Using barcoded pyrosequencing fungal and bacterial communities associated with grape berry clusters (Vitis vinifera L.) obtained from conventional, organic and biodynamic vineyard plots were investigated in two subsequent years at different stages during berry ripening. The four most abundant operational taxonomic units (OTUs) based on fungal ITS data were Botrytis cinerea, Cladosporium spp., A...

Abstract Several Aureobasidium spp. strains isolated from wild environments during winter 2022 were characterized by sequence analysis of the internal transcribed spacer (ITS), translation elongation factor EF-1α gene (EF1), and part elongase (ELO). The variability in EF1 ELO loci are higher than ITS. All but one (UC14), identified as A. pullulans . To assess effectiveness biocontrol agents (BC...

In organic phytosanitary management of vineyards, it is crucial to understand the available pathogen control alternatives in order progress towards a more sustainable form viticulture. The objective this study was evaluate efficacy seven biofungicides registered Chile for prevention and treatment Botrytis Bunch Rot (BBR), test novel fungicide composed chitosan riboflavin (CH-RF). Biofungicides ...

Endophytic fungi are beneficial fungi to their host plants and help them to endure biotic and abiotic stresses with different methods. In order to identify some endophytic fungi of sour cherry trees, healthy plant samples including twigs and leaves were collected from several provinces of Iran. A total number of 176 isolates were obtained and studied taxonomically. Based on morphological featur...

Post transplant patients are more vulnerable to the opportunistic fungal infections secondary long -standing treatment on immunosuppressive therapy. A conscientious look in post renal transplant patients view of any is crucial. Aureobasidium pullulans an agent responsible for various pathologies leading nodules with ulceration on skin and systemic infection abcess formation viscera. Keyw...

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...

A total of 40 fungal cultures were isolated for their ability to grow on caffeine as a sole source carbon and nitrogen, and further screened for theophylline-producing activities under the growing cell system. Based on thin-layer chromatography and high-performance liquid chromatography analyses, the potent strain Aureobasidium sp. TeO12 was chosen for its capability to generate theophylline vi...

Multiple tolerance to stressful environmental conditions of the black, yeast-like fungus Aureobasidium pullulans is achieved through different adaptations, among which there is the restructuring of the lipid composition of their membranes. Here, we describe three novel genes encoding fatty-acid-modifying enzymes in A. pullulans, along with the levels of their mRNAs under different salinity cond...

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 organelles-ma...

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 ...
