Biodegradation And Feasibility Of Three Pleurotus Species On Cigarette Filters, Raymond Updyke

Honors College

This study was designed to evaluate the biodegradation and feasibility of growing three oyster mushroom species - Pleurotus ostreatus, Pleurotus citrinopileatus, and Pleurotus djamor - on three different cigarette filter waste substrates: intact cigarette filters, blended cigarette filters, and smoked, intact cigarette filters. Cigarette filters are a common waste and are made primarily of cellulose acetate. Oyster mushrooms (Pleurotus spp.) have been shown to degrade synthetic polymers similar to cellulose acetate. In the experiment, the substrates were inoculated with mushroom spawn and placed in a growth chamber maintained at 24° C. After a six-week period, mycelium …
