Chapter 2, Problem 2.35P
Interpretation Introduction

(a)

Interpretation:

If a low or high value of specific growth rate is desired when bacteria are used in the production of a commodity chemical should be explained.

Concept introduction:

When an initial growth of bacteria cell is introduced to a nutritional medium. The cells exhibit balanced growth. This means that for a given period the population of cells double. The time required to double the population is called the doubling time. However, the doubling time depends on the factors like type of bacteria, temperature, nutritional medium etc.

Following equation is the modelled equation for this growth,

dCdt=μCwhere,C=Concentrationofbacteriaintheculture,μ=Specificgrowthrate,t=time

Interpretation Introduction

(b)

Interpretation:

Using the given expression, a graph should be plotted with a straight line and value of growth rate and initial concentration should be determined.

Concept introduction:

When an initial growth of bacteria cell is introduced to a nutritional medium. The cells exhibit balanced growth. This means that for a given period of time the population of cells double. The time required to double the population is called the doubling time. However, the doubling time depends on the factors like type of bacteria, temperature, nutritional medium etc.

Following equation is the modelled equation for this growth,

dCdt=μCwhere,C=Concentrationofbacteriaintheculture,μ=Specificgrowthrate,t=time

Interpretation Introduction

(c)

Interpretation:

The specific growth rate using given data should be calculated.

Following equation is the modelled equation for this growth,

dCdt=μCwhere,C=Concentrationofbacteriaintheculture,μ=Specificgrowthrate,t=time

Interpretation Introduction

(d)

Interpretation:

An expression for the doubling time of a bacterial growth should be derived and the doubling time should be calculated.

Q2] The reaction AR + S is irreversible and first order. It is conducted in a PFR with 50 tubes, each with 0.5 in diameter and 1.0 m of height. 200 kg/h of reactant A (MW-80 g/gmol) with 30% inert is introduced at a pressure of 50 atm at 500°C. The output conversion is 80%. Calculate the average residence time.
