Although the presence of tartrate in the growth medium did not affect the synthesis of an extracellular polymer containing 2-acetamido-2-deoxy-D-galacto-pyranosyl residues by A. parasiticus, the acetyl content of the polymer decreased, due, possibly, to the production of an acetylase. Treatment of Aureobasidium pullulans with ethidium bromide produced several mutant strains, which, on culturing, formed a high proportion of yeast-like cells. Comparison of several mutant strains with the wild-type strain suggested that the yeast-like cells are responsible for the synthesis of pullulan.

The strongest known producer of j8-poly(L-malic acid) has been identified as Aureobasidium sp. providing 61 g of polymer from 1 liter of culture medium [5,6]. 8-Poly(L-malate, Ca -salt) of the culture broth was first separated from accompanying bulk pullulan by methanol precipitation. The water-redisolved precipitate was converted to the polymer acid by passage over Amberlite IR-120B (H -form). Thus, the best to-day producers of...
