Abstract: In this paper, the nutrient factors onβ-carotene production of recombinant Escherichia coli were studied. Compoundcarbon sources, glucose 10g/L and sucrose 10g/L, and beef extract 4 g/L used as nitrogen sources were favor for cell growth andβ-carotene expression. Addition NaCl1.6g/L,Span-20 0.7g/L and KH2PO4 3g/L helped forβ-carotene expression., But hadno effect on cell growth.

Key words: nutrient factors, recombinant Escherichia coli, β-carotene
