GARAY JACOME, María Paula et al. Organic supports: a low-cost alternative to enhance anaerobic digestion?. Rev. ion [online]. 2024, vol.37, n.2, pp.7-24.  Epub Aug 08, 2024. ISSN 0120-100X.  https://doi.org/10.18273/revion.v37n2-2024001.

Organic supports in Anaerobic Digestion facilitate the attachment of microorganisms to the surface of these media, thereby enhancing biogas production; however, the information available in the literature is limited. This article is a compilation of research focused on using organic supports in anaerobic processes published over the past 18 years, highlighting the challenges encountered during anaerobic biodegradation and the limitations of conventional approaches; in this regard, this review concentrates on the influence of organic supports on the microbiology and biochemistry of the anaerobic process. Current trends in using organic supports and their advantages for improving biogas efficiency and quality are also presented.

Keywords : Anerobic digestion; Biofilm; Organic supports; Inorganic supports; Organic waste; Psychrofilic conditions; Biochar; Anaerobic microorganisms; Biogas production; Waste valorization; Methanogenesis; Methane yield.
