Research

This laboratory focuses on finding, clarification, and application of superior microbial systems. These research subjects are carried out by molecular biology (functional analysis of genes and enzymes/proteins), cell biology (electron and fluorescence microscopy), structural biology (X-ray crystallography), and synthetic biology (metabolite and gene-expression analysis) including omics biology (genomics, transcriptomics, proteomics, metabolomics).

The recent research subjects are as follows:

1. Microbial systems for interaction with animal (human) and plant
