What is the most effective way to kill microbes ? |
HEAT (High temp) |
|
|
Moist Heat |
(Heat+Water) MORE effective than dry heat. Kills microbes faster and at a lower temp EX. Autoclave, pasteurization, tyndallization |
|
|
Thermal Death Time |
Shortest time period required to kill all microbes in a sample when exposed to a specific temp under standard conditions. |
|
In lab 13 we used Bacillus thuringiensis. What was the outcome? |
It was able to survive the hot temp because Bacillus is a spore. |
|
In lab 13 we used S. aureus . What was the outcome? |
the TDT was at 5 min bc it was too hot. Therefore was not able to survive the temp |
|
|
Give 3 factors that would affect the TDT of a bacteria. |
Spore formation Amount of heat quantity of microbes |
