| 摘 要： | 海洋生物发光研究对渔业、环境监测等有着举足轻重的意义.本文从湛江东海岛海域沉积物样品中分离出一株海洋发光弧菌(Vibrio sp.),本研究中编号为D2,对这株菌的生长和发光条件进行了初步研究.实验结果表明, 海洋发光弧菌D2 在pH 7.0、温度35 °C、NaCl 浓度为2.0 %时,生长状态最好;在pH5 - 6、温度20 °C、NaCl 浓度为3.0 %、细菌密度OD600达0.08时,发光强度最高. |

| Abstract: | Study of marine noctilucence in marine is important to fishery, environmental monitoring and military affairs. A luminous bacterial strain D2 was isolated from the marine sediment samples collected near Donghai Island in Zhanjiang, China. The primary cultural and luminescent conditions of luminous bacterium D2 which was identified as Vibrio sp. were determined in liquid culture. The results showed that pH 7.0, 35 °C, with 2.0 % NaCl, were the best growth conditions, and pH5 - 6, 20 °C, OD600 0.08, with 3.0 % NaCl, were the optimal luminescent conditions. |
