内容記述
We performed functional genomics of lactic acid bacteria, Lactobacillus paracasei strain LC-Ikematsu, using two next-generation sequencers 454 GS Junior (Roche) and MiSeq (Illumina). The genome sequences were assembled using a GS De Novo Assembler (Roche), resulting in 87 contigs (>500 bp) and a total contig length of 3,078,383 bp. The assembled genome sequence was predicted to contain many more amino acid metabolism genes than those of the other Lactobacillus species. Reconstruction of the metabolic pathways using the Kyoto Encyclopedia of Genes and Genomes database suggested that LC-Ikematsu could potentially biosynthesize nine amino acids. The amino acid requirements of LC-Ikematsu were examined using various modified versions of the complete chemically defined medium deficient in specific amino acids. Consequently, we elucidated that LC-Ikematsu could synthesize seven amino acids. This study also establishes bioinformatics techniques for the analysis of bacterial characteristics, which could be effectively applied to other microorganisms.
