RT Journal Article ID 56e0507932c12b54 A1 Beelman, Robert B. A1 Royse, Daniel J. A1 Chikthimmah, Naveen T1 Bioactive Components in Button Mushroom Agaricus bisporus (J. Lge) Imbach (Agaricomycetideae) of Nutritional, Medicinal, and Biological Importance (Review) JF International Journal of Medicinal Mushrooms JO IJM YR 2003 FD 2003-12-01 VO 5 IS 4 OP 18 AB Agaricus bisporus (J. Lge) Imbach is the most widely cultivated species of edible mushroom worldwide. However, it is usually considered to be of lesser nutritional and medicinal value than the other mushrooms grown predominantly in Asia. This paper focuses on bioactive components of nutritional and medicinal importance in A. bisporus, and comparisons will be made to Lentinus edodes (Berk.) Singer (shiitake) and Pleurotus ostreatus (Jacq.:Fr.)Kumm. (oyster mushroom), the second and third most cultivated mushrooms. Data show that A. bisporus mushrooms compare favorably, especially when they are harvested at their fully mature stage, as with portabellas (open cap, brown strain). In addition, the bioactive properties of 1-octen-3-ol and 10-oxo-trans-8-decenoic acid (ODA), natural metabolites of most mushrooms, are discussed. These compounds are formed by the action of lipoxygenase and hydroperoxide lyase on linoleic acid when tissues are damaged or disrupted. Emphasis will be placed on the hormonal properties of ODA that stimulate growth and secondary metabolite production by mycelia, and fruiting body formation from mycelia at low concentrations of the dissociated acid. Also, antimicrobial properties of ODA are demonstrated at higher concentrations and at reduced pH values when this oxo-acid is primarily undissociated.
