DOI: 10.1007/s00253-024-13358-1

Abstract: Violacein is a natural indole-derived purple pigment of microbial origin that has attracted attention for its remarkable biological properties. Due to its poor solubility in aqueous media, most studies of this pigment use extracts of… read more here.

DOI: 10.1016/j.ymben.2016.12.008

Abstract: Microbial fermentation conditions are dynamic, due to transcriptional induction, nutrient consumption, or changes to incubation conditions. In this study, 13C-metabolic flux analysis was used to characterize two violacein-producing E. coli strains with vastly different productivities,… read more here.

DOI: 10.1128/spectrum.00607-22

Abstract: The antibacterial activities of prodigiosin are well-established but, as a hydrophobic molecule, the mechanisms used to introduce it to susceptible microbes has never been studied. We found here, in contrast to violacein, another hydrophobic antibiotic… read more here.
