MATH法表征环境微生物细胞表面疏水性的研究进展

Recent progress on MATH characterizing the cell surface hydrophobicity of environmental microorganisms

摘要:

环境微生物的细胞表面疏水性对其生长代谢过程以及在环境领域的应用效率具有重要影响。目前用于测试细胞表面疏水性最常用的方法是碳氢吸附能力(Microbial adhesion to hydrocarbons，MATH)，该方法因具有操作简便、有一定的准确度等优点在环境、生物工程、医学、食品等领域应用广泛。本文综述了MATH法在环境微生物领域中的污泥絮体性能表征、有机物降解、膜污染和破乳方面的应用，同时介绍了MATH法在实验操作、计数方法和数据分析方面的优化。最后展望了该方法今后的研究方向。

Abstract:

The cell surface hydrophobicity of environmental microorganism has important influence on its metabolism during cell growth process, and had wide applications in the field of environmental biotechnology. Currently, microbial adhesion to hydrocarbon (MATH) was popularly employed for characterizing the cell surface hydrophobicity. This method was widely used in environmental remediation, bioengineering, medical and food processing field owing to its advantages of simplicity, convenience and accuracy. This paper reviewed recent studies of MATH applied in sludge characteristic, degradation of refractory organics, membrane fouling and biological demulsification. The modified studies on MATH were also introduced in operating factors, counting methods and data analysis. Finally, the future research prospect in this field was also proposed.
