Antibacterial 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 کاملIDENTIFICATION, ISOLATION, CLONING AND SEQUENCING APARTIALANNEXIN GENE FROM AUREOBASIDIUM PULLULANS
Background and Objectives: Annexin is the common name for genes and proteins that were identified as calcium-dependent phospholipid-binding proteins. Recently a more complex set of functions has been recognized for this superfamily of proteins including in vesicle trafficking, cell division, apoptosis, calcium signalling, mineralization, crystal nucleation inside the extracellular organelle...
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 کاملRedefinition of Aureobasidium pullulans and its varieties
Using media with low water activity, a large numbers of aureobasidium-like black yeasts were isolated from glacial and subglacial ice of three polythermal glaciers from the coastal Arctic environment of Kongsfjorden (Svalbard, Spitsbergen), as well as from adjacent sea water, sea ice and glacial meltwaters. To characterise the genetic variability of Aureobasidium pullulans strains originating f...
متن کاملPartial Purification and Characterization of Fructosyltransferase from Aureobasidium Pullulans
Fructosyltransferase enzymes was isolated and partially purified from Aureobasidium pullulans. The enzyme being intracellular was recovered from the fungal sp. by extraction method using citrate buffer (0.1 M; pH 5.5). Enzyme was Semipurified by salt fractionation method which results increase in specific activity of the enzyme. Study regarding kinetic behavior indicates that the enzyme exhibit...
