Abstract:
A study has been made to determine which nutrient factors control antibiotic production by the cyanobacterium, Nostoc muscorum. A two-phase approach was employed using a factorial method to explore the response surface and a steepest ascent method to climb the response surface to the region of the optimum. It was found that nitrate and iron were the factors significantly affecting antibiotic production; 26.4 mM nitrate and 6 microM iron were the optimal concentrations for maximizing antibiotic production by N. muscorum.
