THE tissue test method1, 2 has proved useful in the diagnosis of mineral element deficiencies in a variety of crop plants. Using this technique, however, it has not been possible hitherto to detect deficiency-levels of manganese in plant extracts, du

(1) A dissimilatory nitrate reductase (nitrate:(acceptor) oxidoreductase, EC 1.7.99.4) which is associated with cell membranes has been purified from a photosynthetic bacterium, Rhodobacter sphaeroides f.sp. denitrificans. (2) The heat-released enzym

Summary: We have compared the effect of diphenylamine (DPA) on the pigment composition of Rhodopseudomonas sphaeroides f. sp. denitrificans grown in photoheterotrophic culture with the previously reported effect of nitrate. It was demonstrated that t

Summary: Glutamine synthetase (EC 6.3.1.2) was purified about 430-fold from the nitrifying bacterium Nitrobacter agilis by affinity chromatography on Blue Sepharose CL-6B and gel filtration on Sepharose 4B. The enzyme (apparent mol. wt 700000), which

A membrane-bound, sulphide-linked nitrite reductase from Thiobacillus denitrificans was solubilized and after further purification its properties were examined. The purified enzyme, mol. wt 120 000, contained cytochromes c and d in the ratio of 1:1.

Bacteroids of Bradyrhizobium japonicum strain CB1809, unlike CC705, do not have a high level of constitutive nitrate reductase (NR; EC 1.7.99.4) in the soybean (Glycine max. Merr.) nodule. Ex planta both strains have a high activity of NR when cultur

Glutamine synthetase (EC 6.3.1.2) has been purified from Rhizobium japonicum strains CC705 and CC723 respectively. The purified enzyme, which had a molecular weight of 720,000 (both strains) contained 12 subunits each of 60,000. The enzyme assayed by

SUMMARY: Nitrobacter agilis, a chemolithotrophic bacterium, utilizes ammonia as well as nitrite as a nitrogen source for growth. The growth yields were increased about twofold by growing the bacterium in a nitrite medium supplemented with 2 mm-ammoni
