The thermotolerant yeast strain S1 was identified based on biochemical
characterization by using API Candida strip (bioMérieux®sa, France). The result
which was compared the similarity percentages of sugar acidification and/or enzymatic
reactions patterns with reference strain of the APILAB Plus software (version 2.0) was
demonstrated in Table 4.1.
From the result of API Candida strip, only glucose showed the positive, which
was the characteristic of Candida krusei. Additionally, Candida krusei is considered
to represent the anamorphic form of Issatchenkia orientalis because the type strains
show significant (93-100%) DNA base sequence complementarity (Kurtzman et al.,
1980). It was isolated from a wide variety of habitats including humans and animals
