INFLUENCE BIODESTRUCTORS ON CELLULOSE AND NATURAL IMPURITY OF FLAX FIBERS IS STUDYING
Abstract
Features of composition and structure of flax fibers as objects of influence of microbic cultures (MC) are investigated. Data on dynamics of change of the cellulose content and natural impurity accompanying it (pectine, hemicellulose, lignin) in the conditions of cultivation of individual MC and a natural complex of microflora are given. On the example of native flax fibers of selection grades Merlyn, Rosinka and Eskalina it is shown that decrease in their explosive loads of 57–71% in the first two weeks of influence of MC, is considerably caused by intensive destruction of pectin and hemicelluloses for 42–52%. It is revealed that the individual cultures of Penicillum sp. strain 96 and and, Bacillus sp., strain 25 allocated from a flax microbiocenosis concede in activity to a natural complex of microflora. Dependence of speed of biodestruction of flax fibers on the contents at them natural impurity, supramolecular structure of cellulose and composition structure is estimated. It is noted to reduction much of constants of speed of biodestruction of polysaccharides after removal of their low-molecular fragments in processes of finishing of fibers.Downloads
