach to solid-state fermentation of wheat straw with Trichoderma reesei QMY-1. This is an increase of ca. 72% compared with the yields (160 to 250 IU/g of cellulose) in liquid-state fermentation reported in the literature. High cellulase activity (16 to 17 IU/ml) per unit volume of enzyme broth and high yields of cellul...
