JAPANESE SITEMAP

Filamentous fungi or mold live everywhere in Japan . Filamentous fungi are hated because they damage foodstuff, such as bread, rice cake and grow under the humid condition, making environment uncomfortable or nasty. On the contrary, filamentous fungi are recognized as important organisms because they have been used for fermentation industry to make Japanese sake, soy sauce in Japan and cheese in Europe .

  Moreover filamentous fungi also contributed to the development of medical technology since the discovery of antibiotic PenicillinE in 1929 as a resource for screening and/or a tool for mass production of physiological compounds such as antibiotics, anticancer drug because they show high productivity of secondary metabolites.

   As a result of advanced genome analysis by genetic technology, it was revealed that filamentous fungi have ability to produce as many as 50 different compounds and are promising resources for discovery of novel compounds. Nowadays new bioactive compounds are highly demanded because of the emergence of novel pathogens, multidrug resistance bacteria and novel diseases. Making the most of the bioresource will bring about huge benefits to the life of human being.

    We consider filamentous fungi as bioresources having infinite possibility and aim to contribute to the society by applying them efficiently.

  • Search for novel bioactive compounds produced by filamentous fungi.
  • Identification of biosynthetic genes for bioactive compounds and analysis of the regulatory mechanism for their expression.
  • Construction of heterologous production system of fungal bioactive compounds
  • Synthesis of novel compounds by genetic techniques.
  • Molecular breeding by genetic technology.
