    What Is the Stamets P Value® System?

    What Is the Stamets P Value® System?

    An unavoidable fact that affects all life on this planet—including humans and fungi—is that we age. When we are young, the number of downstream cell divisions is vast, but incrementally declines as we grow older. Recently, cell division limiting factors have been attributable to a shortening of telomeres, the protective region at the end of the chromosome, and the role that the enzyme telomerase plays in the repairing and replication of chromosomal DNA. These models serve to explain what we all know: as we age, we become less vital and more susceptible to disease.

    The same is true with mushroom strains. In the 1980's, I developed the proprietary Stamets P Value® system for tracking the age of strains, as measured by their successive growth over a nutrient-filled petri dish. When a strain is first isolated from a mushroom in the wild, and getting the mycelium to grow from the mother mushroom onto a petri dish, it is labeled P-1. After a week or so, the strain will be transferred to a new petri dish which is then designated as P-2, and with each successive transfer, the P Value increases accordingly. This has proven to be an important method for both maintaining strains at peak vitality. The P Value system is key to providing our customers with fungal strains with the greatest efficacy and genetic vitality.

    Mushrooms have immune systems just like people. Over the years, I have received mushroom cultures from fellow mushroom enthusiasts, with no information on their age. Often these cultures would suddenly slow in their growth, become more susceptible to disease or even stop growing altogether. Strains that were progressively cultured from low P Values out-performed the very same strains that had high P Values. The strains that we isolate here at Host Defense are kept close to their wild genetic origins, maintaining exceptional vigor and disease resistance. We are able to keep the P Value low by making sufficient backups of the cultures during the original culturing, and storing pure master cultures under deep refrigeration in our mycological laboratories. In essence, most of our mushroom strains are genetically just a few weeks old, even though some of the rarer strains may have been isolated decades ago.

    In mushroom culture, small mistakes make for big problems. Even today I am surprised at how unfamiliar many culture libraries are with the importance of maintaining young cultures. Amongst the general public, most people do not realize that a small fragment of tissue, the size of your little finger nail, is expanded into hundreds or even thousands of pounds of fungal biomass in a short period of time. Unless the strains have sufficient vitality, they will often fail to produce healthy, vigorous mycelium, containing all the beneficial compounds found in identical strains growing in the wild. What this ultimately means is that the consumer may be getting a product that is far inferior to ones grown from younger strains of mushrooms.

    With Host Defense's nearly four decades of experience, a verifiable chain-of-custody, and the use of stringent quality-assurance tools such as the P Value system, we strive to provide the highest quality products available in the world today. From the Forest, to Our Farm, to You™.

    The BeeFriendly™ Research Initiative

    The BeeFriendly™ Research Initiative

    What Is BeeFriendly?
    BeeFriendlyis a Host Defense® initiative to help reverse the devastating declines in the global bee population that are critically threatening the world’s food security.

    Why Do Bees Need Help?
    In 2015, Colony Collapse Disorder (CCD) rates increased 6% to affect 41% of managed bee colonies nationwide. Some scientists estimate that all managed bee colonies could face total decimation by CCD within five years. Although CCD is not fully understood, it appears to be a destructive synergism of multiple factors. Pathogen (bacterial & viral) infection harms bees already challenged by other stress factors: parasitic mites, pesticides, fungicides and GMO exposure. These stressors of infection, parasitism, toxins, and immune deficits/depression may initiate CCD.

    Why Host Defense?
    Bees need comprehensive immune support to combat the diseases, parasites, and toxins that are driving their decline. Supporting Host Defense means supporting bee recovery research and development.

    Drivers of Colony Decline

    The BeeFriendly™ Research InitiativeMicrobial Viral Pathogens
    Apparently healthy bee colonies may be simultaneously infected by multiple pathogens that are normally held in check by the colony’s immunity. Pathogen infection harms bees already challenged by other stress factors.

    Parasitic Mites
    Varroa mites are parasites that feed on the bodily fluids of bee adults, pupae and larvae. Varroa mites transmit viruses and sap strength from the colony.

    Pesticides, Fungicides & GMO Exposure
    Sub-lethal pesticide exposure can alter bee immunity, behavior, smell, memory, metabolism, flight and mobility, and increase susceptibility to diseases. Exposure to fungicides kills or reduces the beneficial fungi found on pollen, and degrades the nutritional quality of the “bread” that the bees make from it. More research is needed, though many suspect that GMOs may negatively impact bee colonies. 

    The synergistic stressors of infection, parasitism, toxins, and immune deficits/depression may initiate Colony Collapse Disorder (CCD). 

    BeeFriendly Approach to Recovery 

    Immune Support 
    Researching the role that extracts of the mycelium of mushrooms can have in strengthening the immune systems of bees and reducing their viral burden.

    Controlling Bee Parasites
    Developing ways to use the common bio-control fungus Metarhizium anisopliae to control the parasitic mite Varroa destructor. Significantly, this fungus is safe for bees, birds and humans and appears to be highly active against Varroa mites. 

    Detoxification Support
    The bee genome has relatively few detoxification genes compared to solitary insects such as flies and mosquitoes. Select mushroom species release myconutrients that may modulate and up-regulate detoxification pathways in bees.
