Abstract
A detection system for anaerobic micro-organisms involves the addition to a nutrient medium for the micro-organisms of an indicator species which is electrochemically reducible, soluble in the nutrient medium and consumed by the micro-organisms during growth. Two electrodes are immersed in the nutrient medium and changes in an electrical property of the nutrient medium are monitored. A preferred indicator species is riboflavin.
