Isolation and Identification of Chromobacterium Sp. From Different Ecosystems

Abstract

Objectives: The study was aimed at isolating and identifying violacein-producing bacteria from the different ecosystems. Methods:The violet color pigment (violacein) producing bacteria was isolated and identified morphologically and genomically.Results: A total of ten bacterial Chromobacterium sp. were isolated from different sources such as soil and water. The violacein productivity was screened by the total isolates and the selected two strains were identified as Chromobacterium violaceum CV4 and Chromobacterium vaccinii CV5 by morphologically and genomically. Conclusion:In the present study, the two isolate was morphologically and genomically identified as Chromobacterium violaceum CV4 and Chromobacterium vaccinii CV5, last one was found to be the novel strain from natural sources which possess a high violacein producing capability.

Chromobacterium violaceum Infection in a Domestic Shorthaired Cat with Dog Bite Wounds

“…A study showed that the isolation and identification of Chromobacterium spp. can take up to 48 hr (Vishnu & Palaniswamy, 2016) and in general, the AST results can be retrieved by day four or five from a bacteriology laboratory. When bacterial culture and AST are performed, the recovery chance is high.…”

Extraction and Characterization of Antibacterial Pigment From Roseomonas Gilardii Yp1 Strain in Yercaud Soil

“…The isolated colonies were of the following colors: Red, brown, pink, black, violet, blue, green, cream, golden, dark orange, and light yellow. Among those, the yellow pigment-producing bacterium colonies were most dominant [11,12]. The previous reported that the soil and water samples collected from different parts of Pune were used for the isolation of pigmentproducing bacteria.…”
