FIG 4.

Cello- and mannodextrins compete at the level of sugar uptake. (A) Mycelial weight (dry weight) of the indicated strains after growth for 3 days in 1% (wt/vol) glucomannan (indicated as a percentage of the weight of the WT). (B) Residual mannobiose in the supernatant of the indicated strains at the indicated times after transfer to the uptake solution (100 μM mannobiose). (C) Residual sugars in the culture supernatants of S. cerevisiae heterologously expressing CDT-1 or CDT-2 transporters, 30 min after transfer to the 100 μM uptake solutions (cellobiose [CB] or mannobiose [MB], or both disaccharides simultaneously). Different lower- and uppercase letters indicate differences within data groups that are significantly different (Tukey test, P values < 0.05 were considered significant).
