Two plates of v. fischeri brought to lab. They are bioluminescent and glow green in the dark. When we got them they had been growing for a few days on 'BOSS' media (BOSS medium: 1% peptone, 0.3% beef extract, 0.1% glycerol, 3% NaCl, 1.5% agar, pH 7.3)

Equipment

We need to fix our incubator with shaker, or make a new one.

Requirements

  • Easily cleaned + sterilised
  • Either a shaker powerful enough to agitate full beakers, or a magnetic stirrer (which we have already started building). Magnetic stirrer may lyse cells. An idea for a shaker could be a record player.
  • Can be made dark inside
  • Adjustable temp
  • Low power if possible.
  • Temperature mesaurement (simple thermometer would do)
  • Does it need to be sealable?
