First draft genome sequence of a strain from the genus Fusibacter isolated from Salar de Ascotán in Northern Chile

Abstract

Fusibacter sp. 3D3 (ATCC BAA-2418) is an arsenate-reducing halotolerant strain within the Firmicutes phylum, isolated from the Salar de Ascotán, a hypersaline salt flat in Northern Chile. This high-Andean closed basin is an athalassohaline environment located at the bottom of a tectonic basin surrounded by mountain range, including some active volcanoes. This landscape can be an advantageous system to explore the effect of salinity on microorganisms that mediate biogeochemical reactions. Since 2000, microbial reduction of arsenic has been evidenced in the system, and the phylogenetic analysis of the original community plus the culture enrichments has revealed the predominance of Firmicutes phylum. Here, we describe the first whole draft genome sequence of an arsenic-reducing strain belonging to the Fusibacter genus showing the highest 16S rRNA gene sequence similarity (98%) with Fusibacter sp. strain Vns02. The draft genome consists of 57 contigs with 5,111,250 bp and an average G + C content of 37.6%. Out of 4780 total genes predicted, 4700 genes code for proteins and 80 genes for RNAs. Insights from the genome sequence and some microbiological features of the strain 3D3 are available under Bioproject accession PRJDB4973 and Biosample SAMD00055724. The release of the genome sequence of this strain could contribute to the understanding of the arsenic biogeochemistry in extreme environments.Electronic supplementary materialThe online version of this article (doi:10.1186/s40793-017-0252-4) contains supplementary material, which is available to authorized users.

Meta-Analysis of Microbial Communities in Hot Springs: Recurrent Taxa and Complex Shaping Factors beyond pH and Temperature

“…Sphingomonas genus comprises Gram-negative, chemoheterotrophic, strictly aerobic bacteria that are free-living in natural and man-made environments, including polluted and unpolluted sites [ 60 ]. Two additional genera were also identified in this sample, Fusibacter and Herbinix ; the first one has been isolated from oiled environments and has arsenate-reducing potential [ 61 , 62 ], while the second one comprises thermophilic cellulose-degrading bacteria [ 63 , 64 ]. Conclusively, this first approach to the indigenous microbial community of Domuyo revealed a rich and interesting environment which could host new and biotechnologically useful organisms.…”

Pressure and temperature effects on deep‐sea hydrocarbon‐degrading microbial communities in subarctic sediments

“…Fusibacter (Phylum Firmicutes) was found in higher relative abundance in 20°C, 0.1 MPa, and oil‐contaminated incubations. Fusibacter has been previously described as a sulfur reducer at mesophilic Ts (Serrano et al, ). Type strain Fusibacter paucivorans has been isolated from an oil well (Ravot et al, ) and Fusibacter bizertensis from a kerosene tank (Smii et al, ).…”

Bacterial Community Response in Deep Faroe-Shetland Channel Sediments Following Hydrocarbon Entrainment With and Without Dispersant Addition

“…Yang et al (2016) showed this may be the result of heterogeneous redox conditions forming within the sediment due to smothering by oil residues and the development of anoxic micro-niches. Fusibacter are generally halotolerant fermentative anaerobes capable of reducing a range of sulfur species and often isolated at mesophilic temperatures (Serrano et al, 2017). Several strains have been isolated from hydrocarbon related environments including the type strain Fusibacter paucivorans isolated from an oil-producing well (Ravot et al, 1999) and Fusibacter bizertensis isolated from a corroded kerosene storage tank (Smii et al, 2015).…”
