摘　　要：Tetraselmis sp.-1 is a new microalgae strain constructed by cell fusion technique. In this paper, the growth characteristics of Tetraselmis sp.-1 under different culture conditions are investigated. The growth kinetic models are obtained, the assimilation of C and NH4+ is investigated and the assimilation efficiency of Tetraselmis sp.-1 under different culture conditions is calculated. The results show that different culture conditions do not have obvious influence on carbon absorbance, but have significant influence on nitrogen absorbance, C∶N is maximum under heterotrophic condition, while minimum under phototrophic condition. The assimilation efficiency (η) of Tetraselmis sp.-1 has the highest value in heterotrophic condition and largely higher than those in phototrophic and mixotrophic conditions.
