In field trapping tests in Hungary cinnamyl alcohol (3-phenyl-2-propen-l-ol) and transanethole [(1-methoxy-4-(1-propenyl)benzene)] attracted significantly more adult Epicometis (Tropinota) hirta (Coleoptera, Scarabaeidae, Cetoniinae) when presented together in the same bait compared to the single compounds Best attraction was recorded by a 1:1 mixture. Addition of other common floral scent comp...

Quantitative image analysis (QIA) is a simple and automated tool for process monitoring that, when combined with chemometric techniques, enables the association of changes in microbiota morphology to various operational parameters. To that effect, principal component analysis, multilinear regression, ordinary least squares methods were applied obtained dataset biotransformation conditions Y. li...

A method for determining lipase enantioselectivity in the transacylation of sec-alcohols in organic solvent was developed. The method was applied to a model library of Candida antarctica lipase A (CalA) variants for improved enantioselectivity (E values) in the kinetic resolution of 1-phenylethanol in isooctane. A focused combinatorial gene library simultaneously targeting seven positions in th...

Kinetic resolution of racemates with lipases is the preferred method for producing bioactive compounds. One strategy obtaining highly enantioselective that are stable in organic media often used these reactions to improve existing by protein engineering. In this work, we engineered lipase LipC12, which has good stability media, but only moderate enantioselectivity. Molecular docking LipC12 iden...

Initial reactions in anaerobic oxidation of ethylbenzene were investigated in a denitrifying bacterium, strain EB1. Cells of strain EB1 mineralized ethylbenzene to CO2 under denitrifying conditions, as demonstrated by conversion of 69% of [14C]ethylbenzene to 14CO2. In anaerobic suspensions of strain EB1 cells metabolizing ethylbenzene, the transient formation and consumption of 1-phenylethanol...

It has been shown that ruthenium polypyridyl aqua complexes have basically the same electrochemical behavior in weakly coordinating organic solvents, such as methylene chloride and acetone, water. Therefore, their use electrocatalytic processes water, they conducted an ecologically cleaner system, can bring significant benefits for mankind, well nature economy. In this sense, new complex contai...
