Table 1 Morphological differences in cultures carried out in conventional Erlenmeyer normal (NF), baffled (BF), and coiled shake flasks (CF). Data are presented as average ± standard deviation of image analysis of at least 100 clumps, mycelia or pellets for each sample, and at least 3 samples were analyzed for each flask. Values with the same superscript (a,b or c) are not significantly different by Tukey HSD Test (p = 0.01).
