摘要
于1989年6月—1990年6月,运用开放式半连续培养的方法在海南省三亚市鹿回头海滩建113m^2养殖池,进行海水螺旋藻大量培养试验研究。结果表明:①海水螺旋藻藻种SCS品系(1984年引进非洲乍得湖Spirulina platensis经分离选育,驯化为海水螺旋藻藻种SCS品系)适宜在热带地区进行大量培养;②用海水培养螺旋藻不需调pH值;③循环使用培养液可以节约肥料和药品,是降低成本的途径之一;④海南省海岸线长,南部气温高,日照充足,在那里生产海水螺旋藻产量高[12.01g/(m^2·d)]、质量好(粗蛋白含量67.28％)。以上几点说明海南省南部滩涂可以大规模生产海水螺旋藻。
Results of experiments carried out in the Luhuitou beach area in Hainan Province from June 6, 1989 to June 15, 1990 on the use of the semi-continuous method in the mass cultivation of Spirulina platensis strain SCS in an open 113 m2 cement pond show that: 1) the average monthly temperature and total solar irradiance density conditions from March to November in Sanya, Hainan Province are optimal for the growth of Spirulina platensis strain SCS and resulted in an average dry-product yield of 12. 01 g/(m2·d) (dw).2) Buffering of culture medium was not necessary when sea water was used in culturing Spirulina. In the entire process of open, continuous culture, the culture medium was recycled and the pH was always maintained around 10.0, at most, not higher than 10 5, so pH was not a controlling factor. 3) Compared with the use of Zarrouk nutrient culture medium prepared from fresh water, the use of sea water, simplified culture medium and the recycling of culture media gave more economical results in terms of reduced cost of Spirulina dry powder production because sea water itself contained carbonate and nitrogen nutrients as well as trace elements necessary for the growth of the algae. 4) Seawater-cultured Spirulina dry powder has a very high protein content, as high as 68.31% (amino acid content, 6286%), low fat content, low ash content (6.4%), and very ow harmful trace element content and is therefore ideal as health food ingredient, food additives, animal feed, etc. The results of this study provide good scientific basis for the commercial sea water mass culture or Spirulina.
