The investigation of fungi’s cellulose degradation. A study at Ma Da forest, Dong Nai

Abstract

Ma Da forest is one of the important natural reserves in Vietnam. Its vegetation is a nutritional supplement to filamentous fungi and cellulase production. The enzymatic systems of fungi that can degrade native cellulose play an important role in the cycle of carbon. This study isolated and maintained 220 varieties of mold from 6 different soil samples collected from different places of Ma Da (Dong Nai). The identification method based on morphology identified 19 strains of Aspergillus niger, 3 strains of Curvularia sp., 9 strains of Penicillium lilacinum, 2 strains of Penicillium sp.1, 3 strains of Penicillium sp.2, 3 strains of Penicillium sp.3, 2 strains of Penicillium sp., 4 strains of Penicillium sp., 3 strains of Penicillium sp.6, 3 strains of Penicillium sp. 7 and 2 strains of Trichoderma sp. The investigation of cellulose degradation on Czapek-dox medium with 1% carboxyl methylcellulose (CMC) showed that all fungi were capable of cellulose degradation, including the genus Penicillium with high cellulose activity. The results of the study will be the prerequisite for further studies of the assessment of mold systems’ ability to return carbon to nature and to obtain molds with high cellulase activity for production.
