Abstract

The appropriate antibiotics for Dunaliella sauna purification were initially determined by investigating the effects of several antibiotics on the microalgae and co-occurring bacteria. With the mixture of ampicillin, gentamycin sulfate, cefalotin sodium and streptomycin added in the culture, 800 μg/mL final concentrations respectively, every two days and repeated three times, the bacteria-free algal culture was obtained by spread plate. The microalgae mixed with bacteria grew a little faster than axenic microalgae, but was aging earlier. The microalgae was stimulated to grow faster with isolated co-occurring bacteria added. The results show significance for further study on relationships between microalgae and co-occurring bacteria, as well as genetic engineering. [ABSTRACT FROM AUTHOR]
