Sulfate Reducing Bacteria (SRB) are a diverse heterogeneous group of anaerobic microorganisms inhabiting in various environmental conditions. SRB are one of the most important groups of microorganisms that participate in various nutritional cycles of the environment and cause degradation of various organic matters through the process of dissimilatory sulfate reduction. They are known to be impl...

The proteins associated with various membrane fractions, including smooth and rough endoplasmic reticulum, plasma membrane, and mitochondria of rat liver, were solubilized with sodium lauryl sulfate and separated by electrophoresis on sodium lauryl sulfate acrylamide gels. Smooth and rough endoplasmic reticulum have similar electrophoretic patterns. All other fractions have characteristic patte...

The complement system is a potent effector of innate immunity. To elucidate the pathophysiological role of the complement system in inflammatory bowel disease, we evaluated the effects of anti-C5 antibodies on the development of dextran sulfate sodium-induced colitis in mice. Dextran sulfate sodium-colitis was induced in BALB/c mice with intraperitoneal administrations of anti-C5 antibodies (1 ...

BACKGROUND We studied the annual variability of the concentration and isotopic composition of main sulfur species and sulfide oxidation intermediates in the water column of monomictic fresh-water Lake Kinneret. Sulfate concentrations in the lake are <1 mM and similar to concentrations that are proposed to have existed in the Paleoproterozoic ocean. The main goal of this research was to explore ...

A new kind of flocculants, named Polymer Silicate Phosphate Ferric Sulfate(PSPFS), was synthesized by ferrous sulfate used as the main material and activated silicic acid as additive. In this paper, High-Viscosity Oil Refining wastewater from Liaohe Petrochemical Corporation was the treatment object. Overall, the influencing factors and synthesis technology conditions of PSPFS were determined b...

The metabolism of Desulphovibrio desulphuricans does not appear to have been studied extensively. Stephenson and Stickland (1931) and Sisler and ZoBell (1950) showed that the organism can use gaseous hydrogen as a reducing agent for sulfate reduction. By growing cultures for several generations in mineral salt solution containing less than one part per million of sulfate, Sisler and ZoBell (195...

Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by transmission. Consensus to determine MPs in is lacking and, so, three digestion treatments were evaluated: Alkaline (potassium hydroxide) enzymatic (protease plus lipase) digestions, both combined with a hydrogen peroxide stage; an oxidative method using surfact...

To evaluate the efficacy of bioimmobilization of Cr(VI) in groundwater at the Department of Energy Hanford site, we conducted a series of microcosm experiments using a range of commercial electron donors with varying degrees of lactate polymerization (polylactate). These experiments were conducted using Hanford Formation sediments (coarse sand and gravel) immersed in Hanford groundwater, which ...
