· Unfortunately, direct talc addition proved to be infeasible for natamycin fermentation in a 5 L fermentor, which was attributed to physical damage from rapid agitation and excessive talc crashing. Therefore, the morphology engineering strategy was preferred in the seed preculture process rather than formal fermentation for natamycin production.

:Talc MineralMagnesium SilicateWhat is Talc. The term talc refers both to the pure mineral and a wide variety of soft, talc-containing rocks that are mined and utilized for a variety of applications. Talc forms mica-like flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction.
