How can growth of bacteria inhibited?
by using a bacteriostatic agent or making conditions unfavourable for growth ie. by changing the temperature, oxygen availability, pH, nutrient media on which it is cultured.
At what tenperature is bacteria most active?
It really depends on the bacteria. Some multiply best at room temperature, some at 60 deg celcius. Bacteria has 4 phases in life. The lag, log/exponential, stationary or the death phase. Bacteria multiply best at its log phase. The log phase depends on the bacteria species.
What happens to the growth rate of bacteria when you freeze them?
Freezing bacterial cultures slows the death rate of the bacteria. When bacteria is frozen it goes into a sleep state and does not grow or multiply.
What are the consequences for a loss of ability to sense temperature?
not being able to feel the sensation of getting burned or freezing
How does a freezing microtome work?
Since most biological specimens are too squishy to cut at room temperature, a freezing microtome, also known as a cryostat, freezes the specimen to harden it so it can be sliced without ripping and destroying it.
How does freezing temperature affect mocroorganisms and enzymes?
Freezing temperature make ice of the water in bacteria and completely stop there metabolic activity. Enzymes do not work at freezing temperature as they have no scope for movement in solid ice. So there activity halted.
At what temperature will bacteria lay dormant on food in a freezer?
Food poisoning bacteria go dormant at and below freezing. All bacteria are dormant below -17ºC or 1.5ºF
Will freezing a germ kill it?
the answer is yes. this is because the decreasing temperature would cause most of the bacteria cells to die and eventually the bacteria would die.
What is the effect of freezing on bacteria?
Bacteria like Archaebacteria can survive in extreme temperatures but eubacteria cannot. Since Eubacteria die from the harsh temperature and Archaebacteria cannot reproduce your immune system kills all of the Archaebacteria. That is why freezing in a technical sense stops bacteria from reproducing.
What temperature does bacteria thrive in food tech?
Any temperature less than around 60 °C for most bacteria. However, there are bacteria in food that can survive past 100 °C. Freezing does not significantly kill bacteria, but puts it into a dormant stage, where they can no longer thrive and reproduce.
Freezing food the action of bacteria?
Freezing food slows or stops the action of bacteria
Are bacteria killed by freezing?
Yes, bacteria can survive freezing temperatures. Freezing isn't a sure-fire way to kill the bacterial population in the food. The only thing freezing will do is halt the multiplication of bacteria however thawing will resume the process.
What is sub freezing temperature?
temperature below freezing point of water.
When a solute is added to a solvent the freezing point of the solutions is?
The freezing point is lowered.
When a solute is added to a solvent the freezing point of solutions is?
The freezing point is lowered.
Calculate the freezing point what solutions assuming complete dissociation?
The problem with this question is that you did not provide any solutions, as stated, to calculate the freezing point for.
What temperature is the freezing temperature?
32 degrees Fahrenheit (or 0 degrees celsius) is the point of freezing.
