Fig. 2From: Metabolic engineering of Rhodopseudomonas palustris for the obligate reduction of n-butyrate to n-butanolFluorescence screen of potential expression vectors in R. palustris CGA009. Fluorescence from each strain is expressed as relative fluorescence per 1 unit of OD600 in an exponentially growing culture. Technical triplicates with standard deviation and relevant p values are shown. Excitation/emission was measured at 480:510 nm. The control contained no cells. Different empty vectors and constructs with GFPmut2 are designated by vector/promoter headingBack to article page
