Bacterioplankton Community Composition in Five Lakes Differing in Trophic Status and Humic Content

Bacterioplankton Community Composition in Five Lakes Differing in Trophic Status and Humic Content MICROBIAL ECOLOGY Microb Ecol (2000) 40:104–113 DOI: 10.1007/s002480000036 © 2000 Springer-Verlag New York Inc. Bacterioplankton Community Composition in Five Lakes Differing in Trophic Status and Humic Content E. S. Lindstro ¨m Department of Limnology, Evolutionary Biology Centre, Uppsala University, Norbyv. 20, SE-752 36 Uppsala, Sweden Received: 16 February 2000; Accepted: 27 April 2000; Online Publication: 18 July 2000 A BSTRACT To investigate the relation between lake type and bacterioplankton community composition, five Swedish lakes, which differed from each other in nutrient content and water color, were studied. Denaturing gradient gel electrophoresis (DGGE) of 16S rDNA was used to examine community composition. The DGGE-patterns of the different samples were analyzed in relation to physical, chemical, and biological data from the lakes by canonical correspondence analysis (CCA). The three variables found to most strongly correlate with the DGGE patterns were biomasses of micro- zooplankton, cryptophytes, and chrysophytes, suggesting that these biota had an impact on bacte- rioplankton community structure. Two of the three factors were, in turn, significantly correlated to parameters associated with the trophic status of the lakes, indicating that the nutrient content of the lakes, at least indirectly, influenced the structure of the bacterioplankton community.
