Hydrogen 20-28 polyhomeotic homolog 2 Homo sapiens 70-73 16201664-7 2005 A method is presented to calculate PH2 values along the flow direction in a PRB, and thus the maximum PH2 value that can possibly develop, assuming no bacterial utilization of the produced hydrogen. Hydrogen 189-197 polyhomeotic homolog 2 Homo sapiens 35-38
