Penicillium oxalicum and application thereof

The invention provides penicillium oxalicum M which is a novel penicillium fungus strain. The penicillium oxalicum M can be cultured for a short time to obtain a large number of homogeneous cellulose degrading enzyme producing bacteria culture solution. The invention further provides a method for producing endoglucanase and exoglucanase by fermenting and culturing the penicillium oxalicum M in a liquid enzyme producing culture medium and a method for producing enzymatic saccharification straw cellulose by fermenting the penicillium oxalicum M. The processes are simple and stable, have low cost and can achieve high yield.
