(10:00 am) Started looking at the colonies and taking photos until the camera died after 11. The other 16 will have to wait until later.
(13:00 pm) Finished photographing all colony plates as the camera was charged. The next stage to make new plates which have polystyrene as the sole carbon source in an attempt to isolate the microbes from our normal agar colonies that use polystyrene, it's a way of purifying our colonies. This may take a while for the colonies to grow so our computer scientist will run simulations of what the degradation would look like over a period of time that exceeds the running time of our project. The new plates consist of a very small amount of agar so that when this carbon source runs out they switch to the expanded polystyrene which we have melted with acetone to produce a molten polystyrene suspended in the acetone. To maintain the liquid state of the polystyrene we will use the orbital shaker provided by Heathrow scientific for which the team is very grateful. The polystyrene sludge is then placed as a layer in the glass petri dish with a thin layer of agar on and around the polystyrene to start the growth of the bacteria, but will quickly be used up on top of the polystyrene, and will support and outside colonies that spread past the edge of the polystyrene.
(14:30 pm) If this doesn't work for some reason, we are testing out the dissolving power of other solvents on polystyrene. 50%, 66% and 75% Acetone (diluted with still water) had no effect on the polystyrene. Pure methanol is the next target, and also had no effect on the polystyrene.
