Use of a mutant strain of the cyanobacterium Synechococcus R2 for the determination of nitrate.

Analytical biochemistry - 1 Oct 1991

Madueño F, Guerrero M G

Abstract excerpt

A sensitive procedure for the determination of nitrate within the 1- to 50-microM range is described. The method is based on the photoreduction of nitrate to nitrite by whole cells of a nitrite reductase-less mutant strain of the unicellular cyanobacterium Synechococcus R2. Cell suspensions of this cyanobacterium retain high levels of nitrate photoreduction activity for at least 2 months when maintained in the...
