中文摘要 | To find out different sampling approaches how to affect DNA fingerprinting, environmental genomic DNA was prepared with three sampling approaches. The DNA profiles of 5 bacterial subgroups (alpha-,beta-,gamma-Proteobacteria, Bacteroidetes and Cyanobacteria) and total bacteria were investigated by using denaturing gradient gel electrophoresis (DGGE) fingerprinting. The DGGE patterns showed alpha-Proteobacteria had more free-living OTUs, while gamma-Proteobacteria and Bacteroidetes had more particle-attached OTUs. Cyanobacteria and beta-Proteobacteria had approximately equal OTU number in the two fractions. Principle component analysis based on DNA banding patterns showed there were obvious differences among free-living, particle-attached fraction and whole bacterial community composition of 3 bacterial subgroups (alpha-, gamma-Proteobacteria and Bacteroidetes) and total bacteria, while the patterns of beta-Proteobacteria and Cyanobacteria were similar, suggesting the dynamics of bacterial subgroups can be better understand by combining different collection approaches. |
