Abstract
Pleurotus ostreatus is a well-known edible mushroom species which shows fast growth. The fungus can be used for medical, nutritional, filter, or packaging purposes. In this study, cultivation experiments were carried out with Pleurotus ostreatus growing on polyacrylonitrile (PAN) nanofiber mats in the presence of saccharose and Lutrol F68. The aim of this study was to find out whether modified PAN nanofiber mats are well suited for the growth of fungal mycelium, to increase growth rates and to affect mycelium fiber morphologies. Our results show that Pleurotus ostreatus mycelium grows on nanofiber mats in different morphologies, depending on the specific substrate, and can be used to produce a composite from fungal mycelium and nanofiber mats for biomedical and biotechnological applications.
Highlights
In recent years, electrospinning technology has become more and more popular for the production of nanofiber mats
The experiments showed the highest mycelium growth for environmental temperatures of approximately 25 ◦C, typically resulting in the petri dishes being completely covered with a fine layer of mycelium after 10 days (Figure 2a)
Mykchaylova et al found a dependence of the mycelium morphology of Fomitopsis officinalis on the nutrient medium [56]
Summary
In recent years, electrospinning technology has become more and more popular for the production of nanofiber mats. The possibility to produce textile fabrics out of nanofibers has attracted interest in various areas of science, such as tissue engineering and regenerative medicine, with a rapid increase in recent years [1,2,3,4]. This technology offers several advantages which enable the growth of eukaryotic cells on nanofibrous textiles. Besides applications in tissue engineering, the large surface-to-volume ratio makes nanofiber mats suitable as filters Their high porosity and permeability combined with small pore size allows for reliable filtering of the finest particles [8,9,10]
