The natural antimicrobial carvacrol inhibits quorum sensing in Chromobacterium
violaceum and reduces bacterial biofilm formation at sub-lethal concentrations.
cepacia1 -- AAA50466.1 Vibrio cholerae 12129(1) EEN99655 Rhodoferax ferrireducens T118 WP_011465630.1 Myxococcus xanthus -- WP_011555480.1 Chromobacterium
violaceum ATCC12472 NP_902384.1 C.
violaceum is a Gram-negative, facultative anaerobe, motile, oxidase and catalase positive bacilli which produce a purple pigment violacein which is alcohol-soluble, water and chloroform insoluble.
MORTALITY ATTRIBUTABLE TO CHROMOBACTERIUM
Bacterial strains used in the present investigation were Chromobacterium
violaceum ATCC 12472, Pseudomonas aeruginosa PAO1, Serratia marcescens ATCC 13880, and Listeria monocytogenes (laboratory strain).
The wide spread of Chromobacterium
throughout a variety of environments, such as soil, water, and plant from tropical and subtropical regions, is due to its considerable metabolic flexibility [12-16].
