ABSTRACT:
A method for obtaining a substantially biologically pure culture strain of Aureobasidium pullulans from a wild type strain by enriching the collected strain for organisms which grow as fungal yeastlike cells, growing colonies from isolated yeastlike cells and selecting those yeastlike cells which exhibit reduced pigmentation. Biologically pure culture strains obtained by the invention as well as methods for producing pullulan having decreased pigmentation and/or increased molecular weight are disclosed.
