Anaerobic fermentation of whey : acidogenesis

open access: yes, 1987
Based on the initial exploratory results of single-phase (acidogenesis and methanogenesis takes place in one vessel) whey biomethanation studies, a two-phase (acidogenesis and methanogenesis takes place in two separated serial vessels) biomethanation ...

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

open access: yesEnergy Science &Engineering, Volume 14, Issue 7, Page 3388-3421, July 2026.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Strain‐Specific Biotransformation of Grape Marc by Lactic Acid Bacteria: Genomic Validation and Gut Microbiota Modulation

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
ABSTRACT Grape marc (GM) is a polyphenol‐rich winery byproduct that remains underutilized due to its complex fiber matrix, which limits the bioaccessibility of bound phenolics. While lactic acid fermentation (LAF) can enhance the release of these compounds, the strain‐specific metabolic fate of GM phenolics during digestion and colonic fermentation ...
