微生物对淀粉塑料薄膜降解能力的研究

Study on the Degradation Effect of Microbe on Starch-Plastic Film

摘要: 报道用混合霉菌对淀粉塑料薄膜进行微生物降解的实验室方法和降解效果。将６种被接种的薄膜试片置于２８℃恒温条件下，经过２８天的培养，试片降解效果为：混合霉菌生长覆盖面积达２５％～１００％；失重率为０．６７％～１９．２６％；抗拉强度降低９０％以上；断裂伸长率降低１２．７％～３７．２％。证明混合霉菌对淀粉薄膜有良好的降解能力

Abstract: The paper reports the experimental methods and the effects of microbe degradation on different kinds of starch-plastic film inoculated with mixed fungi. The degradation effects of inoculated film are that the area of the fungi growth on film is 25 %～100 % , the film weight losses 0. 67 %～19. 26 % , tensile strenght decreases more than 90 % and breaking elongation decreases 12. 7 %～37. 2 %. So , the mixed fungi have a good degradation effect on starch-plastic film.
