cze Studium TNT metabolismu v rostlinách a jeho praktická aplikace v odmoření prostředí Jelikož znečištění míst TNT (2,4,6-trinitrotoluenem) je environmentální problém po celém světě, osud jeho degradačních. produktů vyžaduje také pozornosti. Studium působení TNT na rostliny je soustředěno i na degrdn. 4-amino--2,6-dinitrotoluene (4-ADNT). Dva rostlinné druhy Senecio jacobaea a Buphthalmum salicifolium kultivované v in vitro podmínkách v přítomnosti různých konc.. 4-ADNT. Nejvyšší konc. 50 mg/litr 4-ADNT byla degradovaná rostlinami během čtrnácti dní ale jakýkoliv významější degrdn. produkt nebyl specifikován. TNT;ADNT;fytoremediace;biodegradace;metabolismus rostlin
eng Study of TNT Metabolism in Plants and its practical Application for Environment Decontamination Although a contamination of sites by TNT is an environmental problem all over the world, the fate of its degradation products claims attention as well. A study of metabolism of TNT in plants was focused on degradation of 4-amino-2,6-dinitrotoluene (4-ADNT), a stable degradation product. Two plant species Senecio jacobea and Buphthalmum salicifolium cultivated under in vitro conditions in the presence of different concentration of 4-ADNT for 3 weeks. The highest concentration 50 mg/l of 4-ADNT was degraded by plants within two weeks but any major degradation product was not detected in the medium. The IC50 was not determined in the range of used concentration therefore a linear regression was used for prediction of the IC50 and 61,8 mg/l and 70,2 mg/l were calculated for S. jacobea and B. salicifolium, respectively.
