A biohydrogen platform from swollen chitin was developed using the hyperthermophilic archaeon Thermococcus kodakarensis. Combining targeted genetic engineering with adaptive engineering, a strain (KC04ΔtM1) was obtained that efficiently converts swollen chitin to hydrogen (H₂) at 85 °C. This work offers an important step toward the future biohydrogen production using waste biomass.

摘要

A biohydrogen platform from swollen chitin was developed using the hyperthermophilic archaeon Thermococcus kodakarensis. Combining targeted genetic engineering with adaptive engineering, a strain (KC04ΔtM1) was obtained that efficiently converts swollen chitin to hydrogen (H₂) at 85 °C. This work offers an important step toward the future biohydrogen production using waste biomass.
