“…Mono, di, or polysaccharides, anions, or cations comprise the hydrophilic moiety of biosurfactants. In contrast, the hydrophobic moiety is made up of both saturated and unsaturated fatty acids (Abo Elsoud and Ahmed 2021 ). Glycolipids, the most prevalent form of biosurfactant, are composed of fatty acids and carbohydrates connected by either an ester or an ether group (Mnif et al 2018 ).…”

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.

“…In the current development of novel surfactants, there is a growing trend of utilizing nontraditional naturally occurring branching hydrophobic chains [61][62][63]. Nonionic surfactants based on twin tail glycerol have been synthesized and they have good oil-in-water and water-in-oil emulsifying characteristics [64] structural analogs of glycerol-based surfactants have recently been created by employing heterogeneous interfacial acidic catalysts to directly etherify glycerol and dodecanol.…”

Bio-based surfactants are surface-active compounds derived from oil and fats through the production of oleochemicals or from sugar. Various applications of bio-based surfactants include household detergents, personal care, agricultural chemicals, oilfield chemicals, industrial and institutional cleaning, and others. Due to the stringent environmental regulations imposed by governments around the world on the use of chemicals in detergents, as well as growing consumer awareness of environmental concerns, there has been a strong demand in the market for bio-based surfactants. Bio-based surfactants are recognized as a greener alternative to conventional petrochemical-based surfactants because of their biodegradability and low toxicity. As a result, more research is being done on producing novel biodegradable surfactants, either from renewable resources or through biological processes (bio-catalysis or fermentation). This chapter discusses the various types, feedstocks, and applications of bio-based surfactants, as well as the industrial state-of-the-art and market prospects for bio-based surfactant production. In addition, relevant technological challenges in this field are addressed, and a way forward is proposed.

“…Unlike chemically synthesized surfactants, which are classified according to the nature of their polar group, biosurfactants are categorized mainly by their chemical composition and their microbial origin. In general, their structure includes a hydrophilic moiety consisting of amino acids or peptides, anions or cations; mono-, di-, or polysaccharides; and a hydrophobic moiety consisting of unsaturated and saturated fatty acids (37,38). Glycolipids are the most known biosurfactants.…”

Biosurfactants can be used for bioremediation as amphiphilic compounds that have shown good tolerance to changes in temperature, salt concentration, pH, and other environmental factors. They have received increased attention in bioremediation because they are biodegradable and do not generate any secondary contaminants. Biosurfactants are used to remove organic molecules for example hydrocarbon contaminants through various mechanisms such as surface tension reduction, emulsification, and micelle formation. They can also play a role in removing heavy metals by increasing contact with the surface of heavy metal deposits and forming complexes and micelle formation. In this review, we focus on the role of biosurfactants in improving the efficacy of bioremediation.
