Betafectin drug production. Researcher operates a fermentation unit used to culture yeast, in the production of Betafectin drug. This drug is being produced in the laboratories of Alpha-Beta Tech- nology, USA. Betafectin is the first genetically engineered carbohydrate drug, for use against antibiotic-resistant bacteria. The drug is based on a carbohydrate found in yeast cell walls. The engineered yeast multiplies in the fermentation unit. Betafectin is thought to mimic a bacterial attack in the body. In doing so it stimulates white blood cells of the immune system to attack invading bacteria. Betafectin may be used on patients undergoing major surgery.
