Research ArticleOpen accessEvery word in the titleNanowire Mediated Effect of Interspecies Electron Transfer in Organic Solid Waste Co-FermentationJingkang Chen, Daicheng Liu et al.Low efficiency of Interspecific Electron Transfer (IET) among microorganisms constrains organic matter degradation and biogas production in organic solid waste co‑fermentation. This work investigates the underlying bottleneck and evaluates the nanowire‑mediated enhancement of IET. Surface plasmon resonance‑enhanced electrochemical impedance spectroscopy coupled with metagenomic and metatranscriptomic sequencing was applied to regulate endogenous nanowire formation in anaerobic reactors. Surface Plasmon Resonance-Enhanced Electrochemical … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 9 Oct 2026 · 591 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproved Compost Production from Fruit and Vegetable Market Waste: A Case Study in Bagua, Amazonas (Peru)Juan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Wilfredo Ruiz Camacho, Juan Francisco Robles RuizInadequate management of organic solid waste in municipal markets represents a critical environmental challenge in tropical developing regions, where high humidity (>80%) and elevated temperatures (>25°C) accelerate decomposition, generating leachate and greenhouse gas emissions. In Peru, over 50% of municipal waste is organic, yet less than 20% is valorised through composting, highlighting a substantial technological gap. This study evaluated an … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 11 Aug 2026 · 1,262 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffectiveness of the Anaerobic Haylage Method for Flax Waste Utilization in the Diet of Friesian Holstein CowsRuly Budiono, Joko Kusmoro, Erin Nurinsani Waafi, SukonoThe haylage dry feed fermentation method is one of the methods of preserving grass feed, dried herbs, or dry agricultural waste for animal feed. This study aims to determine the quality of hemp flakes waste that has been dried for 6 months and has a water content of <3% using the Haylage method.
