Microbial succession and interaction in vacuum-packed beef: a longitudinal study of bacterial and fungal dynamics.
Article in NPJ science of food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The microbial dynamics of vacuum-packed (VP) beef are shaped by interactions between bacterial and fungal communities, influencing spoilage and meat quality during storage. While bacterial succession is well studied, fungal roles remain underexplored. We examined microbial communities in VP beef over 85 days using spike-in, qPCR, 16S/18S rRNA gene amplicon sequencing, culture-based methods, whole genome sequencing, and co-culture experiments. Initially dominated by Pseudomonas and Brochothrix, the bacterial community shifted toward lactic acid bacteria (LAB) by day 15. Fungal communities remained diverse, with Kurtzmaniella, Barnettozyma, Debaryomyces, and Yarrowia as key genera. Co-culture experiments revealed a triangular interaction: yeasts enhanced LAB, LAB inhibited Enterobacterales, and Enterobacterales suppressed yeasts. Genomic analyses suggest yeast metabolites support LAB, LAB inhibit via acids and bacteriocins, and Enterobacterales produce fungal cell wall-degrading enzymes. These findings highlight fungi's overlooked role and the importance of inter-kingdom interactions in meat microbiomes, offering a foundation for strategies to improve meat safety and shelf life.
