🧬 Scientists engineered genetic circuits to improve the productivity of industrial E. coli at low pH Low pH fermentation in industrial processes provides significant benefits like reducing the need for neutralizers and wastewater output, especially in producing amino acids and organic acids. The researchers created a quorum-sensing gene circuit that activates acid-resistance genes during exponential growth and deactivates them in stationary phases. This reduces unnecessary energy consumption, enabling E. coli strains to sustain high productivity in acidic conditions. The engineered E. coli strain produced 102 g/L of lysine at pH 5.5, with 4% less glucose consumption and 10% lower ammonia usage. This indicates improved production efficiency and sustainability through better resource use and reduced waste. ✉️ Hungry for more updates on biotech-enabled agrifood businesses and breakthroughs?
