Vliv síťování odpadní bílkoviny dialdehydy na biorozklad za anaerobních podmínek

Abstract

The using of the proterins for production of applicable technical films is limited first of all with their small mechanical stability. This property is possible to change positively for example by chemical crosslinking. In this work the proteins hydrolysate from enzymatic hydrolysis of shavings from chromium tanned leaxthers was used as a substrate and as croslinking agents the glutardialdehyde and glyoxal. The degree of crosslinking was simply tested by determination of solubility of the samples and its influence on drop of anaerobic biodegradability was determined by volumetric methanogenic activity test. On the basis of these experiments it was stated, that under described experimental conditions the degree of crosslinking had substantial influence on the rate and also on degree of biodegradation, but without influence on the acceptable degradation of these products in the environment.
