Abstract

Phenol and PHENOLic compounds are highly toxic substances that are found as monoaromatic compounds in various industrial effluents from oil refineries, petrochemical plants, (coal) mines, and PHENOL resin plants. Their discharge into the environment, especially in water resources, causes serious toxicity. Traditionally, physicochemical methods have been used for the removal of PHENOL and PHENOLic compounds. Nowadays, BIOREMEDIATION is known to be the best method for PHENOL removal from WASTEWATER. The objective of the present study was twofold: isolation and identification of PHENOL degrading BACTERIA in the effluent from Golgohar Mine in Sirjan. For this purpose, samples were collected from different sections at Golgohar Mine and its effluent. PHENOL degrading BACTERIA were isolated via enrichment of the samples in the Bushnell Hass medium with PHENOL used as the only source of carbon and energy. The predominant PHENOL degrader BACTERIA were selected by measuring turbidity at 600 nm. The BACTERIA were subsequently identified by amplification of 16S rRNA withspecific primers and PCR sequencing. In this study, 17 strains of PHENOL degrader BACTERIA were isolated in soil and WASTEWATER samples collected from different zones of the mine.Screening methods confirmed that 4 strains exhibit a better capability for PHENOL degradation as evidenced by their capability to degrade 0.4 g/l of PHENOL. Molecular identification showed that these BACTERIA belong to the species Pesudomonas sp, Nitrratireductor sp., and Salegentibacter sp. The results also show that the effluent from Golgohar Mine in Sirjan contains many PHENOL degrading BACTERIA. The use of these BACTERIA in the treatment process may lead to a significant reduction in PHENOL pollution in the mineral effluent.
