report on biotechnological applications of proteolytic enzymes from lattices of euphorbian plants

چکیده
proteases catalyze the hydrolysis of peptide bonds in proteins. they are widely distributed in nature, nearly in all plants, animals and microorganisms. plant latex is a rich source of proteases. latex production is unique property of euphorbian plant, which could be a potential source of proteolytic enzymes. the highest proteolytic activity was observed in the latex of pedilanthus tithymaloides linn., which is followed by lattices of euphorbia tirucalli linn., euphorbia nivulia buch.-ham ., and euphorbia nerifolia linn. therefore, p. tithymaloides , e. tirucalli , e. nivulia , and e. nerifolia lattices were selected as potential sources of proteases. these proteases were effectively used to remove hair from goat skin indicating its potential in leather processing industry. these proteolytic enzymes showed potential environmental waste management applications such as degradation of chicken feather waste. additionally, the crude enzymes of the selected plants exhibited potent gelatinolytic activity almost correlated to release of silver from waste x–ray film. they also showed remarkable destaining property, indicating their importance in detergent industry. these enzymes have remarkable silk degumming property demonstrating their use in textile industries.

Enzymes: principles and biotechnological applications
Enzymes are biological catalysts (also known as biocatalysts) that speed up biochemical reactions in living organisms, and which can be extracted from cells and then used to catalyse a wide range of commercially important processes. This chapter covers the basic principles of enzymology, such as classification, structure, kinetics and inhibition, and also provides an overview of industrial appl...
متن کاملProteolytic enzymes from generative organs of flowering plants (Angiospermae).
Pollen proteases were discovered over 100 years ago, whereas the enzymes from female tissues have been used since the Roman era in simple biotechnological processes. In the last decade a great progress has been made in studies on plant proteases, including those from the generative organs. This paper reviews reports published in the last decade, concerning purification, properties and localizat...

15 صفحه اولBiotechnological Potential of Oxidative Enzymes from Actinobacteria
Oxidative enzymes are often considered for use in industrial processes because of the variety of reactions they are able to catalyse. In the past, most of these oxidative en‐ zymes were obtained from fungi. However, in recent years, it has become evident that these enzymes are also produced by bacteria, including actinobacterial strains, which can therefore be considered as an underexploited re...
