CULTURE INFORMATION
Culture medium:ESP Ag
Axenic:axenic
Strain relatives:only valid for original strain SAG 698-1a: CCAP 698/1A; UTEX 42; CAUP K 402a; Prague 208; M. Mix 241
Agitation resistance:not detected
Special properties:strain probably mixed or mislabelled between 1985 and 2006; maybe identical to SAG 698-2 now; sequence data show that this strain belong rather to C. cylindricum than to C. circumcarinatum. Feng et al. 2021; NO known Nagoya Protocol restrictions for this strain; dioecious; + strain
