Bay mud manifests low shear strength, high compressibility and low permeability, making it hazardous to build upon in seismically active regions like the San Francisco Bay Area. Typical bulk density of bay mud is approximately 1.3 grams per cubic centimetre.
Organisms which ferment lactose produce acid end-products which react with the pH indicator neutral red, and produce a pink color. Quadrant 1: Growth on the plate indicates the organism, Enterobacter aerogenes, is not inhibited by bile salts and crystal violet and is a gram-negative bacterium.The pink color of the bacterial growth indicates E. aerogenes is able to ferment lactose.ack to Tutorial. Quadrant 2: Growth on the plate indicates the organism, Escherichia coli, is not inhibited by bile salts and crystal violet and is a gram-negative bacterium. The pink color of the bacterial growth indicates E. coli is able to ferment lactose.
Individual human cells are also facultative anaerobes: They switch to lactic acid fermentation if oxygen is not available. Summary: 1. Aerobic bacteria inhales oxygen to remain alive. 2. Anaerobic bacteria dies in the presence of oxygen, and therefore avoids O2.3. Aerobic respiration produces energy with the help of a complex process in the cells. 4. Anaerobic respiration produces crystals, and causes pain in muscled areas.5.ndividual human cells are also facultative anaerobes: They switch to lactic acid fermentation if oxygen is not available.
