“…RP1, with its capacity to utilize citrate as a carbon source, offers a potential solution for efficient remediation of soil acidity, reducing the need for traditional liming approaches [52]. Additionally, the presence of acidic compounds and free cations in oil-contaminated soils further contributes to their acidic nature [53]. Since biosurfactants can help alleviate and degrade oil pollutants and heavy metals from soils, the production of environmentally-friendly biosurfactants from actinomycetes species like Streptomyces sp.…”

This study aimed to isolate biosurfactant‐producing and hydrocarbon‐degrading actinomycetes from different soils using glycerol–asparagine and starch–casein media with an antifungal agent. The glycerol–asparagine agar exhibited the highest number of actinomycetes, with a white, low‐opacity medium supporting pigment production and high growth. Biosurfactant analyses, such as drop collapse, oil displacement, emulsification, tributyrin agar test, and surface tension measurement, were conducted. Out of 25 positive isolates, seven could utilize both olive oil and black oil for biosurfactant production, and only isolate RP1 could produce biosurfactant when grown in constrained conditions with black oil as the sole carbon source and inducer, demonstrating in situ bioremediation potential. Isolate RP1 from oil‐spilled garden soil is Gram‐staining‐positive with a distinct earthy odor, melanin formation, and white filamentous colonies. It has a molecular size of ~621 bp and 100% sequence similarity to many Streptomyces spp. Morphological, biochemical, and 16 S rRNA analysis confirmed it as Streptomyces sp. RP1, showing positive results in all screenings, including high emulsification activity against kerosene (27.2%) and engine oil (95.8%), oil displacement efficiency against crude oil (7.45 cm), and a significant reduction in surface tension (56.7 dynes/cm). Streptomyces sp. RP1 can utilize citrate as a carbon source, tolerate sodium chloride, resist lysozyme, degrade petroleum hydrocarbons, and produce biosurfactant at 37°C in a 15 mL medium culture, indicating great potential for bioremediation and various downstream industrial applications with optimization.

“…At present, many technologies have been employed to the treatment of OBDC, including continuous supercritical water oxidation, solvent washing, surfactant-based washing, demulsification, pyrolysis, biotreatment, and Fenton oxidation (Adhami et al 2021;Chen et al 2020;Cheng et al 2020;Hu et al 2021;Poyai et al 2020;Yan et al 2011;Ye et al 2017). Among these methods, Fenton oxidation has been widely employed for treatment of oil-contaminated soil and water (Akpoveta et al 2018;Chaturvedi and Katoch 2020a;Chaturvedi and Katoch 2020b;Vilar et al 2020;Xu et al 2020;Xu et al 2017). However, the efficiency of direct Fenton oxidation for OBDC treatment is limited due to the complex emulsification oil-water interface during the reaction process (Wang et al 2017).…”

In this study, demulsification separation-Fenton oxidation technology was employed as a combined technology to treat total petroleum hydrocarbons (TPH) in oil-based drill cuttings (OBDC). Batch experiments were carried out to optimize the technology parameter. Under the optimal condition, 70% and 51% TPH removal rate was obtained for demulsification technology and Fenton oxidation technology, respectively. Eighty-five percent of TPH removal rate was obtained using combination technology of demulsification separation and Fenton oxidation. Multiple characterizations were used to analyze the physical and chemical properties of treated OBDC. The result of XRD pattern indicated the combination technology had no obvious effect for structure phase of OBDC. The results of FTIR, GC-MS, TG-DTG and SEM were used to characterize the treated OBDC. This paper provides an efficient and feasible combined technology for OBDC treatment, which expands a new strategy for the removal of TPH from solid waste
