1. Effects of Enhanced Mixing and Minimal Co2 Supplementation on Biomass and Nitrogen Concentration in a Nitrogen-fixing Anabaena Sp. Cyanobacteria Biofertilizer Production Culture

Nitrogen-fixing cyanobacteria are attractive as a nitrogen fertilizer because they are ubiquitous in nature and have minimal nutrient requirements. Our lab is scaling up production of a local strain of the nitrogen-fixing cyanobacterium Anabaena sp. in on-farm open raceways to determine its exonomic ppotential as a nitrogen fertilizer for horticultural crops. Our goal is to increase productivity in an organically certifiable growth medium above the current two week batch production levels... J. G. Davis, J. Wenz, H. Storteboom
