Fermentation Process In Yeast

A. Purpose: The purpose of this experiment is to observe the fermentation process in yeast and how yeast reproduces through budding. The way yeast reproduces according to Exploring Creation With Biology 2nd Edition is: Most yeasts have a form of asexual reproduction, called budding, at their disposal. When a yeast buds, the nucleus of the cell reproduces inside a single cell.

According to MicroPop yeast can reproduce sexually in this way: In sexual reproduction, a single yeast cell undergoes meiosis and produces haploid spores; these spores can recombine with other haploid spores, producing a diploid cell – the yeast’s “normal” state.

And lastly stated by BBC: Like bacteria, yeast cells reproduce asexually. However, they do this by producing a bud. This is a new cell that eventually breaks away from the parent cell. The growth rate of a yeast

Conclusions: The fermentation process was evident when the specific odor was emitted from the mixture. When yeast undergoes fermentation it produces alcohol and carbon dioxide, these substances were obvious in the smell. The budding, however, could only be observed under magnification so a microscope was needed. When observed under a microscope the buds were clearly evident when the yeast cells grouped together. The budding process could then be observed.

The experiment could be improved in a number of ways, a couple being: Using more powerful microscope. A more powerful microscope could have revealed the budding process even further, perhaps even the growth of the bud. Letting the mixture sit for a longer period of time. This could have revealed the later stages of the budding process.and the result of yeast's asexual production.

This experiment can allow further research on how to manipulate the budding process in various ways to benefit humans. The budding process has already been used to make alcohol and allow bread to rise, but scientists may be able to find other ways to use
