What do you use to inoculate agar plates and liquid broth? Inoculating loops and needles made of metal wire can be used to transfer bacteria from one medium to another, such as from the surface of an agar plate to a broth. Metal tools may be sterilized by heating them in the flame of a Bunsen burner.

How to inoculate microorganism with sterile broth?
Flaming the open end of the broth will keep it sterile. The broth moved up to the needle so that the tip of the needle is submerged while maintaining the original position of the needle. Swirling of the needle carefully can help the inoculation of the microorganism from the needle to the sterile broth.
How do you use lb + antibiotic agar agar?
Using a sterile pipette tip or toothpick, select a single colony from your LB agar plate . Drop the tip or toothpick into the liquid LB + antibiotic and swirl. Loosely cover the culture with sterile aluminum foil or a cap that is not air tight.
What is the purpose of LB agar plate?
Luria broth (LB) is a nutrient-rich media commonly used to culture bacteria in the lab. LB agar plates are frequently used to isolate individual (clonal) colonies of bacteria carrying a specific plasmid.
What do we use to inoculate our agar plates and liquid broth?
Inoculating loops and needles made of metal wire can be used to transfer bacteria from one medium to another, such as from the surface of an agar plate to a broth. Metal tools may be sterilized by heating them in the flame of a Bunsen burner.
What type of inoculation tool is used to inoculate a broth?
what tool might one use to inoculate a broth culture? An inoculating loop.
What device is used to inoculate the agar surface?
An inoculation loop is a handheld tool that ends in a small wire loop (Figure 1.6. 2). The loop can be used to streak microorganisms on agar in a Petri dish or to transfer them from one test tube to another.

It's always a good idea to select more than one single colony for inoculations.
What are inoculation tools?
An inoculation loop, also known as a smear loop, inoculation rod or microstreaker, is a simple tool used primarily by microbiologists to take and transfer a small sample (inoculum) of a microorganism culture, for example for stripping on a culture plate.
Which instrument should be used to inoculate an agar deep tube?
An inoculating needle is used for inoculating an agar deep. The agar deep medium is stabbed, not streaked. This technique is used in some biochemical tests to place the bacteria within the medium, rather than on the surface.

What are the methods of inoculation?
Different methods of inoculation include stab culture, slant culture, agar culture and broth culture.
What is the use of inoculating needle?
An inoculation needle is used in the transfer of microbial organisms from plate culture to needle by first sterilizing the needle to prevent contaminants. The lid of the agar plate culture is then removed to allow the needle access to the microorganisms cultured on the agar plate.
How do you inoculate a media?
Inoculate culture media directly by rolling the cannulae across the surface of a whole agar plate five times (avoiding the edges of the plate) or culture any blood, fluid or material contained in or on the specimen (see B 20 - Investigation of intravascular cannulae and associated specimens).

Background Information
Plasmids can carry one or more antibiotic resistance genes, which confer resistance to a specific antibiotic to the bacteria carrying them. The presence of an antibiotic resistance gene on a plasmids allows researchers to easily isolate bacteria containing that plasmid from bacteria that do not contain it by artificial selection (i.e.
Video
Watch the protocol video below to learn how to inoculate bacteria in liquid culture.
Protocol
Prepare liquid LB. For example, to make 400 mL of LB, weigh out the following into a 500 mL glass bottle:
Agar Plates
Agar plates are some of the most common media which are in use for growing bacteria and other microorganisms. A mixture of agar and nutrients necessary for bacterial growth. This is then poured into circular Petri dishes where the agar solution solidifies.
Broth Culture
An inoculation needle used in inoculating a sterile broth culture. Flaming the open end of the broth will keep it sterile. The broth moved up to the needle so that the tip of the needle is submerged while maintaining the original position of the needle.
Slant Culture
To inoculate a slant culture in a fishtail inoculation technique we use inoculation needle. After transferring the microorganisms from the original microbial culture to the inoculation needle the sterile slant culture is uncapped. The open end of the uncapped slant culture is then flamed.
Plate Culture
Inoculation of a plate culture uses a streaking technique to make a streak plate. The inoculation needle streaked across the plate in controlled directions, after lifting the lid so that it hovers above the sterile agar plate. Microbial aerosols created from the hitting of the inoculation tip to the sides of the agar plate.
Stab Culture
In inoculating a stab culture, an inoculation needle is an essential tool. Removal of a sterile stab culture cap is completed and the open end of the needle is flamed. The needle tip and length of the needle is pushed into the stab media until the needle reaches 0.5 inches away from the bottom of the stab media.
