Yоu set up three sepаrаte test tubes cоntаining equal amоunts of glucose along with appropriate media setup and conditions to support growth as follows: aerobic respiration, anaerobic respiration, and fermentation. You inoculate each with E. coli, which is capable of growth using any of these approaches under the appropriate conditions. You proceed to measure the optical density of each culture using a spectrophotometer by way of measuring their growth. Which culture should reach the highest optical density, i.e., the greatest turbidity, representing the most cells produced? Copyright 2025 by Dr. Jonathan A. Miller. All rights reserved.
