Hydrothermal pretreatment of salvaged cyanobacteria and use of pretreated medium for cultivating Scenedesmus obliquus
This work studied the hydrothermal Pretreatment of Salvaged Cyanobacteria and used the pretreated slurry as medium for cultivating Scenedesmus obliquus. The cyanobacterial slurry was pretreated by chemical oxidation, hydrothermal treatment and hydrothermal oxidation, and then the cultivation experiment of oil-producing microalgae (Scenedesmus obliquus) was carried out. The results showed that hydrothermal oxidation could transform the hard-to-treat salvaged cyanobacteria into culture medium for microalgae. The oil yield from S. obliquus cultured in that was higher than that in conventional BG11 medium.
