B.3.3. TIMELINE

B.3.3.
Transparent pot with a draining system

Run through: 14. 08 – present;
Total batch weight: 2.72kg;
Bokashi fermentation proportions: approximately 1.4:10 → 340g Bokashi + 2.38kg HOW (contains lasagne and meat remains);
HOW was minced in a blender; anaerobic fermentation.

Experiment 16. 09. 2019: colouring attempt 03


⌕ Can the HOW material be coloured?

⌕ Which pigments can be used without being decomposed by the fungi enzymes during mycelium forming?

This experiment focuses on testing if different colour dyes preserve during the mycelium forming stage, and if colour dye hinders mycelium forming when the HOW substrate is present.

15 medium Petri dishes were prepared; 10 dishes containing HOW substrates from all batches laying around at the time, and 5 control dishes. The red and blue silk dyes were poured on top of the dishes after the mycelium spawn and the HOW were mixed. As yellow dye, turmeric powder was mixed homogeneously in the mycelium control dishes.



Day 01. Red control & all samples
Day 01. Blue & yellow controls
Day 04. Blue & yellow controls
Day 09. Red control & all samples
Day 16 of the experiment. Examples (left to right): samples B.3.1.2B, B.3.2.2A, B.3.3.1B & Yellow B
The red silk dye preserved during mycelium forming in most situations.
The blue silk dye was decomposed during mycelium forming, the colour dissapeared until the end of the process.
Of the 3 yellow dye control dishes, the C sample didn't grow.

This experiment concluded that colouring the HOW material is possible but the exact conditions in which this must happen are yet to be researched.
