xw42n586h4b	Kelly Martin	Effect of Counter-Diffusion, Fluid Dynamics, and Biofilm Morphology on Membrane-Supported Biofilms	2014		.txt	text/plain	365	15	34	MBfR biofilms exhibit unique behavior due to substrate counter-diffusion, where the electron donor and acceptor enter the biofilm from opposing sides. Back-diffusion of inert gases from the bulk liquid and biofilm into the lumen of the membrane can be detrimental to MBfR performance, though the extent of gas back-diffusion and its effect on denitrification is highly interdependent upon substrate concentrations, membrane properties, and biofilm thickness.	cache/xw42n586h4b.txt	txt/xw42n586h4b.txt
