Im looking to build a dynamic living sculpture that can be shaped over time - where pieces can be added and removed. I'd like to use fungal mycelium for this and propose inoculating a tower of substrate (autoclaved ag-waste) that has chunks of mycelium mixed in. When the substrate is fully colonised, new agwaste chunks can be "bolted on" using a wire insert that connects the tower with the new piece.
-- The biggest issues I have foreseen are:
1) What fungal species to use? Ive looked into Ecovative Design's technique which is largely a trade secret. Their patents suggest the use of white-rot polyphores like Pycnoporus cinnabarinus. Any suggestions on different species to trial? Im going to try a bunch of different mycelium on a small scale first.
2) How to maintain mycelium dominance over bacterial infection/colonisation? Short of treating the entire substrate with antibiotics to prevent bacterial colonisation of raw substrate I dont see an easy way around this - sterile environment could of course work, but this would be difficult in the hackspace. There is the secondary issue of preventing bacterial infection once the mycelium has colonised the substrate. This I feel could be solved with transgenic mycelium that express various antibiotics, but I have no experience working on such complex fungi, only yeast. Any pointers?
