Family-level taxonomic analysis of metagenomic sequences obtained from ‘light’ and ‘heavy’ DNA samples from the SIP incubations using the STAMP software. Dark grey bars represent the ‘light’ DNA and light grey bars represent the ‘heavy’ DNA. Methylophilaceae family had the greatest proportional difference in the both ‘heavy’ metagenomes.
