The purpose of this study is investigated the relationship of algae and bacteria in the seawater, and also want to know the effect of microalgae inhibit bacterial or not. Five species of microalgae, Skeletonema costatum, Chaetoceros muelleri, Tetraselmis chui, Nannochloropsis oculata and Isochrysis galbana were used to study the inhibition of Vibrio alginolyticus growth with microalgae live cell and intracellular products in different concentrations, based on biological characteristic (log phase of growth curve and relationship of cell count and absorbance).
The size of microalgae showed that a negative correlation with the highest cell count in log phase, growth rate was found highest in N. oculata, follow by I. galbana, C. muelleri, S. costatum and T. chui, respectively. All species were found effectively depressed the growth of V. alginolyticus. Moreover, a completely inhibit of V. alginolyticus was found in I. galbana and C. muelleri. On the other hand, different concentrations of S. costatum can inhibit V. alginolyticus growth, only.
