One particular problem facing producers is the contamination of fermentation vessels with other, unwanted microbes. These invaders can outcompete the producer microbes for nutrients, reducing yield and productivity. Rather than applying mass amounts of antibiotics to vats of biofuel-producing microorganisms to keep control these cultures, researchers at Massachusetts Institute of Technology (MIT) have developed a new technique using modified strains that outcompete other possible contaminating microbes.… Login to continue
