Soil bacterial biomass, activity, phospholipid fatty acid pattern and pH tolerance in an area polluted with alkaline dust deposition

Article Abstract:

The utilization of the thymidine incorporation technique in describing the effect of increased biomass acidity, growth rate, phospholipid fatty acid pattern and acidity tolerance of the soil bacterial community is discussed. Bacterial counts, growth rate determinations and lipids extraction were conducted on a forest area polluted with alkaline dust from iron and steel works. The method was found to be effective in studying the acidity tolerance of the bacterial community in soils.

Rapid method of determining factors limiting bacterial growth in soil

Article Abstract:

Researchers have found that carbon, nitrogen, and phosphorus can be growth-limiting bacterial nutrients depending on the soil type and soil pH. Carbon is limiting in agricultural soil and forest humus soil, but the addition of straw shifted to nitrogen limitation. In high pH, limestone soils, phosphorus is the limiting nutrient.

Pathways for methanogenesis and diversity of methanogenic archaea in three boreal peatland ecosystems

Article Abstract:

The study aims to uncover the pathways used for methanogenesis in three different boreal peatland ecosystems and to describe the methanogenic populations involved. The results revealed that mesotrophic fen had the lowest proportion of CH4 produced from H2-CO2.
