Here, we report on the spatial and temporal variation in sulphate-reducing bacterial community structure and activity in three hypersaline coastal pans. Community structure was determined using denaturing gradient gel electrophoresis (DGGE). Cluster analysis of DGGE patterns indicated that similar microbial populations were generally found in individual pans but varied from one pan to the other...

ferula communis l., subsp. communis, namely giant fennel, has extensively been used in traditional medicine for a wide range of ailments. fresh plant materials, crude extracts and isolated components of f. communis showed a wide spectrum of in vitro and in vivo pharmacological properties including antidiabetic, antimicrobial, antiproliferative, and cytotoxic activities. the present paper, revie...

This study reports the effects of long-term elevated atmospheric CO2 on root production and microbial activity, biomass, and diversity in a chaparral ecosystem in southern California. The free air CO2 enrichment (FACE) ring was located in a stand dominated by the woody shrub Adenostoma fasciculatum. Between 1995 and 2003, the FACE ring maintained an average daytime atmospheric CO2 concentration...

Field experiments are described involving nitrogen fertilizer in wheat field to research its effect on microbial quantity and enzyme activity. The results showed that 250 kg N hm applied in wheat field (1) can increase bacteria, fungi, actinomycetes quantity by 39.9%, 56.7% and 70.5% compare to 0 kg N hm. (2) Similarly, the activities of soil urease, catalase and FDA expressed 60.8%, 18.3% and ...

Effects of elevated CO(2) on soil microorganisms are known to be mediated by various interactions with plants, for which such effects are relatively poorly documented. In this review, we summarize and synthesize results from studies assessing impacts of elevated CO(2) on soil ecosystems, focusing primarily on plants and a variety the of microbial processes. The processes considered include chan...

Microbial communities are in close contact with the wetland soil microenvironment and can therefore function effectively as monitors of soil pollution. The objective of this studywas to determine changes in the functional responses of microbial communities as a result of an external input of nutrients, while controlling for vegetation. A controlled experiment was performed at the mesocosm scale...

Energy shortage and environmental pollution Microorganisms in the anode chamber oxidize fuel have caused global disasters. Thus, active research to (electron donor e.g. glucose, acetate, etc.) to produce find out alternate sources of energy especially renewable electrons and protons. Produced electrons are transferred sources of energy is a new trend [1]. In recent years, to cathode compartment...
