Microbiota of Tokaj Grape Berries of Slovak Regions
Bacteria, yeasts and microscopic fungi, which are live and grow normally on the grape surfaces, are important for winemaking. The aim of this study was to investigate the microbiota of the Tokaj wines grapes of Slovak origin. The total bacterial count ranged from 2.48 log cfu/g to 4.52 log cfu/g. Ma...

Summary: | Bacteria, yeasts and microscopic fungi, which are live and grow normally on the grape surfaces, are important for winemaking. The aim of this study was to investigate the microbiota of the Tokaj wines grapes of Slovak origin. The total bacterial count ranged from 2.48 log cfu/g to 4.52 log cfu/g. Malt Extract Agar (MEA) with acid base indicator bromocresol green was used for cultivation of yeast and microscopic fungi and the number of this microorganisms ranged from 1.11 log cfu/g to 4.16 log cfu/g. We found following bacterial species:
Staphylococcus epidermidis, Micrococcus luteus, Paenibacillus pasadenensis
and
Sphingomonas
sp. Identified yeasts species included
Candida sorbose, Kloeckera apiculata, Metschnikowia pulcherrima, Rhodotorula glutinis, Rhodotorula mucilaginosa
and
Saccharomyces cerevisiae
. From microscopic fungi were isolated:
Alternaria
sp.,
Arthrinium
sp.,
Aspergillus niger, Aureobasidium pullulans, Botrytis cinerea, Cladosporium
sp.,
Eurotium
sp.,
Geotrichum candidum, Penicillium expansum, Penicillium
sp. and
Rhizopus
sp. The most dominant species of Tokaj grape were
Kloeckera apiculata
and
Metchnikowia pulcherrima. |
