Stabilization of the Penicillium chrysogenum strain with pelletized morphological structure by selection, multiplication, and control of the variability of pure cultures

This study showed that Penicillium chrysogenum exhibits during submerged cultivation two distinct features: a filamentous structure characterized by long, branched, loose hyphae, and a pelletized morphological structure characterized by short, thickened hyphae clustered in a glomerule-like formation...

Description
Summary:This study showed that Penicillium chrysogenum exhibits during submerged cultivation two distinct features: a filamentous structure characterized by long, branched, loose hyphae, and a pelletized morphological structure characterized by short, thickened hyphae clustered in a glomerule-like formation called pellet. With a view to maintaining the potential to biosynthesize the pelletized strain penicillin to a maximum, the operations involving the selection, multiplication and variability control of pure culture should be conducted periodically to prevent phenotypic and genotypic deviations to parental forms.
