STUDY OF BACTERIA OF THE FAMILY MICROCOCCACEAE DEGRADING MONO(POLY)AROMATIC COMPOUNDS PROMISING FOR THE DEVELOPMENT OF BIOTECHNOLOGIES FOR PURIFICATION OF INDUSTRIAL TERRITORIES OF THE PERM REGION

The research is aimed at solving an urgent problem of microbiology, that studying bacterial degradation processes persistent environmental pollutants, including polycyclic aromatic hydrocarbons (PAHs) and phthalates. study examined the ability bacteria Micrococcaceae family, isolated from technogenically polluted territories Perm Region, to degrade phthalates: esters ortho-phthalic acid, terephthalic acid (TPA), dioctyl terephthalate. We identified 11 strains genera Arthrobacter, Glutamicibacter, Pseudoarthrobacter, Paenarthrobacter, Kocuria, Micrococcus, Rothia capable growing on ortho- phthalic (OPA) ortho-phthalate derivatives (dibutyl phthalate, DBP; dimethyl DMF; diethyl DEP), used as sole source carbon energy. Active destructors phthalates are Kocuria spp. WD25, ML17, Pseudoarthrobacter sp. SA101 Glutamicibacter PB8-1. It has been shown destructor BO25 PB8-1 grow TPA under conditions high salinity (up 60 g/L NaCl). A correlation was found between growth rates a decrease amount in cultivation medium. For first time, decompose saline established. Based characteristics analysis metabolites, it decomposition OPA, OPA (DMF, DBP, DEP) by studied family carried out through formation protocatechuic acid. Thus, result research, active degrading hydrocarbons, those decomposing conditions, were characterized. promising for their use biotechnologies wastewater treatment remediation saline/contaminated soils Region.
