Results demonstrated differences between the performed tests by VITEK[R]2 and conventional tests with regard to
cellobiose degradation.

In addition, the stp1 exhibited a higher level of expression in sophorose than in cellulose, although it is involved in
cellobiose and glucose transport [21].
Then, 2.5 mL of the culture ([OD.sub.600] = 1.9) was transferred to YPGGC (3.0 g [L.sup.-1] yeast extract, 5.0 g [L.sup.-1] peptone, 20.0 g [L.sup.-1] galactose, 20.0 g [L.sup.-1] glucose and 10.0 g [L.sup.-1]
cellobiose) and cultured under the same conditions.
In the first screening, twenty-three yeast strains were assessed individually for their ability to grow in medium containing CMC, Avicel[R],
cellobiose and xylan from Birchwood (Sigma) as sole carbon sources (Table 1).
all amino acids and a number of sugars, such as trehalose,
cellobiose, maltose, sucrose, glucose, and fructose, were tested.
stipitis does not require the addition of vitamins to the fermentation of xylose and it is able to use different sugars as substrates, such as glucose and
cellobiose (Agbogbo & Wenger, 2007; Bellido et al., 2011).

where C was the concentration of hydrolysis product, Ss was the peak area of standard sugar sample, S was the peak area of hydrolysis product, and [C.sub.s] was the concentration of standard sugar sample, including glucose, xylose, and
cellobiose.
The pretreatment that had the greater effect for the transformation of cellulosic material to the accessible enzyme was saccharification of dilute acid, a pretreatment that generates sugars such as xylose (0.07069 g xylose/g biomass) and
cellobiose (0.02946 g cellobiose/g biomass).
It was positive for glucose, sorbitol, rhamnose, L-arabinose, melibiose, lysine, ornithine, citrate, galactoside, and
cellobiose tests and negative for sucrose, raffinose, inositol, adonitol, urea, hydrogen sulfide, indole, arginine, tryptophan deaminase, aesculin, acetoin, malonate, tartrate, acetamide, cetrimide, and Voges-Proskauer tests.
