“…All alkane hydroxylases clustered into separate clusters on the phylogenetic tree and were genus related. The genetic organization of these genes was similar to that of the previously described Acinetobacter strains [ 11 , 36 , 37 , 38 ].…”

“…Upstream of the ferredoxin gene, an AraC-type transcriptional regulator gene was identified that might be responsible for regulating the expression of P450 ( Figure 6 C). In the genome of strain DD78, the genes for two transposases belonging to the IS5 and Tn3 families are located near the P450 operon [ 36 ]. The same type of transposase-encoding genes were also found close to the P450 operon in the genome of the strain ICP1.…”

Potential of Indigenous Strains Isolated from the Wastewater Treatment Plant of a Crude Oil Refinery

Contamination of the environment with crude oil or other fuels is an enormous disaster for all organisms. The microbial communities for bioremediation have been an effective tool for eliminating pollution. This study aimed to determine individual cultures’ and a strain mixture’s ability to utilize alkanes (single alkanes and crude oil). The proper study of pure cultures is necessary to design synergistically working consortia. The Acinetobacter venetianus ICP1 and Pseudomonas oleovorans ICTN13 strains isolated from a wastewater treatment plant of a crude oil refinery can grow in media containing various aromatic and aliphatic hydrocarbons. The genome of the strain ICP1 contains four genes encoding alkane hydroxylases, whose transcription depended on the length of the alkane in the media. We observed that the hydrophobic cells of the strain ICP1 adhered to hydrophobic substrates, and their biofilm formation increased the bioavailability and biodegradation of the hydrocarbons. Although strain ICTN13 also has one alkane hydroxylase-encoding gene, the growth of the strain in a minimal medium containing alkanes was weak. Importantly, the growth of the mixture of strains in the crude oil-containing medium was enhanced compared with that of the single strains, probably due to the specialization in the degradation of different hydrocarbon classes and co-production of biosurfactants.

“…Acinetobacter sp. DD78 possess the ability to produce biosurfactants, which can help improve the bioavailability of the hydrocarbons for biodegradation [54]. The following two treatments were based on biostimulation with the addition of compost in two different ratios, 9:1 (v/v) and 3:2 (v/v), named BE1 and BE4, respectively.…”

Technical advances have converted bioremediation into a large-scale ecosystem service suitable for the treatment of polluted soils worldwide; however, its application in Chile is scarce. The main hurdles that must be addressed include the capacities of such approaches for the treatment of polluted soils, the lack of knowledge about key factors affecting bioremediation costs and the lack of a legal framework to regulate this activity. In this study, the economic performance of the bioremediation of chronically hydrocarbon-polluted urban soils based on bioaugmentation, biostimulation or the combination of both approaches projected to an industrial scale was evaluated. The cost of bioremediation ranged between USD 50.7 and USD 310.4 per m3 of contaminated soil. In addition, the items and activities that had the most significant impacts on the final bioremediation cost, such as compost for biostimulation and bacterial growth media for bioaugmentation-based approaches, were identified. The projected costs were compared against an extensive database of 130 soil bioremediation projects. The bioremediation treatment costs fell within the top 60% of the more expensive projects, highlighting the high effort involved in bioremediation of chronically contaminated soils. This framework can facilitate the decision making of entrepreneurs, consultants, researchers and governmental authorities when launching initiatives to develop a local bioremediation industry capable of cleaning up a high number of polluted sites in Chile.

“…Studies focused in hydrocarbon bioremediation have highlighted the potential of exploring microorganisms containing genes related to hydrocarbon-degrading enzymes ( 1 , 2 ). Specifically, bacteria belonging to genera Pseudomonas ( 3 ) and Acinetobacter ( 4 ) have shown potential to degrade alkanes and aromatic hydrocarbons ( 5 , 6 ). Here, we report the genomic sequencing of three strains retrieved from an abandoned old-century oil exploration well, located in the Cahuita National Park, Costa Rica, which is characterized by a continuous efflux of methane and the presence of a complex mixture of hydrocarbons ( 7 ).…”

We present genome sequences of three Pseudomonadota strains isolated from an abandoned century-old oil exploration well. A Pseudomonas sp. genome showed a size of 5,378,420 bp, while Acinetobacter genomes sized 3,522,593 and 3,864,311 bp. Genomes included catabolic genes for benzoate, 4-hydroxybenzoate, salicylate, vanillate, indoleacetate, anthranilate, n -alkanes, 4-hydroxyphenylacetate, phenylacetate, among others.
