Regulation of the synthesis of cellulase and macerase enzymes by the immobilized association of Aspergillus awamori 1-8 and Aspergillus niger 355
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
The regulation of the synthesis of cellulase and macerase enzymes by nutrient medium composition and cultivation conditions of the association of micromycetes Aspergillus awamori 1-8 and Aspergillus niger 355 was studied. Optimal carbon and nitrogen sources, as well as the absence of catabolite repression in the enzymes production have been established. The level of biosynthesis of enzymes in Aspergillus awamori 1-8 and Aspergillus niger 355 depends not only on the nutrient medium composition, but also on the method of their cultivation. Immobilization of enzymes producers on a carrier and their cultivation in a filamentous-spongy structure allows to obtain the target product for long period of time.
