16. Hydrogenases in the Cyanobacterium Nostoc sp. Strain PCC 73102
Abstract : Many cyanobacteria are capable of fixing atmospheric N2, a reaction that is also producing H2. This hydrogen is often metabolized by an enzyme called hydrogenase. The aim of the present work was to identify and characterize hydrogen metabolism/hydrogenases in the free-living N2-fixing cyanobacterium Nostoc sp.strain PCC 73102. READ MORE
