Bacillus coagulans
Bacillus coagulans is a type of microbe. It is utilized correspondingly to lactobacillus and different probiotics as “valuable” bacteria. People take Bacillus coagulans for looseness of the bowels, including irresistible sorts, for example, rotaviral, voyager’s, and the runs brought about by anti-microbials. Bacillus coagulans is likewise utilized for general assimilation ...

Investigation of equilibrium and kinetics of Cr(VI) adsorption by dried Bacillus cereus using response surface methodology
In this study, response surface methodology (RSM) based on three-variable-five-level central composite rotatable design was used to analyze the effects of combined and individual operating parameters (biomass dose, initial concentration of Cr(VI) and pH) on the Cr(VI) adsorption capacity of dried Bacillus cereus. A quadratic polynomial equation was obtained to predict the adsorbed Cr(VI) ...

Preparation of a novel positively charged nanofiltration composite membrane incorporated with silver nanoparticles for pharmaceuticals and personal care product rejection and antibacterial properties
A novel positively charged N-[(2-hydroxy-3-trimethylammonium)propyl] chloride chitosan (HTCC)-Ag/polyethersulfone (PES) composite nanofiltration membrane was easily prepared by coating the active layer, HTCC, onto PES as the support through epichlorohydrin as the cross-linking reagent and nano-Ag particles as the introduced inorganic components. Scanning election microscopy, X-ray ...

Study on the adsorption of bacteria in ceramsite and their synergetic effect on adsorption of heavy metals
In this paper, heavy metal adsorption by ceramsite with or without Bacillus subtilis (B. subtilis) immobilization was studied, and the synergetic effect of ceramsite and bacteria was discussed in detail. To investigate the roles of the micro-pore structure of ceramsite and bacteria in removing heavy metals, the amount of bacteria immobilized on the ceramsite was determined and the effect of pH ...

Microbiologically influenced corrosion in dairy effluent
Abstract: In the dairy industry mild steel is used as the construction material for the effluent treatment plants, pipelines, reinforcement in concrete structures etc. The steel exposed to the dairy effluent faces corrosion due to the microbes. In the present study the role of microbes in dairy effluent on the corrosion of mild steel has been investigated. Pseudomonas sp., Streptococcus sp., ...

Isolation and identification of the sulphate-reducing bacteria strain H1 and its function for hydrolysed polyacrylamide degradation
The sulphate-reducing bacteria strain H1 with the function for Hydrolysed Polyacrylamide (HPAM) degradation was isolated from a curing pot in the HPAM distribution station of Daqing Oil Field using the Hungate Anaerobic Technique. The isolates were characterised morphologically, physiologically, biochemically and molecularly. The pictures of the Atomic Force Microscope (AFM) have shown that this ...

Bio-enhanced activated carbon filter with immobilized microorganisms for removing organic pollutants in the Songhua River
Five dominant microorganisms including four kinds of Pseudomonas and one kind of Bacillus were isolated from the Songhua River. The organic pollutants removal potential and community composition of these five dominant microorganisms immobilized on activated carbon filter, which is called the bio-enhanced activated carbon filter (BEAC), were investigated to compare with the naturally formed ...

Production of an insecticidal crystal protein from bacillus thuringiensis by the methylotroph methylobacterium extorquens
The Cry1Aa protein from Bacillus thuringiensis is an insecticidal protein that is highly active against several species of Lepidoptera. We cloned and expressed the cry1Aa gene in a plant-colonizing methylotroph, Methylobacterium extorquens, under the control of the strong M. extorquens AM1 methanol dehydrogenase promoter, PmxaF. Transmission electron microscopy revealed characteristic bipyramidal ...

Efficiency of peracetic acid in inactivating bacteria, viruses, and spores in water determined with ATP bioluminescence, quantitative PCR, and culture-based methods
The disinfection efficiency of peracetic acid (PAA) was investigated on three microbial types using three different methods (filtration-based ATP (adenosine-triphosphate) bioluminescence, quantitative polymerase chain reaction (qPCR), culture-based method). Fecal indicator bacteria (Enterococcus faecium), virus indicator (male-specific (F+) coliphages (coliphages)), and protozoa ...

Are Probiotics The Future Of Cleaning?
Given the choice between a cleaner that reduces germs by 86% and one that all but eliminates them at 99.9%, which one would you choose? If you’re like most people, the answer appears simple – get rid of as many germs as possible. But those nearly 100% effective cleaners aren’t necessarily the best choice. Why? Because they kill all germs, good and bad. Probiotics are friendly ...

The combined effects of carbon/nitrogen ratio, suspended biomass, hydraulic retention time and dissolved oxygen on nutrient removal in a laboratory-scale anaerobic–anoxic–oxic activated sludge biofilm reactor
The current trend in sustainable development deals mainly with environmental management. There is a need for economically affordable, advanced treatment methods for the proper treatment and management of domestic wastewater containing excess nutrients (such as nitrogen and phosphorus) which can cause eutrophication. The reduction of the excess nutrient content of wastewater by appropriate ...
