Abstract

A study was conducted to assess the performance of various mixing regimes on methanogen biomass content in anaerobic digesters.  Methane production in anaerobic digesters is directly related to the methanogens within the system.  Current systems involve mixing to increase biogas production and system efficiency, however little is known about the underlying mechanisms of this relationship. …

Abstract

Soil microbial communities have been proposed as indicators of soil quality due to their importance as drivers of global biogeochemical cycles and their sensitivity to management and climatic conditions. Despite the importance of the soil microbiota to nutrient transformation and chemical cycling, physio-chemical properties rather than biological properties of soils are traditionally used as measures of environmental status.…
