Usually white, the pearl oyster could also be gray or brown and sometimes will even show off vibrant blues in the right conditions. It is probably the most common oyster mushroom, and it is of great interest to Mushy Farms because it can grow on many different waste substrates like grass, leaves, paper, cardboard, straw, wood, corn cobs, stalks, stems, dead trees, composts, and many other agricultural/ societal wastes.

Pleurotus Ostreatus, A Cold Pasteurization Candidate!
We believe cold pasteurization techniques, employing waste materials as a bulk substrate, are a promising field of study for solving world hunger and poor nutrition issues! In our studies the pearl oyster has shown the ability to produce relatively large yields with very little energy needs on agricultural/ land wastes.
Anti-Cancer? Cancer Prevention? You be the judge…
Evaluated whether extracts from edible mushrooms Agaricus bisporus (portabella), Flammulina velutipes (enoki), Lentinula edodes (shiitake) and Pleurotus ostreatus (oyster) affect the growth of breast and colon cancer cells. Here, we identified as the most potent, P. ostreatus (oyster mushroom) which suppressed proliferation of breast cancer (MCF-7, MDA-MB-231) and colon cancer (HT-29, HCT-116) cells, without affecting proliferation of epithelial mammary MCF-10A and normal colon FHC cells.

Individuals who eat two medium-sized mushrooms daily have a 45 per cent lower risk of cancer compared to those who do not eat mushrooms, according to Pennsylvania State University research, published in Advances in Nutrition.

Osteoporosis?
Oyster Mushrooms Can Reduce Osteoporosis Risks
Oyster mushroom is selected as the object of their study because it is known to contain lovastatin which is known as an alternative inhibitor of osteoclastogenesis process because it can increase osteoblast differentiation and inhibit osteoclastogenesis.
