Glucose-induced changes in the bacterial communities of mine tailings at different acidification stages.

Ecological restoration technologies applied to tailings can influence the associated bacterial communities. However, whether the shifts in these bacterial communities are caused by increased organic carbon, is unknown. Glucose-induced respiration and high-throughput sequencing were used to assess the microbial activity and bacterial communities, respectively. Glucose addition increased the microbial activity, and glucose-ammonium nitrate addition resulted in slightly higher CO2 emission than did glucose addition alone, suggesting that carbon and nitrogen limited microbial community growth. In neutral pH tailings, the bacterial taxa that increased by glucose addition were assigned to the phyla Proteobacteria, Acidobacteria, Actinobacteria, Bacteroidetes, Firmicutes and Planctomycetes. However, the bacterial taxa that increased by glucose addition in acidic tailings only belonged to the phylum Actinobacteria (maximum increase of 43.78%). In addition, the abundances of the total nitrogen-fixing genera and that of the genus Arthrobacter (representing approximately 97.89% of the total nitrogen-fixing genera) increased by glucose addition in acidic tailings (maximum increase of 46.98%). In contrast, the relative abundances of the total iron- and/or sulfur-oxidizing bacteria decreased (maximum decrease of 10.41%) in response to the addition of glucose. These findings indicate that the addition of organic carbon is beneficial to the development of bacterial communities in mine tailings.
