Hydrogen gas (∼60% H2) was produced in a continuous flow bioreactor inoculated with heat-treated soil, and fed synthetic wastewater containing glucose (9.5 g l). The pH in the bioreactor was maintained at 5.5 to inhibit consumption of H2 by methanogens. The objective of this study was to characterize bacterial communities in the reactor operated under two different hydraulic retention times (HR...

AIMS To identify novel antibiotic-producing microbial strains with unprecedented pertinence. We hypothesize that site-specific soil samples will contain a variety of antibiotic-producing species (APS) with diverse specificity of molecular elements. PLACE AND DURATION OF STUDY Laboratory of Microbiology, Division of Biological and Health Sciences, University of Pittsburgh, Bradford, PA-16701, ...

The production and quality of Rehmannia glutinosa can be dramatically reduced by replant disease under consecutive monoculture. The root-associated microbiome, also known as the second genome of the plant, was investigated to understand its impact on plant health. Culture-dependent and culture-independent pyrosequencing analysis was applied to assess the shifts in soil bacterial communities in ...

While topography can infer erosion potential, the practice of conventional agronomic management trigger accelerated and pose major threats to soil assets such as biodiversity. The majority farmlands in Upper-Eastern Ghana are moderately hilly highly susceptible erosion. This study pioneered comparative interactive effects versus conservation agriculture practices (reduced tillage, main crop cov...

This is the Þrst report of sequence-speciÞc microsatellite markers (simple sequence repeats [SSRs]) of fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), an economically important pest of crops on theAmericas.We isolated 192microsatellitemarkers byusing pyrosequencing and screened 15 individuals from eight isofamilies collected from three geographical areas: Puerto Rico...

This research focuses on the potential for microbial treatment to stabilize compacted soils, which are often utilized in earthwork projects. A silt–clay sand was used describe a particular kind of soil. The suggested remedy makes use soil’s naturally occurring urea and Ca2+, as well microorganisms introduced compaction water. Two alternative initial water-content types were examined: those dry ...
