AI Article Synopsis
- Anaerobic fungi in herbivores' guts work with methanogenic archaea to break down plant material, showcasing potential for bioconversion industries.
- This study identified three co-cultures of Piromyces and Methanobrevibacter ruminantium from yaks on the Qinghai Tibetan Plateau, with one co-culture (Yak-G18) showing exceptional polysaccharide degradation capabilities, particularly xylanase production.
- The Yak-G18 co-culture demonstrated a strong ability to degrade lignocellulosic substrates and produce valuable metabolic byproducts like methane and acetate, indicating its usefulness in converting biomass for industrial applications.
Article Abstract
Anaerobic fungi reside in the gut of herbivore and synergize with associated methanogenic archaea to decompose ingested plant biomass. Despite their potential for use in bioconversion industry, only a few natural fungus-methanogen co-cultures have been isolated and characterized. In this study we identified three co-cultures of Piromyces with Methanobrevibacter ruminantium from the rumen of yaks grazing on the Qinghai Tibetan Plateau. The representative co-culture, namely (Piromyces + M. ruminantium) Yak-G18, showed remarkable polysaccharide hydrolase production, especially xylanase. Consequently, it was able to degrade various lignocellulose substrates with a biodegrading capability superior to most previously identified fungus or fungus-methanogen co-culture isolates. End-product profiling analysis validated the beneficial metabolic impact of associated methanogen on fungus as revealed by high-yield production of methane and acetate and sustained growth on lignocellulose. Together, our data demonstrated a great potential of (Piromyces + M. ruminantium) Yak-G18 co-culture for use in industrial bioconversion of lignocellulosic biomass.

Consortium-based approaches are a promising avenue toward efficient bioprocessing. However, many complex microbial interactions dictate community dynamics and stability that must be replicated in synthetic systems. The rumen and/or hindguts of large mammalian herbivores harbor complex communities of biomass-degrading fungi and bacteria, as well as archaea and protozoa that work collectively to degrade lignocellulose, yet the microbial interactions responsible for stability, resilience, and activity of the community remain largely uncharacterized.

Anaerobic fungi are potent lignocellulose degraders, but have not yet been exploited in this capacity, largely owing to their poor metabolic characterization. In the current study, a time course of fermentation was conducted to study the effect of the co-cultured methanogens on xylose metabolism by anaerobic fungi. The fermentation end-products from anaerobic fungal monoculture were H (6.

Although the scheme of metabolic pathways involved in the production of the major end products has been described, the dynamic profile of metabolites of anaerobic fungi co-cultured with methanogens is limited, especially for the intermediate metabolites. In the present study, the fermentation of the co-culture of Piromyces sp. F1 and Methanobrevibacter thaueri on glucose was investigated.

Aim: To obtain co-cultures of anaerobic fungi and their indigenously associated methanogens from the rumen of yaks grazing on the Qinghai-Tibetan Plateau and investigate their morphology features and ability to degrade lignocellulose.
Methods And Results: Twenty fungus-methanogen co-cultures were obtained by Hungate roll-tube technique. The fungi were identified as Orpinomyces, Neocallimastix and Piromyces genera based on the morphological characteristics and internal transcribed spacer 1 sequences analysis.
