Journal ArticleDOI
A review on the application of different treatment processes for emulsified oily wastewater
TL;DR: In this article, an analytical insight on the merits of the process for the treatment of such emulsified system has been provided, and different microorganisms that are required for bioremediation of either oil spill over a large aquatic zone or oil-water emulsion at source point.
Journal ArticleDOI
A Comparative Study on the Production of Galacto-oligosaccharide from Whey Permeate in Recycle Membrane Reactor and in Enzymatic Batch Reactor
TL;DR: In recycle membrane reactor, GOS production was found to be 33% higher than that in the batch reactor, and monosaccharide concentration was 78% lower with 23% remaining enzyme activity after 18,000 s of reaction time.
Journal ArticleDOI
A review on the production of fermentable sugars from lignocellulosic biomass through conventional and enzymatic route—a comparison
TL;DR: Based on the biomass nature, the evaluated hot water pretreatment followed by enzymatic hydrolysis with a provision of enzyme reusability seems to be promising for enhanced biofuel-production.
Journal ArticleDOI
Feasibility study of enzyme immobilization on polymeric membrane: A case study with enzymatically galacto-oligosaccharides production from lactose
Dwaipayan Sen,Ankur Sarkar,Aaron Gosling,Sally L. Gras,Geoff W. Stevens,Sandra E. Kentish,Prashant K. Bhattacharya,Andrew R. Barber,Chiranjib Bhattacharjee +8 more
TL;DR: In this article, an exhaustive investigation on the effect of β-galactosidase (EC 3.2.23) immobilization on polymeric polyether sulfone, cellulose triacetate and thin film composite polyamide membrane to produce galacto-oligosaccharides from lactose is presented.
Journal ArticleDOI
