Effect of Different Growth Substrates on Selected Nutritional Components of Auricularia auricula Fruit Bodies

The concentrations of selected nutritional components in Auricularia auricula fruit bodies grown on substrates consisting largely of mulberry wood sawdust,pear tree sawdust,or mixed wood sawdust have been determined.Highest levels of total sugar,crude fiber,carbohydrate,flavonoid,Ca and P were recorded in fruit bodies grown with mulberry wood sawdust,whereas total amino acid,Fe,Zn,vitamin B1 and vitamin B2 concentrations were highest in mushrooms grown with pear tree sawdust.Our data demonstrated that sawdust prepared from mulberry wood and pear trees was suitable for inclusion in substrates used to cultivate A.auricula.
