Abstract excerpt
Mutants of Gloeotrichia ghosei fil1 het++ and pol- het- failed to grow on molecular nitrogen and required combined nitrogen sources. NO3- and NH4+ supported maximum growth of parent and mutant strains under aerobic conditions but not under reducing anaerobic or heterotrophic conditions. Glutamine and tryptophan were superior for the parent strain compared to inorganic nitrogen sources. By mutants only glutamine...
