If the plates are unused, just wrap them up and throw them out. They aren't hazardous.
If they are used, you need to decontaminate them before disposal. If you don't have access to an autoclave, my recommendation would be to open them in a big beaker or other big container and submerge them in full strength bleach for a few hours to overnight (wear gloves). You can dispose of the bleach down the sink and them re-close the plates, wrap them in saran wrap and throw them out. Its not a perfect solution, but for three plates it will do.
In biology, BHI plates are plates consisting of Brain Heart Infusion (BHI) agar. This is a general purpose nutrient medium recommended for the cultivation and isolation of a variety of microorganisms, including bacteria, yeasts, and molds.
Corynebacterium xerosis typically grows on nutrient agar.
Labels should be written on the bottom of the agar plate. Write the label using a marker on the agar side, being careful not to write on the lid or cover of the plate. This ensures that the label remains visible and does not interfere with the growth of microorganisms on the agar surface.

Land plates are called continental plates. Sea plates are called oceanic plates.
To prewarm agar plates, simply place them in a 37°C incubator for about 30 minutes before use. This ensures that the agar solidifies evenly and prevents condensation from forming on the plates when they are inoculated. Always handle prewarmed plates carefully to maintain sterility.
Unopened agar plates are typically referred to as "sterile agar plates."
Agar plates should be disposed of in biohazard waste bins to prevent contamination and following appropriate safety protocols. Ensure that the plates are sealed in a plastic bag before disposal to minimize the risk of spreading any potential contaminants. Contact your laboratory or institution for specific guidelines on the disposal of agar plates.
Agar plates should be inoculated using a zig-zag motion across the surface of the media to evenly distribute the microbial sample and promote colony growth. This technique helps prevent overcrowding of colonies and facilitates the isolation of individual colonies for further analysis or study.
Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.

Placing the inoculated molten agar cultures in an ice water bath helps in rapid solidification by quickly lowering the temperature of the agar. This is important to prevent the growth of unwanted microbes that may be present in the environment during the cooling process. Rapid solidification also helps to ensure that the agar solidifies evenly, allowing for proper growth of the desired microbial cultures.
The agar dilution test is a method used in microbiology to determine the minimum inhibitory concentration (MIC) of an antimicrobial agent against a particular microorganism. It involves placing different concentrations of the antimicrobial agent on agar plates inoculated with the microorganism and observing which concentration effectively inhibits its growth. The MIC is the lowest concentration of the antimicrobial agent that prevents visible growth of the microorganism.
Nutrient agar plates: used for general growth of most bacteria. Blood agar plates: used to differentiate bacteria based on their ability to hemolyze red blood cells. MacConkey agar plates: used to differentiate lactose-fermenting bacteria from non-lactose fermenters based on their ability to grow and ferment lactose.
Agar plates and Petri dishes are both used in laboratory experiments for growing microorganisms. The main difference between them is that agar plates are the medium used to grow the microorganisms, while Petri dishes are the containers that hold the agar plates. This impacts their use in experiments because agar plates provide a solid surface for the microorganisms to grow on, while Petri dishes provide a sterile environment for the agar plates to be placed in. This allows for the controlled growth and observation of microorganisms in a laboratory setting.
If by inoculated you mean used, here is my answer if that is true; streak plates need to be dry because the powder left behind may react and change color to whatever that liquid is on the streak plate.
