EVALUATION OF UNCONVENTIONAL CULTURE MEDIA FOR THE PRODUCTION OF INTEREST COMPOUNDS BY Scenedesmus obliquus AND Chlorella vulgaris
Resumen
The study of the cultivation of microalgae Senedesmus obliquus and Chlorella vulgaris is proposed using culture media prepared with digestates and vermicomposts to produce compounds of interest for application in industries such as food, cosmetics and energy, among others. These compounds are proteins, carbohydrates, pigments and lipids. The development of processes using microalgae cultivated in alternate culture media will bring many environmental advantages: 1) Manure that is usually stored in the open air, contaminating soil, water and soil and generating significant amounts of greenhouse gases will be used; 2) Manure under anaerobic digestion and vermicomposting processes is transformed into fertilizers that can be used for the cultivation of microalgae, thus preventing the use of synthetic culture media. To obtain the components of synthetic culture media, chemical processes are used, which require energy and water consumption and produce polluting waste. 3) High-value products are obtained for use in various industries, such as proteins, pigments, carbohydrates, and lipids. Obtaining these products through microalgae cultivation requires lower energy costs, without the use of polluting compounds such as cartridges, and with biodegradable waste.
