Question

Refer to the below graph, determine the specific growth rate µ and the doubling time.

(a) (0.118 hours, 5.9 hours)

(b) (0.119 hours, 5.9 hours)

(c) (0.151 hours, 5.9 hours)

(d) (0.119 hours, 5.9 hours)

The question was asked in an online quiz.

My enquiry is from Graph Paper with Logarithmic Coordinates in division Presentation and Analysis of Data of Bioprocess Engineering

Answer 1

Correct option is (a) (0.118 hours, 5.9 hours)

To explain: The regression results show that μ = 0.118 hr^-1. The doubling time,

td = ln(2)/μ

= 0.693/0.118

= 5.9 hrs.
