Bacteria eating citric acid
I found mold inside bottle with dissolved citric acid, bottle were closed. It don't need air to grow.
Same mold were found in beaker with citric acid and copper complex on air.
You know what it is? Is it visible under microscope?

Aqueous citric acid is an excellent bacteria nutrient. Why don't you have a look yourself?

I once cut open a chilli pepper that i knew was so hot that it bordered on being classified as a chemical weapon, and inside was a small caterpillar
munching away happily.

Mold isn't exactly a bacterium, but mold can grow in a solution containing solely sodium carbonate for a while, so it's not too big of a deal.
Nonetheless, popping it under a microscope and staining it with Tincture of iodine could be interesting. I think Iodine stains molds, it stains yeast
at least.

I don't find that particularly surprising aga, capsaicin is not particularly toxic and only mammals have the TRPV1 receptor which responds to
capsaicin.
I do find it surprising that bacteria could live on pure citirc acid not only because of the pH but because citric acid doesn't contain phosphorous or
nitrogen both of which are required for DNA and proteins.

You forget, yeast can 'live' on pure sugar, for a while. Live just means 'not die' in this case, not 'sustain themselves indefinitely'. Eventually
they'd need phosphorus, nitrogen, maybe more for some enzymes. But not for a little while.

What !
They evolved to specifically hurt us and create Chilli con Carne !
Those plants can be quite nasty.

Actually they did haha, they don't like to be eaten by mammals because they usually chew the seeds to a pulp. Birds are a way nicer mean of
transportation, no jaws chewing your precious babies and a nice pile of personal manure miles and miles away for them to grow in.

That's interesting. I'd like to have a sample of a yeast or bacterium which had a lot of different digestion pathways, though that isn't common, is
it.

Shit, never try to speak English after more than a couple of beers... Sounds strange to use "plural" for a singular way of transportation.

Oh, microbes, especially fungi, are incredibly versatile and opportunistic. I've seen white, fluffy colonies floating on cacodylate buffer, for
frick's sake.
Algae (in this case, cyanobacteria) can be great, too. For example, 18 MO water for HPLC that clogs inlet frits...algae. Growing only on CO2 and
whatever else can diffuse into the vessel. I had to keep the stuff at 80°C on a hot-plate to keep this from happening.
No matter how big and bad you are, the microbes always win in the end. Humanity the apex of evolution? My ass.
