Penicillium oxalicum WCF3 and application thereof

The invention discloses penicillium oxalicum WCF3 and application thereof, and belongs to the technical field of environmental biology, the penicillium oxalicum WCF3 is classified and named as penicillium oxalicum WCF3, the penicillium oxalicum WCF3 is preserved in China General Microbiological Culture Collection Center (CGMCC), the preservation number is CGMCC No.41119, and the penicillium oxalicum WCF3 is named as penicillium oxalicum WCF3. The penicillium oxalicum WCF3 has the activity of efficiently degrading cellulose and solubilizing phosphate, and has potential in the development of cellulose biodegradation strains; after the diluent of the penicillium oxalicum WCF3 and crop straws are turned over and returned to the field together, the utilization rate of phosphorus in the straws can be increased, the content of available phosphorus in soil is increased, and the use of chemical phosphate fertilizer is reduced. 本发明公开了一株草酸青霉WCF3及其应用，属于环境生物技术领域，其分类命名为草酸青霉(penicillium oxalicum)WCF3，保藏于中国微生物保藏管理委员会普通微生物中心(
