Figure 6

Fold change in viable yeast (closed bars) and viable bacteria (open bars) after 24 h incubation in lignocellulosic medium with and without additions of ethanol and/or NaCl. The fold change of viable yeast and bacteria was calculated after 24 h incubation in falcon tubes of a mixture of the yeast Saccharomyces cerevisiae and the bacteria Lactobacillus buchneri, Lactobacillus fermentum, Acetobacter syzygii and Acetobacter tropicalis inoculated into a dilute acid spruce hydrolysate medium with and without various additions of ethanol and/or NaCl. A missing bar means that the change is lower than onefold.
