Influence of Food Waste Compost on the Yield and Mineral Content of Ganoderma lucidum, Lentinula edodes, and Pholiota adipose Fruiting Bodies.

The objectives of this study were to evaluate applicability of food waste compost (FWC) as a substrate for cultivation of Ganoderma lucidum, Lentinula edodes, and Pholiota adipose, and to determine contents of Ca, Mg, Na, and K in fruiting bodies (FB). FB yield per substrate in FWC-free controls was 53 ± 4 g/kg for G. lucidum, 270 ± 90 g/kg for L. edodes, and 1,430 ± 355 g/kg for P. adipose. Substrates supplemented with FWC showed the highest FB production at FWC content of 10% for G. lucidum (64 ± 6 g/kg), and 13% for L. edodes (665 ± 110 g/kg) and P. adipose (2,345 ± 395 g/kg), which were 1.2~2.5 times higher than the values for the controls. P. adipose contained higher amounts of mineral elements than the other species. Ca, Mg, Na, and K content in FB did not show a significant relation to FWC content.
