Help ID microrganisms


This lives in acidic conditions, after I fed it with sugar, it died.

Solution with it smells like nail vanish.
Grown in oxygen free environment.

Almost all died, do you know what to feed it with?

What about this ?

A scale would help, but otherwise, nice microscopy. What set up are you using?

Aside, the first looks like a co-fermentation of rods and cocci. The rods may be a Clostridium, perhaps acetylbutylicum (or the like) that are known for acetone-butanol-ethanol (ABE) fermentation. Cocci are probably some facultative anaerobe, say Leuconostoc and friends.

Second and third look like haploid yeast and, maybe, spores (S. cerevisiae) at different magnification, and the 4th like diploid yeast (definitely yeast). They may be the same organism, but in different stages of reproduction/environmental reaction: https://en.wikipedia.org/wiki/Mating_of_yeast

That they die with sucrose is odd, though--they usually don't have a problem with invertase (https://en.wikipedia.org/wiki/Invertase). It's hard to osmotically kill yeast (up to about 30% total sugar, anyway). But, you don't give any other information on your media, so it's anyone's guess as to other nutrient requirements. Perhaps malt, maltose or saccharified starch would yield better results? I'd check the nutrient requirements--they need more than sugar.

In any case, many years ago I observed a wild yeast growing on diluted cane molasses. The smell of acetone would blow your head off when you opened the (5 gal) bucket. No attempt was made, at the time, to see if there was (undoubtedly) a co-fermentation, or with what (chip-based sequencing was still a long ways out).

Don't know condition they living in acidic, fourth or fifth circle with same water not changing. Interesting, adding more sugar every time and it dissolving.
Not that much ol distills. Where does it go by mass.

Uploading pictures of mold that grows on my walls under microscope.
20 - 30 min.
What cause it?

I saw mold ripping of citrate anions from salts.
Wall paint consists of oxides, there's no nutrients for mold, or I wrong?
Can dissolved in moist gases feed it?

Don't know how to get rid of it, tried everything.

Ok, done.

Scrapped bit of mold of the wall, and left it in petri dish for month with a spoon of sugar added.
Check out creacher on 1.45.

Dust, spores and bacterias from air, insects excrements and finally minerals and moisture from wall (Na, K, Ca, SO4, NH4, NO3, H2O)
--> yes molds may grow on walls

Avoid this/get rid of it...
1°) Clean with detergent water, Detol solution, extended Javel water (bleach) and ethanol. And a sponge.
2°) Allow to dry (venting)
3°) Use white bitume paint (usually for outdoors but very effective for bathroom and indoor mold-ed walls), allow to dry and vent

Molds should not show for a long while...
of course:
-use a little venting (forced aspiration/venting, open Windows from time to time)
-allow some space between walls and furnitures and between furnitures... for air, heat (especially on cold walls favourizing condensation) and venting to pass
-and do allow some heating of the room
