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.
Lactose intolerance is a common problem. It happens when your body does not have enough lactase, which is an enzyme produced in the small intestine. Lactase is necessary to digest lactoseâthe natural sugar found in milk and other dairy products.In the intestines, undigested lactose leads to the buildup of gas.Within 30 minutes to 2 hours after eating dairy products containing lactose, people with lactose intolerance start to develop stomach cramps and diarrhea.actase is necessary to digest lactoseâthe natural sugar found in milk and other dairy products.
