  • Abstract Scenedesmus obliquus CNW-N, a native algal species obtained from southern Taiwan(Ho et al., 2010) is utilized to cultivate microalgae by using column photobioreactors. Previous studies have indicated that batch culture is not capable to satisfy the requirements of large-scale production of algae. Therefore, this study attempts to develop a semi-continuous culture system to produce large quantity of microalgae using different sources of water, kinds of nutrient and types of methods.
    The microbial contamination is one of the major factors leading to the failure of microalgae cultivation. Chlorination is a cost effective and reliable method in disinfection the medium of microalgae. Thus it has been established a feasible semi-continuous cultivation procedure by using Chlorination as the foundation in the study. The experimental results reveal that using tap water with fertilizer could achieve the best biomass yield: average daily yield is 58.75 mg dry weight/L in the four-day recovery period.
    This article also shows that effluent coming from sewage treatment plant can be used as breeding water whose yield and growth rate is comparable to the tap water with fertilizer farming after disinfection and adding nutrients. But microorganism existing in the effluent cannot be totally removed, so that S. obliquus CNW-N is hardly to re-cultivated. In conclusion, the reliability has been achieved by utilizing a semi-continuous culture system in two types of methods to cultivate mass microalgae at outdoor condition.
