“…Although among halophilic bacteria, Halomonas sp. has been shown to utilize a wide range of readily available substrates as energy sources for its fast growth (Ali et al 2016) and is multi-metal resistant (Govarthanan et al 2017), to our knowledge there are few studies on PAH degrading Halomonas isolated from marine waters (Gasperotti et al 2015;Corti Monzón et al 2018;Izzo et al 2019;Govarthanan et al 2020). It is worth noting that H. meridiana and H. sulfidaeris strains retrieved from deep sea sediments were also previously reported as PAH degraders (Cui et al 2008;Yuan et al 2015).…”

“…PAHs are among the most persistent organic pollutants in the environment, and during the last years there has been increasing concern about contamination of these compounds in marine systems owing to their detrimental biological effects, toxicity and carcinogenicity (Haritash and Kaushik 2009). Although it is well known that bacterial degradation plays an important role in PAHs removal from marine environments (Dong et al 2015;Sakshi Sing and Haritash 2020), nowadays most studies have reported on PAHdegrading bacteria isolated from PAH-contaminated soil or sediments (Haritash and Kaushik 2009; Dell'Anno et al 2020), and little is known about bacteria isolated from sea or brackish waters (Izzo et al 2019;Govarthanan et al 2020).…”

Hydrocarbon degrading bacteria (HDB) were monitored since 2006 to 2018 at the Permanent Environmental Studies Station (EPEA), in order to analyze its abundance and the potentiality to metabolize these pollutants. The presence of HDB was detected with counts values ranging between 103 and 105 UFC ml-1. A slight increase was observed over time, which could be linked to changes in marine temperature reported within the last years. Thirty-six HDB were tested for growth on various hydrocarbons and some of them showed a broad biodegradation profile. Moreover, from phenanthrene (Phe) enrichment cultures, five strains were phylogenetically identified as Halomonas sp. E1, E2 and E3; Rhodococcus sp. E4 and Pseudomonas sp. E5. Complete Phe degradation was demonstrated for E4 and E5 strains, while E1, E2, E3 and E4 strains displayed surfactant production. This study contributed with the first knowledge about the intrinsic HC biodegradation potential by bacterial communities at EPEA. Some of the strains exhibited physiological properties that might have ecological significance on environmental alterations as the presence of pollutants. Particularly, Rhodococcus sp. E4 could be an alternative for microbial selection in the degradation of PAHs. Further studies are needed to evaluate the impact of the climate change on microbial-mediated detoxification processes.

“…Degradation of 1-naphthylamine on TRM 85114 T growth was performed in batch experiments (Govarthanan et al 2020). The isolate TRM 85114 T was inoculated into 250 mL Erlenmeyer flasks containing 100 mL of 12% MGM medium, and 50 mg/L concentration of 1-naphthylamine was added into the culture flasks at the same time, the resuspension was incubated at 30 ℃ temperature in a shaking incubator (180 rpm) for 14 days.…”

A Gram-staining-negative, aerobic, rod-shaped bacterium, designated strain TRM 85114 T , was isolated from Jincaotan wetland in Pamir Plateau, PR China. According to the study, we found it have an ability to degrade 1-naphthylamine. Strain TRM 85114 T grow at 4-35 ℃ (optimum, 30 ℃), pH of 6.0-9.0 (optimum, pH 6.0) and can tolerate 1%-10% (w/v) NaCl (optimum, 3%). Phylogenetic analysis of 16S rRNA gene sequences revealed that strain TRM 85114 T was affiliated of the genus Halomonas , sharing high sequence similarity (97.3%) with the type strain of Halomonas korlensis XK1 T . The primary cellular fatty acids of strain TRM 85114 T were C 16:0 and C 19:0 cyclo ω 8 c . The predominate respiratory quinone was Q-9. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, lyso-phospatidylglycerol, phospholipids of unknown structure containing glucosarmine, and five unidentified lipids. The genomic DNA G+C content of strain TRM 85114 T was 61.6 mol%. Calculated the average nucleotide identities and the digital DNA-DNA hybridization values between strain TRM 85114 T and the related type Halomonas strains further revealed that TRM 85114 T represented a novel species of the genus Halomonas , for which the name Halomonas jincaotanensis sp. nov. is proposed. The type strain is TRM 85114 T (CCTCC AB 2021006 T =LMG 32311 T ).
