Abstract: The effects of tomato ketchup, peanut oil and some metal ion on the carotenoid production were studied in this paper.The result showed that tomato ketchupand peanut oil was two kinds of important additive to carotenoid production. When thetomato ketchup of 4.5g/L, peanut oil of 1.0ml/100ml were added to the media ,the carotenoid production could increase 24.75%and13.1% respectively. Through uniform design method the best combination of metal ion was selected, which were as follows:K2SO4 1%, MgSO4•7H2O 0.0476%, CuSO4•5H2O 0.00449% ,the carotenoid production could increase17.03%.

Key words: carotenoid, additive, metal ion, fermentation
