Yes, but only if they are single strain cultures, or ones that are undefined, multi-species culture. So you couldn't simply propogate MM4000 series from Danisco, for example, but you could propagate Abiasa's meso B.
If they are multiple-strain cultures and you propagate them forward, the concentration of the respective blends will change if you just use broth or 11% (or less) skim milk. Also, you need to propagate correctly. Meaning not only watching your aseptic technique, but also acidity and temp. High acid will damage bacteria, and that acid level is different for each strain. I have posted about this before in one of the threads I linked to in your other thread.
If you want to duplicate a culture that's multi-strain and not stable, you will need to first isolate the strains, reculture each individually, and then combine starters into your milk if using bulk starter or lyophize them and blend. Of course, there are legal considerations when doing this commercially, such as patent infringement, etc.
The difference between abiasa's meso B and something like MM4000 is that abiasa's B is cultures with all the strains in the tank already, and it is a culture that has achieved relative balance over time, sort of like sourdough blends achieve balance. So you can keep propagating forward. Mixed strain cultures and blended after the fact according to proprietary formulas, and lyophilized, so of course if you want to recreate that, you have to repeat what the manufacturer did.
The rest of the threads I linked have lots more answers
edit: if you don't care abotu exactness and consistency, you can use the skim milk method and propagate anything forward. Also, a first-maybe-second gen propagation even from specific strain DVI mixes should be OK.
