Sarcina flava

Entrapment of porcine kidney tissue slices or Sarcina flava cells into nylon nets or hollow fiber dialysis units and placement in line with an ammonia electrode for flow-though analysis Glutamine [64]... 

Another example deals with amino acid analysis using immobilized specific microorganisms in combination with selective electrodes (35). Thus, glutamine could be analyzed by an electrode consisting of a potentiometric ammonia gas sensor and a layer of the bacterium Sarcina flava (American type culture collection 147) trapped in the volume between a NHo-permeable membrane on the surface of the electrode and a dialysis membrane in contact with the surrounding solution (Fig. 10). Using this electrode, steady state potentials were reached within 5 minutes. 

Specific ion and specific gas electrodes, as well as other electrode types, can be employed. Examples of the types of bacterial electrodes include the use of Streptococcus foecium immobilized on an ammonia electrode to sense arginine,the use of Sarcina flava and an ammonium electrode to sense L-glutamine, and the use of Lactobacillus fermenti and a platinum, silver peroxide electrode to sense vitamin...
