How would you sterilize a heat-sensitive growth medium containing thermoduric bacteria?
with a filter
What bacteria are more sensitive to the culture process?
There is no one answer to this question as different bacteria have different sensitivity to the culture process. However, some bacteria are generally more sensitive to the culture process including those that are fastidious (require specific nutrients or growth conditions), those with delicate cell membranes, and those that are susceptible to contamination by other microorganisms. Examples of bacteria that may be more sensitive to the culture process include species of Mycobacterium and Neisseria.
How does lemon kill bacteria?
Lemon juice can inhibit some bacteria if they are sensitive to lower (acidic) pH. As lemon juice is an acid. But there are very high numbers of bacteria in lemon wedges when tested. See link below:
Why the frequency of pencillin resistant bacteria can change over time within the population?
Due to bacteria reproducing quickly, their enormous numbers and the rapid transfer of genetic data there is great scope for mutation to occur. These newly formed bacteria are often non-sensitive to existing antibiotics.
Can a bacteria be parasitic?
Some of them are and some are not. The ones that feed on other organism and cause them harm are considered to be true parasites. Others are free living and others live within or on another organism but don't harm them like true parasites. For example, the bacteria in our digestive tracts or the ones on our skin are this kind.
Are non-dividing bacteria sensitive to penicillin?
No, it is not. Only dividing bacteria are sensitive to penicillin, as it usually work by either damaging the harmful dividing bacteria's cell membrane or preventing its growth.
Is biofilm sensitive to antibiotics?
Biofilms are generally thousands of times less sensitive to antibiotics than planktonic bacteria.

Will extreme cold temperatures kill viruses on surfaces?
Some viruses are sensitive to cold- most bacteria are.

What is urine culture and sensitivity?
Urine culture is when a doctor orders a urine specimen to be evaluated in a lab to determine exactly what kind of bacteria are living in it and causing problems. "Culture" means to grow, and they literally grow the bacteria so that they can test different antibiotics on it. Some antibiotics may kill the bacteria, and some antibiotics have no effect on the bacteria. This is the "sensitivity" part. If a bacteria is sensitive to an antibiotic, it would be a good choice for treatment of the infection. If it is not sensitive, the it is resistant to the antibiotic and it won't produce a cure.
What is worn away if someone has a cavity?
the tooth enamel has eroded, leaving your tooth sensitive and vulnerable for bacteria to creep into your teeth, especially if it is your back molars. The bacteria will get into your tooth and cause decay, thus, a cavity.
What is genone spray used for?
Genone spray is used to treat skin lesions in dogs. The lesions are created by bacteria that are sensitive to gentamicin.

What growth phase will gram - positive bacteria be most susceptible to penicillin?
Bacteria are most sensitive to antibiotics during the exponential stage (rapid growth).
Does V. cholerae die in acid?
Because V. cholerae is sensitive to acid, most cholera-causing bacteria die in the acidic environment of the stomach
