【 摘 要 】

Invasive plant species are taking over forests and other ecosystems globally,creating a large reservoir of unused lignocellulolse biomass. In the upper-midwest,buckthorn (Rhamnus cathartica) and honeysuckle (Lonicera maackii) are twoprevalent woody invaders of forest ecosystems. The objective of this study was todetermine if these forest exotics could be successfully used as a sustainablealternative substrate for mushroom cultivation. Since Pleurotus species produce awide array of lignocellulolose degrading enzymes and can break down manydifferent substrates and contaminants, members of this genus were chosen for thestudy. Two strains of the fungus were chosen for this study; one that is used incommercial cultivation practices and one that was isolated from a fruiting bodyfound growing near the invasive plants used in the study. The two strains of oystermushroom were grown on buckthorn and honeysuckle along with controltreatments of oak and straw. Time to colonization, time to first harvest, first yield,total yield, and biological efficiency (BE) were all measured and then compared tothe control treatments. Although both strains of Pleurotus performed best on thestraw substrate, there was no significant difference within a strain of the yield andBE on the buckthorn, honeysuckle, and oak substrates. These results suggest thatinvasive species can provide an alternative sustainable substrate compared tocurrently used hardwood woodchips.
