Phage examination and potency determination
Examination and potency determination of phage: It is easy to understand the characteristics of phage, rapid examination and isolation, and potency determinatio
Observational experiments on the ascospores of Saccharomyces cerevisiae
The formation of ascospores and their shape is an important basis for the classification of yeast. The formation of ascospores can only be observed in a part of
Morphological observation experiments of molds
Mold mycelium is thicker, the cells are easy to contraction deformation, and spores are easy to fly apart, so the specimen is commonly used lactic acid carbonat
Laboratory environment and human surface microorganism examination experiments
Experiments for the examination of microorganisms in the laboratory environment and on human surfaces facilitate (1) safety monitoring of microbiological levels
Direct yeast transformation of plasmids
Plasmid transformation can be used to: introduce an exogenous DNA molecule into a recipient cell to enable it to acquire a new genetic trait.
Drug susceptibility testing of bacteria
Drug sensitivity test is referred to as drug sensitivity test (or drug resistance test). Microbiological tests aimed at understanding the degree of sensitivity
Staining experiments of bacterial cell walls
Bacterial cell wall is very thin, the cell wall of Gram-positive bacteria is 20-30 nm, and the cell wall of Gram-negative bacteria is 10-13 nm.The main chemical
