Earlier this year, I’ve decided to donate all equipment to the Creative Technology Hub at the Moholy-Nagy Design University (MOME) in Budapest, Hungary.

  • 100ml liquid culture as control in a 500ml Erlenmayer flask, composed of:
    • Nutrient Broth: 8g/1000ml -> 0.8g
    • NaCl: 30g/1000ml -> 3g
    • Glycerol: 10g/1000ml -> 1g
    • CaCO3: 5g/1000ml -> 0.5g
  • 100ml of the same liquid culture, placed on a magnetic stirrer
  • 100ml of the same liquid culture, but without CaCO3
  • 100ml of the same liquid culture, but without  Glycerol

and left these overnight on the table at room temperature (well, lab temperature, around 20C)

today I’ve found that:

  • the control was producing light when shaken
  • the culture without the CaCO3 was producing light when shaken
  • the culture without Glycerol was producing light when shaken
  • the culture on the magnetic stirrer is constantly producing light, with the light visible around the vortex of stirring

thus it seems that a minimalist nutrient liquid without CaCO3 and/or Glycerol might already be sufficient

It seems that the ‘botched’ liquid culture from two days ago came to light today as well. The following images show the result, in a pitch dark room with some reflection off the wall (well, a tiled bathroom), at 10sec, f/4, ISO 800:

In short, I prepared two 100ml cultures (one PP BH and one PP LumA)  in a 500ml Erlenmayer flask each, with the following composition each:

  • Nutrient Broth: 8g/1000ml -> 0.8g
  • NaCl: 30g/1000ml -> 3g
  • Glycerol: 10g/1000ml -> 1g
  • CaCO3: 5g/1000ml -> 0.5g

The ‘botched’ bottle from two days ago had the same ingredients, but in cca. 180ml of water. The result is well visible in a dimly lit room. I personally can’t tell the difference between the PP HB and the PP LumA variants.

The bacteria light up only when you oxygenize the culture, for example, you shake / stir the liquid culture. after that, it stays visibly bright for about 7 minutes. See the following image sequence, taken in a loosely lit room in 1 minute increments, at 3s, f/4, ISO 800:

I grew out two of each on agar plates, with the following ingredients for 4 plates, 80ml of Agar total:

  • Nutrient Broth: 8g/1000ml -> 0.64g
  • NaCl: 30g/1000ml -> 2.4g
  • Glycerol: 10g/1000ml -> 0.8g
  • CaCO3: 5g/1000ml -> 0.4g
  • Agar: 15g/1000ml -> 1.2g

I also tried to create a liquid culture, where I botched the ratios and ended up with twice the liquid for the amount of ingredients.

The plates lit up overnight, the liquid culture didn’t. They are quite bright when compared to Vibrio Fischeri. Below are images with various ambient light and photo settings used to take them. other than cropping the first two images, no modification has been made. The two plates on the right left are the PP HB plates, the right ones are the PP LumA plates.
