摘要: 在正交试验条件下,分析了盐度、温度、光照强度对海洋卡盾藻生长和产毒的影响.结果表明:在盐度22、33、45和温度20 ℃、25 ℃、30 ℃以及光照强度2000、3000、4500 lx条件下,三因素对海洋卡盾藻生长的影响均不显著,盐度是影响海洋卡盾藻产毒的主要因子;盐度45、温度30 ℃、光照2000 lx下海洋卡盾藻的比生长速率最大,盐度22、温度20 ℃、光照4500 lx下海洋卡盾藻的产毒能力最强;低盐条件不利于海洋卡盾藻的生长,但有利于溶血毒素的合成;当海洋卡盾藻生长受到限制时,其溶血毒素合成增多.

Abstract: A laboratory experiment with orthogonal design was conducted to study the effects of factors salinity, temperature, and light intensity on the growth and toxin production of Chattonella marina. Three levels of salinity (22, 33, and 45), temperature (20 ℃, 25 ℃, and 30 ℃) and light intensity (2000, 3000, and 4500 lx) were installed. In all treatments, the three factors had no significant effects on the growth of C. marina, but salinity significantly affected the toxin production of C. marina. Under salinity 45, temperature 30 ℃ and light intensity 2000 lx, C. marina had the maximal growth rate; under salinity 22, temperature 20 ℃ and light intensity 4500 lx, the toxin production of C. marina was the maximal. Low salinity was not favorable to the C. marina growth but favorable to its haemolytic toxin production. When the growth of C. marina was limited, its haemolytic toxin production increased.
