Atomistic molecular dynamics simulation and COSMO-SAC approach for enhanced 1,3-propanediol extraction with imidazolium-based ionic liquids.

Context: 1,3-Propanediol (1,3-PDO) is a key chemical in various industries, including pharmaceuticals and material sciences, and is projected to see significant market growth. However, the current challenges in its downstream processing, particularly in terms of cost and efficiency, highlight the need for innovative solutions. Our study delves into using ionic liquids (ILs) as a potential alternative, aiming to address these critical separation challenges more sustainably and efficiently.

Assessment of Rheological Behaviour of Water-in-Oil Emulsions Mediated by Glycolipid Biosurfactant Produced by Bacillus megaterium SPSW1001.

A screening programme using mineral salt medium supplemented with n-hexadecane resulted in isolating a Bacillus megaterium SPSW1001 which was capable of producing surface active molecules lowering culture medium surface tension to 27.43 ± 0.029 mN/m and interfacial tension to 0.

Insight into the kinetically and thermodynamically controlled biosynthesis of silver nanoparticles.

The mechanism of nanoparticles (NPs) synthesis is a crucial prerequisite for the engineering of desirable material properties and is elusive due to the difficulty of studying the synthesis path and also due to lack of published work. The present study moves beyond the current conventional study of characterisation of NPs synthesis. It focuses on study of classical kinetics of metal NP using silver as a model metal to perform the required experiments, it aimed at understanding the crystallisation process which is the major root for the synthesis of metal NP.

An insight to flux-balance analysis for biochemical networks.

Systems biology is one of the integrated ways to study biological systems and is more favourable than the earlier used approaches. It includes metabolic pathway analysis, modelling, and regulatory as well as signal transduction for getting insights into cellular behaviour. Among the various techniques of modelling, simulation, analysis of networks and pathways, flux-based analysis (FBA) has been recognised because of its extensibility as well as simplicity.

Resveratrol isomeric switching during bioreduction of gold nanoparticles: a gateway for cis-resveratrolArchita.

Resveratrol, a polyphenolic and biocompatible molecule, exhibits significant pharmacological effects but has poor bioavailability and metabolic stability. It appears in two isomeric forms trans-(E)-resveratrol (tRes) and cis-(Z)-resveratrol (cRes). Many pharmacological activities studied so far are of tRes and is the most stable, predominant, and natural form.

Assessment of the Wettability of Hydrophobic Solid Substrate by Biosurfactant Produced by Bacillus aryabhattai SPS1001.

Characterized biosurfactant produced by Bacillus aryabhattai SPS1001 isolated from crude oil contaminated soil of Haldia Oil Refinery, IOCL, West Bengal, India, was used to evaluate the surface energy and wettability of hydrophobic substrate by sessile drop method. Bacterial cell culture with cells removed was screened for biosurfactant production by drop collapse assay where drop diameter measured was 12.53 ± 0.

Synthesis of silver nanoparticles by and computational profiling of nitrate reductase enzyme involved in production.

Biogenic synthesis of silver nanoparticles using microorganisms has found interest recently since last decade because of their prospect to synthesize nanoparticles of various size, shape and morphology which are eco-friendly. Here, an eco-friendly method for production of silver nanoparticles from cultured from is explored. Along with the biosynthesis and conformity test, studies was done on NADPH dependent nitrate reductase enzymes from the view point of designing a rational enzymatic strategy for the synthesis.

Technical insight on the requirements for CO-saturated growth of microalgae in photobioreactors.

Microalgal cultures are usually sparged with CO-enriched air to preclude CO limitation during photoautotrophic growth. However, the CO vol% specifically required at operating conditions to meet the carbon requirement of algal cells in photobioreactor is never determined and 1-10% v/v CO-enriched air is arbitrarily used. A scheme is proposed and experimentally validated for Chlorella vulgaris that allows computing CO-saturated growth feasible at given CO vol% and volumetric O mass-transfer coefficient (k a).
