This study was focused on the polyhydroxybutyrate (PHB) accumulation property of Bacillus aryabhattai isolated from environment. Twenty-four polyhydroxyalkanoate (PHA) producers were screened out from sixty-two environmental bacterial isolates based on Sudan Black B colony staining. Based on their PHA accumulation property, six promising isolates were further screened out. The most productive i...

The oxidative degradation of Procion Red MX-5B by solar Fenton’s has been investigated using sunlight as irradiation source in presence of hydrogen peroxide and Fe2+. Maximum decolorization (99%) and COD removal (97%) for MX-5B was obtained at H2O2 dose of 16.6 mM and at 30 min irradiation time. Fe2+ dose of 0.36 mM was optimum for Procion Red MX-5B degradation. The solar degradation mechanism ...

bacteria make up about half of the living organisms inside of the rumen. however, they do more than half of the work in the rumen. the bacteria work together. some breakdown certain carbohydrates and proteins which are then used by others. some require certain growth factors, such as b-vitamins, which are made by others. some bacteria help to clean up the rumen of others’ end products, such as ...

extracellular polymeric substances are defined as high molecular weight compounds secreted by the microorganisms in the surrounding area. since these extracellular substances are mainly polysaccharide, they are named exopolysaccharide. microbial exopolysaccharides composed of sugar residue have growing interest as a new class of microbial products which can be used in food, pharmaceutical, and ...
