From: Bacterial and archaeal communities in Lake Nyos (Cameroon, Central Africa)
Denaturing gradient gel electrophoresis (DGGE) profiles of bacterial communities at different depths in Lake Nyos (a). Dendrogram calculated with the clustering algorithm of Unweighted Pair-Group Method with an Arithmetic Mean (UPGMA) for bacteria in samples from all depths (b). Vertical changes of Shannon-Weaver index of diversity (H’) based on the number and relative intensities of the bands for bacteria identified by DGGE analysis of PCR-amplified 16S rRNA gene (c). NSed: Sediment sample collected at the bottom of the lake. Arabic numerals: Successfully sequenced bands for bacteria. M: Mass ladder standards.
