Although more than 3000 antibiotics have been reported from Actinomycetesl higher
fungi; biotechnological potential of yeasts and yeast-like fungi with respect to production
of antimicrobial compounds has not been sufficiently investigated. We examined the
antimicrobial activity of 11 strains of Aureobasidium pullulans (two new isolates and nine
standard strains). All the strains of Aureobasidium pullulans inhibited Ps. jluorescen s, but
none of these strains could inhibit Candida albicans and S. cerevisiae. Interestingly, the
yeast Pichia angusta was inhibited by six of the A. pullulans strains used in the present
investigation. Two indigenous isolates of Aureobasidium Natural Isolate 1 (N!. 1) and
Natural Isolate 2 (N!. 2) showed antibacterial activity against the Gram-negative cultures;
most of which were resistant to Gentamicin. This study provides evidence that A. pullulans
is a promising producer of antimicrobial agents for better chemotherapeutic agents, possibly
against Pseudomonals infections.
