a Morphological identification of Pichia fermentans by microscopy. b Phylogenetic tree based on 26s rRNA sequence, using neighbor joining method clustered with bootstrap test with 1000 replicates. The isolated strain reported in the present study is marked with a star. Time-course profiles for shake flask cultivation of P. fermentans on; c xylose and d xylose + glucose. Symbols: filled square (glucose), filled circle (xylose), filled triangle (OD600), empty circle (xylitol) and filled star (pH). The graphs represent the average values of triplicate experiments performed with less than 10% S.D (standard deviation)
