Figure 3From: Production of L-carnitine by secondary metabolism of bacteriaEffect of different transport engineering strategies on L-carnitine production. Permeabilization of Proteus sp. (A) and E. coli O44K74 (B) cells using detergents and organics. L-carnitine production by E. coli O44K74 under salt stress conditions (C). Bar represents productivity and lines the yield.
