*Top BLAST hit indicates the closest reference species that matched the environmental strains using BLAST search (http://blast.ncbi.nlm.nih.gov/Blast.cgi). Maximum identity represents the percentage identity between the environmental strains and the closest reference species. The fifth column shows the isolated source of the closest reference species.
