PLoS ONE 14(5):Įditor: Kandasamy Ulaganathan, Osmania University, INDIA It provides an innovative strategy for easy, reliable, and low cost maintenance of materials containing living fungal mycelium.Ĭitation: Chang J, Chan PL, Xie Y, Ma KL, Cheung MK, Kwan HS (2019) Modified recipe to inhibit fruiting body formation for living fungal biomaterial manufacture. This is the first report of using a GSK-3 inhibitor to suppress fruiting body formation in living fungal mycelium-based materials. We suggest the inclusion of GSK-3 inhibitors in the cultivation recipes for inhibiting fruiting body formation and regulating mycelium growth.

Sensitive windows to these inhibitors throughout the fungal life cycle were also identified. The concentrations of glycogen synthase kinase-3 (GSK-3) inhibitors, such as lithium chloride or CHIR99021 trihydrochloride, were found to directly correlate with the development of fruiting bodies in the mushroom forming fungi such as Coprinopsis cinerea and Pleurotus djamor. The objective of this study was to provide a biochemical solution to regulate the fruiting body formation, which may replace heat killing of mycelium in practice. Suppression of fruiting body formation is also a useful tool for maintaining the stability of a mycelium-based material with ease and lower cost. Increasing FAE can also help reduce condensation collecting on the casings but try not to let it comprimise the RH.Living fungal mycelium with abolished ability to form fruiting bodies is a self-healing substance, which is particularly valuable for further engineering and development as materials sensing environmental changes and secreting signals. I'd remove the excess moisture on the trays if any,and keep RH around 93% and see how they react for a day or two and adjust accordingly. It looks more like metabolites than contam. You can also take the trays and tilt them to see if water runs out.īe sure to wear a sterile glove to keep your hand on the sub so it don't fall out,and then use the paper towl to soak up any exscess on the surface You can take paper towl and let the paper towl soak up any excess water. Can you suggest any possible ways to save them?' 'After an UH malfunction last night they got soaked. (image taken from shroomery for educational purpose) The 2nd pic looks worse than the 1st as far as possible overlay. I rotated and circled spots on your pics to show hyphal knots and what they look like. Not sure if the sparkling effect is water,flash from the camera or hyphal knots,but if they are there before the pic and there is no heavy condensation on the casing then it only leads one to think of hyphal knots. In your pics I see hyphal knots in places. Make sure you hydrogmeter is working correctly.Īnother trick is to use paper towel and very very gently pat the casing One way to help the condensation on your trays is to increase F.A.E,you may also need to readjust you RH. Just try to keep your RH up as much as possible around 93 - 97%(for cased grain) The two behind your temp/ rh gauge also have what appear to be hyphal knots,but those two are looking close to overlay which isn't good.īut I'd like to see closer up of them as well because they look like they may have hyphal knots also.Ĭased grains start fruiting anywhere the 14th - 21st day after cased.ĭunked and rolled cakes can take 3 - 4 weeks to show fruit. I'd like to see them a bit closer up because I thought I saw a couple spots that looked like primordia,a.k.a hyphal knots. From what I can see in the pic,the 3 trays that are more casing than mycelium look fine.
