the major sustainable ways to remove phenolcontaminated environment and it has been confirmed on its rapid and growth inextreme condition using dangerous compound as the sole of carbon and energy. It also reported that microbes can adapt rapidlyto an extreme condition in waste streams, example; phenol, atrazine,nitroaromatics, chlorophenol, chlorobenzene, and chloroalkanes (Mahiudddinand Fakhruddin 2012). There is interesting evidence which providesthat even uncultured bacteria play a very vital role in the bioremediation andbiodegradation in environmental pollution (Zhang, Berryet al.
2015). Studies showed that physicochemical approach ofbiodegradation was effective in environmental protection years ago such ashydrogen peroxide, ozonation, ultraviolet, Fenton’s reagent was in removingphenol and its major challenges are the high cost of operation. From thebiological method of removing this phenol, it has placed on the high advantageover physiochemical method because is more efficient, cost-effective technologyand friendly (Liu, Xie etal. 2016), saves energy and it has the tendency to avoidsecondary pollution(Gu, Wu et al.2017).

Due to the fact that the phenol-degradingbacteria in Qhinhai river has or may not be fully studied. The identificationof strain 119-2 as degrading bacteria was based on morphological, biochemical,16RNA analysis and subjecting the degrading bacteria to different phenolconcentration to evaluate its degrading potentials. However, the existence ofphenol in some environment has given several microorganisms such as bacteria towithstand the high concentration of phenol and be able to utilize phenol as thesource of carbon and energy. So bacteria have been confirmed to grow in thepresence of high concentration of aromatic compound (Hamedo, El-Shamyet al.). Themethod of screening for salt tolerance and phenol-degrading bacteria strains isvery important for improving the effectiveness of the biological method oftreatment of wastewater. Therefore, this has to lead to the isolation ofdifferent bacteria from a saline environment to help in
