1results about How to "High polysaccharide yield" patented technology

This invention relates to the field of microbial fermentation technology, and particularly to *Phellinus linteus* mycelium, a method for increasing the polysaccharide yield of *Phellinus linteus* mycelium, and their applications. The method involves placing *Phellinus linteus* mycelium in an alternating magnetic field environment with a magnetic field strength of 2 mT to 20 mT and a frequency of 2 Hz to 100 Hz during the late logarithmic growth phase to the early stationary phase of its cultivation. Compared to a control group without magnetic field treatment, this method can increase the intracellular polysaccharide yield of *Phellinus linteus* mycelium by 10%–95%, while maintaining stable or slightly increased mycelial biomass. Furthermore, this method is a purely physical stimulation, introducing no chemical substances into the fermentation system, resulting in no pollution or residue, and aligns with the development direction of green biomanufacturing.
