| Résumé : |
Bio-based surfactants and biosurfactants on the basis of renewable resources are green alternatives for the cosmetic and detergent industry. Consumer trends towards sustainability and the need for CO2, reduction to achieve future climate goals wifl certainly increase interest in these bio-based products. Opportunities for biotechnological production by Combining naturally derived polar head groups with a lipid tail are manifold. In combination with appropriate reaction engineering immobilized hydrolases can be exploited for surfactant synthesis. In their reverse reactions, glycosidases are able to form glyosidic bonds, aùinoacylases were shown to catalyze amide bond formation and several lipases synthesize sugar esters in solvent systems under nearly water free conditions. The microbial synthesis of natural biosurfactants widens the spectrum of accessible molecules and several species of bacteria and fungi were shown to secrete amphiphilic molecules not easily accessible by chemical synthesis. The fermentative production of lipopeptides and glycolipids is feasible in large scale, and several of these microbial biosurfactants have been commercialized already for specialties application. Thus, biocatalytic processes and microbial biotransformations utilizing renewable resources add new sustainable technologies and new bio-based molecules to the surfactant market.
The review, including some own results, is a summary of the 2016 EDC congress lectures "Assessment of biotechnological processes towards bio-based surfactants" and "Microbial synthesis of mannosylerythritol- and cellobioselipids" |
