Abstract

The aim of this study was to isolate and identify microscopic fungi in different grape samples. We collected 13 grapes varienties samples (9 white and 4 red) from local Slovak winemakers in the end of the September 2017. Used 13 grape samples in this study: Alibernet, Irsai Oliver, Dornfelder, Blue Frankish, Feteasca regala, Green Veltliner, Pálava, Mūller Thurgau, Rhinriesling, Cabernet Savignon, Pinot Blanc, Savignon Blanc and Welschriesling. Microscopic fungi in grape samples were detected on Malt extract agar by spread plate method. The number of microscopic fungi ranged from 2.85 log cfu.g-1 in Cabernet Savignon to 4.83 log cfu.g-1 in Feteasca regala. A total of 627 isolates of microscopic fungi were obtained in this study. The most abundant fungi belonged to genera Alternaria and Penicillium (100% frequency). The high frequency was also detected for Aspergillus (76.92%) and Cladosporium (76.92%) but with lesser relative density. Alternaria sp., Aspergillus niger, Aspergillus sp., Botrytis cinerea, Cladosporium sp., Penicillium expansum, Phoma sp., Rhizopus sp. and Trichoderma sp. species were isolated from grape berries.
