A glass Petri dish with culture. A Petri dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured, [1] [2] originally, cells of bacteria, fungi and small mosses. [3]
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2]
An agar plate is a Petri dish that contains a growth medium solidified with agar, used to culture microorganisms. Sometimes selective compounds are added to influence growth, such as antibiotics. [1] 96 pinner used to perform spot assays with yeast, fungal or bacterial cells
English: The Evolution of Bacteria on a “Mega-Plate” Petri Dish: Bacteria (white) grow on a large petri dish with increasing concentrations of antibiotic (trimethoprim) in bands towards the center. Evolution of antibiotic resistance can be seen as mutants with higher antibiotic resistance are able to colonise the more central regions.
The sample is spread across one quadrant of a Petri dish containing a growth medium. Bacteria need different nutrients to grow. Bacteria need different nutrients to grow. This includes water, a source of energy, sources of carbon, sulfur, nitrogen, phosphorus, certain minerals, and other vitamins and growth factors.
Phosphate solubilizing bacteria (PSB) are beneficial bacteria capable of solubilizing inorganic phosphorus from insoluble compounds. [1] P-solubilization ability of rhizosphere microorganisms is considered to be one of the most important traits associated with plant phosphate nutrition.
Petri dish/agar plate: to act as a supporting container to hold the culture medium in Platinum wire loop: used to inoculate test samples into culture media for bacterial or fungal cultures, antibiograms, etc.; sterilized by flaming to red hot before use Pre-sterilized disposable container: specimen collection
In microbiology, a culture plate is a low flat-bottomed laboratory container for growing a layer of organisms such as bacteria, molds, and cells on a thin layer of nutrient medium. The most common types are the petri dish [1] [2] and multiwell plates. [3]
