“…However, investigations into the possibility of replacing traditional chemical compounds with microbial surfactants to formulate fuel or diesel emulsions have been carried out (Coleman and Sibley, 2003; Perfumo et al, 2010). Leng et al (2015) successfully tested a biosurfactant rhamnolipids to obtain nano-scaled glycerol/water-in-diesel microemulsions, which can be formed spontaneously with low energy consumption. In addition, the physicochemical properties of glycerol/water-in-diesel microemulsion were similar to those of diesel.…”

The growing global demand for sustainable technologies that improves the efficiency of petrochemical processes in the oil industry has driven advances in petroleum biotechnology in recent years. Petroleum industry uses substantial amounts of petrochemical-based synthetic surfactants in its activities as mobilizing agents to increase the availability or recovery of hydrocarbons as well as many other applications related to extraction, treatment, cleaning, and transportation. However, biosurfactants have several potential applications for use across the oil processing chain and in the formulations of petrochemical products such as emulsifying/demulsifying agents, anticorrosive, biocides for sulfate-reducing bacteria, fuel formulation, extraction of bitumen from tar sands, and many other innovative applications. Due to their versatility and proven efficiency, biosurfactants are often presented as valuable versatile tools that can transform and modernize petroleum biotechnology in an attempt to provide a true picture of state of the art and directions or use in the oil industry. We believe that biosurfactants are going to have a significant role in many future applications in the oil industries and in this review therefore, we highlight recent important relevant applications, patents disclosures and potential future applications for biosurfactants in petroleum and related industries.

“…Additionally, the decomposition regions of DRL and microemulsion near 500 K at 5 K min À1 , 520 K at 10 K min À1 , 550 K at 20 K min À1 , and 580 K at 40 K min À1 were because of the degradation of RL, which has a higher degradation temperature than diesel as reported in Ref. [9]. The degradation of RL in emulsion was hardly observed due to its low concentration.…”

“…Water fuel emulsion and microemulsion can not only improve the properties of the base fuel, but they can also be further used to upgrade bio-oil [4][5][6], glycerol [7][8][9], and vegetable oil [10,11], etc. The emulsion and microemulsion fuel systems had the advantages, in comparison to the base fuel, of saving energy, enhancing engine torque, improving engine performance, and reducing the emissions of particulate matter (PM), CO, NO x , and persistent organic pollutants [8,[12][13][14].…”

“…This superior alternative chemical is biosurfactant. An attempt was made by Leng et al [70] in using rhamnolipids to obtain a finer glycerol/water-in-diesel microemulsion. These microemulsion fuels were stored at 4 °C without phase separation for over six months and further, it could be directly introduced into fuel to improve the cold flow property.…”

Surfactants are a broad category of tensio-active biomolecules with multifunctional properties applications in diverse industrial sectors and processes. Surfactants are produced synthetically and biologically. The biologically derived surfactants (biosurfactants) are produced from microorganisms with Pseudomonas aeruginosa, Bacillus subtilis Candida albicans and Acinetobacter calcoaceticus as dominant species. Rhamnolipids, sophorolipids, mannosylerithritol lipids, surfactin, and emulsan are well known in terms of their biotechnological applications. Biosurfactants can compete with the synthetic surfactants in terms of performance with established advantages over the synthetic ones including eco-friendliness, biodegradability, low toxicity, and stability over a wide variability of environmental factors. However, at present, the synthetic surfactants are a preferred option in different industrial applications, because of their availability in commercial quantities, unlike the biosurfactants. Usage of synthetic surfactants introduce new species of recalcitrant pollutants to the environment and lead to undesired results where a wrong selection of surfactants is made. Substituting synthetic surfactants with biosurfactants resolves these drawbacks, thus, interest has been intensified in biosurfactant applications in a wide range of industries hitherto considered as experimental fields. This review, therefore, intends to offer an overview of diverse applications where biosurfactants have found useful, with emphases in petroleum biotechnology, environmental remediation and in the agriculture sector. Application of biosurfactant in these settings would lead to industrial growth and environmental sustainability.
