Biological dinitrogen fixation by selected soil cyanobacteria as affected by strain origin, morphotype, and light conditions

Original language description

The potential for N2 fixation by heterocystous cyanobacteria isolated from soils of different geographical areas was determined as nitrogenase activity (NA) using the acetylene reduction assay. Morphology of cyanobacteria had the largest influence on NAdetermined under light conditions. NA was generally higher in species lacking thick slime sheaths. The highest value (1446 nmol/h C2H4 per g fresh biomass) was found in the strain of branched cyanobacterium Hassalia (A Has 1) from the polar region. A quadratic relationship between NA and biomass was detected in the Tolypothrix group under light conditions. The decline of NA in dark relative to light conditions ranged from 37 to 100 % and differed among strains from distinct geographical areas. Unlike the NA of temperate and tropical strains, whose decline in dark relative to light was 24 and 17 %, respectively, the NA of polar strains declined to 1 % in the dark.
