Me. Bushell et al., EFFECT OF SMALL-SCALE CULTURE VESSEL TYPE ON HYPHAL FRAGMENT SIZE ANDERYTHROMYCIN PRODUCTION IN SACCHAROPOLYSPORA-ERYTHRAEA, Biotechnology letters, 19(9), 1997, pp. 849-852
Erythromycin production dynamics in stirred, baffled shaken and non-ba
ffled shaken flasks was strongly correlated with the different distrib
utions of hyphal particle diameters observed. Production only took pla
ce when hyphal fragments with diameters greater than 88 mu m were obse
rved. Results are consistent with significant hyphal breakage rates, e
ven in non-baffled shaken flasks.
