Bacterial isolation by inoculation with slanting medium method
This method is suitable for pure culture and preservation of strains, and can also be used for identification tests of urea and Kirschner's bisaccharides media.
Selection of viral transmission electron microscopy carrier grids and supporting membranes
Virus is a class of tiny sub-microscopic, intracellular specialized parasitic non-cellular organisms, the size range of only 20-200 nm, therefore, to understand
Experiments on the culture method of isolation of bacteria by plate delineation
This method is suitable for clinical specimens or other cultures mixed with many kinds of bacteria, which can be separated and cultured to obtain single colonie
Experiments on the splicing action of bacteria
Bacterial splicing is the phenomenon of recombination that occurs when the DNA of a donor bacterium is unidirectionally transferred to the recipient bacterium b
Experiments on the pathogenic effects of podocarpus
Bacterial pods are closely related to pathogenicity. When pods are present, they are pathogenic; when they are lost, pathogenicity decreases or disappears, due
Isolation experiments of drug-resistant mutant strains
Changes in the order of bases in a gene can lead to genetic variation in microbial cells. This variation can sometimes enable the cell to survive in a harmful e
Chicken embryo culture experiments of animal viruses
Chicken embryo culture is a culture method used to cultivate certain animal viruses that are sensitive to chicken embryo, and this method can be used for the is
Endotoxin assay
Endotoxin is a component of lipopolysaccharide (LPS) in the cell wall of Gram-negative bacteria, and lipid A is the active part. Individual Gram-positive bacter
