Ethanol fermentation experiment
Under anaerobic conditions, the role of yeast in the fermentation of hexose to produce ethanol and CO2 is called ethanol fermentation. The yeast protozoa used i
Experimental production of single-cell proteins by brewer's yeast culture
Single-cell proteins are mycobacterial proteins obtained by culturing single-celled microorganisms. Single-cell microorganisms such as yeast, filamentous fungi,
Determination of lactic acid bacteria in yogurt
Active yogurt requires control of the ratio of various lactic acid bacteria, which have complex nutritional requirements, requiring carbohydrates, amino acids,
Tests for pathogenic Escherichia coli in foodstuffs
The test of pathogenic bacteria in food mainly includes the test of various pathogenic bacteria in food raw materials and food, such as Staphylococcus aureus, S
Bacterial endotoxin detection assay
Enterobacteriaceae are mostly gram-negative bacilli with endotoxin. If they cause sepsis, meningitis and other infections, endotoxin can be detected in blood, c
Cotton plug making experiment
The role of cotton plugs is twofold: one is to prevent contamination by stray bacteria, and the other is to ensure good aeration. Therefore, the quality of the
Experiment for the determination of coliforms in foodstuffs
Coliform refers to a group of Gram-negative non-spore-forming bacilli that can ferment lactose, produce acid and gas, and are aerobic and partially anaerobic. T
Plasmid DNA high-frequency transformation of Escherichia coli experiments
After the preparation of the receptor cells, the next step is the transformation of plasmid DNA into E. coli cells. However, it is important to note that the re
