From: Combinatorial approach for improved cyanidin 3-O-glucoside production in Escherichia coli
Isolation, extraction, and analysis of both extracellular and intracellular cyanidin-3-O-glucoside (C3G) in E. coli culture in modified M9 minimal medium after 36Â h of incubation. a UHPLC-PDA profile of C3G. b Extraction of intracellular C3G by sonication, followed by centrifugation. The vials 1, 2, 3, 4, 5, and 6 show supernatant after each extraction. c The remaining cell pellets of different C3G producing strains after final extraction
