Biochemical similarities among strains ofAureobasidium pullulans (de Bary) Arnaud

Abstract

Seventy-seven properties of Aureobasidium pullulans including utilization of various carbon sources, decomposition of the lignin-cellulose complex and the respective enzymes were checked in the present communication. According to these properties the group of 43 strains was separated in three parts, out of which two groups were found to belong to varieties A. pullulans var. pullulans and A. pullulans var. melanigenum. The third group formed a marginal part. The two varieties differed in numerous biochemical markers, particularly in the absence of monophenol monooxygenase in the variety A. pullulans var. pullulans.

β‐poly(l‐malic acid) production by fed‐batch culture of Aureobasidium pullulans ipe‐1 with mixed sugars

“…Recent work by Manitchotpisit et al reported that most strains of A. pullulans in genetically diverse phylogenetic clades could produce PMLA. Ĉernáková et al found that A. pullulans could utilize a wide variety of carbon sources, such as d ‐xylose, lactose, sucrose, maltose, cellobiose, inulin, soluble starch, nonglycosidic substrates, etc. So far, there have been very limited publications available regarding the effects of carbon sources on PMLA production in flask , and the mechanism of carbon source on PMLA production was not explained.…”
