Bacterial lawn

Bacterial lawns can be produced manually by evenly spreading a high amount of bacteria onto an agar plate using a sterile cotton swab or a Drigalski spatula. Alternatively an automated machine can be used such as a spiral plater where the plate is rotated and the sample is spread evenly using an automated dispenser. They may also be produced using the "pour plate" technique in which a concentrated inoculum of the appropriate bacteria are mixed with melted agar and spread evenly over the surface of a Petri dish. == See also ==
