The object of research is the created bioactive sorbent based on biochar from corn waste for purification oil-contaminated natural environments. expediency using cobs as a matrix – carrier microorganisms-destructors petroleum hydrocarbons in production biosorbent has been substantiated. Biochar meets requirements oil sorbents environmental friendliness, resistance (6–8 g per 1 sorbent), manufac...

A nanostructured biocatalytic interface reversibly gating electrochemical reactions upon chemical signals processed by immobilized enzymes was architectured. The chemical signals were converted to local interfacial pH changes causing restructuring of the stimuli-responsive polymer and switching ON-OFF the electrochemical reaction.

in the present study, streptomyces gulbargensis and its mutant form, s.gulbargensis mu24, immobilized on polyurethane foam were investigated for the production of l-asparaginase using groundnut cake extract as medium. the medium with an initial ph of 8.5 was inoculated with free and immobilized cells separately and then subjected to fermentation by incubation at 40oc and shaking at 200 rev/min....

lipase from candida antarctica, fixed on macroporous acrylic resin, has been used for the intermediate production of mono- and diolein by hydrolysis of triolein. the effect of altering concentrations of triolein and glycerol and the function of the molecular sieve on the hydrolysis reaction of triolein were investigated. the highest hydrolysis yield was observed for the utmost concentration of ...

penicillin g acylase from e. coli ta1 was immobilized by cross-linked enzyme aggregates (clea), a new method for immobilization. this biocatalyst and commercial immobilized penicillin g acylase (pga-450) were used to study the effect of ph, temperature and substrate concentration on the synthesis of ampicillin from phenyl glycine methyl ester (pgme) and 6-aminopenicillanic acid (6-apa). compare...

This study presents a filter system for the removal of pathogenic microorganisms from potable water using silver nanoparticle-modified silica sand. While sand has potential applications in wastewater treatment, its effectiveness microbial filtration falls short. Thus, there is need an environmentally friendly enhancement method. The nanoparticles were synthesized Commelina maculata leaf extract...

Sulfamethoxazole (SMX) is a common antibiotic frequently detected in the environment. This study investigated enhanced substrate degradation using an immobilized biomass reactor. The rates increased batch reactor operation, owing to of microorganisms polyurethane foam (PUF). rate at 50 mg/L was 38.8±3.8 mg SMX/day, and achieved 406.6±42.2 dry biomass/g PUF under optimum conditions. Two SMX-degr...
