Enniatin B titres during wave-mixed fed-batch cultivations obtained from the A. niger strains DS3.1 and ÖV4.10. Volumetric enniatin B yields (g L−1 culture broth) from duplicate cultures are given, which were measured as technical replicates. Enniatin B was determined after 100 h of each cultivation approximately every 10 h. Biological and technical replicates are summarized in each box–whisker-plot
