Tempeh - Rhizopus oligosporus seen through the microscope

[@huideli]

I love the video. It clears off my doubt on why the tempeh turns from white to grey and then black. Pay gratitude to you.

Thanks ! Yes, when it turns black it's less appetizing but it shouldn't be toxic. It's the same fungus.

Hey, just wondering what substrate did you grow the fungus on? I'm assuming agar added with something

[@BernardJenni]

Potato dextrose agar or malt extract agar
