%X The biodegradation of chemically synthesized poly(3-hydroxybutyrate) (PHB) films was studied by the basidiomycetes,activated sludge,soil,and seawater experiments.It was found that PHB-degrading microorganisms are widely distributed in natural environments;hydrolytic and acidic degradation shows little influence on biodegradation rate of PHB film (below 3.5%);the shake culture is unfavourable to the biodegradation of PHB12 and PHB27 for Coriolus versicolor 5.48(degraded 17.8% and 13.5% at the 20th day respectively);the biodegradability of PHB film decreases with an increase in its crystallinity,which has a stronger influence over its biodegradation than the molecular weight.
