BIOCHEMICAL FEATURES OF THE DEGRADATION OF POLLUTANTS BY RHODOCOCCUS AS A BASIS FOR CONTAMINATED WASTEWATERAND SOIL CLEANUP

摘要

Rhodococcus bacteria are considered to be promising degraders of persistent pollutants and are the basis of biological preparations for contaminated wastewater and soil cleanup. Biotechnological application of this group of bacteria is based on the pecuUaraties of their metaboUsm. This review briefly discusses the following main points:I. Growth of Rhodococcus on various aromatic substrates II. Chloro/methylcatechol transformation pathways3- Chlorocatechol branch of the modified ortho-pathway4- Chlorocatechol branch of the modified ortho-pathway Modified 3-chlorocatechol branch in Rhodococcus opacus 1CP Meta-cleavage of chlorocatecholsModified pathway for methylcatechol degradationIII. Approaches to the enhancement of degradation activityIV. Rhodococcus-based biopreparationsIV. Prospects
