Viability of bacteria when cocultured with yeast in lignocellulosic medium. Viability was determined during batch cultures of the yeast Saccharomyces cerevisiae (filled stars) alone and in coculture with Lactobacillus buchneri (open circles), Lactobacillus fermentum (open squares), Lactobacillus plantarum (diamonds) Acetobacter syzygii (upwards triangles), and Acetobacter tropicalis (downwards triangles) on a lignocellulosic medium from chips of spruce hydrolyzed with dilute acid. The composition of the medium is described in [14]. In each case, results from two independent cultures performed in falcon tubes are shown.
