Oxidation involves bacteria digesting sugars using oxygen. Fermentation involves bacteria digesting sugars without oxygen. O-F media is used to test bacteria for their ability to oxidize or ferment sugars. Which set of tubes below is oxidative but NOT fermentative?  

A woman was taken to the hospital after a blunt force trauma to the head. Doctor’s reported that her ability to move and respond accurately based on her judgment of speed, motion and distance was impaired. She seemed to lack a sense of location (proximity to other people and objects) and sense of time (what time of day it seemed to be based on environmental cues). What part of her brain was damaged based on these symptoms?

Lab 5 Can we use genetic medicine to treat human health conditions?

Lactose and Dextrose/Glucose Broths contain a carbohydrate (sugar) source for the bacteria. Lactose and dextrose/glucose are the carbohydrates (sugars). Digestion is fermentation. The broth also has phenol red (a pH indicator). Which tube below is negative for gas production AND negative for carbohydrate fermentation?
