Conversion efficiency during microbial limitation. (A). Measurement of CO2 production as an indication of biofilm development rate, and the peak activity on three cellulosic substrates with equal size, but different mass. (B). Comparison of average conversion efficiency during the initial microbial limitation zone. A doubling in rates of gas production is understood as a doubling of sessile population size, and peak rates are strongly influenced by availability of attachment surface area. The combination of these factors reveals the average conversion efficiency during microbial limitation and it becomes an indicator of biofilm colonization potential (higher is better). Error bars show standard deviation.
