“…According to Sarachat et al [41], large volumes of drained fermented broth result in a wet foam with low biosurfactant removal as 1.00 vvm (EI 24 = 65.5%), and lower aeration rate increases the residence time of the bubbles, which move slowly up to the top to generate more dried foam and higher enrichment of biosurfactant (0.25 vvm − EI 24 = 67.6%). Santos et al [42] optimized the production of biosurfactant from B. subtilis in an orbital shaker using pineapple waste, and reported an EI 24 of 58.60 below that found in this work. Productivity reached a maximum value of 623.6 % mL h −1 after 10 h of processing, and was followed, at an inversely proportional rate, by the conversion of biomass into the product, since biomass increases with aeration as previously discussed.…”

Biosurfactants are surface-active molecules, produced by several microorganisms, that possess unique properties such as low toxicity and biodegradability. Their application in various industries depends on their purity and their specific properties, such as emulsification and stability. Therefore, this study focuses on the production of biosurfactant from Bacillus atrophaeus in an air-lift bioreactor. It analyzes the effects of agitation rate and temperature on biosurfactant production, as well as the concurrent separation process using a foam fractionation column. Moreover, the ability of the produced biosurfactant to form emulsions in water with several substrates (vegetables oils, hydrocarbons, and fossil fuels) was determined, and the stability of the soybean oil–water emulsion (used as an example) at different temperatures and pH values was verified. The biosurfactant produced, tentatively identified as iturin, was only detected in the coalescent liquid after passing through the foam fractionation column, demonstrating the complete separation of the biosurfactant. The best operational conditions for production and separation were an air flow of 1.00 vvm and a temperature of 34 °C (emulsifier index (EI24) = 66.9%, and productivity (Pp) = 967.5% mL h−1). Vegetable oils, hydrocarbons, and fossil fuels were emulsified in water, highlighting the soybean oil, whose emulsion oil–water had the highest ES (3333.3 min) at a temperature of 50 °C and a pH value of 9.0.

“…They are distinctive secondary metabolites, produced non-ribosomal by certain bacteria, fungi (Ndlovu et al, 2017). They are either integrated into the cell membrane or released extracellularly (El-Shahed et al, 2022;Santos et al, 2023). The amphiphilic structure of a surfactant, consists of a hydrophobic moiety which is either a long-chain fatty-acid, α-alkyl-β-hydroxy fatty acid or hydroxyl fatty acid and the hydrophilic moiety can be a carbohydrate, a peptide, an amino acid, a phosphate group, a carboxylic acid, or alcohol, among others (Rufino et al, 2008;Mandal et al, 2013).…”

B IOSURFACTANTS are active secondary metabolites producing` by certain microorganisms that have the ability to reduce surface and interfacial tension. They have numerous advantages, such as high biodegradability, increased foaming, low toxicity and performance under challenging conditions. Current study was compared between the potential production of biosurfactant by A. carneus OQ152507, A. niger OQ195934 and A. fumigatus OQ195264 using solid state fermentation (SSF) as a low-cost alternative technology. These isolates were cultivated under SSF using different eight agricultural wastes to produce biosurfactants. The optimized bioprocess conditions for the maximum biosurfactant productivity were potato peels waste (20g/l) as a carbon source at 35ºC and pH 7 in glucose peptone medium for A. carneus OQ152507, sun flower seed shells (28g/l) at 35ºC and pH 7 in starch nitrate medium for A. niger OQ195934 and tea wastes (20g/l) at 30ºC and pH 6 in glucose peptone medium for A. fumigatus OQ195264. Their stability was observed at 120°C, 30g/l of NaCl and alkaline pH 10 for A. carneus and pH9 for A. niger and A. fumigatus biosurfactants. The biosurfactants were identified as glycolipid and phospholipids molecules by Phenol-H 2 SO 4 and phosphate test. GC-MS and FT-IR analysis confirmed that the tested fungi participate in producing three hydrophobic fatty acid chains: Cis-Vaccenic acid, n-Hexadecanoic acid and Hexadecanoic acid 2-hydroxy-1 (hydroxymethyl) ethyl ester in distinct peaks with the highest percentage area. While, each one has at least one specific biosurfactant moiety.
