Abstract—Sediments munities in aquatic the transformation of major nutrient factors [4, 5, 8, 9, 10], play
environments are important because they are fundamental to key role in degradations anic pollutants in water column
biogeochemical and energy cycling, productivity as well as and sediments [6, 7]. They also function as “buffer zones” by
“buffering” capacity of aquatic ecosystems. We collected intercepting, stabilizing pollutants and excessive nutrients [11,
sediment samples from four stations characterized by different 12, 13, 14, 15]. Therefore, an understanding of a relationship
aquatic environmental conditions during two periods of times between sedimentary munities and
and investigated effects of nutrient factors on sedimentary environmental factors, . how nutrient factors affect
microbial biomass munity structures using phospholipid sedimentary munities and how the later acts on
fatty acid (PLFA) analysis. All four sampling sta
