Pichia anomala and Kluyveromyces wickerhamii killer toxins as new tools against Dekkera/Brettanomyces spoilage yeasts.
Two yeast killer toxins active on spoilage yeasts belonging to the genus Dekkera/Brettanomyces are here described for the first time. The two toxins produced by Pichia anomala (DBVPG 3003) and Kluyveromyces wickerhamii (DBVPG 6077), and named Pikt and Kwkt, respectively, differ for molecular weight and biochemical properties. Interestingly, the fungicidal effect exerted by Pikt and Kwkt against...
متن کاملA Case of Fungal Arthritis Caused by Hansenula Anomala
Hansenula anomala (H. anomaly) is part of the normal flora in the alimentary tract and throat. It has been reported to be an organism causing opportunistic infections in immunocompromised patients. However, cases of fungal arthritis caused by H. anomala are rare. We encountered a case of H. anomala arthritis in a 70-year-old man who was treated with an empirical antibiotic treatment and surgery...
متن کاملPyridine nucleotidenitrate reductase from Hansenula anomala a nitrate reducing yeast.
The recent elucidation of the enzyme systems involved in nitrate reduction in Neurospora crassa (Evans and Nason, 1952; Nason and Evans, 1953); Bacillus pumilis (Taniguchi et al., 1953); Escherichia coli (Taniguchi et al., 1956; Nicholas and Nason, 1955) and higher plants (Evans and Nason, 1953), has renewed interest in the general problem of nitrate reduction and nitrate assimilation in microo...
متن کاملYeast killer toxins and dimorphism.
The differential action of four selected yeast killer toxins on the mycelial and yeast forms of four isolates of the dimorphic fungus Sporothrix schenckii was comparatively evaluated. The results confirmed that the yeast killer phenomenon is present among hyphomycetes and yeasts and that both morphological forms of S. schenckii are susceptible to the action of the same yeast killer toxin. Quant...
متن کاملTransport of malic acid and other dicarboxylic acids in the yeast Hansenula anomala.
DL-Malic acid-grown cells of the yeast Hansenula anomala formed a saturable transport system that mediated accumulative transport of L-malic acid with the following kinetic parameters at pH 5.0: Vmax, 0.20 nmol.s-1.mg (dry weight)-1; Km, 0.076 mM L-malate. Uptake of malic acid was accompanied by proton disappearance from the external medium with rates that followed Michaelis-Menten kinetics as ...
