光照混菌培养应用研究进展

光合细菌与其他微生物在光照条件下混合培养是近年来的研究热点。综述了光照混菌培养的特点和目前光照混菌培养在水体净化、生物制氢和高价值物质生产方面的应用，并对影响混合菌株生长代谢与繁殖的因素做了总结。分析表明菌株之间存在的相互协同共生作用能促进微生物的生长繁殖，使底物被充分利用，提高物质产率。光照混菌培养工艺简单、成本较低，在水体净化、生物制氢、高价值物质生产方面的应用具有相当好的效果。在影响因素中对混合培养影响最大的因素是菌株接种量、接种比和培养基pH。在总结光照混菌培养应用现存不足的基础上，对其发展前景作出展望。

Research Progress on Application of Photosynthetic Microbial Mixed Culture

Mixed culture of photosynthetic bacteria and other microorganisms under illumination has been extensively studied in recent years. The characteristic and applications (wastewater treatment, new energy production and materials production with high quality) of photosynthetic microbial mixed culture were analyzed, as well as factors on growth, metabolism and reproduction of mixed culture. The results showed that cooperation among microorganisms could promote the growth and reproduction of microorganisms, enhance the substrate utilization, and improve the production rate. Photosynthetic microbial mixed culture had the advantages of simple process, low cost, and high efficiency in wastewater treatment, new energy production and materials production with high quality. Among the factors that influence photosynthetic microbial mix culture, the most important ones were microbial dosage, proportion of mixed microorganisms, and pH of the culture. Based on the shortcomings of photosynthetic microbial mixed culture, some suggestions on the development were proposed.
