“…Biosurfactants are synthesized by a wide variety of microorganisms, mainly by bacteria and several yeasts . Lipopeptides are among the most studied bioactive molecules, produced by multiple bacterial genera such as Bacillus , Paenibacillus , Pontibacter , Achromobacter , Corynebacterium , Pseudomonas , Streptomyces , Citrobacter , and Enterobacter …”

In this work, the extraction, structural analysis, and identification as well as antimicrobial, anti‐adhesive, and antibiofilm activities of lipopeptides produced by Enterobacter cloacae C3 strain were studied. A combination of chromatographic and spectroscopic techniques offers opportunities for a better characterization of the biosurfactant structure. Thin layer chromatography (TLC) and HPLC for amino acid composition determination are used. Efficient spectroscopic techniques have been utilized for investigations on the biochemical structure of biosurfactants, such as Fourier transform infrared (FT‐IR) spectroscopy and mass spectrometry analysis. This is the first work describing the production of different isoforms belonging to kurstakin and surfactin families by E cloacae strain. Three kurstakin homologues differing by the fatty acid chain length from C10 to C12 were detected. The spectrum of lipopeptides belonging to surfactin family contains various isoforms differing by the fatty acid chain length as well as the amino acids at positions four and seven. Lipopeptide C3 extract exhibited important antibacterial activity against Gram‐positive and Gram‐negative bacteria, antifungal activity, and interesting anti‐adhesive and disruptive properties against biofilm formation by human pathogenic bacterial strains: Salmonella typhimurium, Klebsiella pneumoniae, Staphylococcus aureus, Bacillus cereus, and Candida albicans.

“…To be a powerful genus involved in bioremediation of crude-oilcontaminated environment, many Achromobacter strains were isolated and identified (Ghevariya et al, 2011;Deng et al, 2016;Hou et al, 2018;Haloi and Medhi, 2019). Understanding the optimum growth conditions of the bacteria is beneficial to the application of the strains.…”

“…The adsorption of surfactants is related to their structure; hence, they are used for emulsifying, solubilising, dispersing, condensing, cleaning, absorbing moisture, permeating, foaming and lubricating. Researchers have developed and characterised surfactants with different properties, from traditional synthetic surfactants, to more recent biosurfactants (Van Bogaert et al, 2007;Daverey and Pakshirajan, 2009;Olkowska et al, 2014;Deng et al, 2016).…”

SummaryHorse oil contains linoleic, palmitoleic and unsaturated fatty acids that are similar to those in human skin, and may therefore be an ideal substance from which to isolate biosurfactants for cosmetic products to improve human skin quality. Herein, an innovative approach was developed to synthesise sophorolipids from horse oil by hydrolysis, followed by fermentation using the yeast Candida bombicola. The yield of sophorolipids from direct fermentation of horse oil and hydrolysed horse oil was 40.6 ± 1.3 g l−1 and 58.4 ± 1.8 g l−1 respectively. To further increase the yield, 30–40 g l−1 glucose was added in a fed‐batch fermentation process to maintain the pH between 4.0 and 4.5, resulting in a conversion yield of 71.7 ± 0.8 g l−1. The purity and structure of the synthesised sophorolipids were analysed by ultra‐performance liquid chromatography‐mass spectrometry and nuclear magnetic resonance. An in vitro human dermal fibroblast model was used as a surrogate for human skin to measure elastase inhibition activity. Antiwrinkle properties of isolated sophorolipids were better than those of horse oil or hydrolysed horse oil in several in vitro assays. Furthermore, no cytotoxicity was observed at a concentration of 50 μg ml−1, and wound‐healing capacity was evident in a cell culture model. Additionally, the synthesised sophorolipids attenuated lipopolysaccharide‐induced expression of inflammatory cytokines in macrophages, and efficiently inhibited several strains of bacteria and yeast. In conclusion, fed‐batch fermentation of hydrolysed horse oil is a novel and efficient approach for producing high‐quality and high‐yield sophorolipids that exhibit great potential as cosmetic ingredients.
