Trichoderma harzianum strain and use thereof

The invention relates to Trichoderma harzianum Rifai WRF-2 and use thereof. The bacterium strain was preserved in China General Microbiological Culture Collection Center on January 21st, 2009, with a preservation number of CGMCC No.2870. The bacterium belongs to deuteromycetes and is a lower fungus that is short in culture period and quick in growing and propagating speed and produces a large amount of uniform culture liquid for lignin degrading enzyme-generating bacteria in a short time compared with a major part of basidiomycetes to which whiterot fungi belong. The invention also provides a method for culturing and producing lignin peroxydase (Lip) and manganese peroxidase (MnP) by the fermentation of the bacterial strain in a liquid enzyme-generating culture medium, which can produce high-acitivity LiP and MnP in a short time, and is simple in fermentation process, stable, low in cost, and high in yield.
