where, rsu is the substrate utilization rate (in mg m −3 d −1 ), k is the maximum specific substrate utilization rate (in g of substrate g −1 of microorganisms d −1 ), So is the concentration of the limiting substrate for growth (in g m −3 ), X is the microorganism concentration (in g m −3 ), The Maximum Rate of Soluble Substrate Utilization coefficient is referred to by the symbol k. This coefficient is used for designing a complete-mix activated-sludge system and has to do with the biomass growth process. A breakdown of 10% saturated, 10% polyunsaturated, and 10% monounsaturated fat is recommended to ensure an adequate intake of all essential fatty acids. Substrate utilization in CF is an area of growing interest and research. Our substrate disappearance rate can be described as: U = 1/X dS/dt where . U = specific substrate utilization rate S = substrate concentration. FURTHERMORE. Substrate concentration and cell growth are obviously interrelated. As cells grow, they use the substrate so it disappears. We can write the expression: dX/st = -Y dS/dt The system of equations can be simplified, by using the relationship RB=Y*RA (RB is the biomass growth rate and RA is the substrate A utilization rate).

The biomass yield for 14 g/l substrate was 70.7%. The maximum specific growth rate (µm) of the obtained and fitted data is close to the calculated ìm of the 21 Jul 2008 between the specific growth rate and the substrate concen- tration. There are two of substrate utilization given that growth is related to sub-. Objective: To determine the specific substrate utilization rate of a given bacterial culture. Introduction: When microbial cells are inoculated into a fresh culture 31 May 2016 maximum substrate utilization rate, Kmax, of 0.0089 mg CH4/mg include influent flow rate, reactor volume, void fraction, specific surface area,. The rate of substrate utilization is related to the specific growth rate as follows: r su = −μX/Y. where: X is the total biomass (since the specific growth rate, μ is normalized to the total biomass) Y is the yield coefficient; r su is negative by convention.
