Abstract:
We investigated microbial diversity in a manure storage tank (MST) storing untreated manure and an aeration tank (AT) during swine manure treatment process using the next-generation sequencing in order to find the aeration effect on microbial diversity. Proteobacteria were more abundant in the AT group than in the MST group and may include denitrifying bacteria contributing to nitrous oxide (N2O) emission or aerobic bacteria stimulated by oxygen. The opposite held true for the phyla Bacteroidetes and Firmicutes that may include anaerobic bacteria inhibited under aerobic conditions in the AT group.
