Why are resistant spores useful to bacteria?
Resistant spores are a survival mechanism for bacteria in harsh conditions. They protect the bacteria's genetic material from damage and allow them to remain dormant until conditions improve. This increases the chances of the bacteria's survival and enables them to re-establish themselves when conditions become favorable again.
What happens to spores during the frozen storage?
Spores can survive frozen storage as they are highly resistant to cold temperatures. Freezing can result in a state of dormancy for the spores until they are exposed to more favorable conditions that allow for germination and growth.
Tyndallization is the process of repeated boiling and cooling to destroy spores?
Tyndallization involves intermittent boiling of a substance to eliminate heat-resistant bacterial spores. By allowing spores to germinate before the next boiling cycle, it helps to ensure that all spores are eventually destroyed over several cycles.
How many times more resistant were B megaterium spores than s aureus vegetative state?
Bacillus megaterium spores are typically thousands of times more resistant to harsh conditions compared to the vegetative state of Staphylococcus aureus. This increased resistance is due to the protective structures and dormancy of the spore form, allowing it to survive in unfavorable environments until conditions are more conducive for germination.
Do some bacteria surround themselves with a tough resistant wall and become spores that can survive dryness and low temperatures but die in boiling water?
Yes, some bacteria can form spores when conditions are unfavorable for growth, such as dryness or low temperatures. These spores have a tough resistant wall that protects them from harsh conditions but they can be killed by boiling water due to the high temperature denaturing their essential proteins and enzymes.
What are the advantage and disadvantage of reproducing by spores?
An advantage to reproducing through spores is that it can be done asexually. A disadvantage is that the spores will be clones of the original organism, leaving them vulnerable.
What is the most resistant form of bacterial life?
spores
What do viruses do when they enter the body's cells?
create resistant spores
What is true about spores?
heat resistant, and will germinate when conditions are favorable
Is bacterial spores the most resistant life form?
The most resistant organism in the healthcare environment is the bacterial spor
What is advantage of asexual spores?
They have the advantage of multiplying by itself. It does not need a partner to reproduce. :)
Why are resistant spores useful to bacteria?
Resistant spores are a survival mechanism for bacteria in harsh conditions. They protect the bacteria's genetic material from damage and allow them to remain dormant until conditions improve. This increases the chances of the bacteria's survival and enables them to re-establish themselves when conditions become favorable again.
Which microbial forms are most resistant to disinfectants?
Spores, such as those produced by Clostridium and Bacillus species, are the most resistant microbial forms to disinfectants. Spores have a protective outer layer that makes them highly resistant to harsh environmental conditions, including disinfection processes.
Which scientist discovered heat resistant bacterial spores?
Ferdinand Cohn, a German biologist, is credited with the discovery of heat-resistant bacterial spores in the late 19th century. He identified these spores as being able to survive high temperatures and coined the term "endospore" to describe them.
Why spores resistant to desication?
When harsh conditions exist, the spores will enter dormancy, and will only resume activity or growth when favorable conditions exist.
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.
Which of the following microorganisms is resistant to the antimicrobial effects of alcohol-based hand rub?
Bacterial spores
