In this work, a novel β-carotene producing strain, Serratia marcescens RB3, was isolated and identified by physiological and biochemical tests, as well as 16S rDNA sequence analysis.
The production of β-carotene by S.
marcescens RB3 was identified through HPLC analysis.
The cultivation conditions for β-carotene production by S. marcescens RB3 were optimized as 2.0% lactose, 2.0% peptone, 0.3% beef extract, 1.0% NaCl 2 supplemented with 0.05% Fe , pH 6.0 and 30ºC.
Under the optimal co...
