Towards sustainable food production! "Quality stabilization" of microbial materials.
Efficiently microbial materializing our company's proprietary mycorrhizal fungi! Storage methods for arbuscular mycorrhizal fungi.
The representative arbuscular mycorrhizal fungi coexist with the roots of various crops, absorbing nutrients (especially phosphorus) from the soil and supplying them to the crops. Therefore, they are utilized as environmentally friendly microbial materials to reduce phosphorus fertilizer usage. The current materials are obtained through "co-cultivation," but there are challenges remaining in mass production and quality stabilization, leading to considerations for materialization through "pure culture." Our group has discovered an efficient pure culture method by adding fatty acids such as myristic acid to the medium during the cultivation of parent spores. However, since the microbial materials obtained from pure cultures are stored in refrigeration until they are used in the field, we are investigating production conditions for next-generation spores that can maintain sufficient germination rates even after refrigeration. By adding not only myristic acid but also palmitic acid to the medium, we can approach the germination rates achieved in co-cultivation, which will contribute to the "quality stabilization" following the mass production of microbial materials. [Summary] - Established an efficient pure culture method for mycorrhizal fungi by adding fatty acids to the medium. - Further innovations in the fatty acids added to the medium will lead to the materialization of spores suitable for refrigeration storage. - Technical guidance for materialization towards the unique strains held by various companies, rather than a monopoly on technology by a single company, is possible.
