Journal ArticleDOI
Biolubricant synthesis from waste cooking oil via enzymatic hydrolysis followed by chemical esterification
TL;DR: In this paper, a two-step process of C. rugosa lipase-mediated hydrolysis of WCO to free fatty acids (FFA) followed by Amberlyst 15H esterification of FFA with octanol was developed.
Journal ArticleDOI
Optimization of the production parameters of octyl ester biolubricant using Taguchi's design method and physico-chemical characterization of the product
TL;DR: In this paper, a statistical experimental design method (Taguchi L 9 orthogonal array) was implemented to optimize the experimental conditions to maximize conversion of free fatty acids (FFA) to the corresponding octyl esters.
Journal ArticleDOI
JNK pathway restricts DENV2, ZIKV and CHIKV infection by activating complement and apoptosis in mosquito salivary glands.

TL;DR: The broad antiviral function of JNK pathway in SGs is revealed and it is shown that it is mediated by a TEP20 complement and Dronc-induced apoptosis response, expanding the understanding of the immune arsenal that blocks arbovirus transmission.
Journal ArticleDOI
A kinetic study on the Novozyme 435-catalyzed esterification of free fatty acids with octanol to produce octyl esters
Avisha Chowdhury,Debarati Mitra +1 more
TL;DR: It was found that the esterificaton reaction followed the Ping‐pong bi‐bi kinetics with no inhibition by substrates or products within the studied concentration range, and the enzyme reusability data can further facilitate mass production by curtailing the cost of expensive enzyme consumption.
Equilibrium, Thermodynamic and Kinetic Studies for Removal of Copper (II) from Aqueous Solution by Onion and Garlic Skin
TL;DR: In this article, the removal of Cu2+ from aqueous solution by onion skin and garlic skin was studied as a function of various experimental parameters, including FTIR analysis and Boehm titration.
