16S-Metagenomic data profiling of the bacterial community in ready-to-eat vegetable salads sold in Kampala, Uganda

Abstract

This article presents a dataset on bacterial community structure associated with Ready-to-eat (RTE) vegetable salads sold in Kampala City, Uganda. The Illumina Miseq sequencing of 16S rRNA gene amplicon unveiled the bacterial communities and generated a metagenomic library from RTE vegetable salads to understand the diversities and distribution. The metagenome contained a total of 23,805 sequences with 35,420 Taxonomic units (OTUs). Metagenome sequence information is obtainable at NCBI under the Bioproject assigned accession number PRJNA1064313. Taxonomic hits distribution from VSEARCH analysis at phylum level classification of NN-3 discovered predominantly Proteobacteria (65.34%) followed by Firmicutes (31.60%) and Bacteroidota (0.14%). Deinococcota (0.01%) and Planctomycetota (0.01%) were also detected. Also, VSEARCH-assisted analysis of NN-4 detected a higher prevalence of Firmicutes (65.68%) than Proteobacteria (33.25%), while Bacteroidota (0.04%) indicating the presence of contaminants of faecal sources.
