Growth of strain L1 during 7 days incubation with lignin or glucose as carbon source. Symbols: closed circles glucose and lignin as carbon source incubated at 50 °C; closed squares lignin as single carbon source incubated at 50 °C; closed diamond glucose and lignin as carbon source incubated at 30 °C; closed triangles lignin as single carbon source incubated at 30 °C; open circles the concentration of glucose during incubation of strain L1 in culture with glucose and lignin as carbon source
