An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate. [1] [2] This process is called inoculation.
The inoculation loop is first sterilized by passing it through a flame. When the loop is cool, it is dipped into an inoculum such as a broth or patient specimen containing many species of bacteria. The inoculation loop is then dragged across the surface of the agar back and forth in a zigzag motion until approximately 30% of the plate has been ...
This is also known as inoculation, spawning or adding spawn. Its main advantages are to reduce chances of contamination while giving mushrooms a firm beginning. [3] [4] Definition of Spawn: Spawn is a type of medium present in mushroom tissue that propagates the fungus such as Trichoderma which is the root system of mushrooms. [5]
Serial passage is the process of growing bacteria or a virus in iterations. For instance, a virus may be grown in one environment, and then a portion of that virus population can be removed and put into a new environment.
The inoculation needle after incineration is cooled down on an uninoculated region of the agar plate culture. [1] Too much heat will kill off the inoculum during the direct contact of a flamed inoculation needle. [1] The inoculation needle is withdrawn from the agar culture after obtaining a small colony and the agar plate lid is then replaced.
Inoculation paired with other amendments can further improve conditions. Arbuscular mycorrhizal inoculation combined with compost is a common household amendment for personal gardens, agriculture, and nurseries. It has been observed that this pairing can also promote microbial functions in soils that have been affected by mining. [12]
Inoculation is the act of implanting a pathogen or other microbe or virus into a person or other organism. It is a method of artificially inducing immunity against various infectious diseases.
In biology, inoculum (pl.: inocula) refers to the source material used for inoculation. Inoculum may refer to: In medicine, material that is the source of the inoculation in a vaccine; In microbiology, propagules: cells, tissue, or viruses that are used to inoculate a new culture
