2.2. Identification of yeasts
The isolated yeasts were grouped based on their micro- and
macro-morphological characteristics, following the procedures described
by Yarrow (1998). For each group, a number of isolates
approximately corresponding to the square root of isolates in that
group were identified using API ID 32 C kits (following the instructions
of the manufacturer, BioMerieux, Marcy-L’Etolie, France) and
sequencing of the D1/D2-region of the 26 S rRNA gene, basically
following the protocol of Jespersen, Nielsen, Hønholt, and Jakobsen
(2005).
