Item Estudios de Chlorella spp en Colombia Revisión sistemática: Métodos de cultivo y sus aplicaciones(Universidad Santiago de Cali, 2022) Banguera Obando, Julián; Varela Santiago, Daniel; Caicedo Bejarano, Luz Dary; Ortiz, SantiagoThe world's population is constantly increasing, and it is expected that by the year 2050 there will be approximately 9 billion people. Industrialization, pollution, consumption of food, energy, and greenhouse gases, is a problem that must be faced with the commitment to reduce carbon dioxide by 50% to 80%, which would allow preserving climate and food security. In Colombia, the cultivation of microalgae has already been implemented in several industrial sectors, agribusiness, the agricultural sector and in the environmental area. The species of the Chlorella genus are among the most used in the country, to supply consumption needs and for wastewater treatment, due to their capacity to bioaccumulate and biodegrade heavy metals, herbicides, phenols, among other compounds, which is why they are used in phycoremediation processes. It has also been used in research based on the fixation of atmospheric carbon dioxide with positive results. To know the biotechnological use of microalgae in Colombia, a systematic review of the species of Chlorella spp. was carried out to know the cultivation conditions and applications of these microalgae on a national scale. The alternative use of Chlorella spp. is effective compared to other conventional processes used in multiple applications and good results are obtained under correct cultivation conditions. The information obtained in the selected articles offers some bases for the continuity and improvement in applications such as phycoremediation, protein production, biofuels, pigments, among others. The most used Chlorella species in Colombia, such as C. vulgaris and C. sorokiniana, and the multiple cultivation conditions are also presented, establishing that there is no standardization in these processes that would allow achieving the maximum use on an industrial scale of this promising group of microalgae.
