A common concern for beer brewers making sour beers is contamination from Acetobacter. This organism converts ethanol to acetic acid and gives the finished product an undesirable vinegar flavor. Which of the following media would serve as a good enrichment medium to detect the presence of Acetobacter in a brewery environment?

a. Carbon dioxide, yeast extract, trace elements
b. Cellulose, phosphate buffer, magnesium sulfate, calcium chloride, trace elements
c. Ethanol, ammonium chloride, phosphate buffer, magnesium sulfate, calcium chloride, trace elements
d. Glucose, ammonium chloride, phosphate buffer, magnesium sulfate, calcium chloride, trace elements

Option C.

Explanation:

Acetobacter is an acetic acid bacteria that convert ethanol to acetic acid in the presence of oxygen. This bacteria oxidize lactate and acetate into carbon dioxide and water. Acetic acid bacteria are found in media that have high concentration of carbohydrates like fruits and ethanol. Acetobacters are found in fermented foods. Ethanol, ammonium chloride, magnesium sulfate, calcium chloride, phosphate buffer and trace elements are good enrichment media for acetobacters growth because of high concentration of sugar.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

thats not even an aswer choice
