Abstract

The invention provides methods for improving efficiency of fermentation by arginine supplementation, and genetically modified bacterium for use therefor. More particularly the invention provides methods for (i) increasing the production ATP intensive products with arginine supplementation, (ii) increasing utilization of arginine by a C1-fixing bacterium; and (iii) providing C1-fixing bacterium with optimized arginine de-aminase pathways.
