碩士 === 國立中央大學 === 化學工程與材料工程研究所 === 98 === Chlorella sp. is a kind of microalgae with many nutrition. It has been produce in commercialize. In recent years, to enhance the biomass and the value of production is important objects.
This thesis had studied in the interaction between Chlorella sp. and Saccharomyces cerevisiae, and the environment factor include carbon dioxide, glucose concentration, pH, and yeast spend cells.
It was found that Chlorella sp. growth and production of polysaccharide were directly proportional to CO2 concentration; In the range of about weak base pH7.4 ~ pH8.4 more suitable for Chlorella sp. growth pH9.0 was slightly lower growth, and pH 6.5 were supressd; 0.125 g/L spent yeast cell promoted Chlorella sp. growth and increase polysaccharide production; the best concentration of glucose that improve Chlorella sp. growth were 1 g/L and 0.5 g/L, among which 1 g/L system were produce the most polysaccharide. By co-culture, we can get more 23% cells, and 1.5 times intracellular polysaccharide and its molecular weight, also we can promoted the activity of IPS 30% than monoculture.
