  1. MW were grown on wheat bran (Bran). 50% of the wheat bran was substituted with autoclaved strawberry vegetative waste (SB-A), strawberry vegetative waste fermented with T. reesei (SB-F), untreated strawberry vegetative waste (SB), autoclaved beans vegetative waste (Bean-A), beans vegetative waste fermented with T. reesei (Bean-F), or untreated autoclaved beans vegetative waste (Bean). Significant differences for each element are expressed with different letters beside the mean values (n = 3, p < 0.05).
