Every year the volume of production of poultry products all over the world is growing steadily. This contributes to a constant increase in the amount of by-products of poultry processing in the form of down and feather waste, which are dangerous for the environment due to the hard-to-degrade keratin protein Читати далі

In recent years, cold-adapted enzymes are increasingly used in industrial processes such as the food, textile and beverage industries. Moreover, cold-active enzymes are usually thermolabile and can be inactivated with little heat. This is especially important in reactions where it is necessary to inactivate an enzyme after it has completed Читати далі

Representatives of the Pseudomonas mandelii species are able to exist and multiply in places where the temperature is constantly low. The optimum growth temperature for P. mandelii is 25–30°C, although this bacterium can grow at 4°C but not at 37°C. Therefore, P. mandelii is an excellent example of psychrotolerant bacterium Читати далі

α-L-Rhamnosidase [EC 3.2.1.40], enzyme of the hydrolase family has a wide range of applications: in the food industry, for example, in winemaking to improve the quality and aroma of wines, in the production of citrus juices and drinks to remove bitter components (naringin) that improves the quality and nutritional value Читати далі

The phylogenetic structure of bacteria is not always consistent with the traditional classification scheme based on the phenotypic properties of bacteria. That is one of the problems of modern bacterial taxonomy. In addition, traditional methods to identify bacteria using phenotypic properties have a number of disadvantages. In recent decades, significant Читати далі

The Antarctic region has significant potential to study the biodiversity of microorganisms and to search for bacterial producers of glycolytic and proteolytic enzymes with new properties. The aim was to study the extracellular glycosidase and proteolytic activity of four bacteria strains isolated from black lichens of the cliffs of Galindez Читати далі

The directed search for extremophilic producers in order to obtain hydrolytic enzymes with increased thermal stability has an unconditional practical potential for use in the food and feed industry to improve the quality of the final product. The aim of the work was to study the ability of collection strains Читати далі

About 2 million tons of feathers are produced annually around the world as a by-product of poultry farming. Due to the lack of funds and the complexity of processing, they have become one of the main environmental pollutants. The biodegradation of feathers by keratinolytic microorganisms has proven to be an Читати далі
