“…This difference was very clear in their effects on the growth of the various strains of C. albicans. Differential antagonistic effects of M. pulcherrima strains on the Aspergillus and Penicillium species were reported previously (Janisiewicz et al, 2001;Bleve et al, 2006).…”

Metschnikowia pulcherrima is a highly effective biocontrol yeast due to its pigment pulcherrimin that accumulates in the cells and in the growth medium. Three different strains of M. pulcherrima were isolated from local grapes. The yeast isolates were characterized on the basis of their biochemical, physiological and ITS1-5.8 s rDNA-ITS2 region. Based on the obtained results, the M. pulcherrima isolates were identifi ed as new strains of M. pulcherrima. Strong antagonistic activities of the M. pulcherrima strains on the human pathogens Proteus vulgaris, Escherichia coli, Candida albicans, Candida parapsilosis, Candida krusei, and Trichosporon mucoides were determined. In addition, antagonistic effects of these M. pulcherrima strains were also tested against Aspergillus fl avus, Aspergillus fumigatus, Aspergillus niger, Trichoderma spp., Paecilomyces spp., and Bipolaris spp. and it was shown that the three different strains of M. pulcherrima also have an antagonistic effect on the growth of these fungal species at different extents. This study showed 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.

“…The efficiency of the inhibition effect was dependent on the strain (i.e., both cell concentrations were effective). Thus, for some yeast strains (e.g., D. polymorphus CCMA 0143, Pichia burtonii CCMA 0149, P. kluyveri CCMA 0165, R. mucilaginosa CCMA 0154), the action mechanism is not nutrient or space competition, as reported by Bleve, Grieco, Cozzi, Logrieco, and Visconti (2006), Masoud and Kaltoft (2006) and Zhu et al (2015); other mechanisms could include killer toxin production (Banjara, Nickerson, Suhr, & HallenAdams, 2016;Grzegorczyk, Żarowska, Restuccia, & Cirvilleri, 2017), volatile compound production (Núnez et al, 2015) or adsorption to yeast cell walls, as observed in Rhodotorula by Var, Erginkaya, and Kabak (2009) and Debaryomyce shansenii by Gil-Serna et al (2011).…”

<b>Use of wild yeasts as a biocontrol agent against toxigenic fungi and OTA production

ABSTRACT. This study evaluated the antagonistic potential of 32 wild yeast isolates from coffee and cocoa bean fermentation. These yeasts were inoculated in co-cultivation with Aspergillus carbonarius (CCDCA 10608 and CCDCA 10408) and Aspergillus ochraceus (CCDCA 10612) isolated from grapes and coffee beans. The mycelial growth and ochratoxin A (OTA) production were evaluated, and the spores were counted after cultivation at 28°C for seven days. The yeasts presented higher inhibitory effects (53% in relation to the control) over the mycelial growth of the isolated A. ochraceus (CCDCA10612). Pichia anomala CCMA0148 and Saccharomyces cerevisiae CCMA0159 provided the greatest inhibition of the growth of all fungal strains. All Pichia species presented the highest inhibitory effects on the production of spores, and S. cerevisiae CCMA 0159 at concentrations of both 10 4 and 10 7 mL -1 cells inhibited the production of spores by 100%. Rhodotorula mucilaginosa was effective at inhibiting OTA production by the three isolates of Aspergillus. S. cerevisiae CCMA0159 and Pichia anomala CCMA0148 showed high potential as biocontrol agents in the conditions tested.

Wine Contamination with Ochratoxins: A Review

Ochratoxin A (OTA) is the main mycotoxin occurring in wine. This review article is focused on the distribution of this toxin and its producing-fungi in grape berries, as well as on the fate of OTA during winemaking procedures. Due to its toxic properties, OTA levels in wine are regulated in different countries; therefore, it is necessary to apply control and detoxification methods that are also discussed in this revision.
