Mold growing on blow-off tube water -- batch ruined?
It's not at all ruined. The airlock is working exactly as intended. Unless there is a growth of mold all the way up the blow-off tube and into the fermentor, you're fine.
It's not so much that the ...

Possible contamination or mold?
Unless whatever you're bottling is genuinely, horrifyingly undrinkable- I'd never pour anything out before bottling. At any rate- it won't hurt you.
It's really difficult to tell on a picture through ...

Best way to clean moldy fermentation bucket
StarSan is a sanitizer, not a cleaner. I'd use Craftmeister alkaline cleaner. Amazing stuff and makes PBW look weak. Or just buy a new bucket.

Mold or fermentation not touching the edge of the carboy
Your Mold or fermentation is not touching the edge of the carboy due I would imagine to the dished bottom or side form of the carboy, which is forming the interesting looking krausen. Looks like yeast ...

Dark liquid floating in secondary fermentor
I'm reasonably certain its beer ;) Even a pale ale looks dark in a carboy when it clears.
Your yeast is settling to the bottom and in that process the beer at the top is clearing. But this beer is ...

Primary Fermentation - Mold or Yeast by product?
I was once told that a general rule is any white infection is salvageable as a sour if you so choose, any green must be dumped. Personally I hate sours and will dump all infections, and that's ...

Mold on Cider is it unsafe after boil
Toxins produced by fungi (mycotoxins) will often not be broken down by heat.
If you have had a funky mould growing on your cider before fermentation, then I would probably ditch the whole lot and ...

does my ginger bug have mold?
Yeast is a mould (fungus), so you want your ginger bug to have mould. If it has brightly coloured mould - black, red, yellow, discard it. Generally yeast will stay in suspension for a while, before ...

Cotton looking mold on my sour
IMHO mould growth is not often fatal to brewing but you should remove the fungal mycelium, preferably before it spores, with (e.g.) a spoon and continue fermentation. Seems like a lot of air/head ...

Mold or Floating Yeast?
OP's pic sure looks like normal yeast activity.
Any bubbly, fuzzy looking stuff or rafts with "tendrils" stretching outward (like in the pic below) can be a cause for concern. OP just has ...

Dilemma whether it is MOLD on kombucha with green section
I’ve been brewing Kombucha for 2 years now and have never had anything like that on my Scoby. I’d dump it and not take any chances.

Mold or fermentation not touching the edge of the carboy
Looks like a standard beginning fermentation. I wouldn't worry yet. Give it time, it will likely turn out alright.

Best way to clean moldy fermentation bucket
Depending on what bucket you use, it might just be easier to buy a new one. :)
Otherwise, get an unscented soap and wash properly. Rinse, wash again, just to make sure. Rinse well. And verify that ...

Suspected mold in elderflower country champagne
Wine vinegar? If the acetobacter was still alive it could be eating up the new alcohol, making more acid and maybe the floculant stuff too. Idk, just a thought.
Also, may not have caught a wild yeast,...
