Accurate near-threshold model for ultracold KRb dimers from interisotope Feshbach spectroscopy

, 2008
We investigate magnetic Feshbach resonances in two different ultracold K-Rb mixtures. Information on the K(39)-Rb(87) isotopic pair is combined with novel and pre-existing observations of resonance patterns for K(40)-Rb(87).

Phenotypic responses to interspecies competition and commensalism in a naturally derived microbial co-culture [PDF]

, 2018
The fundamental question of whether different microbial species will co-exist or compete in a given environment depends on context, composition and environmental constraints.

Research progress and perspective on sludge anaerobic digestion technology: A bibliometric analysis

Water Science and Technology
Rational disposal of sludge is an ongoing concern. This work is the first attempt for in-depth statistical analysis of anaerobic digestion (AD) research in recent three decades (1986–2022) using both quantitative and qualitative approaches in ...

Conductive materials stimulated direct interspecies electron transfer and application in anaerobic digestion [PDF]

, 2019
Methanation of complex organic substances needs cooperation between syntrophic microorganisms. During this process, electrons and protons or other reducing equivalents are transferred from bacteria to archaea by intermediate shuttles, such as hydrogen. However, this process cannot be completed unless intermediates are readily removed.

Granular Activated Carbon and Organic Loading Interactions in Methane Fermentation: An Inverse Load-Dependent Relationship and Absolute Microbial Abundance Analysis

Fuels
This study addresses volatile fatty acid (VFA) accumulation, a key issue limiting methane fermentation under high organic loading rate (OLR) conditions. Batch experiments were conducted with GAC (0–10%) under various OLRs (1:0.5–1:10) to investigate its ...

Benefits of conductive additive for direct interspecies electron transfer in anaerobic digestion

Frontiers of Environmental Science & Engineering
Abstract Conductive additive such as biochar have been extensively employed to enhance anaerobic digestion (AD) performance for over a decade. Among the proposed mechanisms, conductive additive-facilitated direct interspecies electron transfer (DIET) is frequently cited as a key contributor to these performance improvements.
