AUREOBASIDIUM-PULLULANS CAN UTILIZE SIMPLE AROMATIC-COMPOUNDS AS A SOLE SOURCE OF CARBON IN LIQUID CULTURE

Ferulic acid acted as an adequate sole carbon source for Aureobasidium pullulans isolate 105 in liquid culture. A corresponding depletion of ferulate, indicated by depression of the culture filtrate's absorbanc e at 280 nm, was observed over 4 weeks of incubation. Growth of isolat e 105 and six other isolates of A. pullulans was also observed on thre e other aromatic compounds, catechol, protocatechuic acid and vanillic acid. However, none of the isolates grew on dioxane lignin. These res ults may contribute to a better understanding of the way in which A. p ullulans colonizes painted wooden surfaces.
