摘      要：In this study,coffee pulp(Coffea arabica)and green tea(Camellia sinensis)residues were characterized for use as a substrate of solid-state fermentation for cellulases *** invasion rate was evaluated,as well as cellulases production by strains of Aspergillus niger and Trichoderma asperellum from the western Ghats of India,on coffee pulp,green tea,and a mixture of both substrates(50:50).***(AFP)strain was found to have the highest growth rate(0.409±0.021 mm/h)using a mixture of both *** production of cellulases by *** was unsatisfactory due to the presence of polyphenols in the supports to which *** cellulases are more *** production of cellulases by *** was linked to the pH of the supports,favouring the use of T and *** was found that the extracts produced by ***(28A strain using a mixture substrate,28A,and 20A strains using only green tea as a substrate)presented the highest cellulase activities when evaluated using a plate technique producing degradation halos of 2.3±0.1 cm of *** 28A strain did not require mineral enrichment media for cellulase production using green tea residues as support of solid-state fermentation.
