General description

Violacein from Janthinobacterium lividum is used as a colorant for natural and synthetic fabrics. It functions as a respiratory pigment and regulates tryptophan production. Violacein exhibits anti-protozoal activity.

Application

Violacein from Janthinobacterium lividum has been used:
  • for cell culture assays
  • as a standard to determine the crude violacein concentration in ethanol extracts of D. violaceinigra str. NI28 cultures
  • as a standard to identify violacein in the leaf samples of Nicotiana

Biochem/physiol Actions

Violacein, a violet pigment, is an indole derivative produced by various bacterial strains such as Chromobacterium violaceum, Janthinobacterium lividum, Chromobacterium lividum, and Pseudoalteromonas luteoviolacea. Violacein is a member of a novel class of cytotoxic drugs, which mediate apoptosis. Violacein exhibits antitumoral, antibacterial, antiulcerogenic, antileishmanial, and antiviral activities. Violacein and its β-cyclodextrin complexes trigger apoptosis and differentiation in HL60 leukemic cells. Violacein cytotoxicity is preceded by activation of caspase 8, transcription of NF-κB target genes, and p38-MAPK activation resembling TNF-α signal transduction.

A methanol-soluble extract of the bark of Myristica cinnamomea was found to exhibit anti-quorum sensing activity, and subsequent bioassay-guided isolation led to the identification of the active compound malabaricone C (1). Compound 1 inhibited violacein production by Chromobacterium violaceum CV026

The present work highlighted the production of violacein by the locally isolated Chromobacterium violaceum (GenBank accession no. HM132057) in various agricultural waste materials (sugarcane bagasse, solid pineapple waste, molasses, brown sugar), as an alternative to the conventional rich medium. The

Emergence of antibiotic resistance among bacterial pathogens often leads to the failure of existing antibiotics to treat bacterial infections; thus, there is a need to seek alternative treatment measures. The aim of this study was to evaluate the anti-quorum sensing

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
