Abstract
报道了在实验室培养条件下塔马亚历山大藻(Alexandrium tamarense) 与几株海洋细菌之间的生态关系。实验表明, 在培养前期, 培养液中的营养成分尚足以维持藻类和细菌的生长, 细菌的加入是胞外酶活性升高的主要原因所在; 在培养的后期, 混合培养液和藻对照培养液中胞外酶活性持续升高。A. tamarense 在单独培养下,其胞外酶活性从第12 天起才有明显的提高,第16 天增加较快,达到0. 104μmol/ (L ·h) ; 至第20 天藻体衰败时,胞外酶活性达到最高水平,为0. 385μmol/ (L ·h) 。Z7 细菌单独培养时,其胞外酶活性在单独培养的2d 后有一个高峰值0.133 μmol/(L ·h), 随着培养时间的延长, 其酶活性逐渐降低。细菌Z7 和Z10 与A.tamarense 共培养下,两者胞外酶活性变化趋势相似。国家973 项目2001CB409710 号; 国家自然科学基金项目39790110 号和30070157 号
