Comparison of the microbial community between original and improved biofilters. (a) Changes in microbial communities of the top 10 phyla that were significantly changed in the original biofilter. (b) Changes in microbial communities of the top 10 phyla that were significantly changed in the improved biofilter. (c) Changes in microbial communities of the top 10 genera that were significantly changed in the original biofilter. (d) Changes in microbial communities of the top 10 phyla that were significantly changed in the improved biofilter.
