The main objective of the ongoing project is to create a scientific basis for culturing Adriatic microalgae on industrial wastewater, and to evaluate capacity of wastewaters from INA-oil refinery plant as for co-generative production of 3rd generation biofuels. The goal is to provide economic benefits to the oil production process while taking care of decreasing the environmental pollution. The methodology for selection of the most suitable microalgae species indigenous to northern Adriatic and associated heterotrophic bacteria, will be explored for production of biorefinery feedstock.
