Stimulating volatile fatty acid production in anaerobic digestion: Bacterial co...
Hoffmann, Nicolás; Ciudad, Gustavo; Fincheira, Paola; Rodriguez, Rodrigo; Vergara, Christian; Tortella, Gonzalo; Durán, Paola; Braga, Cátia Sofia NevesThe production of volatile fatty acids (VFA) through anaerobic digestion has gained significant attention due to its potential benefits for renewable energy, biofuel production, waste valorization, bioproduct synthesis, and wastewater treatment. Nano-zero valent iron (nZVI) and magnetite nanoparticles (FeO-NPs) have been identified as effective nanomaterials for enhancing methane production, although their appl...
Challenging the conductive paradigm: The unexpected role of sand in anaerobic d...
Hoffmann, Nicolás; Braga, Cátia Sofia Neves; Rubilar, Olga; Ciudad, Gustavo; Tortella, Gonzalo; Hermosilla, Edward; Duarte, Maria SaloméThe application of conductive materials (CM) has emerged as a strategy to enhance methane production (MP) in anaerobic digestion (AD) systems. This study highlights the potential of sand as an alternative to CM for biomethane production during AD, utilizing complex microbial communities and pure cultures of methanogens. Sand (non-CM) was compared with activated carbon (AC) and nano-zero valent iron (nZVI), both...
