This study set out to isolate and identify epiphytic yeasts producing pulcherrimin, and to evaluate their potential as biological control agents (BCAs). We isolated Metschnikowia sp. strains from flowers and fruits collected in Poland. The plant material had been collected between April to September 2017 from two small orchards where traditional organic management is employed. We identified the essential phenotypic features of the yeast, including assimilation and enzymatic profiles, stress… 
New Isolated Metschnikowia pulcherrima Strains from Apples for Postharvest Biocontrol of Penicillium expansum and Patulin Accumulation
The results shown that this yeast strain could be used for the reduction of P. expansum and its mycotoxin in apples or apple-based products by adapting the procedure application are shown.
The antagonistic Metschnikowia andauensis produces extracellular enzymes and pulcherrimin, whose production can be promoted by the culture factors
The results suggest that other mechanisms besides the iron depletion of the culture media may contribute to the antagonistic capacity of M. andauensis and suggest that biological control against microbial infections has a great potential as an alternative approach instead of fungicidal chemicals.
Metschnikowia pulcherrima and Related Pulcherrimin-Producing Yeasts: Fuzzy Species Boundaries and Complex Antimicrobial Antagonism
Recent results of research into the complexity of the taxonomic division of the pulcherrimin-producing Metschnikowia yeasts and the mechanism(s) underlying their antimicrobial antagonism are discussed in this review.
The Oleaginous Yeast Metschnikowia pulcherrima Displays Killer Activity against Avian-Derived Pathogenic Bacteria
The potential of an otherwise-useful industrial yeast, Metschnikowia pulcherrima, for the active suppression of poultry pathogenic bacteria is investigated, finding that the more inhibitory strains of yeast supressed bacterial growth and actively killed the most recalcitrant bacteria.
Lysates of Metschnikowia yeast with higher content of hydroxyproline
The chemical characteristics of lysates obtained from yeasts belonging to Metschnikowia spp. were determined. Cell lysis was induced using saponin from Q. saponaria or 5% NaCl. The process was
Analyzing Ash Leaf-Colonizing Fungal Communities for Their Biological Control of Hymenoscyphus fraxineus
The invasive ascomycete Hymenoscyphus fraxineus has been threatening Fraxinus excelsior populations throughout Europe for over two decades and leaf-colonizing microorganisms have been discussed as a barrier and as possible biocontrol agents against the disease.
Stability of Dry and Liquid Metschnikowia pulcherrima Formulations for Biocontrol Applications against Apple Postharvest Diseases
The yeast Metschnikowia pulcherrima is frequently isolated from environmental samples and has often been reported to exhibit strong antagonistic activity against plant pathogens. In order to assess

It was shown that all three strains of M. pulcherrima produce the same amount of the pigment Pulcherrimin, but their antimicrobial activities on different microorganisms show important variations, and their antagonistic effects on these fungal species at different extents.
Potential Role of Yeast Strains Isolated from Grapes in the Production of Taurasi DOCG
Nine strains of Saccharomyces cerevisiae were characterized for ethanol production, SO2 resistance, H2S development, β-glucosidasic, esterasic and antagonistic activities, andFermentation abilities of selected strains were evaluated in micro-fermentations on Aglianico must.
Molecular and Phenotypic Characterization of Metschnikowia pulcherrima Strains from Douro Wine Region
M. pulcherrima proved to be promising for future industrial application as a co-starter, lowering ethanol, acetic acid and, reported here for the first time, lowering hydrogen sulfide levels in the wines.
Characterization of a novel yeast species Metschnikowia persimmonesis KCTC 12991BP (KIOM G15050 type strain) isolated from a medicinal plant, Korean persimmon calyx (Diospyros kaki Thumb)
It is concluded that this yeast isolate from D. kaki is a new member of the genus Metschnikowia and proposed the name M. persimmonesis sp.
Yeasts from Different Habitats and Their Potential as Biocontrol Agents
The majority of yeasts were found to interfere with fungi infecting grapevine, stone fruits, or rice, as well in vitro and in model experiment on fruits, and attempts to demonstrate direct antagonistic activities of lytic enzymes failed.
Candida ecuadorensis sp. nov., an ascomycetous yeast species found in two separate regions of Ecuador.
Phylogenetic analysis revealed this novel species to belong to the Metschnikowia clade and to be most closely related to Candida suratensis, a species recently discovered in a mangrove forest in Thailand.
Biocontrol Activity of the Local Strain of Metschnikowia pulcherrima on Different Postharvest Pathogens
M. pulcherrima UMY15 can be used as a very effective biocontrol yeast against various species of postharvest pathogens, including Penicillium, Aspergillus, Fusarium, and Rhizopus.
Yeast Diversity and Persistence in Botrytis-Affected Wine Fermentations
Analysis of wine fermentation microbial ecology by using both culture-dependent and -independent methods reveals the complexity of yeast interactions enriched during spontaneous fermentations.
