“…Besides that, foam resulting from emulsification of biosurfactants due to vigorous agitation during cultivation might decrease the transfer efficiency of oxygen into the liquid medium [ 17 ] in which countermeasures can be taken to eliminate foaming but will further drive-up the production cost. To overcome these problems, various researchers were looking into cheaper alternative substrates, optimization of the environmental conditions, and improvement on the downstream recovery processes [ 18 , 19 , 20 , 21 ]. Still, no definitive method could contribute to the overall cost saving for biosurfactant production.…”

Culture Medium Development for Microbial-Derived Surfactants Production—An Overview

Surfactants are compounds that can reduce the surface tension between two different phases or the interfacial tension of the liquid between water and oil, possessing both hydrophilic and hydrophobic moieties. Biosurfactants have traits that have proven to be advantageous over synthetic surfactants, but these compounds do not compete economically with synthetic surfactants. Different alternatives increase the yield of biosurfactants; development of an economical production process and the usage of cheaper substrates during process have been employed. One of the solutions relies on the suitable formulation of a production medium by including alternative raw materials sourced from agro-wastes, hydrocarbons, or by-products of a process might help in boosting the biosurfactant production. Since the nutritional factors required will be different among microorganisms, the establishment of a suitable formulation for biosurfactant production will be challenging. The present review describes various nutrients and elements considered in the formulation of a production medium with an approach focusing on the macronutrient (carbon, nitrogen source, and C/N ratio), minerals, vitamins, metabolic regulators, and salinity levels which may aid in the study of biosurfactant production in the future.

“…MELs have possible applications in the petrochemical industry and could be a promising agent for enhanced oil recovery, especially because they maintain stability and activity under extreme temperatures, pH and salt concentration values [87,95]. In addition, MEL-A improves the fluidity of biodiesel and hydrocarbon fuels at low temperatures, opening the possibility for MELs to be applied as fuel additives [85].…”

Mannosylerythritol lipids (MELs), one of the most promising biosurfactants (BS), are glycolipids produced by yeasts or fungi, which have great environmental performance and high compatibility with the human body. MELs, besides working as typical surfactants, can form diverse structures when at or above the critical aggregation concentration (CAC), reduce the surface tension of water and other solutions, and be stable over a wide range of conditions. Among others, MELs present antimicrobial, antitumor, antioxidant and anti-inflammatory activities and skin and hair repair capacity, which opens possibilities for their use in applications from cosmetics and pharmaceutics to bioremediation and agriculture. However, their market share is still low when compared to other glycolipids, due to their less developed production process and higher production cost. This review gathers information on the potential applications of MELs mentioned in the literature since 1993. Furthermore, it also explores the current strategies being developed to enhance the market presence of MELs, in parallel with the ones developed for rhamnolipids and sophorolipids.
