Fig. 2From: Metagenome phylogenetic profiling of microbial community evolution in a tetrachloroethene-contaminated aquifer responding to enhanced reductive dechlorination protocolsColor shift in microbial samples. The tube on the left is the sample collected one month prior to application of remediation protocols, the tube on the right is the sample collected five months after the addition of EVO, nutrients, and hydrogen gas to the aquiferBack to article page
