Modified PVA membrane for separation of micro-emulsion.

Release of liquefied hydrocarbons in domestic and industrial effluents, along with oil spills cause significant adverse effects on the soil, water, aquatic ecosystem, and humans. Thus, selective and cost-effective technology to address this challenge is highly desirable. Here, we report the fabrication of electrospun polyvinyl alcohol (PVA) membrane, modified with glutaraldehyde (GA) and a device thereof, for treatment of oil emulsions and recovery of precious fossil fuel.

Improved filtration for dye removal using keratin-polyamide blend nanofibrous membranes.

Dyes from industrial wastewaters represent one of the most hazardous pollutants as they are not effectively biodegradable. The present work is focused to study the novel properties of keratin-polyamide blend nanofibrous filtration membranes for treating wastewaters containing dye. Keratin protein was extracted from goat hair, a tannery waste through sulphitolysis process.

Mass cultivation of UV-B adapted Arthrospira platensis RRGK under open raceway pond for the production of Poly-β-hydroxy butyrate.

Six different strains of cyanobacteria were isolated from the freshwater lake, Arakkonam, India. Staining of cells with Nile Red showed the presence of large quantities of PHB granules in the cell cytoplasm of Arthrospira. Molecular identification of the strain was carried out using 16S rRNA analysis and their systematic position was ascertained as Arthrospira platensis RRGK.
