It was known that pyridine and Triton-x100 had a bad effect on the cell growth and lycopene production were studied. The results indicated that pyridine and triton-x100 inhibited cell growth and lycopene synthesis;β-ionone increased cell growth and lycopene synthesis when the concentration was 0.05 ml/L, but when the concentration became higher, there would be a decrease on the lycopene output; span-20 increased cell growth and lycopene synthesis effectively when the concentration reached 2.0ml/L, and the lycopene yield became 2.4×10~(-2) mg/L which was 3-fold than control.
