the vigna subterranean (l.) verdc hull’s (vsvh) potential to remove cr(vi) ions from aqueous solutions was investigated. the biosorbent was characterised by ftir, sem-edx and xrf before and after exposure to cr(vi). the surface comprised of phenolic, carboxylate, sulphonate, carboxyl, ammines, silica, silanol, phosphite esters, alkyl and hydroxyl functional groups responsible for cr(vi) removal...

Biomass utilization for bio-energy, bio-fuels or bio-based products requires reduction of the material size within specific ranges depending on feedstock specie, handling and further processing / conversion processes. Biomass size reduction is a mechanical treatment process that refers to either cutting or comminuting processes that significantly change the particles size, shape and bulk densit...

This research investigated the application of Bio-Amp, a commercial bio-additive for the treatment of fat, oil, and grease (FOG) in a grease trap, and evaluated potential impacts of treated effluent on downstream collection system and treatment processes. Results show that after Bio-Amp treatment, FOG deposit formation was reduced by 40%, implicating a potential reduction of sewer line blockage...

Palladized biomass of Desulfovibrio vulgaris (Bio-Pd(0)) reduced Cr(VI) to Cr(III) at an initial rate four-fold higher than chemically-prepared Pd(0) metal. Optimal Cr(VI) reduction by suspended BioPd(0) occurred at pH 3, whereas pH did not affect the rate of Cr(VI) reduction by Bio-Pd(0) immobilized in agar beads. The rate of Cr(VI) reduction was concentration-dependent below 300 μmol dm−3, an...

The bio-stimulation technique offers a potentially useful and practical way for reproductive performance in rams. Reports on how bio-stimulation affects sexual potency rams are scarce: Knowledge of how rams respond to bio-stimulation is useful for persons who involved in semen collection; "hand" (controlled) mating, and the administration of sexual performance evaluations. The reduction of the ...

The amethyst BioBelt was used by 12 subjects for 1 hour three times per week along with the amethyst Bio-Mat during sleep, daily over a 3-month period. The author used two different biofeedback devices to measure pain reduction, body mass index (BMI) to measure fat reduction, and blood cortisol levels to measure stress reduction. The BioBelt and the far infrared, negative ion amethyst Bio-Mat r...

in this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. in this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were reduced to their corresponding reduce...
