the major sustainable ways to remove phenol contaminated

the major sustainable ways to remove phenol
contaminated environment and it has been confirmed on its rapid and growth in
extreme condition using dangerous compound as the sole of carbon and energy. It also reported that microbes can adapt rapidly
to an extreme condition in waste streams, example; phenol, atrazine,
nitroaromatics, chlorophenol, chlorobenzene, and chloroalkanes (Mahiudddin
and Fakhruddin 2012). There is interesting evidence which provides
that even uncultured bacteria play a very vital role in the bioremediation and
biodegradation in environmental pollution (Zhang, Berry
et al. 2015). Studies showed that physicochemical approach of
biodegradation was effective in environmental protection years ago such as
hydrogen peroxide, ozonation, ultraviolet, Fenton’s reagent was in removing
phenol and its major challenges are the high cost of operation. From the
biological method of removing this phenol, it has placed on the high advantage
over physiochemical method because is more efficient, cost-effective technology
and friendly (Liu, Xie et
al. 2016), saves energy and it has the tendency to avoid
secondary pollution(Gu, Wu et al.
2017). Due to the fact that the phenol-degrading
bacteria in Qhinhai river has or may not be fully studied. The identification
of strain 119-2 as degrading bacteria was based on morphological, biochemical,
16RNA analysis and subjecting the degrading bacteria to different phenol
concentration to evaluate its degrading potentials. However, the existence of
phenol in some environment has given several microorganisms such as bacteria to
withstand the high concentration of phenol and be able to utilize phenol as the
source of carbon and energy. So bacteria have been confirmed to grow in the
presence of high concentration of aromatic compound (Hamedo, El-Shamy
et al.). The
method of screening for salt tolerance and phenol-degrading bacteria strains is
very important for improving the effectiveness of the biological method of
treatment of wastewater. Therefore, this has to lead to the isolation of
different bacteria from a saline environment to help in
