  1. aData source: IMG/M [18]; btotal number of GHase matches in each metagenome are given; translated sequences from all 43 environmental metagenome projects were blast-searched against the CAZy sequences for homologues of glycosyl hydrolases using an e value < 10-40 as a cut-off threshold; cthe five most abundant glycosyl hydrolase families are listed. GHX is short for glycosyl hydrolase family X; percentages of each glycosyl hydrolase family are indicated inside parentheses.
