[Purpose]
Hydrogen (H2) increasingly gains attention as a promising solution for a sustainable energy future. Biohydrogen production from renewable, low-cost, and abundant resources, offers an economically attractive and environmentally friendly approach. One-carbon (C1) substrates such as carbon monoxide (CO) and formate derived from industrial byproduct/waste-gases and electrochemical CO2 reduction may present economically viable solution for large-scale H2 production. We have investigated biohydrogen production using Thermococcus onnurineus NA1, a hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent area near Papua New Guinea.
[Results]
The genome of T. onnurineus NA1 encodes seven different hydrogenases, enabling the strain to grow and produce hydrogen from various substrates including CO and formate. Through a combination of genetic engineering and adaptive laboratory evolution, we significantly enhanced H2 production rate of the strain. Furthermore, we could successfully demonstrate the feasibility of biohydrogen production by utilizing industrial byproducts and waste gases in large-scale bioreactors. To address the inherent challenges of H2 storage and transport, we also explored the potential of formate as a Liquid Organic Hydrogen Carrier (LOHC) using T. onnurineus NA1. The latest achievements regarding biohydrogen production from one-carbon substrates using T. onnurineus NA1 will be discussed.
[Conclusion]
This research offers valuable insights into the development of gas fermentation and biohydrogen technology using a hyperthermophilic archaeon.
