The relationship between environmental variables and bacterial community of al-Kufa River sediments

الملخص EN

There is no any study about the sediment quality and bacterial composition in Al-Kufa River, so this study comes to investigation the correlation between the sediment quality and bacterial composition.

Four stations were chosen to sediments collection, for Jun, Aug (Summer 2011), Oct, and Dec (winter 2011).

Profiles of bacterial communities were generated using different culture media, and the results were interpreted with multivariate statistical analysis.

Findings suggested that microbial communities varied with sample collection sites and seasons.

The samples collected from the same sample sites at the same time had more similar microbial communities except the samples of station 3 and 4, which also had unique sediment quality.

Canonical correspondence analysis (CCA) revealed that the organic carbon concentration of the sediments accounted for a significant amount of the variability in the bacterial community composition.
