Abstract
Sponges forms association with many bacteria that serve as sources of new bioactive compounds. The compounds are produced in response to environmental and nutritional conditions of the environment that enable them to protect their host from colonization. In this study, three sponge bacterial endophytes were isolated, identified, and subjected to solvent extraction processes. The identified bacteria are Bacillus amyloquifaciens, Bacillus paramycoides, and Enterobacter sp. The bacteria were cultured in two different fermentation media with varying nutritional composition for the extraction process. The extracts were evaluated for antibacterial and antibiofilm activity against microfouling bacteria and the chemical composition of each extract was analyzed via gas chromatography-mass spectrometry (GC-MS). The extract from the endophytes shows varying antibacterial and antibiofilm activity against the tested strains. Several compounds were detected from the extracts including some with known antibacterial/antibiofilm activity. The results showed variations in activity and secondary metabolite production between the extracts obtained under different nutritional composition of the media. In conclusion, this study indicated the role of nutrient composition in the activity and secondary metabolites production by bacteria associated with sponge Also, this study confirmed the role of sponge bacterial endophytes as producers of bioactive compounds with potential application as antifouling (AF) agents.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) and heterocyclic derivatives are organic pollutants which threaten ecosystems and human beings. In this study, a new strain, Shinella sp. FLN 14, was isolated and characterized. It can utilize fluorene as its sole carbon source and effectively co-metabolize multiple PAHs and heterocyclic derivatives, including phenanthrene, acenaphthene, and fluoranthene. Two possible metabolic pathways are proposed (i.e., salicylic acid pathway and phthalic acid pathway). Whole-genome sequencing revealed that strain FLN14 possesses a chromosome and four plasmids. However, when combined with ensemble genetic information, novel fluorene-degrading functional gene clusters were not located within the genome of FLN 14, except for some new dioxygenases and electron transport chains, which typically initiate the oxidation of aromatic compounds. In wastewater bioremediation, strain FLN14 removed nearly 95 % of PAHs within 5 days and maintained high degrading activity during the 18-day reaction compared to the control. Overall, our study provides a promising candidate to achieve bioremediation of PAHs-contaminated environments.

Abstract
A bacterium was isolated from sludge-contaminated soil in a petroleum refinery and tested for its ability to degrade aliphatic hydrocarbon compounds present in petroleum sludge. The isolate was grown on minimal salt media agar supplemented with 1% (w/v) petroleum sludge. The isolate was tentatively identified as Methylobacterium s p. s t rain ZASH based on the partial 16s rDNA molecular phylogeny. The bacterium grew optimally between the temperatures of 30°C and 35°C, pH 7 and 7.5, 0.5% and 1.5% (v/v) Tween 80 as the surfactant, and between 1% and 2% (w/v) peptone as the nitrogen source. The constants derived from the Haldane equation were μmax = 0.039 hr-1, Ks = 0.385% (w/v) total petroleum hydrocarbons (TPH) or 3,850 mg/L TPH, and Ki =1.12% (w/v) TPH or 11,200 mg/L. The maximum biodegradation rate exhibited by this strain was 19 mg/L/hr at an initial TPH concentration of 10,000 mg/L. Gas chromatography analysis revealed that after 15 days the strain was able to degrade all aliphatic n-alkanes investigated with different efficiencies. Shorter n-alkanes were generally degraded more rapidly than longer n-alkanes with 90% removal for C-12 compared to only 30% removal for C-36. The addition of sawdust did not improve bacterial degradation of petroleum hydrocarbons, but it assisted in the removal of remaining undegraded hydrocarbons through adsorption.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) with their carcinogenic, teratogenic, and mutagenic effects can cause great damage to the ecosystem and public health when present in water. With bioremediation, PAH contamination in water environment can be greatly reduced in an eco-friendly manner. It has thus become the research focus for many environmental scientists. In this study, a bibliometric analysis on three-decade (1990-2022) development of PAH bioremediation in water environment was conducted from temporal and spatial dimensions using CiteSpace. A total of 2480 publications, obtained from Web of Science core collection database, were used to explore the basic characteristics, hotspots, and prospects of the research area. The results showed that (1) bioremediation/biodegradation of PAHs in water environment has been getting researchers' attention since 1990, and is gaining even more traction as time goes on. (2) In terms of countries, China and the USA were the major contributors in this research area, while at the institutional level, the Chinese Academy of Sciences has produced the most research results. However, international cooperation across regions was lacking in the field. (3) Environment Science and Technology, Chemosphere, Applied and Environment Microbiology, Journal of Hazardous Materials, and Environment Pollution were the 5 most cited journals in this field. (4) There were three major stages the field has gone through, each with distinct research hotspots, including initial stage (1990-1994), mechanism investigation (1995-2000), and application exploration (2001-2010; 2011-2022). Finally, research perspectives were proposed, covering three directions, namely, bioavailability, immobilization, and viable but nonculturable (VBNC) bacteria.

Biodegradation of high molecular weight hydrocarbons under saline condition by halotolerant Bacillus subtilis and its mixed cultures with Pseudomonas species. Sci Rep 2022; 12:13227. [PMID: 35918482 PMCID: PMC9345985 DOI: 10.1038/s41598-022-17001-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 07/19/2022] [Indexed: 11/08/2022] Open
Abstract
Biodegradation of high-molecular-weight petroleum hydrocarbons in saline conditions appears to be complicated and requires further investigation. This study used heavy crude oil to enrich petroleum-degrading bacteria from oil-contaminated saline soils. Strain HG 01, with 100% sequence similarity to Bacillus subtilis, grew at a wide range of salinities and degraded 55.5 and 77.2% of 500 mg/l pyrene and 500 mg/l tetracosane, respectively, at 5% w/v NaCl. Additionally, a mixed-culture of HG 01 with Pseudomonas putida and Pseudomonas aeruginosa, named TMC, increased the yield of pyrene, and tetracosane degradation by about 20%. Replacing minimal medium with treated seawater (C/N/P adjusted to 100/10/1) enabled TMC to degrade more than 99% of pyrene and tetracosane, but TMC had lesser degradation in untreated seawater than in minimal medium. Also, the degradation kinetics of pyrene and tetracosane were fitted to a first-order model. Compared to B. subtilis, TMC increased pyrene and tetracosane's removal rate constant (K1) from 0.063 and 0.110 per day to 0.123 and 0.246 per day. TMC also increased the maximum specific growth rate of B. subtilis, P. putida, and P. aeruginosa, respectively, 45% higher in pyrene, 24.5% in tetracosane, and 123.4% and 95.4% higher in pyrene and tetracosane.

Abstract
Pseudomonas citronellolis SJTE-3 was isolated as a highly efficient microorganism for biodegradation and valorization of drilling fluids (DF) wastewater. The strain metabolised DF and oily mud exhibiting up to 93%, 86%, 85% and 88% of chemical oxygen demand (COD), n-dodecane, n-tetradecane and naphthalene removal efficiency respectively. Enhanced bioconversion was enabled through production of biosurfactants that reduced the surface tension of water by 53% and resulted in 43.3% emulsification index (E24), while synthesizing 24% of dry cell weight (DCW) as medium-chain-length polyhydroxyalkanoates (PHA). Expression from the main pathways for alkanes and naphthalene biodegradation as well as biosurfactants and PHA biosynthesis revealed that although the alkanes and naphthalene biodegradation routes were actively expressed even at stationary phase, PHA production was stimulated at late stationary phase and putisolvin could comprise the biosurfactant synthesized. The bioconversion of toxic petrochemical residues to added-value thermoelastomers and biosurfactants indicate the high industrial significance of P. citronellolis SJTE-3.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are widely distributed in the environment and pose a serious threat to human health. Due to their unfavorable biological effects and persistent properties, it is extremely urgent to effectively degrade PAHs that are present in the environment, especially in wastewater. In this study, we obtained an efficient bacterial consortium (PDMC), consisting of the genera Sphingobium (58.57-72.40%) and Pseudomonas (25.93-39.75%), which is able to efficiently utilize phenanthrene or dibenzothiophene as the sole carbon source. The phenanthrene-cultivated consortium could also degrade naphthalene, acenaphthene, fluorene, anthracene, fluoranthene, benzo[a]anthracene, dibenzofuran, carbazole and indole, respectively. Furthermore, we identified the multiple key intermediates of aforementioned 11 substrates and discussed proposed pathways involved. Notably, a novel intermediate 1,2-dihydroxy-4a,9a-dihydroanthracene-9,10-dione of anthracene degradation was detected, which is extremely rare compared to previous reports. The PDMC consortium removed 100% of PAHs within 5 days in the small-scale wastewater bioremediation added with PAHs mixture, with a sludge settling velocity of 5% after 10 days of incubation. Experiments on the stability reveal the PDMC consortium always has excellent degrading ability for totaling 24 days. Combined with the microbial diversity analysis, the results suggest the PDMC consortium is a promising candidate to facilitate the bioremediation of PAHs-contaminated environments.

Abstract
The present study was conducted to compare the efficiency of different microbial mixed-cultures consists of fifteen oil-degrading microorganisms with different combinations. The investigation was targeted toward the removal of 500 mg/l pyrene and 1% w/v tetracosane, as single compounds or mixture. Sequential Fungal-Bacterial Mixed-Culture (SMC) in which bacteria added one week after fungi, recorded 60.76% and 73.48% degradation for pyrene and tetracosane; about 10% more than Traditional Fungal-Bacterial Mixed-Culture (TMC). Co-degradation of pollutants resulted in 24.65% more pyrene degradation and 6.41% less tetracosane degradation. The non-specified external enzymes of fungi are responsible for initial attacks on hydrocarbons. Delayed addition of bacteria and co-contamination would result in higher growth of fungi which increases pyrene degradation. The addition of Rhamnolipid potently increased the extent of pyrene and tetracosane degradation by approximately 16% and 23% and showed twice better performance than Tween-80 in 20 times less concentration. The results indicated the importance of having sufficient knowledge on the characteristics of the contaminated site and its contaminants as well as oil-degrading species. Gaining this knowledge and using it properly, such as the later addition of bacteria (new method of mixed-cultures inoculation) to the contaminated culture, can serve as a promising approach.

Abstract
Degradation of petroleum hydrocarbon under extreme conditions such as high salinity, temperature and pH was difficult due to unavailability of potential bacterial strains. The present study details the efficiency of extremophilic bacterial consortium in biodegradation of different petroleum hydrocarbons and treatment of petroleum refinery wastewater under extreme condition. Extreme condition for the degradation of petroleum hydrocarbons was optimized at 8% salinity, pH-10 and temperature-60 °C. The consortium recorded complete degradation of low molecular weight (LMW) petroleum hydrocarbons (200 ppm) such as anthracene, phenanthrene, fluorene and naphthalene in 8 days under optimized extreme condition. High molecular weight (HMW) hydrocarbons such as pyrene (100 ppm), benzo(e)pyrene (20 ppm), benzo(k)fluoranthene (20 ppm) and benzo(a)pyrene (20 ppm), revealed 93%, 60%, 55% and 51% degradation by the extremophilic consortium under optimized extreme condition. The extremophilic consortium mineralized fluorene (61%) at high saline condition up to 24%. Addition of yeast extract potently accelerated the biodegradation under extreme condition. Treatment of petroleum refinery wastewater in continuous stirred tank reactor recorded 92% COD removal with complete removal of LMW hydrocarbons in 16 days and 91% of HMW hydrocarbons in 32 days under extreme condition. The hydrocarbons degrading extremophilic consortium possessed Ochrobactrum, Bacillus, Marinobacter, Pseudomonas, Martelella, Stenotrophomonas and Rhodococcus.

Abstract
We investigated the efficiency of a benthic diatom-associated bacteria in removing benzo(a)pyrene (BaP) and fluoranthene (Flt). The diatom, isolated from a PAH-contaminated sediment of the Bizerte Lagoon (Tunisia), was exposed in axenic and non-axenic cultures to PAHs over 7 days. The diversity of the associated bacteria, both attached (AB) and free-living bacteria (FB), was analyzed by the 16S rRNA amplicon sequencing. The diatom, which maintained continuous growth under PAH treatments, was able to accumulate BaP and Flt, with different efficiencies between axenic and non-axenic cultures. Biodegradation, which constituted the main process for PAH elimination, was enhanced in the presence of bacteria, indicating the co-metabolic synergy of microalgae and associated bacteria in removing BaP and Flt. Diatom and bacteria showed different capacities in the degradation of BaP and Flt. Nitzschia sp. harbored bacterial communities with a distinct composition between attached and free-living bacteria. The AB fraction exhibited higher diversity and abundance relative to FB, while the FB fraction contained genera with the known ability of PAH degradation, such as Marivita, Erythrobacter, and Alcaligenes. Moreover, strains of Staphylococcus and Micrococcus, isolated from the FB community, showed the capacity to grow in the presence of crude oil. These results suggest that a "benthic Nitzschia sp.-associated hydrocarbon-degrading bacteria" consortium can be applied in the bioremediation of PAH-contaminated sites.

Abstract
Pyrene is one of the polycyclic aromatic hydrocarbons, which are a potential threat to ecosystems due to their mutagenicity, carcinogenicity, and teratogenicity. In this study, several bacteria were isolated from oil contaminated sludge and their capacity to biodegrade pyrene was investigated. Of these bacteria, the monoculture strain LZ6 showed the highest pyrene anaerobic biodegradation rate of 33% after 30 days when the initial concentration was 50 mg/L, and was identified as Klebsiella sp. LZ6 by morphological observation, the GENIII technology of Biolog, and 16S rDNA gene sequence analysis. The influence of various culture parameters on the biodegradation of pyrene were evaluated, and Klebsiella sp. LZ6 all showed the high degradation rate at an inoculum of 10-20% (v/v), pH 6.0-8.4, temperature 30-38°C, and initial pyrene concentration of 50-150 mg/L. The intermediate metabolites of the anaerobic biodegradation were analyzed by GC-MS. Several metabolites were identified, such as pyrene, 4,5-dihydro-, phenanthrene, dibenzo-p-dioxin, and 4-hydroxycinnamate acid. The anaerobic metabolic pathway for the degradation of pyrene was inferred by the products. It seems that pyrene was first reduced to pyrene,4,5-dihydro- by the adding of two hydrogen atoms, and then the carbon-carbon bond cleavage at saturated carbon atoms generated phenanthrene.

Abstract
Benzo[a]pyrene is a high-molecular-weight polycyclic aromatic hydrocarbon highly recalcitrant in nature and thus harms the ecosystem and/or human health. Therefore, its removal from the marine environment is crucial. This research focuses on benzo[a]pyrene degradation by using enriched bacterial isolates in consortium under saline conditions. Bacterial isolates capable of using benzo[a]pyrene as sole source of carbon and energy were isolated from enriched mangrove sediment. These isolates were identified as Ochrobactrum anthropi, Stenotrophomonas acidaminiphila, and Aeromonas salmonicida ss salmonicida. Isolated O. anthropi and S. acidaminiphila degraded 26% and 20%, respectively, of an initial benzo[a]pyrene concentration of 20 mg/L after 8 days of incubation in seawater (28 ppm of NaCl). Meanwhile, the bacterial consortium decomposed 41% of an initial 50 mg/L benzo[a]pyrene concentration after 8 days of incubation in seawater (28 ppm of NaCl). The degradation efficiency of benzo[a]pyrene increased to 54%, when phenanthrene was supplemented as a co-metabolic substrate. The order of biodegradation rate by temperature was 30°C > 25°C > 35°C. Our results suggest that co-metabolism by the consortium could be a promising biodegradation strategy for benzo[a]pyrene in seawater.
