Microalgal Products from Agro-industry Wastes
摘要
Industrial production of microalgae requires large volumes of water. Agro-industry wastewaters are generated in large volumes and must be adequately treated. The connection of both processes is only natural—conventional wastewater treatment processes end with a stabilizing pond that has a self-established microbiota, which includes microalgae. This chapter discusses how to use agro-industry wastewaters as culture media, describing the composition of the most common residues, presenting selected examples of microalgal production in effluents, and evaluating how the wastewater composition and the intended microalgal biomass use affects process development. Robust strains or effluent-specific microalgae, screened from the microbiota that develops in wastewaters, can be used in processes that are integrable into agro-industries, preferably after an anaerobic digestion step for high-COD residues.
