This collection comprises a kimchi metagenomic dataset and an genomic dataset of bacterial strains isolated from the same food samples. The metagenomic dataset is a time monitoring (from 3 to 28 days of fermentation) of Natural Napa Cabbage Kimchi performed at lab-scale according to traditional Korean recipe. Two batches of samples were analysed with (4%) or without garlic to study the impact of this ingredient on Microbial communities. For each sample, culturomic of bacteria were performed to identify the strain's diversity during the fermentation. High quality genomic data (hybride nanaopore+illumina) assemblies of the strains' genomes are part of the second genomic dataset released in this collection. These two datasets were produced in the Frame of the Horizon Europe RIA project DOMINO (Harnessing the potential of fermentation for healthy and sustainable foods; https://www.domino-euproject.eu/; grant agreement 101060218) as part of the case-study linked to fermented vegetables (WP4). The tabulated files below summarize all accession numbers and metadata associated with the samples and strains genome assemblies.
