ABSTRACT
Among inorganic salts tested, K 2HPO 4 was more essential to the sclerotia for mation and carotenogenesis of strain PT95 than KCl, MgSO 4 or FeSO 4 It wa s also shown that the combination of K 2HPO 4, KCl and MgSO 4 could produce t he best positive cooperation and give the highest sclerotia biomass (782mg/plate ) and pigment yield (328 ?g/plate) Five carbon sources, i e glucose sucros e, lactose, maltose and soluble starch, all could be utilized by the strain PT95 , and maltose was the best Among 8 nitrogen sources, yeast extract favooured t he sclerotia formation, and peptone fovoured the pigment accumulation; amine sal ts and urea were unfavourable to form sclerotia The medium containing 0 24 ~ 0 48 g/L sodium nitrate nitrogen was effective to both the sclerotia formation and the carotenoid production of strain PT95 when available maltose carbon con centrations were at 5 26~21 05 g/L The optimal C/N ratio was found to be 25 ∶1
