Figure 4From: Anaerolineaceae and Methanosaeta turned to be the dominant microorganisms in alkanes-dependent methanogenic culture after long-term of incubationPhylogenetic tree of deduced amino acid sequences of alkylsuccinate synthetase genes (assA) genes from methanogenic alkanes-degrading enrichment culture (in red). Clone sequences with green were detected in the stage III by Wang et al. (2012). The topology of the tree was obtained by the maximum likelihood method. Bootstrap values (n = 1,000 replicates), values below 70% are not shown.Back to article page
