“…Continuous cultivation of microorganisms is one of the growing methodologies [108] and is mainly characterized by the constant growth rate of the microorganism in a constant environment (parameters such as pH, substrate concentrations, metabolic products, and oxygen are all constant) [6]. Continuous culture of microbes is carried out in bioreactors called chemostats, a type of bioreactor to which the prepared substrate is constantly supplied, while the culture liquid comprising the remaining nutrients, the end products, and the microbial culture is continuously withdrawn simultaneously to maintain a constant culture volume [109,110].…”

The demand for biosurfactants (BS) produced by yeast for use in industrial processes and products is increasing. Therefore, there has been an increase in the number of publications related to characterization of surfactant compounds produced by yeasts generally recognized as safe (GRAS), which has enabled their application in several industries, including the pharmaceutical and food industries. However, some of these studies use techniques that are not accurate or are no longer essential because of advancements in new technologies. Given the industrial importance of yeasts and their potential to produce BS, this study reviews the production of BS by this microorganism and the most recent industrial applications of BS. It also critically reviews a wide range of techniques used in screening of BS-producing strains, as well as those used in recovery, purification, and characterization of these surfactant compounds produced by yeasts. This review introduces diverse methodologies that are indispensable for the study of BS produced by yeast in an effort to advance BS design, synthesis, and application and introduces new perspectives in the research of these compounds to overcome the obstacles present in this field.

Chemical surfactants have raised concerns due to their negative impact on ecosystems, prompting the search for ecofriendly alternatives. Biosurfactants derived from microorganisms offer a promising solution. These biomolecules are less harmful and can replace toxic pesticide surfactants. Biosurfactants have shown potential in agriculture for food digestion, crop protection, soil fertility, disease management, antibacterial properties, and biofilm prevention. They eliminate plantpathogens and improve nutrient availability, supporting plantgrowth. Rhamnolipids, produced by Pseudomonas, reduce surface tension, are used as wetting agents and emulsifiers in agriculture, and antimicrobial and anti-inflammatory medications. Surfactin, a biosurfactant from Bacillus subtilis, improves plant development, controls plant diseases, and fights pathogens and diseases. Candida bombicola yeast produces sopho-rolipids, biodegradable surfactants with antibacterial, anticancer, and anti-inflammatory properties. Pseudozyma yeast produces mannosylerythritol lipids (MELs), which biocontrol fungus and have antibacterial, anticancer, and immunomodulatory activities. Biosurfactants also hold potential in pharmaceuticals, functioning as antioxidants, exhibiting antibacterial and anticancer activities, and acting as drug-delivery systems. However, challenges in biosurfactant production include varying research methods, limited production organism sources, and cost implications for large-scale manufacturing. This minireview explores microbiologically produced biosurfactants, their regulatory parameters, their applications in optimizing soil health and controlling plant infections, and their potential roles in the pharmaceutical sector.* Ability to tolerate high temperatures, * Ability to tolerate variation in pH, * Ability to tolerate saline environment, * Biodegradable character, * Low or non-toxic nature, and * Effective selectivity.Generally, biosurfactants are amphipathic molecules characterized by hydrophobic and hydrophilic components. Generally, the hydrophobic component consists of a very long chain of fatty acids connected. The hydrophilic component comprises positively, negatively, or amphoterically charged ions. In contrast to their chemical analogs, biosurfactants are often categorized by their CMC concentration, low or high molecular weight, the microorganism type that produce biosurfactant, and their mode of action. Low molecular weight biosurfactants are most frequently reported as glycolipids, phospholipids, and [a]

“…Biosurfactants derived from microorganisms have lately been recognized as multifunctional biomolecules (Santos et al 2016). They are better alternatives to chemical surfactants since they are less harmful to the environment, and they also work better in extreme situations (i.e., temperature, pH, salinity, and so on) (Karnwal 2021). The physiochemical traits of biosurfactants are delineated by their low micellar concentration and ionic strength.…”

Microbial biosurfactants are sustainable alternatives for synthetic counterparts, and display high biodegradability, environmental compatibility, and high selectivity. While previous reports have focussed on production yield, little attention has been paid on downstream processing of biosurfactants, a critical step that controls quality. Here we review methods for biosurfactant downstream processing with focus on glycolipids and lipopeptidesglycolipids and lipopeptides. Solvent extraction, foam fractionation, and sweep floc coagulation allow to reach a purity of 55-70%. While distillation can be implemented prematurely, methods like ultrafiltration and chromatography are used as final processing to recover 90-95% of biosurfactant with 78-95% of purity. We present the cheapest and most efficient downstream techniques for industries to achieve acceptable product quality. This paper puts forth the environmental applications of biosurfactants. We review applications in treating hydrophobic organic pollutants and heavy metals in soils and water. The removal efficiency of biosurfactants reaches 96%. Biosurfactants in the detergent industry, microbial enhanced oil recovery, and soil washing are also discussed.
