Microbial biomass and activity in lead-contaminated soil

Article Abstract:

Microbial community diversity, metal resistance and potential microbial activity are analyzed in three soil samples with lead contents ranging from 0.00039 to 48 mmol of Pb kg of soil (super -1). It is shown that biomass concentrations are directly related to lead content. Each of the three soils contains active microbial populations that mineralize ((super 14)C) glucose. In addition, community in the soil with the highest lead content is not related to the communities in the other soils.

Seasonal variations in microbial populations and environmental conditions in an extreme acid mine drainage environment

Article Abstract:

The type and amount of bacteria in acid mine drainage sites depends on pH, temperature, conductivity, and rainfall. This was the conclusion of a study at Iron Mountain, California, which is located in the West Shasta Mining district near Redding, California.

How stable is stable? Function versus community composition

Article Abstract:

Bacterial communities can maintain a stable ecosystem even though the species present may change over a period of time. This was the conclusion of researchers who analyzed progression in a community of methanogens in a laboratory reactor.
