【 摘 要 】

Synergetic bacteria need to be explored which can accelerate the growth of microalgae which have potential as oil producer related to renewable energy. This research aimed to analyze the influence of the dominant bacteria from Ranu Pane (POD code), Ranu Grati (GOD code), Ranu Regulo (ROD code), and the recombinant dominant bacteria from all sampling areas (PGR code) on the growth of Chlorella sp. in co-culture. Also, the individual crosscheck was done by making co-interaction between the predominant bacteria from each and biofuel producing microalgae (Chlorella sp.). The co-culture data between the dominant bacteria species and Chlorella sp. showed that dominant species had different effects on the number of microalgae cells in the co-culture. Thus, co-culture could accelerate the growth of Chlorella sp, extend the log and stationary phases and enhance the environmental carrying capacity.
