Do you all think this could be beneficial when using denitrate tubes? Considering it's anaerobic bacteria?
Don't know, I'm guessing no one else reading this does either or they would have posted.
Scott, products such as safe start, bio spira, etc, are not the same type of bacteria as those found in septic products. The former are nitrifying bacteria (that convert ammonia to nitrates) the latter are heterotrophic bacteria (sludge/waste eating bacteria)
Rodger, that's the stuff, although last year a friend (who happens to keep rays) turned me on to a locally made product called Bactri Pond, which I like better as there is no bran medium, just a white powder that dissolves on contact.
And just to be crystal clear, I'm not suggesting that anyone has to use these products to successfully keep rays, or any other species of fish. If you read the sticky on this subject, which Rodger linked to early on, my reason for using these products was due to my own personal situation. For myself personally it's been a success story, for others they may feel that its unwarranted. It's all good, do whatever makes you feel best, I'm not trying to sell anyone anything.
But to state that these products will kill fish, with ZERO proof, while thousands of people world-wide use these same bacteria in aquatic applications, is far more reckless than the people the OP is pointing fingers at. I have been experimenting with these bacteria off & on for over a decade, and I have never once seen a case where a fish die off could be attributed to any of these products, even when overdosed by massive amounts.
Even Seachem Prime can be dangerous under certain conditions, and just like RidX is regulated with a MSDS.

Two hobbyists on a forum of thousands feed NLS to their fish and the fish get bloat, and soon after die. Did the food cause the fish death? Of course not, but over the years I have read this at least a thousand times, with every brand of food on the market being the cause, while millions of others feed the exact same diet with zero issues. To me this is no different than what is being reported here. I'm sorry for anyone that loses a fish, but to blame it on something with zero proof isn't going to further anyones fish keeping experience in this hobby.
