Niko Siagkris-Seymour, Baker Fermentation Guru and Grain Junkie Niko Siagkris-Seymour provides an in-depth explanation of the science of spontaneous fermentation and baking in the centuries-old tradition of artisan breads. Homemade samples will be provided to accompany the lecture. Detroit City Distillery creates small batch artisanal whiskey, gin and vodka using the finest local ingredients sourced directly from farms near our distillery and tasting room located in Detroit's famed Eastern Market.
Hire Writer The first test used to confirm the presence of fermentation was to test for the presence of Carbon dioxide. This was carried out by checking the gas collectors, on the top of each bottle, for the presence of carbon dioxide gas. The second test performed used indicator paper to determine the pH of both samples.
Two pieces of indicator paper were dipped in each of the samples, and the color change was recorded.
The fourth test performed was a turbidity test to determine the absorbency of each sample. Five micrometers of each sample was placed in a test tube and diluted with five hundred micrometers of water. The test tubes were then placed in a spectrophotometer and the absorbency was recorded.
The Kefir sample had an inflated gas collector The milk sample had a deflated gas collector Figure 1 pH Observations: The indicator paper dipped in the Kefir had an orange color, correlating with a pH of 4.
The presence of bacteria was observed in the Kefir sample. The presence of bacteria was observed in the milk sample, but was a lower in amount than that of the Kefir sample. The Kefir sample was observed to have a higher absorbency compared to the milk sample.
The milk sample was observed to have a lower absorbency compared to the Kefir sample. The gas production test showed the Kefir sample produced gas while the milk sample did not. This was interpreted as an indication of fermentation, because carbon dioxide is a direct product of fermentation.
The pH test showed that the kefir sample was more acidic than the milk sample, which is exactly what was expected. This confirms the presence of fermentation due to the bacteria producing several different acids when fermenting the carbohydrates in milk.
The pH of the milk was neutral as expected. The turbidity test showed the Kefir sample to have a higher absorbency than the milk sample. This went exactly how we expected, and is used as confirmation of fermentation since the fermented product would have more bacteria present.
The Gram stain test showed that there were bacteria present in both the Kefir and milk samples, which was not an expected result.
Before conducting the experiment, milk was believed to contain no bacteria due to the bastardization process.Caleb O. Othieno, Tea Research Foundation of Kenya, PO Box , Kericho, Kenya.

A laboratory-scale fermentation system and its application to developing predictable regimes for the control of volatile ester formation at production scale Presenter: Terry W.
Bilverstone, The University of Nottingham, Nottingham, UK. Quantifying the purity of ethanol using different fermentation sources Michael Cermak, Jeremy Quinton Faculty Sponsor: Dr. Christopher Halsey Ethanol is a key component in the making of biodiesel in the world today.
Our goal is to reveal different sources of ethanol output and quantity if our modern day processes and purity for biodiesel can be. The green alga Chlamydomonas reinhardtii is a leading unicellular model for dissecting biological processes in photosynthetic eukaryotes.
However, its usefulness has been limited by difficulties in obtaining mutants in specific genes of interest. To allow generation of large numbers of mapped. Nov 19, · It is also possible that homofermentative LAB will consume a portion of the sugar before the Brett has a chance to produce CO2.
Yeast Fermentation Lab Report The purpose of this experiment was to observe the process in which cells must partake in a respiration process called anaerobic fermentation and as the name suggests, oxygen is not required. Caleb Lab Report Fermentation Essay. Transcript of Yeast Fermentation Lab Report. Chris Alleman, Rachel Poulsen, Spencer Koelsch, Jade Jones Class Period 6 Pre AP Biology Water Temperature and Its Effect on the Fermentation of Yeast Conclusion (Rachel) In this experiment, we tried to answer the question of whether the temperature of water affects the production of CO2 in a yeast. iTunes is the world's easiest way to organize and add to your digital media collection.

Re-yeasting is a very effective way to ensure proper CO2 levels in an aged sour beer. Others do take care to avoid oxygen exposure in the packaging process and report that purging bottles with CO 2 helps. 1 Karen Rasmussen Microbiology Lab Report 2 Dr.
