Growth of Pleurotus ostreatus on different textile materials for vertical farming

The mycelium of the edible mushroom Pleurotus ostreatus can be used for diverse technical applications, such as packaging materials or wastewater treatment, besides the more obvious use for nutrition. While P. ostreatus usually grows on sawdust, wood or similar materials, a former study investigated mycelium growth on different nanofiber mats. Here, we report on growing P. ostreatus on fabrics knitted from different materials, enabling the use of this mushroom in textile-based vertical farming. Our results underline that P. ostreatus grows similar on natural fibers and on synthetic fibers. The agar medium used to provide nutrients was found to support mycelium growth optimally when applied by dip-coating, suggesting that, in this way, P. ostreatus can also be grown on vertically aligned textile fabrics for vertical farming.
