Genetic diversity of cyanobacterial communities in Lake Kinneret (Israel) using 16S rRNA gene, psbA and ntcA sequence analyses

Abstract: The genetic diversity of cyanobacterial communities was studied at various depths in Lake Kinneret (Israel). Denaturing gradient gel electrophoresis (DGGE) of specific 16S rRNA gene PCR products showed significant differences in the cyanobacterial community structure between epi-and hypolimnetic waters. Sequences of clone libraries prepared from 16S rRNA gene PCR products from epi-and hypolimnion revealed the presence of at least 11 different groups of cyanobacteria. Clones related to the unicellular cyanobact… Show more

“…Since the isolation of Cyanobacteria from environmental samples is not always successful, cultureindependent identification of cyanobacteria is more promising in describing community structure. Molecular technologies based on 16S rRNA gene amplification are already widely employed for the analysis of natural samples (Eiler and Bertilsson 2004;Zwart et al 2005;Junier et al 2007). …”

“…Different environmental conditions leave long-term geochemical signal records in the sediment such as elemental isotopes and compositions of organic matter, which can be used to interpret paleoecological and paleoenvironmental histories (Bernasconi et al, 1998;Meyers, 2003;Routh et al, 2004;Jinglu et al, 2007). Microbial communities play a key role in the transformation of complex organic matter and biochemical cycling of the primary elements in freshwater lake sediments (Nealson, 1997;Glissmann et al, 2004;Junier et al, 2007;Kondo & Butani, 2007). The change of environmental factors, such as salinity (Edlund et al, 2006), organic matter and nutrients (Nelson et al, 2007), can influence the microbial community structure in the sediment environments.…”
