Principle and Interpretation
MB Growth Medium is a minimal defined media for the growth of Schizosaccharomyces pombe. Yeasts are unicellular eukaryotes and extensively studied model organism in molecular genetics. The fission yeast Schizosaccharomyces pombe is a model eukaryote which is very useful in studies of cell cycle and chromosome dynamics. These cells maintain their shape by growing through the cell tips and divide by medial fission to produce two daughter cells of equal sizes that makes them a powerful tool in cell cycle research. It was first developed as an experimental model in the 1950's for studying genetics (1, 2) and for studying the cell cycle (3, 4). MB Growth Medium is used for the maintenance and propagation of S. pombe in various molecular microbiology procedures. It functions as a defined medium for fission yeast growth and it contains glucose and other supplements. Glucose serves as the carbon source.
