Summary
Optimal Inonotus obliquus strains were identified for cultivation and industrial production. The Finnish birch strain exhibited the strongest antagonism and abundant nutritional components, making it suitable for exploitation.
Area of Science:
- Mycology
- Plant Science
- Biotechnology
Background:
- Inonotus obliquus, a medicinal mushroom, is valuable for its bioactive compounds.
- Strain selection is crucial for optimizing cultivation and component extraction.
- Understanding genetic and breeding potential is key for industrial applications.
Purpose of the Study:
- To screen and identify superior Inonotus obliquus strains for large-scale cultivation.
- To evaluate strains based on antagonistic properties and nutritional content.
- To determine suitability for industrial production, genetics, and breeding.
Main Methods:
- Inonotus obliquus mycelia from diverse geographical origins were utilized.
- Antagonism assays against Penicillium were performed to screen high-quality strains.
- Proximate analysis (crude fat, ash, protein, fiber) was conducted.
Main Results:
- The Finnish birch Inonotus obliquus strain displayed the strongest antagonism (53.27 mm mycelial diameter).
- Finnish birch strains showed high crude fat (1.93%) and crude protein (20.23%).
- Other strains varied in crude ash (JL04: 8.76%, NBRC8681: 6.8%) and crude fiber (HLJ01: 45.09%, MAFF420101: 38.27%).
Conclusions:
- Inonotus obliquus strains from Finnish birch, HLJ01, and JL04 are recommended for further exploitation.
- These selected strains possess desirable traits for cultivation and industrial applications.
- The study provides a basis for genetic improvement and breeding programs.
