A Petri Dish (alternatively known as a Petri plate or cell-culture dish) is a shallow transparent lidded dish that biologists use to culture cells[1][2], such as bacteria, or small mosses.[3] It is the most common type of culture plate.

The preparation method is to wash the barley with water, remove dust, impurities and pods so as to prevent rot during germination. Then put the scouring barley kernels in the cylinder for 24 hours with clean water, and then wash it again. Pour it into the bamboo basket to control the water, and then put it into the cylinder. Cover it with a sack to keep it warm as soon as possible. The rooting time is determined by the room temperature, which takes about 72 hours in the cold days and 48 hours in the hot days. As long as two or three roots of fibrous roots grow on the grain, they can be packed in baskets with a thickness of 4 cm to 5 cm. Water is often sprinkled after installation, the purpose is to add water and cooling effect, to prevent too hot, once every 6 hours. After 24 hours of basket loading, the fibrous roots have grown long and the germs have been exposed. At this time, the wheat grains should be gently shaken and loosened. However, it still takes 6 hours to pour water once. At room temperature above 15°C and below 25°C, after one day the malt can grow to 0.5cm, you can start feeding, feed water on one side and continue to water, malt can be as long as 3cm. But don't make it grow too long, because when the color turns dark green, not only the vitamin content is reduced, but the taste is also bitter, the fiber is also thick, and loss of palatability, the quality of malt is also reduced.
Fermented feed Fermentation of concentrate feed to livestock and poultry is also a good way to increase the vitamins of livestock feed. Because a large number of yeasts are produced in fermented feeds, it can increase protein in feeds and increase vitamins. In particular, the increase in B vitamins is more significant.
The container is named after the German bacteriologist Julius Richard Petri.[4][5]
Penicillin, the first antibiotic, was discovered in 1929 when Alexander Fleming noticed that mold that had contamined a bacterial culture in a Petri dish had killed the bacteria all around it.
The Petri dish is one of the most common items in biology laboratories, and has entered popular culture. The term is often written in lower case, especially in non-technical literature
Germinating feed is usually germinated with barley, oats, mung beans, etc., which is rich in carotene and B vitamins. It is effective for young livestock and lactating dairy and male broilers.
