Metabolites are produced during stirred tank reactor fermentation of N. cameroonii G341 with straw as the sole carbon source depending on the stirrer velocities of 250 rpm and 600 rpm. Displayed are the final amount after 6 days (250 rpm) and 10 days (600 rpm) of cultivation. Ø is the mean value of the duplicate and SD the corresponding standard deviation
