Abstract
A novel bioselective membrane electrode for L-glutamine has been constructed by coupling living bacteria of the strain Sarcina flava to a potentiometric ammonia gas sensor. Tests in aqueous standards and human serum show that the electrode combines excellent sensitivity and selectivity with rapid response and a useful lifetime of at least 2 weeks.
