Abstract

Methylammonium uptake and metabolism was studied in sp. ANTH (a free-living cultured isolate from ). Unlike other cyanobacteria, sp. ANTH assimilated methylammonium as a fixed nitrogen source. While N-grown sp. ANTH cells showed ammonium transport characteristics similar to those in other cyanobacteria, a specific energy-dependent methylammonium transport was noticed in methylammonium-grown cells. Unlike methylammonium/ammonium transport in N-grown cells, methylammonium transport in methylammonium-grown cells was neither affected by ammonium nor by -methionine--sulphoximine.
