Kinetics and Production of Rhamnolipid from in Shake-Flask and Fabricated Batch Reactor.

Unlabelled: Rhamnolipid producing was selected for this investigation to optimize the metabolite production in fabricated batch reactor after studying yield kinetics in shake-flask and tried to reduce the overall production cost through recovery technology. Using various kinetic models, maximum specific growth rate (μ) and half velocity constant (K) of were determined to be 0.185 ± 0.

Characterization of sp. TMB2 produced rhamnolipids for ex-situ microbial enhanced oil recovery.

The present study describes the ex-situ production of a biosurfactant by sp. TMB2 for its potential application in enhancing oil recovery. The physicochemical parameters such as temperature and pH were optimized as 30 °C and 7.

Chitosan coated silk fibroin surface modified by atmospheric dielectric-barrier discharge (DBD) plasma: a mechanically robust drug release system.

The current study is designed to develop mechanically strong chitosan (Cs) coated silk based drug delivery system loaded with amoxicillin trihydrate (AMOX). For this purpose, surface modification of silk fibroin (AASF) yarn is carried out using dielectric barrier discharge (DBD) oxygen (O) plasma at atmospheric pressure followed by coating with drug incorporated Cs (AASF/O/Cs-AMOX). It is observed that O plasma treatment results in altering surface chemistry and morphology of silk fibroin surface which subsequently improves mechanical properties of AASF/O/Cs-AMOX yarn.

Optimization and characterization of a glycolipid produced by Achromobacter sp. to use in petroleum industries.

A biosurfactant, produced by Achromobacter sp. TMB1 is reported through this investigation having physiochemical properties useful for operational and remedial activities in petroleum industries. The strain isolated from soils of local petrol pumps when allowed to grow in glucose containing mineral salts media (MSM) in ambient environment that is, 30 °C and varying pH in between 5.

Sonication assisted assemblage of exotic polymer supported nanostructured bio-hybrid system and prospective application.

This work was focused on sonication mediated immobilization of porcine pancreatic lipase (PPL) onto poly(ethylene glycol) supported silver-iron oxide hybrid nanoparticles (PEG-Ag/IONPs). Selected process parameters of sonication were optimized using response surface methodology. Sonication assisted assemblage of spherical PEG-Ag/IONPs and consequent evolution of nanorods post PPL immobilization were documented.
