【Research Activities】

Microbial ecology in soil, manure, and compost is a major concern in my laboratory. Also, microbial aspects in wastewater treatment are included in the research objects of the laboratory.

Major topics of research are:

1) Development of fluorescence microscopic techniques for visualizing and enumerating bacteria in soil and compost samples by using fluorescence in situ hybridization (FISH), direct viable count (DVC)-FISH, and micro-colony FIFH.

2) Microbial ecology of human pathogenic bacteria and the indicator bacteria in agricultural environments with special reference to the contamination of fresh vegetables grown in hydroponics and soil.

3) Survival of E. coli and salmonellas in hydroponics and soil with special reference to the interaction with protozoa.

4) Microbial ecology of compost.

5) Microbial ecology of wastewater treatment by the Yakult system.

6) Development of pretreatments of wooden materials for biogas production.

7) Application of lipolytic bacteria to wastewater treatment of cooking grease traps

8) Evaluation of microbial agents used for agricultural and environmental purpose by fluorescence microscopy.

9) Microbial ecology including human pathogens in cave environments.

Research and consulting are also conducted to enhance local activities of citizens and private companies for promoting recycle-based society by developing biotechnology for the recycle use (food-waste compost, bio-diesel fuel, biogas production, etc) of biomass resources generated in urban and agricultural communities.

【Message】

Microbial ecology in soil, compost, wastewater treatment and biogas plant will surely provide fundamental biotechnology to promote recycle-based society and sustainable agriculture.

Also deep understanding on ecology of human pathogens in agricultural environments will develop microbial safety of fresh vegetables in organic agriculture. I welcome to my laboratory those students who want to dedicate their time to solving these microbial issues.
