摘要
为进一步研究、探讨和开发海洋硅藻,研究了醋酸对海洋硅藻海链藻(Thalassiosirasp .)生长的影响。结果表明,pH值为8.0～9.0时,以醋酸调节pH值时海链藻的生长率高于用盐酸调节pH值时的生长率。1次性添加10～10 0mg/L醋酸都可促进海链藻生长;每日1次添加5～60mg/L的醋酸时,可明显提高海链藻的生长率。
In the present paper, the stimulating effect of acetic acid on Thalassiosira sp. was investigated. In the range of pH value from 8.0 to 9.0, Thalassiosira sp. grew more rapidly when pH was regulated by acetic acid than that by hydrochloric acid; and while acetic acid (concentration being from 10mg/L to 100mg/L) was added was added to the culture medium, it could accelerate the growth of Thalassiosira sp., and when acetic acid (concentration from 5mg/L to 60mg/L) was added to the culture medium daily, higher growth rates than that in normal conditions were obtained.
