Screening and isolation of the liamocin-producing yeast Aureobasidium melanogenum using xylose as the sole carbon source.

Xylose, the main component of xylan, is the second most abundant sugar in nature after glucose. Consequently, xylose represents an attractive feedstock for the production of value-added compounds such as biosurfactants (BSs), which are produced by various bacteria and yeasts. In this study, we screened and isolated yeast strains that synthesize BSs using xylose as the sole carbon source.
