To generate polyethersulfone membranes with a biocatalytically active surface, pancreatin was covalently immobilized. Pancreatin is a mixture of digestive enzymes such as protease, lipase, and amylase. The resulting membranes exhibit self-cleaning properties after “switching on” the respective enzyme by adjusting pH and temperature. Thus, the membrane surface can actively degrade a fouling laye...

To obtain high efficiency from animals, it is necessary to maximize the ability benefit feed, as well protect animal health. One of important applications in this direction feed additives. Feed additives are plant and products microorganisms that increase fish production welfare, improve digestion digestive system microflora contribute preservation nutrients feed. Although tissues used enzyme p...

Lactoperoxidase (LPO E.C. 1.11.1.7) is a member of the peroxidase family and an important glycoprotein containing heme group in its structure showing antimicrobial effect on disease causing microorganisms digestive system newborn babies. Thiazoles are simplest members heterocyclic compounds nitrogen sulfur atoms their structure. Many active pharmaceutical substances such as vitamin B1, penicill...

  Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...

This paper analyses the antioxidant enzymes response of Mytilus galloprovincialis exposed to a tar mixture during laboratory assay. These mixtures are generally used in cleaning and waterproofing wooden rafts mussel culture, characterized by their high content PAHs transition metals. The punctual spillage these around could cause stress, affecting culture sustainability product quality for huma...
