ABSTRACT
The work is devoted to the research of the enzymatic destruction process of solid waste of the primary winemaking enterprises the introduction of advanced technology of their utilization and creation of optimally balanced feed additive. The processing of grapes produces waste, the storage and accumulation of which in environmental components leads to the loss of valuable resource in the composition of waste and leads to the creation of increased levels of environmental hazards. Enzymatic degradation of cellulose in the composition of waste by the cellulase enzyme through the microorganisms' action is the basis of the biotechnological process. To implement this process, it is necessary to determine the main parameters and modes of the bioconversion process, investigation of which the study is devoted. The basic characteristics of the enzymatic degradation process were determined and data were obtained for the technology improvement of solid waste utilization of the wine industry enterprises. Comparative analysis of bioconversion of different types of waste proves that the cellulose enzymatic degradation is the most effective for the grape pomace in the waste, allows us to obtain valuable feed additive and reduce the environmental danger level.
