Complete genome sequence of Halocynthiibacter arcticus PAMC 20958(T) from an Arctic marine sediment sample.

Here, we present the first complete genome sequence of the strain PAMC 20958(T) from the genus Halocynthiibacter. Halocynthiibacter arcticus PAMC 20958(T), isolated from a marine sediment of the Arctic, is a gram-negative, aerobic, and rod-shaped bacterium. The complete genome contains 4,329,554 base pairs with 53.21% GC content and a 44,566 base pair plasmid with 48.72% GC content. This genome contained genes encoding alkaline phosphatase and lipase, and genes that confer resistance to arsenic, cadmium, tellurite, and acriflavin. Copyright © 2016 Elsevier B.V.

Complete genome sequence of opine-utilizing Variovorax sp. strain PAMC28711 isolated from an Antarctic lichen.

We report the complete genome sequence of Variovorax sp. strain PAMC28711 isolated from the Antarctic lichen Himantormia sp. Whole genome sequencing revealed opine oxidase- and octopine dehydrogenase-related gene clusters that are involved in octopine utilization. These data will lead to future genetic and biochemical studies on the unusual catabolic traits of opine and octopine utilization in extremely cold environments. Copyright © 2016 Elsevier B.V.

Complete genome sequence of carotenoid-producing Microbacterium sp. strain PAMC28756 isolated from an Antarctic lichen.

Microbacterium sp. strain PAMC28756, of the family Microbacteriaceae, was isolated from Stereocaulon sp., an Antarctic lichen. Complete genome sequencing of Microbacterium sp. PAMC28756 revealed, for the first time in the genus Microbacterium, a series of key genes involved in C50 carotenoid biosynthesis. An analysis of the Microbacterium sp. PAMC28756 genome will lead to a better understanding of the carotenoid biosynthesis pathway. Furthermore, the sequence data will provide novel insight into UV radiation resistance in extremely cold environments. Copyright © 2016 Elsevier B.V. All rights reserved.

Complete genome sequence of Colwellia hornerae PAMC 20917, a cold-active enzyme-producing bacterium isolated from the Arctic Ocean sediment

Psychrophilic bacteria are considered a source of cold-active enzymes that can be used in industrial applications. The Arctic bacterium Colwellia hornerae PAMC 20917 strain has been isolated from the offshore sediment near Ny-Ålesund, Svalbard. The optimal growth temperature of the strain was 10?°C on marine agar. The cell lysate showed alkaline phosphatase activities. Analysis of the enzymatic properties showed that the alkaline phosphatase was cold-active and thermolabile. To explore useful cold-active industrial enzymes further, the entire genome of the PAMC 20917 strain was sequenced. The genome of the strain contained 4,684,314 nucleotides, with 37.87% G+C content. Genome mining analysis revealed that, in the complete genome sequence, three proteins were annotated as alkaline phosphatases. The genome of PAMC 20917 encodes cold shock proteins and an ice-binding protein that inhibits the growth of ice, allowing the bacterium to adapt to cold environments. This genome information may be useful for understanding mechanisms of adaptation to cold stress.
