What temperature does bacteria start to die at when frozen?
It actually depends on the kind of bacteria. Based on their temperature requirements (temperatures at which they grow) bacteria are classified as psychrophiles (very low temperatures... even below zero).. mesophiles (above zero to say 20-30 on an average...).. thermophiles (above 50).. extreme thermophiles (very extreme temperatures such as hot springs.. may be in hundreds...).
Do bacteria live in cold weather?
A bacterium grows best between the temperatures of 41°F and 135°F. Also, they require water to grow, so moist places harbor a large amount of bacteria. Dim and dark places also harbor lots of bacteria.in kyler R. 's hair...te he :P
If an organism grows at 20 degrees celsius is it a psychrophile or mesophile?
You cannot differentiate a mesophile from a psychrophile by testing growth at 20 C. Many Arctic/Antarctic bacteria will grow at 20 C. However most true psychrophiles will grow near 0 C but mesophiles will not. Typically most mesophiles will not grow below 15 C. There are no perfect temperature guidelines but testing growth at the extremes of the presumed range can help you decide how to classify a particular bacterium.
What does microorganisms that cause food to spoil need?
Food spoilage microorganisms all need these things, but the specifics may be different* Food * Water * Proper Temperature * pH * OxygenNot all spoilage organisms prefer the same conditions.Thermophiles like it hot. Psychrophiles like it cold. Most pathogens are Mesophiles - they like what we like.Yeasts and molds will grow under acid conditions.Clostridia will form toxins only under anaerobic conditions. Some bacteria can grow both with or without air.
What is the definition of psychrophiles?
The definition of psychrophiles are extremophilic organisms that are capable of reproduction in cold temperatures.
What microbes are in colds?
psychrophiles

What would be the effect of storage of the storage of the mince meat for 5 days in the refrigerator before assaying on the ratio of psychrophiles to mesophiles?
The population of psychrophiles should increase compared to mesophiles.
How does psychrophiles make their energy?
they share their dope says mr. dory
What conditions do psychrophiles live in?
Extreme cold. Typically the Arctic and Antarctic oceans.
How does psychrophiles make their energy happy?
they share their dope says mr. dory
Which group of bacteria is expected to cause spoilage to the food in fridge storage?
psychrophiles and psychrotrophs
What allows psychrophiles to live in their habitat?
because it has lived there for a long time and learnt what to do or maybe im wrong ;P
What are 4 types of archaebacteria?
There are only three main types of archaeobacteria. These are the crenarchaeota, euryarchaeota and the korarchaeota. The subtypes of archaebacteria include methanogens, halophiles, thermophiles and psychrophiles.
Would a hot tub likely contain psychrophilies?
No, Psychrophiles are microorganisms that live and grow better in temperatures that are about -10 to - 20°C; frozen condition not hot ones.
What is the use of a refrigerator in microbiology?
it is used to preserve media or chemical reagents. if microbial samples were present, it slows down its metabolism. if the microbial samples were psychrophiles, it enhances their growth.
