In relation to the development of environmentally-friendly processing technologies for continuously growing market plastics, enzymes play an important role as green and sustainable biocatalysts. The present study reports use heterogeneous immobilized biocatalysts in solvent-free systems synthesis aliphatic oligoesters with Mws monomer conversions up 1500 Da 74%, respectively. To improve accessi...

In recent years, the development and deployment of nano-immobilized lipases, as robust biocatalysts, has appeared a promising alternative for biodiesel production. There is significant hike in using nano-sized support matrices enzyme-based biotransformation bioprocesses with ever-increasing scientific awareness nanotechnological advancement. Several nano-scale materials include magnetic non-mag...

The immobilization of biocatalysts or other bioactive components often means their transformation from a soluble to an insoluble state by attaching them solid support material. Various types fibrous textiles both natural and synthetic sources have been studied as suitable material for immobilization. Strength, inexpensiveness, high surface area, porosity, pore size, availability in various form...

BACKGROUND Chlorophenols are environmental contaminants, which are highly toxic to living beings due to their carcinogenic, mutagenic and cytotoxic properties. Bacterial degradation has been considered a cost-effective and eco-friendly method of removing chlorophenols, compared to the traditional physical-chemical processes. RESULTS In this study, we first developed an efficient process for t...

The fermentation kinetics of penicillin production by Penicillium chrysogenum was carried out at 27°C and pH 6.0. Batch and repeated batch fermentations using agar-immobilized cells in fluidized bed bioreactor were studied for their potential application in production of penicillin from lactose, a fermentable sugar. Kinetics of immobilized cell fermentation, showed the penicillin yield of ~0.01...

In this paper we report a facile method for preparing co-immobilized enzyme and magnetic nanoparticles (MNPs) using metal coordinated hydrogel nanofibers. Candida rugosa lipase (CRL) was selected as guest protein. For good aqueous dispersity, low price and other unique properties, citric acid-modified magnetic iron oxide nanoparticles (CA-Fe₃O₄ NPs) have been widely used for immobilizing enzyme...

A bacterial strain capable of growing on propachlor (2-chloro-N-isopropylacetanilide) was isolated from soil by using enrichment and isolation techniques. The strain isolated, designated GCH1, was classified as a member of the genus Pseudomonas. Washed-cell suspensions of strain GCH1 accumulated N-isopropylacetanilide, acetanilide, acetamide, and catechol. Pseudomonas strain GCH1 grew on propac...
