“…The phylogenetic analysis revealed that the CYA20 and CYA27 strains had a 100% sequence similarity (Figure 1) to Acinetobacter baumannii (accession KF498713.1) and Bacillus subtilis (accession AY162130.1). These bacteria commonly correspond to a bacterial group known for crude oil hydrocarbons degradation capability in the sea and mangroves, such as Bacillus, Acinetobacter, Pseudomonas, and Rhodococcus (Chen et al 2020;Kim et al 2019;Syakti et al 2013;Salamat et al 2018). Tan et al (2018) and Sakthipriya et al (2015) reported that A. baumannii and B. subtilis were marine bacteria capable of degrading crude oil pollutants.…”

The pollution of coastal areas caused by oil spills is an environmental issue that needs further attention. Crude oil contains persistent organic pollutants (POPs) that are difficult to degrade. This study aimed to isolate bacterial strains capable of degrading crude oil from the Bekasi coast through bacterial isolate characterization and crude oil biodegradation tests using a crude oil-enriched microcosm model. Two strains with higher TPH degradation values were selected among the isolated bacteria, namely CYA20 and CYA27, which specifically showed values of 46% and 66%, respectively. These strains were tolerant to NaCl concentrations of up to 4% and 12%, respectively, and they were also tolerant to pH values ranging from 5 to 9 and temperatures between 10°C and 50°C. Both strains were shown to utilize POPs, such as phenanthrene and fluorene, produce biosurfactants, and exhibited an emulsification activity in paraffin ranging from 0.373 to 0.533. Phylogenetic analyses identified these bacterial strains as Acinetobacter baumannii CYA20 and Bacillus subtilis CYA27, respectively. The results of this study indicate that these isolates could be developed as biodegradation agents for the bioremediation of crude oil-contaminated environments.

“…In the available literature there are some references to a combined environmental pollution with lead and some PAHs (e.g., [ 24 ]). However, the binary combined effects of B(a)P and lead on the organism have not been the focus of direct studies in the previous works of ours or of anyone else judging by the literature known to us.…”
