Researchers at Fungi Perfecti will collaborate with environmental engineers at Washington State University to develop a bacteria-eating filter to remove E. coli from storm water.

Posted by Fungi Perfecti - 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.

Posted by Fungi Perfecti - What happened to the name "Agaricus blazei"?

The taxonomy of the mushroom known as Himematsutake or the Royal Sun Agaricus has been confused until recently. The species being grown in China, Japan and Brazil is, in fact, not Agaricus blazei but a new species, now called Agaricus brasiliensis.

Notes on Nutritional Properties of Culinary–Medicinal Mushrooms - International Journal of Medicinal Mushrooms, Vol. 7, pp. 103–110 (2005)

ABSTRACT: Increasingly, mushrooms are being investigated for their role as nutritional foods. However, few studies have been published on their nutritional profi les. The author grew and submitted 20 species for thorough nutritional profiling. In addition, the eff ect of sunlight on the production of vitamin D of indoor-grown mushroom while drying was explored with Lentinus eddoes (Berk.) Singer (shiitake mushroom), Ganoderma lucidum (W. Curt.:Fr.) Lloyd (reishi), and Grifola frondosa (Dicks.:Fr.) S.F. Gray (maitake). Six to eight hours of sunlight exposure stimulated the production of vitamin D from low levels of 134, 66, and 469 IU, respectively, to 46,000, 2760, and 31,900 IU vitamin D, respectively. Th e most vitamin D was produced in Lentinus edodes, whose spore-producing lamellae were exposed to the sun. Dried mushrooms also elicited vitamin D production subsequent to sunlight exposure. Vitamin D is proven as essential for immune function and has now been identifi ed as a major mitigating factor in many diseases, so the sunlight-activated biosynthesis of vitamin D from ergosterols within mushrooms has substantial implications for the mushroom industry in the context of worldwide health.
