Abstract

With the increasing emissions into the atmosphere, the concentration of CO2 increased not only in the air but also in the ocean [1]. The greenhouse effect may affect the nutrient content in the ocean as well as the distribution of marine diatoms. The cell size of P. tricornutum is significantly smaller by approximately 15% under N-limited conditions. However, with simulated increased CO2 concentrations (expected by the end of this century), the growth rate was not significantly increased [1]. Brisbane is located in the southeast corner of Queensland, Australia, and has a humid subtropical climate. The minimum mean temperature is 16.6°C and the maximum mean temperature is 26.6°C. East coast sea water temperatures peak in the range of 26°C to 28°C around early February and the lowest in about mid August, in the range 20°C to 22°C. P. tricornutum has been found in several places around the world, typically in coastal areas with wide fluctuations in salinity [2]. Therefore, it is reasonable to consider that the local water system may harbour this species. This part of the research isolated a local strain of P. tricornutum and discovered new properties from it, such as ammonia tolerance. Growth and EPA content comparisons were made between local strains and control strains (Tasmania originated strains).
