Microscale and molecular assessment of impacts of nickel, nutrients, and oxygen level on structure and function of river biofilm communities

The study was conducted to assess the impact of nutrients, dissolved oxygen (DO) concentration and nickel on the formation of river biofilm, its structure, its role and the composition of the community. However, the outcome indicated that the groups were a part of the bacteria developing either from the freshwater and marine environments or from the agricultural soils or from the waste matter of the industries.
