Looking at the test results, it shows 4 groups: Bacteria, Fungi, Protozoa, and Undifferentiated.

So, what is included in this Undifferentiated group?  Does this include bacteria, fungi, and Protozoa that they can not determine what they are?  Does this mean something completely different? 

I ask this question because in the first test, the Undifferentiated is over 50% of Total Biomass - this is more than the Bacteria and Fungi combined.  So, what is this group, and what is the importance?  

Can anyone speak to it?
