VERY cool Deb. What kind of keywords are you searching for to zero in on German cheeses (for example)? Are you searching in the foreign language?
There are really only 7 starter bacteria that we use for ripening plus the Lactic bacteria that are naturally occurring in raw milk. However, there are potentially thousands of "varieties" that may be unique to a given region. The possibilities are endless. It's also not just the bacteria used, but the proportions. The balance can really change the way things ripen and age. For example, when making Emmental or Swiss I use a mix of 50/50 TA61 and LH100. When making Parmesan or Romano I use the same cultures but the mix is 20/80. Why? TA61 is a relatively fast acid producer, but does not completely breakdown lactose. The LH100 takes over and completes the process. (some info provided by the Dairy Connection). I mention this because a given region might have a different balance of natural bacteria as well as unique varieties. When a recipe simply calls for a "Meso" or "Thermo" culture, they are leaving out some really important details.
..and back to the point of this thread. Sometimes these unique biological attributes cannot be copied and deserve to be "registered".
