Studenteropgave: Basisprojekt


This project investigates the potential of using waste coffee ground as a substrate constituent
for growing P. ostreatus , both in terms of its efficacy as a medium and with regard to its
availability at Roskilde University. P. ostreatus is grown on three different treatments of
straw, coffee and a mix of both, and evaluated based on substrate mass change, the substrate
C:N ratio, a comparison of the colonisation rate, and a dissection of the colonised substrates.
P. ostreatus is found to grow best on a mixed medium than either material alone, due to a
more favourable C:N ratio and substrate texture. Considering the availability of used coffee at
Roskilde University, and the lack of systematic recycling, the project concludes that reusing
this coffee is an optimal choice for establishing a initial urban mycological garden.
