摘要
综述了白腐真菌的生物学特性、悬浮和固定化培养白腐真菌降解染料以及白腐真菌生物反应器的研究现状,指出目前国内外研究白腐真菌降解染料中存在的主要问题是大部分研究均是在无菌操作下进行的,即无论是反应器、培养基还是载体,甚至含有染料的废水都是先经过灭菌后再投到反应器中的,而且整个降解过程也是严格控制在无菌条件下运行.这样,造成该项技术仍然停留在实验室研究阶段,应用到实际工程中的案例基本没有.分析制约该项技术应用到实际工程中的原因是反应体系的染菌问题.因此,针对目前研究中存在的问题,提出探索非灭菌环境下有效抑制杂菌生长的控制策略和抑菌机理是今后白腐真菌降解染料的研究方向.
The current status of research in the field of degradation of reactive dyes by white rot fungus is reviewed. For this purpose, the biological characteristic of white rot fungus and decolorization with suspended and immobilized cultures, and biological reactor, are discussed. The key problem in study of degradation of reactive dyes by white rot fungus is that the almost whole investigations are performed under sterile condition, i.e. the reactor, culture media, carrier and even wastewater are all sterilized. So almost all the studies both domestic and international using white rot fungi for dye wastewater treatment have rested on laboratory. There is no case of full scale application. A very important reason is of the bacterial contamination in reactor under non-sterile conditions. Aiming at this problem, we put forward that to develop the strategies for suppressing bacterial growth and to study the mechanism of suppressing bacterial growth are future development trends in degradation of reactive dyes by white rot fungus.
