Figure 4From: Microbial diversity and anaerobic hydrocarbon degradation potential in an oil-contaminated mangrove sedimentBacterial abundance at different depths of mangrove sediment. Abundance of bacterial populations on mangrove sediments of three different depths tested with q-PCR using oligonucleotide primers for 16S rRNA gene encoding fragment (a) and oligonucleotide primers for dsr gene (b). Bars with the same letter are not significantly different (one-way ANOVA).Back to article page
