Genome-based evaluation of safety and probiotic properties of Lactobacillus plantarum Lrld-22

Liu, D. and Zhang, Z. M. and Qin, Y. Q. and Zhao, H. Y. and Liu, G. and Ye, M. and Liu, X. H. (2025) Genome-based evaluation of safety and probiotic properties of Lactobacillus plantarum Lrld-22. International Food Research Journal (Malaysia), 32 (1). pp. 252-263. ISSN 2231 7546

Lactobacillus plantarum is a widely distributed and significant probiotic species. A strain, L. plantarum Lrld-22, was isolated from traditional fermented yak dairy products in Qinghai province. The whole genome of Lrld-22 was sequenced, and the sequence result was assembled into a 3,246 Mbp sketch genome. Two plasma sequences of 81,471 and 41,833 bp were detected. The Lrld-22 genome was made up of a single circular chromosome, measuring 3,246,150 bp and containing 3,284 genes, 99 uncoded RNAs, and a number of repetitive sequences. The genome had a GC content of 44.58%, and no prophage region was detected. Functional annotation revealed a large number of the genes involved in carbohydrate and fatty acid metabolisms, suggesting that L. plantarum Lrld22 could have enhanced capabilities for carbohydrate and fat utilisation.

Abstract

Lactobacillus plantarum is a widely distributed and significant probiotic species. A strain, L. plantarum Lrld-22, was isolated from traditional fermented yak dairy products in Qinghai province. The whole genome of Lrld-22 was sequenced, and the sequence result was assembled into a 3,246 Mbp sketch genome. Two plasma sequences of 81,471 and 41,833 bp were detected. The Lrld-22 genome was made up of a single circular chromosome, measuring 3,246,150 bp and containing 3,284 genes, 99 uncoded RNAs, and a number of repetitive sequences. The genome had a GC content of 44.58%, and no prophage region was detected. Functional annotation revealed a large number of the genes involved in carbohydrate and fatty acid metabolisms, suggesting that L. plantarum Lrld22 could have enhanced capabilities for carbohydrate and fat utilisation.
