title: Outdoor Growth Characterization of an Unknown Microalga Screened from ContaminatedChlorellaCulture.
abstract: Outdoor microalgae cultivation process is threatened by many issues, such as pest pollution and complex, changeable weather. Therefore, it is difficult to have identical growth rate for the microalgae cells and to keep their continuous growth. Outdoor cultivation requires the algae strains not only to have a strong ability to accumulate oil, but also to adapt to the complicated external environment. Using 18S rRNA technology, one wild strainScenedesmussp. FS was isolated and identified from the culture ofChlorella zofingiensis. Upon contamination byScenedesmussp., the species could quickly replaceChlorella zofingiensisG1 and occupy ecological niche in the outdoor column photobioreactors. The results indicated thatScenedesmussp. FS showed high alkali resistance. It also showed that even under the condition of a low inoculum rate (OD680, 0.08),Scenedesmussp. FS could still grow in the outdoor raceway pond under a high alkaline environment. Even under unoptimized conditions, the oil content ofScenedesmussp. FS could reach more than 22% and C16-C18 content could reach up to 79.68%, showing that this species has the potential for the biodiesel production in the near future.
