淀粉基高吸水树脂降解菌的筛选及初步鉴定*

以淀粉接枝丙烯酸高吸水树脂为唯一碳源，从土壤中筛选出4个菌株，纯化后进行菌种鉴定。经过表面观察和理化实验，初步鉴定出它们分别为两类放线菌(放线菌科，Actinomycetaceaes和固氮菌科，Azotobacteraceae)、酵母菌(隐球酵母科，红酵母属，Rhodotonda)和霉菌(毛霉科，根霉属，Rhizopus sp．)，为深入研究高吸水树脂的降解性能提供参考。

The Screening and Identification of Strains Biodegrading Superabsorbent

Using the superabsorbent of starch graft sodium acrylate copolymer as the only carbon source, 4 excellent strains which can utilize the synthesized superabsorbent were obtained from soil after one month's screening and purification, then the taxa of the strain were identified, i.e., two kind of actinomycetes, yeast and mould.The result shows that the superabsorbent can be degraded successfully.
