Abstract
The cultivation of heterotrophic and phototrophic micro-organisms is integrated for the production of bio-oil for biofuels, wherein the overall algal suspension produced is first thickened, with recirculation of the excess water to cultivation containers, and then thermally treated at a high temperature. After cooling, a bio-oil phase is recovered together with a suspension rich in soluble carbohydrates and proteins which forms a nutritional/energy source for heterotrophic micro-organisms.
