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,
Bread making experiment
Bread is a fermented food produced with flour as the main ingredient and yeast, sugar, fat and eggs as supplementary ingredients. After adding yeast into the mi
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
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
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
Linear plasmid DNA 5'-sticky end dephosphorylation assay
The 5' end of the plasmid DNA cut by restriction endonuclease has a phosphate group, and if this vector is used to directly transform E. coli, the chance of its
