Bacterial electrode for L-arginine.
Streptococcus lactis bacterial cells are employed for the conversion of L-arginine into ammonia. An ammonia gas-electrode is used as a detector. The combination of bacterial action and the gas electrode responds linearly to L-arginine over the concentration range 8.0 x 10(-6) - 1.0 x 10(-3)M, with a slope of 59.0 mV/decade and is selective with respect to other l-amino acids.
