| Outline of Final Research Achievements |
In this study, it has been observed that secondary metabolite profiles of fungi growing on an interface between a liquid medium and an organic phase (an extractive liquid-surface immobilization system) are drastically different to those gained by conventional submerged, extractive submerged and agar-organic solvent interfacial cultivation systems. The interfacial system are expected as a superior high-throughput screening system for the discovery of new biologically active substances. Indeed, the interfacial screening system yielded a high incidence of antimicrobial activity, with 22% of the fungi tested exhibiting anti fungal activity against an yeast, Pichia anomala.
Furthermore, it has been observed that higher expression of genes relating the biosynthesis of lovastatin compared with those in the traditional submerged and extractive cultivation systems.
