the purpose of this study was to look for carbon materials for composting with rabbit manure. rabbit manure was composted with rice straw and mushroom residues. during the composting process, different related parameters were evaluated. results showed that the rabbit manure could be normally co-composted with rice straw or with mushroom residues. the gi value showed that both composts could hel...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...

microorganisms constitute more than half of the earth's biomass and in addition to quantity,they represent great diversity. in january 2013, the number of officially registered names forprokaryotic microorganisms at the genus and species levels were, respectively, approximately2100 and 12000. current authorized methods for classification and identification of newmicrobial taxa are polyphasic ap...

All biologists who sample natural communities are plagued with the problem of how well a sample reflects a community’s “true” diversity. New genetic techniques have revealed extensive microbial diversity that was previously undetected with culture-dependent methods and morphological identification (reviewed in references 2 and 46), but exhaustive inventories of microbial communities still remai...

Diversity is often associated with the functional stability of ecological communities from microbes to macroorganisms. Understanding how diversity responds to environmental perturbations and the consequences of this relationship for ecosystem function are thus central challenges in microbial ecology. Unimodal diversity-disturbance relationships, in which maximum diversity occurs at intermediate...

Mathematical models do not explicitly represent the influence of soil microbial diversity on soil organic carbon (SOC) dynamics despite recent evidence of relationships between them. The objective of the present study was to statistically investigate relationships between bacterial and fungal diversity indexes (richness, evenness, Shannon index, inverse Simpson index) and decomposition of diffe...

Diversity is the main descriptor of community structure and is a determining factor in the dynamics and function of ecological communities [1]. However, the latter implicitly differs based on the different types of organisms and their relative abundance within the community which is considered to be significant [2]. Research in microbial ecology focuses on the study of microbial community dynam...

The importance of microbial activity to ecosystem function in aquatic ecosystems is well established, but microbial diversity has been less frequently addressed. This review and synthesis of 100s of published studies on stream microbial diversity shows that factors known to drive ecosystem processes, such as nutrient availability, hydrology, metal contamination, contrasting land-use and tempera...

Soil microbial biomass is a key determinant of carbon dynamics in the soil. Several studies have shown that soil microbial biomass significantly increases with plant species diversity, but it remains unclear whether plant species diversity can also stabilize soil microbial biomass in a changing environment. This question is particularly relevant as many global environmental change (GEC) factors...
