Nitrogen Assimilation: Optimization of N-Labelled Azoverdin Production by Azomonas macrocytogenes ATCC 12334.

abstract：:Transpositional mutagenesis of Thiobacillus novellus by Tn501 was achieved by means of the incompatibility of IncP plasmids. Tn501 insertion caused three types of mutant phenotypes: isoleucine auxotrophy, lysine auxotrophy, and a reduced ability to oxidize reduced sulfur compounds and to fix CO(2). Oxidation rates for...
