• Question: hello there i would like to ask you if you have ever been able to grow bacteria in an air compressed space or an area where there is hardly any oxygen (outer space) if so how long would it take to be able to make enough bacteria for some blue cheese?

      I don’t really grow bacteria – or at least don’t mean to. I’m pretty sure there are some in the compressed area that its my fridge though.

      Bacteria can grow in some pretty extreme places. There are lots of species that grow best without any oxygen in their environment, like the ones in your gut which help you digest vegetables.

      Others live deep in the ocean, and earth, where the pressure is so high it would crush a submarine. Some of these deep ocean bacteria take such a long time to grow it would take over a thousand years to make cheese.

      This might be quite difficult because just like you and me, bacteria need oxygen to live. Although like Jon said there are many “extremophiles” which can survive in surprising environments.
      But I don’t think I’m going to try an experiment with this because I would not be too happy with a load of bacteria making smelly cheese around me.

      I grow bacteria to make protein. Basically, I give them some DNA which tells them to make loads of the protein I want. I want them to grow well make lots of protein for me and the bacteria I use (E. coli) need air so I try and make sure they get as much as possible. So I’ve never tried it in non-airy conditions.
      I would like to though. I like that there are some pretty ace bacteria out there that can live with no oxygen, like Tom and Jon said. And cheese in space sounds like an excellent idea. And movie.
      Apparently, bacteria for blue cheese survive in really low oxygen environments, which makes them ideal for growing in the middle of cheese. So if you can get a bacteria that makes a mould and can live with no oxygen, I think it wouldn’t take any longer than it normally does to make blue cheese.
