Influence of growth substrate on production of cellulase enzymes by Trichoderma harzianum E58

M Mes-HartreeJ N Saddler


Cellulase production by Trichoderma harzianum E58 grown on lactose and various cellulosic substrates such as Solka Floe, Avicel, and steamed aspenwood was investigated. The culture filtrates of T. harzianum E58 obtained after growth on these substrates were assayed for their cellulase activities and overall hydrolytic activities. The severity of the steaming conditions used for the aspenwood had a pronounced effect on the cellulolytic activity of the produced culture filtrates. Those substrates that were more readily hydrolyzed by the cellulase complex were the poorest substrates for inducing an active cellulase complex. Substrates such as acid-impregnated aspenwood and lactose induced a less hydrolytic efficient cellulase complex than more recalcitrant substrates such as microcrystalline cellulose.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
