If a culture of Haemophilus contains 105 cells/ml at 4:00 a.m. and 101

1.	If a culture of Haemophilus contains 105 cells/ml at 4:00 a.m. and 1011 cells/ml at 4:00 p.m., calculate its specific growth rate and doubling time. Which growth phase in this bacterial culture will show maximum specific growth rate?
Answer» Specific growth rate- 1.1515 hr^-1 Doubling time- 0.693/1.1515=0.6 hours=36 minutes Exponential phase
