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.
  Yes, it can ferment lactose. Mannitol Salt Agar is used to identify S.aureus. When it ferments D-mannitol, it produces an acid which turns the agar yellow from red. S.ep â¦ idermidis will grow, but the agar remains red.5 people found this useful.1  Preventing Food Transmission of Staphylococcus Aureus Staphylococcus aureus, commonly known as staph, is the bacteria known to cause staph infections and food poisoning. 2  The Staphylococcus aureus bacteria itself does not cause fâ¦. people found this useful. 1  Preventing Food Transmission of Staphylococcus Aureus Staphylococcus aureus, commonly known as staph, is the bacteria known to cause staph infections and food poisoning. 2  The Staphylococcus aureus bacteria itself does not cause fâ¦.
