微生物絮凝剂及其产生菌的研究新进展

Research Progress of Bioflocculant and Flocculant-producing Bacteria

摘要:

介绍了近几年来国内外微生物絮凝剂及其产生菌的一些发展概况, 列举了近几年一些研究较深入的胞外生物高聚物絮凝剂的物质属性和化学组成。重点讨论了胞外生物高聚物絮凝剂的成分分析、絮凝机理以及影响絮凝活性的因素, 详细综述了絮凝剂产生菌的遗传学和代谢机理方面的研究进展, 文章最后提出微生物絮凝剂的发展趋势和研究方向。

Abstract:

The development survey of Extracellular Biopolymeric Flocculants (EBFs) and flocculant- producing bacteria were introduced; some EBFs discovered in recent years were listed with their properties and chemistry components. Components analyses and mechanisms of flocculation and the factors might influence the activity of EBFs were given emphasis to discuss, genetics and metabolic mechanism study on flocculant-producing bacteria were summarized in detail, and the development and study tendency of microbial flocculant were put forward.
