Degradation of 1,4-dichlorobenzene by Xanthobacter flavus 14p1.

abstract：:The codon-optimized genes crtB and crtI of Pantoea ananatis were expressed in Yarrowia lipolytica under the control of the TEF1 promoter of Y. lipolytica. Additionally, the rate-limiting genes for isoprenoid biosynthesis in Y. lipolytica, GGS1 and HMG1, were overexpressed to increase the production of lycopene. All of...
