Bacteriologists: Does M9 Cause Gas in Ostomy Pouches?

I understand that M9 works on output bacteria to manage odor. What I want to know is if, in the process of doing that, are gasses and/or fermentation caused in the pouch?

Why I wonder: I have always had major issues with gas, apparently unrelated to diet, and found no products or filters worked to address it. Recently, due to side effects from Chemo, I began taking very low dose Oxycodone. Huzzah! no more blown up pouch, not even during the night which has been a major problem. Two days ago, I decided to try M9 for odor control. Shortly after the first application, I am back to a drum-tight pouch. I emptied, rinsed, and used my regular Brava lubricating deodorant. No gas. Tried M9 again: GAS. 

Anyone know the science or have a different experience? 

I was also having a lot of problems with gas blowing up my bag like the Hindenberg! No diet changes seemed to help. My GI turned me on to a product called Atrantil. I ordered it and I take 2 of them before meals and that has helped a lot! No more fears of the Hindenberg blowing up!

Thank you! I'll speak to my care team about using Atrantil. So glad you're more grounded😁

Shamrock, I avoid antibacterial soaps outside of wound care and surgery prep. It seems that, so far, there's no real proof of effectiveness with such OTC products and no safety studies for long term use. The Brava deodorant handles the odor okay. My issue is with the sudden recurrence of pouch bloating since the M9 use.
