Synergistic color variants of Aureobasidium pullulans.
Color variants of Aureobasiditlm puliulans were isolated from mao terials collected in tropical and subtropical regions of the world. Three different types of variants produce colonies that are either yellow, red. or purple. When the variants are either mixed with or grown near many different species of yeasts and other microfungi. the rapidity and intensity with which pigment is produced are m...
متن کاملAntibacterial Activity of Aureobasidium Pullulans
Aureobasidium pullulans is ubiquitous, polymorphic and black fungus producing a variety of important metabolites including enzymes, polysaccharides and single cell protein. It is considered as a probable source for antagonistic activity against a number of phytopathogenic fungi and possible biocontrol agent of post harvest diseases. The present work aims at the antibacterial compounds produced ...
متن کاملGenetic transformation of Aureobasidium pullulans.
Aureobasidium pullulans strain Y117 was transformed to hygromycin resistance using plasmid pDH33, which contains the bacterial hygromycin B phosphotransferase gene (hph) fused to promoter elements of the Aspergillus niger glucoamylase gene (glaA). Southern hybridizations of transformants revealed multiple, integrated copies of the vector. The glaA promoter was not induced by starch in A. pullul...
متن کاملEnhanced production of Ca2+-polymalate (PMA) with high molecular mass by Aureobasidium pullulans var. pullulans MCW
BACKGROUND Polymalic acid (PMA) has many applications in food and medical industries. However, so far it has not been commercially produced by fermentation. Therefore, it is very important how to develop an economical process for a large scale production of PMA by one step fermentation. RESULTS After over 200 strains of Aureobasidium spp. isolated from the mangrove systems in the South of Chi...
متن کاملPartial Optimization of Endo-1, 4-Β-Xylanase Production by Aureobasidium pullulans Using Agro-Industrial Residues
UNLABELLED Objective(s) : Although bacteria and molds are the pioneering microorganisms for production of many enzymes, yet yeasts provide safe and reliable sources of enzymes with applications in food and feed. MATERIALS AND METHODS Single xylanase producer yeast was isolated from plant residues based on formation of transparent halo zones on xylan agar plates. The isolate showed much greate...
