Poor lipid degradation limits low-temperature anaerobic treatment of domestic wastewater even when psychrophiles are used. We combined metagenomics and metaproteomics to find lipolytic bacteria and their potential, and actual, cold-adapted extracellular lipases in anaerobic membrane bioreactors treating domestic wastewater at 4 and 15 °C. Of...

Acylated Morita-Baylis-Hillman (MBH) adducts were synthesised and subjected to enzymatic kinetic resolution (EKR) by hydrolysis employing various lipase enzymes: from P. fluorescens, P. cepacia (PCL), C. antarctica A (CAL−A), C. antarctica B (CAL−B) and Novozyme 435. In a number of instances enantiopure Morita-Baylis-Hillman acetates or...

The question of how to distinguish between lipases and esterases is about as old as the definition of the subclassification is. Many different criteria have been proposed to this end, all indicative but not decisive. Here, the activity of lipases in dry organic solvents as a criterion is probed on a minimal α/β hydrolase fold enzyme, the...

Enantiopure β-amino alcohols constitute one of the most significant building blocks for the synthesis of active pharmaceutical ingredients. Despite the availability of a range of chiral β-amino alcohols from a chiral pool, there is a growing demand for new enantioselective synthetic routes to vicinal amino alcohols and their derivatives. In...

Poor H <sub>2</sub> O <sub>2</sub> -resistance by enzymes is a key bottleneck in the epoxidation process of oil by enzymatic methods. In this study, the stability of three lipases, from Aspergillus oryzae lipase (AOL), Aspergillus fumigatus lipase B (AflB), and marine Janibacter (MAJ1), in the presence of H <sub>2</sub> O <sub>2</sub> was...

The use of natural deep eutectic solvents (NADES) as multifunctional solvents for limonene bioprocessing was reported. NADES were used for the extraction of limonene from orange peel wastes, as solvent for the chemoenzymatic epoxidation of limonene, and as sacrificial electron donor for the in situ generation of H <sub>2</sub> O <sub>2</sub>...

H <sub>2</sub> O <sub>2</sub> , is an attractive oxidant for synthetic chemistry, especially if activated as percarboxylic acid. H <sub>2</sub> O <sub>2</sub> , however, is also a potent inactivator of enzymes. Protein engineering efforts to improve enzyme resistance against H <sub>2</sub> O <sub>2</sub> in the past have mostly focused on...

A concurrent bienzymatic cascade for the synthesis of optically pure (S)-4-methoxymandelonitrile benzoate ((S)-3) starting from 4-anisaldehyde (1) has been developed. The cascade involves an enantioselective Manihot esculenta hydroxynitrile lyase-catalyzed hydrocyanation of 1, and the subsequent benzoylation of the resulting cyanohydrin (S)-2...

?-Hydroxy carbonyl compounds are an important class of compounds often found as a common structural motif in natural products. Although the molecules themselves look rather simple, their synthesis can be challenging. Water addition to conjugated C = C bonds opens up a straightforward route for the preparation of ?-hydroxy carbonyl compounds....

Proteins are biological macromolecules, which are among the key components of all living organisms. Proteins are nowadays present in all fields of biotech industry, such as food and feed, synthetic and pharmaceutical industry. They are isolated from their natural sources or produced in different cell lines. Most important large-scale...

The key to obtaining an optimum performance of an enzyme is often a question of devising an effective method for its immobilization. In the present review, we describe a novel, versatile and effective methodology for enzyme immobilization as CLEAs (cross-linked enzyme aggregates). The method is exquisitely simple (involving precipitation of the...
