摘要

Abstract

Eutrophication

which is the enrichment of a water mass with inorganic and organic nutrients that support plant growth

is a key factor in stimulating phytoplankton growth. In this study

we determined the effects of various nitrogen sources

different nitrogen concentrations in the culture medium

and two culture methods on the growth of the green alga

Enteromorpha prolifera. The relationship between the specific growth rate of E. prolifera and NO 3 − -N concentration was consistent with that estimated using the Monod equation (R 2 = 0.9713

P < 0.01). In the NO 3 − -N medium

the maximum specific growth rate was calculated to be 0.1634/d and the semi-saturation constant was calculated to be 16.86 μmol/L. Our results show that E. prolifera can effectively utilize NH 4 + -N

NO 3 − -N

and NO 2 − -N and urea-N in the range of 5 to 50 μmol/L. NH 4 + -N was preferentially assimilated by E. prolifera

and urea-N was favorable for long-term growth.
