They would die being sealed in their package and be useless. Also companies can't prove they are not using anaerobic species just by saying so since nobody would check.....
Can probiotics in fish food (ex: hikari cichlid gold) live without air?

They use a cold re-extrusion process to ensure that the bacteria remains viable, and they test each batch post extrusion. They are also the only company that I am aware of that utilizes this technique.
New Life Spectrum Probiotix — New Life Spectrum®: Fish Food
New Life Spectrum® doesn’t do marketing gimmicks. If we release it, it has to work. We’ve created a real probiotic food with a biologically effective concentration of probiotic bacteria(at least 3 million viable cultures per gram!). The probiotics aren’t just coated on the surface.

I wrote a sticky on this subject several yrs ago, you might be interested in reading that as well.
The Use of Probiotics in Aquaculture
The use of probiotics in aquaculture has been around for decades but has gained some new popularity in the past few years due to a few fish food manufacturers incorporating some of these bacteria in their food. While numerous publications & studies about the use of probiotics and/or...www.monsterfishkeepers.com
Companies that have their reputation and a lot of money on the line aren't going to NOT test their foods bacteria count, at post production levels. You want to prove otherwise, send a sealed retail container to a lab and post the lab results.
They live in guts without air so i assume they can live in containers.
This just reminded me of something I was wondering. Long story short, I have two opened 2mm NLS probiotix bc of a error in an order. I assume I shouldn't freeze a container of Probiotix to extend shelf life as it might kill the bacteria?
I know it's been discussed that freezing NLS is unnecessary if you're gonna use it within a year of opening but you can extend the life by freezing it. I think RD said he did an experiment and his frozen NLS was good for at least three years in the freezer.
I'm not sure if I can go through these containers within a year of opening as I feed mostly 1mm and only a few of my fish are big enough for 2mm to be appropriate for them.

I suspect that freezing that formula would harm/kill the bacteria. You would be better off storing in a cool, dry, dark location until feeding, even if it is past the 1 year mark.
