Insights into bacterial diversity in industrial post-processing water from underground coal gasification (UCG) process

Archives of Environmental Protection
This study represents the first culture-independent profiling of microbial diversity in post-processing wastewater from underground coal gasification (UCG) processes. Three types of post-processing wastewater, named W1, W2 and W3, were obtained from three UCG processes involving two types of coal and two gasification agents, namely oxygen-enriched air ...
