Importance of flaming the edges of the petri plates before and after pouring the media?
Flaming the edges of the petri plates before pouring the media helps to create a sterile environment by killing any microorganisms present on the surface. Flaming the edges after pouring the media helps to prevent contamination of the agar surface by airborne microorganisms during incubation.
Why does the agar plates has more colonies on after then before?
Agar plates typically show more colonies after incubation because the conditions are optimized for microbial growth, including the right temperature, moisture, and nutrients. During this time, individual microorganisms multiply through cell division, leading to the formation of visible colonies. Additionally, any dormant or slow-growing bacteria may become active and proliferate, contributing to the increased colony count. This process highlights the importance of suitable environmental factors for the growth of microorganisms.
Are waves created by tectonic plates?
Yes, and, no. Yes, waves are created by tectonic plates during an earthquake (When two or more tectonic plates rub together and make huge vibrations) and even cause tsunami waves. Waves are not formed when the plates are still, though.
Why are my blood agar plates showing no growth?
Check the ingredient i.e. salt concentration and also check whether the blood cell get lysed as some of the microbes need lysed blood cell and some need intact so depends upon needs of bacteria check your case and also see if you have taken a culture which should not be too old.
What happens during tectonics plates process?
happening during tectonics plates process is the 2 land part scratching togethere and they form like the plate tectonic theory that the 7 continent now is a 1 whole land in the past
Why are inverted plates during incubation?
Because during incubation moisture will form at the top of the petri dish. Inverting the dish prevents it from dropping into whatever you have in the petri dish.
Why are petri plates inverted for incubation?
it is to prevent the moisture formed due to condensation of the agar ,to mix with the components present in the petri plates, else causes contamination
Why did the instructions for making streak and spread plates emphasize inverting the plates before storing them for incubation?
inverting plate will allow fresh air mostly oxygen gas to pass through them and allow bacteria to grow
The use of plastic bags for anaerobic incubation?
For long incubation periods,esp. for spread plates ,the agar surface can be dehydrated and this can cause inhibition of low aw sensitive microorganism like gram- rod shape bacteria. For this reason the petridishes are packed in plastic bags
Why agar plates inverted during the incubation period?
Bacteria love to grow in moist damp places - if you haven't noticed, condensation causes water droplets to form on the top of the lid and if you incubated the plate with lid on top when the water runs down the sides of the plate it can easily contaminate your culture.
How much do bumper plates weigh compared to regular weight plates?
Bumper plates weigh the same as regular weight plates of the same size, but they are designed to be more durable and suitable for dropping during weightlifting exercises.
Importance of flaming the edges of the petri plates before and after pouring the media?
Flaming the edges of the petri plates before pouring the media helps to create a sterile environment by killing any microorganisms present on the surface. Flaming the edges after pouring the media helps to prevent contamination of the agar surface by airborne microorganisms during incubation.
What are charger plates typically used for?
Charger plates are used during formal dinners. They are decorative plates that are used not for food, but for effect. They make the table look pretty before the food is served.
What is the name of the top plates on a balance beam?
The top plates on a balance beam are called end plates. They are typically located at the ends of the beam and are used to stabilize and secure the beam in place during use.
