1. The Vibrionaceae 1.1. A GENERAL DESCRIPTION The family Vibrionaceae (Domain Bacteria, Phylum Proteobacteria, Class Gammaproteobacteria) is comprised of mostly motile gram-negative chemoorganotrophs, possessing at least one polar flagellum (Farmer III and Janda, 2005; Thompson and Swings, 2006). Vibrios are facultative anaerobes, having both respiratory and fermentative metabolisms, and the m...

Halophiles are in all three domains of life: Archaea, Bacteria and Eucarya. Halophilic microorganisms in addition to form major part of life biodiversity can have many biotechnological applications. The objective of this research is isolation and identification of halophilic bacteria from Urmia Lake in Iran and the study of its bacterial biodiversity. After sampling of brines from Urmia Lake fr...

1. The Vibrionaceae 1.1. A GENERAL DESCRIPTION Vibrio takes its name from the Latin word Vibrare, meaning 'to wave'. Otto Müller first used the word Vibrio as a descriptor in the 18 th century to describe bacteria with an elongated shape observed in culture (Rossello-Mora and Amann 2001). The family Vibrionaceae, first described by Véron (1965), resides within the g-proteobacteria, one of the f...

Two novel marine luminous bacteria, LC2-047T and LC1-908, were isolated from seawater in Sagami Bay in Japan and an equatorial area, respectively. The cells are Gram-negative, rod shaped and motile with one polar flagellum. These bacteria are oxidase-positive and catalase-positive, and are able to grow in 0.5‒6% NaCl (optimum 3‒5%) and at temperatures of 10‒37°C (optimum 25‒30°C). Phylogenetic ...

Background: Prior research on the microorganisms associated with the brine shrimp, Artemia franciscana, has mainly been limited to culture-based identification techniques or feeding studies for aquaculture. Our objective was to identify bacteria and archaea associated with Artemia adults and encysted embryos to understand the role of microbes in the Artemia life cycle and, therefore, their impo...
