The physicochemical properties and chemical composition of trehalose lipids produced by Rhodococcus erythropolis 51T7

Production and applications of trehalose lipid biosurfactants

“…However, this study used positive ionisation mode which can become very complex due to the presence of both protonated ions along with sodium adducts. Therefore, ESI-MS in negative ion mode would be a better alternative and this was demonstrated in a recent publication using HPLC-MS [44]. NMR can also be used for characterisation of trehalose lipids either intact or after hydrolysis.…”

“…To date there have been very few studies carried out to confirm their lack of toxicity. For example, Marques et al [44] assayed potential skin irritation of trehalose lipids produced by R. erythropolis 51T7 with mouse fibroblast and human keratinocyte lines. Their results indicated that the biosurfactant is less irritating than SDS, and could be therefore used in cosmetic preparations.…”

“…The most commonly used solvent system for efficient extraction is chloroform:methanol (2:1) [43], while methyl tert Trehalose lipids n-hexadecane Cell-bound [31] butyl ether (MTBE) [29] and more recently a mixture of ethyl acetate:methanol (8:1) has been shown to be a suitable solvent for extraction [44]. Acid precipitation, similar to that of rhamnolipids and surfactin has been described by Uchida et al [18] for mono and di-succinoyl trehalolipids.…”

Rhamnolipids as emulsifying agents for essential oil formulations: Antimicrobial effect against Candida albicans and methicillin-resistant Staphylococcus aureus

“…Despite the fact that the phase behaviour of water/surfactant/ oil systems at constant temperatures has been studied extensively for pharmaceutical and cosmetic formulations (Attwood and Florence, 1983), and for agricultural and food applications, the literature provides little information on phase diagrams with biosurfactants Kitamoto et al, 2009;Marqués et al, 2009;Torrego-Solana et al, 2014).…”

Glycolipid biosurfactants: Potential related biomedical and biotechnological applications

“…[12][13][14] Owing their natural origins, they are recognized as low or non-toxic. [15][16][17][18][19][20] Also, they well known by a good biodegradability [21][22][23] encouraging their use as alternatives to synthetic surfactants. So, they have the potential to be used in environmental field as enhancing of hydrocarbons solubility, mobility and biodegradation.…”
