Objective: Prepare a versatile nutritional medium for mushroom cultivation.
 
Materials: Flat jar, wadding, agar-agar, malt extract powder, marker, distilled water, pressure cooker, precision scale (0,1 g), aluminum foil.
 
<u>Step 1: Calculate Ingredient Ratios</u>

<u>Step 2: Weigh Ingredients And Mix Into Flask</u>
 
* Use a scale to measure the required ingredients accurately.
* Construct a container using clean aluminum foil or paper.
* Combine the ingredients in a flask or jar, ensuring thorough mixing.
* Create a hole in the lid and insert cotton wadding to enable pressure cooking and facilitate air exchange for the mushrooms.
* Pour enough of the mixture into each container to cover the bottom adequately. (A thicker agar layer consumes more materials but prevents drying during long-term fridge storage.)
* Seal the jars and cover the lids with aluminum foil to prevent microbes from reaching the air filter later on.
 
<u>Step 3: Sterilize In Pressure Cooker</u>
 
* Add a few centimeters of water into the pressure cooker, ensuring the vessels are submerged but not floating. Close the cooker and reach the designated temperature and pressure point (121°C, 15 PSI). (Avoid using airtight containers in the pressure cooker to prevent bursting; always refer to the pressure cooker manual for proper usage.)
* Reduce the heat to maintain a gentle boil and keep it at the minimum temperature to ensure the water continues to boil.
* Wait for 40 minutes from the point when pressure and heat are reached.
* Turn off the heating source and allow the cooker to cool down naturally. HINT: Avoid releasing pressure suddenly as it may cause the medium to overboil.
* Once the cooker is slightly warm, release the remaining pressure (there should be none), open the lid, and carefully remove the medium.
* Let the jars cool down naturally before storing them in the fridge.

Myco-Tetris

Myco-Tetris, a project by Alessandro Volpato, is an interactive initiative involving the public in manufacturing fungal composites, aiming to stimulate biotechnology research and encourage sustainable design. By engaging in activities like playing, building, and learning about fungi, visitors contribute to co-design efforts and applied research in fungal biotechnology.

As the course "Growing Microorganisms for Bioart Projects SoSe24," we are continuing with the Myco-Tetris project, and this document serves as our day-by-day documentation. The actual work spans four meetings, capturing our progress and insights throughout the process.

Day 0 Prepare Agar Medium Petri Dishes

The preparation of agar medium Petri dishes was already completed in advance, allowing the course participants to skip this step. For reference to the original experiment, please see Prepare Agar Medium Petri Dishes

Day 1 Prepare agar medium flat jars

Objective: Prepare a versatile nutritional medium for mushroom cultivation.

Materials: Flat jar, wadding, agar-agar, malt extract powder, marker, distilled water, pressure cooker, precision scale (0,1 g), aluminum foil.

Step 1: Calculate Ingredient Ratios

Component Quantity Custom Quantity

  • Drain any excess liquid.
  • Combine the gypsum with the soaked rice grains, ensuring thorough mixing
  • Transfer the mixture into a heat-resistant glass jar.
  • Create a ventilation hole in the lid and insert cotton wadding for mushroom air exchange.
  • Seal the jars and cover the lid with aluminum foil.

Step 3: Sterilize In Pressure Cooker

  • Sterilize in the pressure cooker for 1 hour (Avoid airtight containers, as they may burst!)
  • Remove the lid from the cooker and let the jars cool down (Adding mycelium now could cause it to cook).
  • While cooling, sterilize surfaces, materials, tools, and hands with disinfectants or alcohol.

Step 4: Add Mycelium

  • Cut a large piece of agar-mycelium from the PD and place it onto the surface of the grain (Select a piece from the outer part of the mycelium where young and fast-spreading hyphae are present). (Do not worry about transferring some agar as well; no harm will occur.)
  • Seal the jar with its lid.

Step 5: Incubate

  • Incubate the jar at room temperature in dark conditions.
  • After 3-6 days, consider gently mixing the grains to facilitate faster growth, either by using sterilized spoons to stir within the jar or by gently shaking to break up clumps.
