“…Microbial enhanced oil recovery (MEOR) is also mitigated by biosurfactants. It is a low‐cost, environmentally safe technique (Correia et al, 2021) for recovery, and biodegradation of Diesel. Salt tolerant microorganism like Achromobacter strain A‐8 and its surfactants are also widely popular as potential strains for MEOR (Deng et al, 2020).…”

The Sambhar Salt Lake in Rajasthan, India, offers a unique opportunity to explore halophilic surfactin-producing microorganisms with industrial application. The phylogenetic study, comparative genomics combined with chemotaxonomic research provided insight into the interspecies relativeness of Bacillus sp. Considering the nonribosomal protein sequences (NRPS), Bacillus haynesii strain SAII strain and Bacillus swezeyi strain SEIII showed a high degree of conservation. In silico studies of the isolated Bacillus sp. confirmed the presence of NRPS indicating the presence of surfactin-type lipopeptide biosurfactants. Structural investigation using Fourier transform infrared spectroscopy, liquid quadrupole triple quadrupole mass spectrometry, 1 H Nuclear mass resonance of the crude biosurfactant revealed further similarities among these two Bacillus species. Methyl esters of the crude biosurfactant indicated high likeliness among them and indicated the presence of pentadecanoic acid and tetradecanoic acid as the crucial fatty acids. Enhanced recovery of oil from contaminated sand using 100% crude biosurfactant ranged from 20% AE 0.05 to 69.20% AE 1.22. This opens the door to a bright future for understanding the molecular diversity of closely related halophilic Bacillus sp. and the potential use of the extracted biosurfactants for bioremediation of contaminants.

Enhanced oil recovery (EOR) processes are technologies used in the oil and gas industry to maximize the extraction of residual oil from reservoirs after primary and secondary recovery methods have been carried out. The injection into the reservoir of surface-active substances capable of reducing the surface tension between oil and the rock surface should favor its extraction with significant economic repercussions. However, the most commonly used surfactants in EOR are derived from petroleum, and their use can have negative environmental impacts, such as toxicity and persistence in the environment. Biosurfactants on the other hand, are derived from renewable resources and are biodegradable, making them potentially more sustainable and environmentally friendly. The present review intends to offer an updated overview of the most significant results available in scientific literature on the potential application of biosurfactants in the context of EOR processes. Aspects such as production strategies, techniques for characterizing the mechanisms of action and the pros and cons of the application of biosurfactants as a principal method for EOR will be illustrated and discussed in detail. Optimized concepts such as the HLD in biosurfactant choice and design for EOR are also discussed. The scientific findings that are illustrated and reviewed in this paper show why general emphasis needs to be placed on the development and adoption of biosurfactants in EOR as a substantial contribution to a more sustainable and environmentally friendly oil and gas industry.
