“…The capability of aerobic heterotrophic bacteria and cyanobacteria from Bodo creek to degrade poly aromatic hydrocarbons has been reported previously. Ichor, et al [18][19][20] reported on biodegradation of phenanthrene, PAH's, fluoranthene, benzo(b)fluoranthene and benzo(k)fluoranthene by aerobic heterotrophic bacteria and cyanobacteria resident in Bodo creek. The cyanobacteria isolates are as reported by Ichor and the consortium of aerobic heterotrophic bacteria and cyanobacteria evolutionary history inferred as contained in Ichor [19].…”

Biodegradation of anthracene, benzo(a)anthracene and dibenzo(a,h)anthracene by indigenous strains of aerobic heterotrophic bacteria and cyanobacteria isolated from Bodo creek -a moderate salt aquatic environment polluted with crude oil was monitored for 56 days using GC-MS. Anthracene was mineralized to 0.1, 0.001 and 0.08 mg/l by aerobic heterotrophic bacteria cyanobacteria and consortium of aerobic heterotrophic bacteria and cyanobacteria respectively. Benzo(a)anthracene was reduced to 0.03, 0.01 and 0.02 mg/l in the treatments of aerobic heterotrophic bacteria cyanobacteria and consortium of aerobic heterotrophic bacteria and cyanobacteria respectively where as dibenzo(a,h)anthracene was reduced to 0 mg/l in all the treatment options on the 56th day monitored. Fluctuations in the quantity of PAHs monitored and was observed at some weeks since it did not follow a straight and consistent reduction pattern but did not vary significantly with time when compared with the control at p>0.05 since the monitored PAHs were degraded in both the treatment options and the control.

“…PAHs are highly recalcitrant molecules, and they are not easy to remove due to their hydrophobicity and low water solubility. Thus, it is possible to find them in crude oil, asphalt, creosote, tars, and waste products associated with wood preservatives [ 6 , 7 ]. The simplest PAH is naphthalene, because it has only two benzene rings and narrowly speaking is not polycyclic.…”

Microbial degradation of aromatic hydrocarbons is an emerging technology, and it is well recognized for its economic methods, efficiency, and safety; however, its exploration is still scarce and greater emphasis on cyanobacteria–bacterial mutualistic interactions is needed. We evaluated and characterized the phenanthrene biodegradation capacity of consortium dominated by Fischerella sp. under holoxenic conditions with aerobic heterotrophic bacteria and their molecular identification through 16S rRNA Illumina sequencing. Results indicated that our microbial consortium can degrade up to 92% of phenanthrene in five days. Bioinformatic analyses revealed that consortium was dominated by Fischerella sp., however different members of Nostocaceae and Weeksellaceae, as well as several other bacteria, such as Chryseobacterium, and Porphyrobacter, were found to be putatively involved in the biological degradation of phenanthrene. This work contributes to a better understanding of biodegradation of phenanthrene by cyanobacteria and identify the microbial diversity related.

Cyanobacteria, also known as blue-green (micro)algae, are able to sustain many types of chemical stress because of metabolic adaptations that allow them to survive and successfully compete in a variety of ecosystems, including polluted ones. As photoautotrophic bacteria, these microorganisms synthesize aromatic amino acids, which are precursors for a large variety of substances that contain aromatic ring(s) and that are naturally formed in the cells of these organisms. Hence, the transformation of aromatic secondary metabolites by cyanobacteria is the result of the possession of a suitable “enzymatic apparatus” to carry out the biosynthesis of these compounds according to cellular requirements. Another crucial aspect that should be evaluated using varied criteria is the response of cyanobacteria to the presence of extracellular aromatic compounds. Some aspects of the relationship between aromatic compounds and cyanobacteria such as the biosynthesis of aromatic compounds, the influence of aromatic compounds on these organisms and the fate of aromatic substances inside microalgal cells are presented in this paper. The search for this information has suggested that there is a lack of knowledge about the regulation of the biosynthesis of aromatic substances and about the transport of these compounds into cyanobacterial cells. These aspects are of pivotal importance with regard to the biotransformation of aromatic compounds and understanding them may be the goals of future research.
