Crude hydrolytic extracellular enzymes (CHEEs) generated by a mixed culture of microorganisms during fermentation have high potential as economically feasible biocatalysts for the hydrolysis complex organic wastes. This study investigates feasibility CHEEs substitutes commercial based on series anaerobic batch tests CH4 production fed pretreated waste activated sludge (WAS). The results showed ...

MACROPHAGES ARE ASSOCIATED WITH MOST CHRONIC INFLAMMATORY LESIONS, AND THESE CELLS CONTAIN ENZYMES THAT ARE ABLE TO DESTROY CONNECTIVE TISSUE CONSTITUENTS. Normal lymphoid cells responding to a mitogen, phytohemagglutinin-P, release factor(s) that cause a marked increase in the size and enzyme content for mononuclear phagocytes maintained in culture. The stimulated macrophages, which by several...

The aim of this work was to study the enzymatic activities hydrolases in blood serum patients with bacterial pneumonia, pneumonia caused by SARS-CoV-2 and practically healthy volunteers who made up comparison group. A number enzymes related innate immunity were determined: lysozyme, elastase, BAPNAamidase deoxyribonuclease activity. Results: it shown that has highest level elastase lysozyme act...

Microbial extracellular hydrolytic enzymes that degrade organic matter in aquatic ecosystems play key roles in the biogeochemical carbon cycle. To provide linkages between hydrolytic enzyme activities and genomic or metabolomic studies in aquatic environments, reliable measurements are required for many samples at one time. Extracellular proteases are one of the most important classes of enzyme...
