The polyhydroxyalkanoic acid synthase gene from Chromobacterium violaceum (phaC(Cv)) was cloned and characterized. A 6.3-kb BamHI fragment was found to contain both phaC(Cv) and the polyhydroxyalkanoic acid (PHA)-specific 3-ketothiolase (phaA(Cv)). Escherichia coli strains harboring this fragment produced significant levels of PHA synthase and 3-ketothiolase, as judged by their activities. Whil...

Conventional leaching (extraction) methods for gold recovery from electronic waste involve the use of strong acids and pose considerable threat to the environment. The alternative use of bioleaching microbes for gold recovery is non-pollutive and relies on the secretion of a lixiviant or (bio)chemical such as cyanide for extraction of gold from electronic waste. However, widespread industrial u...

Strain CC-SEYA-1T, a motile, Gram-negative, non-violet-pigmented bacterium, was isolated on nutrient agar from spring-water samples collected from Yang-Ming Mountain, Taipei County, Taiwan. 16S rRNA gene sequence studies showed that the strain clustered with Chromobacterium violaceum (96.8 % similarity) and Chromobacterium subtsugae (96.5 % similarity), followed by Aquitalea magnusonii (95.8 % ...

Aconitum violaceum Jacq. ex Stapf is endemic to the Northern Himalayan regions of India, Pakistan and Nepal. To adapt endure rigorous stressful situations, phenotypic features a specific plant species vary across different climatic conditions elevations. The aim this study was reveal impact altitude environmental on morphological attributes threatened A. violaceum. Plants at high elevations (Ma...

We announce the draft genome sequence for Chromobacterium violaceum strain CV017, used as a model and tool to understand acyl-homoserine lactone-dependent quorum sensing. The assembly consists of 4,774,638-bp contained in 211 scaffolds.

Dermatophyte fungi are the etiologic agents of skin infections commonly referred to as ringworm. These infections are not dangerous but as a chronic cutaneous infections they may be difficult to treat and can also cause physical discomfort for patients. They are considered important as a public health problem as well. No information is available regarding the efficacy of antifungal agents again...

Chromobacterium violaceum is a rare human pathogen with a high rate of mortality. Since the first case from Malaysia in 1927, about 150 cases have been reported till 2004 in the world literature [1]. We report a case of septicaemia with bronchopneumonia in a young healthy male.

Many members of the genus Chromobacterium produce violacein, a characteristic purple pigment which is induced by small diffusible N-acyl homoserine lactones (AHL) quorum-sensing molecules. In this study, the production of AHL of the non-pigmented C. aquaticum CC-SEYA-1(T) and the pigmented C. subtsugae PRAA4-1(T) were determined by using a CV026 biosensor assay. The profile of AHL was identifie...
