This project was conducted to determine the effect of Pseudomonas fluorescence bacteria on increasing the growth rates of some species of algae namely Chaetoceros Sp., Skeletonema sp., Tetraselmis sp., Chlorella sp.
In this order, the mentioned bacteria were extracted by separator and Zobell 16E media from prawn broodstock ponds, then purified and mass cultured. The algae selected mass, were cultured in Conway media and then these bacteria were investigated at the blooming phase in the several experiments of various treatments in combined culture method. The results revealed that the mentioned bacteria could apply as a partial substitution body of aglae media and it could be used as a new media in various percentages. The results indicated, the very positive effect of bacteria on cultured algae. Therefore, Pseudomonas fluorescense can be used in algae cultured in 50-150 mglit density as a new method for algae culture. This bacterium Could be a new media for Chaetoceros sp., and Tetraselmis sp., but for Skeletonema sp., other percentages of media should be used.
