Abstract

Results of laboratory experiment examining growth, CO2- and N2-fixation of Crocosphaera watsonii isolates in differing light intensities; conducted in the Hutchins Laboratory, USC.

Results of laboratory experiments examining growth, CO2-fixation and gross and net N2-fixation rate capacities of two isolates of Crocosphaera watsonii, WH0401 and WH0402, in response to a range of light intensities. Isolates of C. watsonii, a unicellular marine N2-fixing cyanobacterium, were obtained from the western tropical Atlantic Ocean and cultured in the laboratory.

Detailed methods and results are described in the following publication (see Figure 1):
