Effect of CO2 enrichment on competition between Skeletonema costatum and Heterosigma akashiwo
摘要
Abstract
We investigated the effect of CO2 enrichment and initial inoculum density on competition between Skeletonema costatum and Heterosigma akashiwo
two common algae seen in algal blooms. The initial inoculum density (0.2×104
0.4×104
0.8×104 cells/ml) had a significant effect on population growth and competition between H. akashiwo and S. costatum. The time required for population growth to reach the exponential growth phase and stationary phase decreased significantly as the initial density increased. When the two species were cultured together
S. costatum tended to outcompete H. akashiwo
especially when present at higher initial ratios. CO2 enrichment (5 000 μl/L CO2) increased the maximum population density and carrying capacity of H. akashiwo but decreased these measures for S. costatum. Thus
CO2 enrichment favored the growth of H. akashiwo over S. costatum.
