Compositions and properties of microbial residues formed by three single species fungi and mixed strains in cellulose-containing liquid media

The microbial residues, due to their closely connection with humic substances (HS), aroused our considerable interest. The method of shake-flask in liquid culture was adopt to accumulate them, in which the cellulose served as the sole C source. The microbial suspensions including Trichoderma viride...
