From the slope of the line, we can calculate the specific growth rate k of the culture, which is the most encompassing parameter of how fast a particular bacterium growths in a particular media. For example, if a culture contains 10^3 cells at time t1 and 10^8 cells at t2 6 hours later, the specific growth rate k is. Specific Growth rate calculation. SGR = (lnW f - lnW i x100) / t: If the Food Conversion Rate is known, the SGR can also be calculated by dividing the Percentage body weight fed per day by the food conversion rate. This calculation can be turned round to predict growth if the SGR is known A. The formula to calculate future population given current population and a growth rate is: Where: Pop Present = Present Population i = Growth Rate n = Number of Periods. To calculate your future balance in the above example the formula would be: Future Value = $100 * (1.05) 5 = $128 How to Calculate Growth Rate - Calculating Basic Growth Rates Obtain data that shows a change in a quantity over time. Apply the growth rate formula. Express your decimal answer as a percentage. Rationale. RGR is a concept relevant in cases where the increase in a state variable over time is proportional to the value of that state variable at the beginning of a time period. In terms of differential equations, if is the current size, and its growth rate, then relative growth rate is . If the relative growth rate is constant, According to some textbooks, the specific growth rate is the highest during Log phase. However in my calculation, the specific growth rate is the highest just after lag phase. A biomass-OD curve was used to determine biomass during the growth phase.
property and Mu net which is specific growth rate which is given as 1 /X DX DT. So this Menten kinetics and the equation for the gross specific growth rate Mu. 21 Jul 2008 Equation 3.1 can be used to calculate the generation time as well as the specific growth rate using data generated from a growth curve such as
From equation given above, it can be seen that, if all of the cells can be The effect of substrate concentration on the specific growth rate is shown in the figure A study was conducted in in vitro condition to determine the specific growth rate, sugar consumption and generation time of four diazotrophic bacterial species, 10 Feb 2017 The equation developed by Monod [1], which describes a hyperbolic dependence of the specific growth rate on the external concentration of 17 Nov 2016 μnet is net specific growth rate (h-1). μ: specific (cell) growth rate Ludeking- Piret equation – If α=0, the product is non growth associated, 15 Apr 2007 E is equal to the formula, which was introduced by Schwartz ( 14) to estimate the growth rate of tumors. To estimate DT of a tumor, its volume 8 Jul 2014 Lines and equations represent the best fit by linear regression. There was a positive correlation between growth rates at harvest and subsequent function of the specific growth rate (dilution rate) in chemostatic cultures limited Equation 1 was used to compute growth on acetate assuming that the rate of

8 Jul 2014 Lines and equations represent the best fit by linear regression. There was a positive correlation between growth rates at harvest and subsequent function of the specific growth rate (dilution rate) in chemostatic cultures limited Equation 1 was used to compute growth on acetate assuming that the rate of The Monod equation for the specific growth rate, Eq. (12.91) , is analogous mathematically to the Michaelis–Menten expression for enzyme kinetics. In principle, therefore, the techniques described in Section 12.4 for determining v max and K m for enzyme reaction can be applied for evaluation of μ max and K S . Specific Growth Rate (Monod) Equation & Calculator. Specific growth rate (Monod) equation calculator - formula & step by step calculation to measure the dependence of the growth rate on the substrate concentration of bacteria or aerobic metabolism. μ = μ max x (S/(K s x S)). Maximum specific growth rate μ max in time -1, 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.
