Are most spores easily killed?
No, They are not.
Why you sterlize at 121 Celsius temp for 15 minutes in autoclave?
The sterilisation temperature is defined by the spores of the Geobacillus stearothermophilus. The spores have a D-value of 1,5 min @ 121°C. D-value means decimal reduction criteria, so it means, that after a treatment of 1,5 min (90 sec) at 121°C 90% of the bacillus spores have "died". For your process that means a 10x 90% reduction, a 10D concept. This means after 15 min @ 121°C 99,99999999% of the spores of G. stearothermophilus are "gone". Usual, the food industry demands commercial sterility, which is defined with a 12D concept. The regular sterilization requirement is usually 20min @121°C (or 5min @ 135°C). Where is your 15min@121°C sterization concept used? Cheers, Abraxas
Bacterial spores die at what temperature?
Spores are hard dormant state of bacteria which can resist even high temprature and pressure but most of them die at temp 100oC or higher when boil for hour or two at 15lbps
What are the structures inside the moss capsule called?
spores
Does algae hav spores or seeds?
nope
Does spores cause sweet curdling and bloating in UHT packs?
Sweet curdling could be caused by growth of spores that were not killed during sterilization and packaging of the product. These spores germinate during storage in UHT products causing instability and bloating.
Can spores survive high temperature?
It depends on the temperature, but at high oven temperature some do, but the majority are killed.
What technique is most effective in destroying spores in a medical laboratory?
Sterilization
If a person wants to make a room free from microbes and their spores what sterilization method would you advice him to use?
dry heat sterilization
What is the difference between pasteurization and sterilization?
The pasteurization is carried out for a prolonged time at around 170°F and is supposed to kill only heat susceptible organisms and their spores, while sterilization works at a temperature of 250°F and is supposed to kill all organisms.
Why is survival of bacillus and clostridium used as an index of sterilization?
Both of these produce very resistant spores. If these spores are no longer alive, then nothing else can be, either.
To fully eliminate all infectious microorganisms which of the following measures must be used?
Sterilization, includes spores
How are microorganisms controlled?
Sterilization-treatment that kills or removes all living cells including viruses and spores . johnnny
