非晶颗粒态木薯淀粉微生物降解特性

Study on Degradative Characteristics of Tapioca Starch with Non-Crystallized Granule State by Microorganisms

摘要:

采用光学显微分析方法,以原木薯淀粉为参照,对非晶颗粒态木薯淀粉在微生物作用下的降解过程进行了观察和研究. 结果发现,在微生物作用下,从淀粉颗粒的爆裂孔开始,沿着淀粉颗粒爆裂孔逐步深入,直至最后将淀粉颗粒完全降解,而原淀粉颗粒具有致密的结晶结构,淀粉颗粒表面没有明显的孔洞,因此在同样条件下,生物降解性能要远远低于非晶颗粒态淀粉.

Using the light microscope analytical method, the degradative process of tapioca starch with non-crystallized granule state by microorganisms was investigated in details. Beginning at the blowing out poles of starch granules, starch granules were graduall
