環境微生物の話【Environmental microbes】

   Many surprise to hear the number of times I am away from my office. I have just attended a conference in Europe and today was in Tokyo, writing this article in a plane. I am so happy to be able to be invited for many meetings and also study at many places, although I have to look after my health. Wherever I go, I realized that the scientific area of environmental biology is rapidly expanding and progressing. Scientists started identifying what sort of microbes are living in what type of environment. However, they are still struggling controlling them and evaluating them, whether they are good or bad. 
   Scientists know that microbes can be beneficial for us, for example, to fertile soils or to mitigate some environmental risks. However, we fail to manage them as we like. 
   We have been talking about this in Tokyo today. We see hundreds of thousands of microbes in a drop of water or a piece of soil particle. However, we never know whether these represent the whole river/lake or farm. We can still evaluate the whole drops of water of a river, until it dries out, but it is unrealistic. 
   Also, our study suggests that microbes are changing every day and night. Thus, they change depending on when we sample the soil. Well, this kind of research is endless but we will understand microbial activity and habitats, more in details in near future. Scientists have to make sure whether these new understandings benefit to create the better world.
