Article Abstract
Microbial consortium degradation technology can improve the degradation efficiency and adaptability through fungi-bacteria synergism, but the mechanism of the fungi-bacteria interaction is still unclear, making it difficult to optimize the degradation process. The microbial consortium J-6, with high lignin degradation efficiency and strong environmental adaptability, was obtained in our previous research. In this study, the fungi-bacteria interacting mechanism of the microbial consortium J-6 was inferred based on metabolomics technology. The results showed that the positive interaction between fungi and bacteria could improve the efficiency of lignin degradation. The metabolites released by fungi, especially betanidin and ergosterol, had an impact on bacterial metabolism, promoted the degradation of macromolecules, and significantly increased the lignin degradation efficiency. Metabolites released by bacteria, especially L-phenylalanine and taurine, played a key role in fungal metabolism, leading to more complete degradation. The interaction mechanism of chemical currencies exchange between fungi and bacteria during lignin degradation obtained in this study can provide theoretical guidance for microbial consortium degradation technology.

We report the development of a cofactor-free CO fixation platform based on a three-enzyme cascade comprising ferulic acid decarboxylase (AnFDC), phenylalanine ammonia-lyase (AvPAL), and l-amino acid deaminase (PmLAAD). Unlike canonical ATP- or NADPH-dependent CO assimilation pathways, this system uses a prFMN-dependent carboxylation mechanism, enabling efficient CO incorporation under ambient conditions without energy-intensive cofactors. Systematic screening identified AnFDC as the optimal decarboxylase for styrene carboxylation, while AvPAL and PmLAAD were selected for their superior catalytic efficiencies in the cascade.

Host - microbiome interactions are central to Crohn'sdisease (CD) pathogenesis; yet the early metabolic alterations that precededisease onset remain poorly defined. To explore preclinical metabolicsignatures of CD, we analyzed baseline serum metabolomic profiles in a nestedcase-control study within the Crohn's and Colitis Canada - Genetics, Environment, Microbiome (CCC-GEM) Project, a prospective cohort of 5,122 healthyfirst-degree relatives (FDRs) of CD patients. We included 78 individuals wholater developed CD and 311 matched FDRs who remained disease-free.

Peru is the eighth largest producer of cocoa beans worldwide; however, the high cadmium content (Cd) presented in the white Criollo cocoa beans from the Piura region, has limited their commercialization. A potential strategy to mitigate this problem is the application of native lactic acid bacteria (LAB), capable of reducing Cd during the fermentation stage of the grain. Three Theobroma cacao L.
