I am wondering whether those are d-lactate forming bacteria
I thought I had a list of D lactate formers somewhere but couldn't find it. From memory, B. lactis isn't, at least some strains of L.rhamnosus aren't, but don't know if this applies to all. I think some strains of L. acidophilus may be both D and L lactate forming but don't remember which. Have no idea about O. formigenes.
On a slightly different issue, I have run into trouble getting the Oxalobact probiotic from the Indian Online Pharmacy. They say they can't get the stock, nor any of the other brands with the same content, though didn't bother to tell me this until after I had sent the money - and only when I asked where the good were!
First time around things went very smoothly and dealing with them was easy. This time around the experience has been absolutely hopeless, getting any information out of them has been like pulling teeth!
The process of getting my money back seemed to be so fraught that in the end I asked for some alternative products though I still can't get them to tell me if they have actually sent them.
My original order was in May - the whole thing has been so horrible I doubt that I would ever try to deal with them again.
