Microbiological quality of chicken thighs meat after four essential oils combination, EDTA and vaccum packing

<p>The aim of this study was to isolate and identify yeasts in different new wine "federweisser" samples. We collected the samples at the end of the August 2015 and in the middle of the September 2015. Used 15 new wine samples in this study (5 white and 10 red) were from the local Slovak winemakers. Irsai Oliver (3), Moravian Muscat (2), Agria/Turan (1), Dornfelder (3), Blue Frankish (3), Pinot Noir (1) and Saint Laurent (2). Three cultivation media were used for detection of yeasts in "federweisser" samples. Malt extract agar base (MEA), Wort agar (WA) and Wild yeast medium (WYM) were used for the cultivation of yeasts. Cultivation was performed by spread plate method. Ethanol/formic acid extraction procedure was used for preparation of samples. MALDI-TOF Mass Spectrometer (Microflex LT/SH) (Bruker Daltonics, Germany) was used for the identification of yeasts. We identified seven different strains of <em>Saccharomyces cerevisiae </em>(23; 70%), two strains of <em>Kloeckera apiculata </em>[teleomorph <em>Hanseniaspora uvarum</em>]<em> </em>(7; 21%), and one strain of <em>Pichia kluyveri</em> (1; 3%), <em>Pichia occidentalis </em>[anamorph<em> Candida sorbosa</em>]<em> </em>(1; 3%) and<em> Metschnikowia pulcherrima</em> (1; 3%) in 15 new wine "federweisser" samples. <em>Saccharomyces cerevisiae</em> was dominant species in each new wine sample, and formed creamy convex colonies with circular edge. <em>Metschnikowia pulcherrima</em> formed convex to pulvinate, circular white-pink colored colonies,<em> Kloeckera apiculata</em> formed flat, circular smooth colonies with turquoise center with gray edge, <em>Pichia occidentalis</em> formed irregular pulvinate light-cream colored colonies, and <em>Pichia kluyveri</em> formed turquoise, convex, undulate and smooth colonies on Malt extract agar base with bromocresol green.</p> <br /> <!--[endif] -->
