Hey all,I know that it could solve maze, remember the food location, and even predict periodicity of environment. Are there any more (surprising) discoveries on the intelligent ability?Thanks,GusContinue

"That's probably  oat meal agar - 10%  oats in 1% agar if I remember rightly.  More accessible might be to use cooked oats rolled out and sliced into squares. "

What is this food for slime mold

Dear All,Anyone knows what is this perfectly "round" shape food for the slime mold in the following two pictures (screen shot from youtube)? I am currently using oats to feed the mold, but my experiment somehow requires a standard food source in exactly the same weight, shape.Thank you very much!Gus…See More

which agar can grow Physarum without oat

Hi,I am new to Physarum Polycephalum. I see in most agar plates, we put oats. I was wondering if any kind of agar plate can grow Live Physarum polycephalum without oats? Especially some prepared ones I can purchase online.I prefer not using oats because I am interested in its shape in a free-growing condition. Putting oats will influence the shape since the slime mold pursues the nutrient. If any preferred nutrient is mixed with the agar evenly, I guess the problem is solved.Thanks a lot!Gus See More

It depends what you want to test. Its growth behaviour changes depending on the substrate it is growing on, i.e. it tends to swarm as a mass cell on nutrient agar and branch out in seek mode on non-nutrient agar (I use 2% agar powder or cooking agar). Slime mould will grow on non-nutrient agar but will be more actively looking for food. See https://youtu.be/5tYKYpQzu6E at end when food is taking away its growth becomes more frenetic.

Nutrient rich agar also gets contaminated more quickly.

If you want to try an agar which contains nutrient but isn't visible or lumpy, you could try a mix of yeast extract (Marmite) and dextrose (energy tablets). I have used this as feed, which it loves, but haven't tried mixing it with agar - but I can't see why it wouldn't work.

Try 1 teaspoon of marmite + a third of a dextrose tablet per 100ml of water (recipe comes from Audrey Dussutour via Natalie Andrews). Though I suspect the agar will contaminate quite quickly.

Let me/us (the collective) know how you get on.

I have fed it flour before too, you could try mixing that with agar, it should disperse evenly.

Good luck!

Heather
