PROBLEM TO BE SOLVED: To provide a PVA-degrading bacterium exhibiting excellent degrading/assimilating ability by itself on various kinds of PVA derivatives and to provide a method for degrading/assimilating PVA by using the bacterium and to provide a method for degrading and assimilating PVA, in which a microbial group including the bacterium exhibits high PVA degradation activity even under environment in which source of nutrition such as gelatin or starch capable of readily being assimilated by microorganisms exists. SOLUTION: The method for degrading a polyvinyl alcohol or a polyvinyl alcohol derivative comprises bringing a bacterium of the genus Comamonas, a microbial group containing the bacterium or a bacterial cell component of the bacterium into contact with polyvinyl alcohol or a polyvinyl alcohol derivative.
