| The growth characteristic of a predominant planktonic blooming species, Mallomonas elongata in a small shallow eutrophic pond was investigated In the field (from October 2004 to September 2005) and laboratory, Dense blooming (max. 17,600 cells $mL^{-1}$) of this silica-scaled chrysophytes was observed for a short time period in early spring (water temperature 12-$18^{circ}C$ and pH 8.4-9.5), The growth characteristics of M. elongata isolated from this pond was investigated at various temperatures and pH under batch culture. The unialgal culture of M. elongata showed maximum growth rate (${mu}max$) at $15^{circ}C$ similar to the natural conditions. However, the optimal pH of the isolated batch culture was lower than the pond water pH at which M. elongata appeared in large population density. |
