Thermophilic Lignocellulose-degrading Composting SynCom

Community ID CommunityMech:000282
Ecological State ENGINEERED
Environment manure composting
ENVO:00002170

A five-member thermophilic lignocellulose-degrading synthetic microbial community (SynCom) designed for manure composting, comprising the bacteria Bacillus cereus, Achromobacter sp., and Pseudomonas sp. together with the fungi Cladosporium sp. and Trichoderma harzianum. Inoculation drives a metabolic reprogramming from a biofilm-dependent defense-survival mode toward an active motility-metabolism mode (depleted lipopolysaccharide biosynthesis, enriched flagellar assembly), which restricts horizontal gene transfer opportunities. By intensifying thermophilic fermentation, lowering the carbon/nitrogen ratio, and enhancing humification, the SynCom attenuates antibiotic resistance genes and virulence factors, collapses high-risk ARG-mobilome interactomes, and achieves deep bio-sanitization by eliminating high-risk pathogens such as Pseudomonas aeruginosa.

Growth Media

Thermophilic manure-composting substrate (solid-state)

Temperature thermophilic (no numeric value reported in the abstract) °C

Preparation notes: The SynCom is applied to a solid-state manure-composting matrix and drives intensified thermophilic fermentation with a rapid decrease in carbon/nitrogen ratio and enhanced humification. The abstract (source is closed-access, no legal OA full text) reports only a qualitative thermophilic regime; no numeric temperature, pH, medium composition, atmosphere, or incubation time is stated.
