Carbon-Convergent Co-utilization of Ethanol and CO2 Enables Efficient 3-Hydroxypropionic Acid Biosynthesis in Komagataella phaffii
This study establishes a carbon-convergent strategy in engineered *Komagataella phaffii* that co-utilizes ethanol and CO2 to achieve a record-breaking 3-hydroxypropionic acid titer of 127.04 g/L, demonstrating the feasibility of coupling chemical CO2 reduction with microbial biosynthesis.
