Diversity and abundance of ammonia-oxidizing bacteria (AOB) revealed by PCR amplification of amoA gene in a polyacrylamide transportation system of an oilfield

Specific microbial diversity and functional gene (AOB amoA) analysis of a sponge-based aerobic nitrifying moving bed biofilm reactor exposed to typical pharmaceuticals

“…Microorganisms play an important biochemical role in nutrient recycling in the ecosystem, and their communities often exhibit high microbial diversity and respond to changes in environmental conditions (Li et al, 2016). Pollutants in biological wastewater treatment systems are mainly removed by biodegradation, thus microbial communities have J o u r n a l P r e -p r o o f 4 been regarded as the ultimate factor responsible for pollutants' removal (Fang et al, 2012).…”
