Chromobacterium violaceum CV026 strain紫色杆菌菌株群体感应检测菌种 BioVector NTCC质粒载体菌种细胞基因保藏中心
Chromobacterium violaceum CV026
NTCC503714
Current Name: Chromobacterium violaceum
Other Collection No: CV026
Type Strain: No
Family: Neisseriaceae
Accession Date: 14/06/2007
Taxonomy: TaxLink: S793 (Chromobacterium violaceum bergonzini 1880) - Date of change: 31/05/2007
Other: biosensor strain
Description: Double mini-Tn5 mutant derived from ATCC 31532, KanR, HgR, cvil::Tn5 xylE, plus spontaneous StrR. AHL biosensor, produces violacein pigment only in the presence of exogenous AHL.
Chromobacterium violaceum (C. violaceum), a Gram negative bacterium having a wide geographic distribution, produces the pigment violacein in response to QS regulated gene expression. Further, the whole genome studies on C. violaceum showed that violacein production is regulated by vioD, vioC, vioB and vioA genes arranged in an operon through a QS system mediated by AHL. A biosensor strain, C. violaceum CV026 (mini-Tn5 mutant of wild type strain), deficient in autoinducer synthase which requires exogenous addition of AHL to produce violacein was developed for studying various QS mechanisms, and it offers a convenient tool for the biological assay of screening QS inhibitors.
CV026通常在-80oC取出后在LB中连续培养2代后使用。如果发现产紫现象不明显,可用含20-50ug/mL Kan的LB抗性平板进行连续纯化,直到产紫现象恢复。
