Abstract

Molecular technologies, including high-throughput sequencing, have expanded our perception of the microbial world. Unprecedented insights into the composition and function of microbial communities have generated large interest, with numerous landmark studies published in recent years relating the important roles of microbiomes and the environment-especially diet and nutrition-in human, animal, and global health. As such, food microbiomes represent an important cross-over between the environment and host. This is especially true of fermented food microbiomes, which actively introduce microbial metabolites and, to a lesser extent, live microbes into the human gut. Here, we discuss the history of fermented foods, and examine how molecular approaches have advanced research of these fermented foods over the past decade. We highlight how various molecular approaches have helped us to understand the ways in which microbes shape the qualities of these products, and we summarize the impacts of consuming fermented foods on the gut. Finally, we explore how advances in bioinformatics could be leveraged to enhance our understanding of fermented foods. This review highlights how integrated molecular approaches are changing our understanding of the microbial communities associated with food fermentation, the creation of unique food products, and their influences on the human microbiome and health.

  • Shotgun metagenomics is the sole approach able to comprehensively survey the microbial composition of a sample and unearth its genomic potential along with the reconstruction of genomes of multiple strains.

    “While cultivation has extended to high-throughput settings, 14 shotgun metagenomics is the sole approach able to comprehensively survey the microbial composition of a sample and unearth its genomic potential 12,15 along with the reconstruction of genomes of multiple strains. 16,17”

    From Unexplored microbial diversity from 2,500 food metagenomes and links with the human microbiome. (2024) · cites this paper as [17]

    The Introduction’s “High-throughput sequencing approaches” section says shotgun metagenomics provides a microbiome functional profile and that long-read methods can recover strain-resolved genomes. It does not call shotgun metagenomics the sole approach, and it cautions that strain-level analysis is often limited to dominant species and that separating mixtures of strains remains challenging.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
