Pullulans produced from the Aureobasidium pullulans fermentation of various agro-industrial wastes were characterised in terms of carbohydrate analysis. heterogeneity and molecular weights. Grape skin pulp extract (GSPE), starch waste (SW), olive oil waste effluents (OW) and molasses (M) were used as substrates for the production of pullulan. A glucose based defined medium (D) was used for comp...

BACKGROUND poly(L-malic acid) (PMA) is a water-soluble polyester with many attractive properties in medicine and food industries, but the high cost of PMA fermentation has restricted its further application for large-scale production. To overcome this problem, PMA production from Jerusalem artichoke tubers was successfully performed. Additionally, a valuable exopolysaccharide, pullulan, was co-...

UEDA, SEINOSUKE (Kyushu University, Fukuoka, Japan), AND HARUYOSHI KONO. Polysaccharide produced by the genus Pullularia. II. Trans-a-glucosidation by acetone cells of Pullularia. Appl. Microbiol. 13:882-885. 1965.-Acetone cells of Pullularia sp. were incubated with maltose, and the saccharides produced were fractionated on a charcoal column. The fractions were subjected to paper-chromatographi...

11 fungi sampled from Quercus acorns with symptoms of black rot and mummification and from necrotic twigs of Q. petraea were tested for pathogenicity towards seedlings of Q. petraea, Q. robur and Q. rubra in a field experiment. Six months after inoculation, necrosis on the main stem and the subsequent death of Q. robur and Q. petraea plants were observed after inoculation with Aureobasidium pul...
