Moesziomyces antarcticus is an efficient producer of mannosylerythritol lipids (MEL), a biosurfactant with a wide range of potential applications. The use of lignocellulosic biomass can contribute to sustainable MEL production. While lignocellulosic sugars (e.g. D-glucose and D-xylose) can be converted to MEL, the required pretreatment of lignocellulosic biomass releases by products that are potentially inhibitory for yeasts. A recent publication by Marisa Santos, Nuno Faria and Frederico Ferreira from BERG-iBB , in collaboration with César Fonseca from LNEG, describes a design of experiment (DoE) that was performed to evaluate the effect of furfural, acetate and formate on M. antarcticus and its capacity to produce MEL from lignocellulose hydrolysates. The study provides insight into the conditions required by M. antarcticus for MEL production from lignocellulosic hydrolysates and points towards further process and strain development requirements. The work was published in Journal of Chemical Technology and Biotechnology and made it to the cover of the journal.
