Biodegradation has been regarded as an ideal remediation technique for hydrocarbon pollution. We investigated the potential of 28 Streptomyces species inhabiting different hydrocarbon-polluted soils for the biodegradation of petroleum. The tested isolates were cultured on mineral salts broth containing 2% crude oil as the sole carbon source. Gravimetric analysis of residual crude oil was performed, and the samples that showed the highest percentage of biodegradation were also analyzed via gas chromatography. Among the isolated actinobacteria, Streptomyces aurantiogriseus strain NORA7 (EMCC 28565) stood out for its ability to degrade crude oil (66.28 ± 6.25%). Gas chromatography revealed that docosane, nonadecane, pentacosane, and 7-methylpentadecane were the major compounds detected in the residual treated crude oil. Plackett-Burman design (PB) was used to determine the critical factors impacting the biodegradation process. Response surface methodology (RSM) through Central Composite Design (CCD) was subsequently conducted, and the predicted optimum point of crude oil biodegradation was at 3% crude oil concentration, 0.15 g/L yeast extract, and 25 mm inoculum size. The experimental value after optimum conditions was 70% after 3 weeks, which was close to the predicted value. A pot experiment was performed to investigate the outcomes of ex situ soil bioremediation, and the results were consistent with those of the flask-scale biodegradation experiment with enhanced removal of crude oil (92%). The results revealed that the ability of S. aurantiogriseus NORA7 to biodegrade crude oil could significantly contribute to the eco-friendly recovery of oil-polluted ecosystems and reduce the long-term environmental impact of crude oil pollution.</p>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"36 4","pages":"68"},"PeriodicalIF":3.1,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strain S2 is capable of degrading short-chain PAEs, including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-iso-butyl phthalate (DIBP) and di-n-butyl phthalate (DBP). Sinomonas sp. S2 can completely degrade DBP at concentrations of 400 mg·L<sup>-1</sup> within 24 h. The degradation kinetics of PAEs followed the modified Gompertz model. Strain S2 demonstrated good environmental adaptability thriving at pH ranging from 5 to 9 and temperatures between 20 and 40 °C, indicated by its growth on DBP. The optimal pH and temperature for degradation were found to be 7 and 40 °C, respectively. Additionally, several metabolites of DBP were identified, including phthalic acid (PA), butyl acetate, ethyl propionate and methyl 2-methylbutyrate. The reconstructed degradation pathway of DBP may involve protocatechuic acid, β-carboxy-cis, cis-mucronate and γ-carboxy muconolactone, ultimately leading to the tricarboxylic acid (TCA). In a bioaugmentation experiment involving soil artificially contaminated with DBP, strain S2 could promote the degradation of DBP in soil.
