Bacterial luciferase catalyzes the reaction of FMNH2, O2, and an aliphatic aldehyde to yield the carboxylic acid, FMN, water and blue-green light. The kinetics of the bacterial luciferase reaction were measured by stopped-flow spectrophotometry at pH 7 and 25 degrees C for the series of aldehydes from n-heptanal to n-undecanal. The rate of formation of the 4a-hydroperoxyflavin intermediate was ...

Nano-graphene oxide was synthesized by the oxidation of graphite powders. The structural nature of the nano-graphene oxide was characterized by a variety of techniques including XRD, TEM, FT-IR and UV/Vis. The functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. The catalytic activity of nano-graphene oxide was investigated on Crossed-...

Pyrano [2,3-d] pyrimidinone derivatives have received considerable interest from the pharmaceutical industry due to their wide range of interesting biological and therapeutic properties. Nano Al2O3 was found to be a highly efficient solid acid catalyst for the preparation of pyrano [2,3-d] pyrimidinone derivatives from the reaction of barbituric acid, aryl aldehyde and mal...

Controlling the flow properties of aqueous formulations is essential in fields as diverse biotechnology, cosmetics, paints, or chemically enhanced oil recovery, to cite a few. This work presents study association, solutions, complementary polyacrylamides carrying amino and aryl aldehyde side-groups. Through free radical polymerization, copolymers with tunable molar masses (Mn ranging from 60 37...

Heavy metal contamination still prevails due to improper discharge of effluents from industries, mining activities, agricultural and domestic sources. Hence, the objectives this study were isolate bacteria fungi with high potentials for biosorption Cd(II), Pb(II), Cr(III) Ni(II) explore their functional groups. Bacteria able grow in presence 0.1% selected heavy metals isolated enumerated using ...

Abstract: Background: From the wide range of previous literature studies indicated that thiazolidinedione’s reacts with substituted benzaldehydes undergoes knoevenagel condensation gives respective arylidene derivatives. In our attempt all titled compounds were designed and developed by replacement furan- 2-aldehyde, so furan moiety was introduced in molecule. Materials Methods: 5-[(furan-2-yl)...

Aldehyde assisted fractionation of biomass produces an acetal-stabilised lignin that is fully upgradeable. We exploit the aldehyde to control lignin's physical properties, producing lignins can be soluble in both polar and apolar solvents.
