A glass flask is rinsed and autoclaved after use. It was then filled with sterile media in a sterile environment and covered. A few days, microbial growth appears in the flask. Assume the media and sterile environment is guaranteed to be sterile. What most likely caused the growth in the flask?
a. The flask has to be rinsed with bleach before autoclaving
b. A portion of the flask was not exposed to the steam
c. Autoclaves only sanitize equipment, so you cannot expect the flask to be sterile
d. Autoclaving inhibits growth, but does not kill microbes

It can ferment glucose, meaning it is positive for fermentation of glucose test. It can also reduce nitrate. What is it? b. This bacterium is a gram-positive rod. It is negative for the catalase reaction, but does produce gas from glucose. What is it?arrow_forwardAnswer the question briefly and concisely. The Mannitol salt agar (MSA) only allows the growth of halophiles (salt-loving microbes);nonhalophiles will not grow. Among the halophiles, mannitol fermenters will produce acid that turnsthe pH indicator yellow; mannitol nonfermenters leave the medium red. Onto MSA you inoculate ahalophilic mannitol fermenter and a halophilic mannitol nonfermenter. In this case, the medium isacting as (a) __________ medium(s).A. SelectiveB. DifferentialC. Selective and differentialD. Enrichedarrow_forward
