The Present and the Desirable Future of the Waste Treatment and Utilization in .A.S.A. Lišov
FRANTÍK, Jan
The subject of these theses contains an evaluation of the waste policy in the A.S.A. České Budějovice company. More precisely is oriented on waste dump in Lišov. Firstly, as an result of my work, the proposition of better economic and technology solution is offered. The proposal covered also the problem of the ecological waste handling. In the frame of the ecological treatment the biodegradation is included. This will lead to another direction of the waste treatment policy. The way is under EU environmental policy legislature. The final result of these theses is a real project of the waste assorting line with the direct link towards the manipulation with the biodegradation material. These procedures are proposed in accordance with the economical situation of the A.S.A. České Budějovice division.

The aim of this study was to evaluate the mutagenicity of three mixtures of synthetic dyes used in textile industry. Detection of mutagenicity was carried out with three samples containing residues of textile dyes obtained from textile company Jitex Písek. Two different biodegradation process were used for elimination of genotoxicity, biodegradation using the bacterial activated sludge and the enzyme systém of the ligninolytic fungus Irpex lacteus. The genotoxicity of the samples was detected by the Ames test with and without metabolic activation in vitro, using S9 liver microsomal fraction and cofactor mixture. Salmonella typhimurium His- strain TA98 was employed for detection of frameshift mutations in the Ames test. During two different biodegradation processes (using bacterial activated sludge and the ligninolytic fungus Irpex lacteus), the change of mutagenicity of the degradation products of dyes was monitored
