“…Antagonism of microorganisms by yeasts has been attributed primarily to (1) competition for nutrients, (2) pH changes in the medium as a result of growth-coupled ion exchange or organic acid production, (3) production of high concentrations of ethanol, (4) secretion of antibacterial compounds and release of antimicrobial compounds such as killer toxins or “mycocins” (Suzuki et al, 2001; Golubev, 2006; Young and Yagiu, 1978). Mycocins are extracellular proteins or glycoproteins that disrupt cell membrane function in susceptible yeasts, which bear receptors for the compound (Golubev, 2006).…”

“…Several have since been isolated, frequently where yeast populations exist in high density and in highly competitive conditions. Mycocin production occurs among many yeast genera including Saccharomyces , Candida , Cryptococcus , Debaryomyces , Kluyveromyces , Pichia , Torulopsis , Williopsis , and Zygosaccharomyces (Young and Yagiu, 1978; Magliani et al, 1997; Chen et al, 2000; Schmitt and Breinig, 2002; Golubev, 2006; Hodgson et al, 1995). Genetic and molecular studies have shown that the killer toxin trait may be carried on extra-chromosomal elements in the form of double-stranded RNA viruses (Wickner, 1996), on double-stranded linear DNA (Gunge et al, 1981; Hayman and Bolen, 1991), or on a chromosome (Kimura et al, 1993; Suzuki and Shimma, 1999).…”

The yeasts constitute a large and heterogeneous group of microorganisms that are currently attracting increased attention from scientists and industry. Numerous and diverse biological activities make them promising candidates for a wide range of applications not limited to the food sector. In addition to their major contribution to flavor development in fermented foods, their antagonistic activities toward undesirable bacteria, and fungi are now widely known. These activities are associated with their competitiveness for nutrients, acidification of their growth medium, their tolerance of high concentrations of ethanol, and release of antimicrobial compounds such as antifungal killer toxins or “mycocins” and antibacterial compounds. While the design of foods containing probiotics (microorganisms that confer health benefits) has focused primarily on Lactobacillus and Bifidobacterium, the yeast Saccharomyces cerevisiae var. boulardii has long been known effective for treating gastroenteritis. In this review, the antimicrobial activities of yeasts are examined. Mechanisms underlying this antagonistic activity as well as recent applications of these biologically active yeasts in both the medical and veterinary sectors are described.

“…None of these isolates was sensitive to mycocins produced by representatives of the genera Cryptococcus, Cystofilobasidium Oberwinkler et Bandoni, Filobasidium Olive, Rhodotorula and Sporidiobolus Nyland, while it has been known that mycocins are active against species phylogenetically related to mycocinogenic strains (Golubev, 2006).

A distinguishing feature of the majority of the tremellomycetous yeasts is their ability to utilize a cyclitol, myoinositol, as sole source of carbon and energy. This characteristic, which, as a rule, is not shared by ascomycetous yeasts and by basidiomycetous yeasts of other classes, represents a fundamental key in yeast identification. Specifically, inositol assimilation is a criterion used to distinguish between anamorphic yeasts of the genera Cryptococcus Vuillemin and Rhodotorula Harrison (Kurtzman & Fell, 1998;Barnett et al., 2000). With a few exceptions, species of the genus Cryptococcus (subphylum Agaricomycotina) utilize both myo-inositol and D-glucuronate, the first intermediate of inositol catabolism, whereas species belonging to the genus Rhodotorula typically do not assimilate myo-inositol, and D-glucuronate assimilation is variable within this genus. Eukaryotes metabolize myoinositol via the D-glucuronate-L-gulonate pathway (Golubev, 1989), i.e. the sole step only, the oxidation of myo-inositol to D-glucuronate, is absent in D-glucuronatepositive but myo-inositol-negative Rhodotorula species. During a survey of yeasts from pine and spruce dead needle litters we found several isolates that were positive for both myo-inositol and D-glucuronate assimilation. A rDNA gene sequence analysis and a comparison of their phenotypic properties revealed that the isolates constitute novel anamorphic species in the Microbotryomycetes, for which the names Rhodotorula rosulata sp. nov., Rhodotorula silvestris sp. nov. and Rhodotorula straminea sp. nov. are proposed.The strains (isolation numbers: Pa-78, Pa-84, Pa-85, Ps-88, Ps-93, Ps-103, Ps-128 and Ps-130) were isolated from dead Abbreviation: ITS, internal transcribed spacer.The GenBank/EMBL/DDBJ accession numbers for the LSU rDNA gene D1/D2 domain sequences determined in this study are EU872490, GQ121044 and EU872489. Accession numbers for the ITS region sequences are EU872492, GQ121045 and EU872491.Phylogenetic trees based on sequence analysis of the D1/D2 domains of the LSU rDNA gene and the ITS regions are available with the online version of this paper.

“…They possess multiple biological activities: they act as biosurfactants, facilitate dissolution and consumption of organic hydrophobic compounds, and display fungicidal activity (Kitamoto et al 2002; Cameotra and Makkar 2004; Golubev 2006; Rodrigues et al 2007). Cellobiose lipids display antifungal activity against many species of ascomycetous and basidiomycetous yeast and mycelial fungi including know pathogens, Filobasidiella (Cryptococcus) neoformans and Candida albicans (Puchkov et al 2002; Kulakovskaya et al 20052009; Mimee et al 2005; Bölker et al .…”

The antifungal effect of cellobiose lipid on the cells of Saccharomyces cerevisiae depends on carbon source

The cellobiose lipid of Cryptococcus humicola, 16-(tetra-O-acetyl-β-cellobiosyloxy)-2-hydroxyhexadecanoic acid, is a natural fungicide. Sensitivity of the cells of Saccharomyces cerevisiae to the fungicide depends on a carbon source. Cellobiose lipid concentrations inducing the leakage of potassium ions and ATP were similar for the cells grown in the medium with glucose and ethanol. However, the cells grown on glucose and ethanol died at 0.05 mg ml-1 and 0.2 mg ml-1 cellobiose lipid, respectively. Inorganic polyphosphate (PolyP) synthesis was 65% of the control with 0.05 mg ml-1 cellobiose lipid during cultivation on ethanol. PolyP synthesis was not observed during the cultivation on glucose at the same cellobiose lipid concentration. The content of longer-chain polyP was higher during cultivation on ethanol. We speculate the long-chained polyP participate in the viability restoring of ethanol-grown cells after treatment with the cellobiose lipid.
