Abstract
The aim of this work was to study the effects of key trace elements (i.e., iron, copper and molybdenum) on the development of co-cultured n-damo and methanogenic bacteria consortium, which could realize in situ CH4 production and utilization. The results showed that rational dosage, which was 50â¯mg/L of Fe, 1â¯mg/L of Cu and 5â¯mg/L of Mo, significantly stimulated the removal of NO2â. However, the activity of microbes was noticeably inhibited at 5â¯mg/L of Cu and 1â¯mg/L of Mo. Microbial community analysis indicated that the abundances of n-damo bacteria and methanogens showed a positive response to the rational dosage. Furthermore, the expression of key functional genes was enhanced under the rational dosage condition.
