The potential to stimulate an indigenous microbial community to reduce a mixture of U(VI) and Tc(VII) in the presence of high (120 mM) initial NO3- co-contamination was evaluated in a shallow unconfined aquifer using a series of single-well, push-pull tests. In the absence of added electron donor, NO3-, Tc(VII), and U(VI) reduction was not detectable. However, in the presence of added ethanol, ...
microbial activity and spoilage of chicken meat from the market in mashhad, iran, stored in air at 0, 4, 10 and 15°c was assessed. microbial spoilage population, total volatilebase nitrogen (tvb-n), ph and organoleptic changes were determined. based on the results of sensory analysis, shelf-life of chicken meat stored at 0, 4, 10 and 15°c was 72, 120, 220 and 320 h, respectively. tvb-n that ser...
UNLABELLED Sulfur is an important element in sustaining microbial communities present in hydrothermal vents. Sulfur oxidation has been extensively studied due to its importance in chemosynthetic pathways in hydrothermal fields; however, less is known about sulfate reduction. Here, the metagenomes of hydrothermal chimneys located on the ultraslow-spreading Southwest Indian Ridge (SWIR) were pyro...
