PhaB-independent poly(3-hydroxybutyrate) production in the thermophilic hydrogen-oxidizing bacterium Hydrogenophilus thermoluteolus

Kotaro Yoda, Masafumi Kameya, Hiroyuki Arai

This study shows that Hydrogenophilus thermoluteolus can produce PHB without PhaB enzymes, suggesting alternative metabolic pathways for PHB synthesis.

Impact of acetate on CO2 fixation pathways in thermophilic and hydrogenotrophic bacteria

Yoko Chiba, Tomomi Sumida, Masafumi Kameya…·Takuro Nunoura

This study examines how acetate affects CO2 fixation pathways in thermophilic bacteria, showing acetate suppresses the WL pathway and promotes the rTCA cycle in some species.
