“…It has been discovered to be quite helpful in oil bioremediation procedures(Elshafie et al 2015 ). Although sophorolipids can lower interfacial and surface tension, they are ineffective emulsifiers (SajadiBami et al 2022 ). The most prevalent sophorolipids are those made by yeast such Torulopsis bombicola, T. apicola , and T. petrophilum (Shekhar et al 2015 ).…”

Globally, there is a huge demand for chemically available surfactants in many industries, irrespective of their detrimental impact on the environment. Naturally occurring green sustainable substances have been proven to be the best alternative for reducing reliance on chemical surfactants and promoting long-lasting sustainable development. The most frequently utilized green active biosurfactants, which are made by bacteria, yeast, and fungi, are discussed in this review. These biosurfactants are commonly originated from contaminated sites, the marine ecosystem, and the natural environment, and it holds great potential for environmental sustainability. In this review, we described the importance of biosurfactants for the environment, including their biodegradability, low toxicity, environmental compatibility, and stability at a wide pH range. In this review, we have also described the various techniques that have been utilized to characterize and screen the generation of microbial biosurfactants. Also, we reviewed the potential of biosurfactants and its emerging applications in the foods, cosmetics, pharmaceuticals, and agricultural industries. In addition, we also discussed the ways to overcome problems with expensive costs such as low-cost substrate media formulation, gravitational techniques, and solvent-free foam fractionation for extraction that could be employed during biosurfactant production on a larger scale.

“…Thus, fungal biosurfactants or biosurfactant-producing fungal bioinoculants are ecological alternatives to reduce environmental toxicity, since fungal metabolism is induced to produce such amphiphilic molecules when the strain is exposed to hydrocarbons [110][111][112]. The main physicochemical properties of biosurfactants for environmental remediation are related to the reduction of surface/interfacial tension and increase of surface area in different fluid phases, which results in better mobility, solubility, emulsification and bioavailability of contaminants [109,113].…”

Petroleum hydrocarbons and toxic metals are sources of environmental contamination and are harmful to all ecosystems. Fungi have metabolic and morphological plasticity that turn them into potential prototypes for technological development in biological remediation of these contaminants due to their ability to interact with a specific contaminant and/or produced metabolites. Although fungal bioinoculants producing enzymes, biosurfactants, polymers, pigments and organic acids have potential to be protagonists in mycoremediation of hydrocarbons and toxic metals, they can still be only adjuvants together with bacteria, microalgae, plants or animals in such processes. However, the sudden accelerated development of emerging technologies related to the use of potential fungal bioproducts such as bioinoculants, enzymes and biosurfactants in the remediation of these contaminants, has boosted fungal bioprocesses to achieve higher performance and possible real applications. In this review, we explore scientific and technological advances in bioprocesses related to the production and/or application of these potential fungal bioproducts when used in remediation of hydrocarbons and toxic metals from an integral perspective of biotechnological process development. In turn, it sheds light to overcome existing technological limitations or enable new experimental designs in the remediation of these and other emerging contaminants.

Green surfactants–based bioremediation of polycyclic aromatic hydrocarbons (PAHs) from the environment is a promising technique. Rhamnolipids are a class of glycolipid surfactants that belong to the category of green surfactants and have distinctive characteristics. PAHs, which are hazardous toxins, are commonly found in polluted soil, water, and air. PAHs are difficult to break down because they are resistant to degradation and typical methods of cleaning up pollution are not very effective. In recent years, there has been a growing interest in the capacity of specific microorganism species to produce rhamnolipids, which can enhance the process of PAH biodegradation. Rhamnolipids can dissolve and enhance the accessibility of PAHs, thereby boosting the effectiveness of microorganisms that break down PAHs. The presence of rhamnolipids can be attributed to the equilibrium between hydrophobic and hydrophilic properties, as well as their positive charge. Rhamnolipids have biosurfactant properties, making them beneficial for the bioremediation of polluted soil and water. In general, rhamnolipids have proven to be a highly efficient means of removing PAHs from the environment, providing a viable alternative to conventional chemical approaches. Nevertheless, additional investigation is necessary to gain a deeper comprehension of the fundamental principles behind rhamnolipid‐assisted bioremediation and to enhance its implementation in larger real‐world scenarios. This study provides a concise overview of recent research on the utilization of rhamnolipids for bioremediating PAHs in the environment. The article covers the underlying mechanisms, the specific microorganisms employed, and the overall efficacy of the bioremediation process. The utilization of rhamnolipids as a bioremediation tool is examined, along with the difficulties and restrictions of its implementation. The review's conclusion is followed by a discussion on the future directions for studying this topic.
