## TL;DR

Scientists sequenced the genome of a bacteria from a hot spring in Japan that produces hydrogen gas.

## Contribution

The study reports the complete genome sequence of Fervidobacterium gondwanense Kr-7 and identifies hydrogenase genes linked to hydrogen production.

## Key findings

- The genome contains hydrogenase genes potentially involved in H2 production.
- The strain ferments various organic compounds to produce CO2 and H2.

## Abstract

Fervidobacterium gondwanense Kr-7 strain (NBRC 117357) was isolated from a hot spring in Toyama Prefecture, Japan. This strain ferments a variety of organic compounds and produces CO2 and H2 as end products. Its genome sequence contains several hydrogenase genes that appear to be related to H2 production.

## Linked entities

- **Species:** Fervidobacterium gondwanense (taxon 44754)

## Full-text entities

- **Chemicals:** H2 (-), CO2 (MESH:D002245)
