Abstract:

© 2015 Springer Science+Business Media Dordrecht In experiments investigating nutrient effects on tropical Microcystis, increasing nitrogen and phosphorus concentrations were found to have a significant positive effect on maximum cell yields of two strains of Microcystis ichthyoblabe (from Lower Peirce and Tengeh Reservoirs) and one strain of Microcystis flos-aquae isolated (Lower Peirce Reservoir) from Singapore. However, only increasing nitrogen concentration had a positive effect on growth rates of M. ichthyoblabe and M. flos-aquae from Lower Peirce Reservoir. MC-RR and MC-LR were produced by all three strains with MC-RR being the dominant variant. Phosphorus played an important role in MC production with increases in phosphorus from medium to high concentrations leading to decreases in MC-RR cell quotas for all three strains at the two highest nitrogen levels tested. The different growth and toxin production responses between M. ichthyoblabe strains could be due to location-specific differences.
