| 摘要 |
<p>The invention relates to a process for continuously growing algae while obtaining a biofuel, biocarbon and an algal extract with complex effects on crop plants. According to the invention, the process consists in continuously growing microalgae in a system comprising two cascade-operating photo-bio-reactors, in autotrophic - mixotrophic cycle, separating the grown algal biomass from the growth media by electro-flocculation and flotation, extraction of lipids which are further subjected to transesterification into biofuel, the recovered liquid medium being then mixed with the recovered raw glycerine and the autotrophic biomass hydrolysates, resulting in a mixture to be used in the mixotrophic culture of algae, wherefrom the enzymatic hydrolysis-resistant biomass is converted into biocarbon to be used in the purification of the recovered liquid medium which is further completed with mineral nutrients and used in the process, in the end, an enzymatic extract with complex effects on crop plants being obtained from the mixotrophic biomass.</p> |
