| show | skin normal flora makes catalase
🗑
|
||||
| differentiate between aerobic and anaerobic respiration | show 🗑
|
||||
| show | Fermentation- organic compound is final electron acceptor
Anaerobic respiration- inorganic compounds other than O2 are final electron acceptor
🗑
|
||||
| Would nitrate reduction occur more often in the presence or absence of O2? | show 🗑
|
||||
| In nitrate reduction test, what does the presence of gas indicate? | show 🗑
|
||||
| show | nitrate reduction is harmful because plants need nitrates to survive. If nitrates are reduced to NO or N2, there is less available for the plants.
🗑
|
||||
| show | The nitrates were reduced to nitrites then nitrous oxide and finally to nitrogen gas
🗑
|

|
||||
| show | To classify bacteria as aerobic or anaerobic.
🗑
|
||||
| show | P. aeruginosa and B. subtilis
🗑

| show | anaerobes
🗑
|
||||
| The oxidase and catalase test test for what kind of organisms? | show 🗑
|
||||
| show | If there is gas, the nitrate was reduced to nitrogen gas.
🗑
|
||||
| show | nitrate-->nitrite-->nitrous oxide-->nitrogen gas
🗑
|
||||
| show | 3,000,000
🗑
