Howdy there!
Negative control for a fermentation lab should have the substrate in the vessel, and it should be very sterile so no contamination doesn't happen (make sure to label them vessels well). Secondly, the negative control vessel should not be inoculated with the microbe, like yeast, in it at all because you want no response. If there is a response, it could be contamination or you mistakenly inoculated with the microbe which fermented the substrate.
Hope this helped you plenty! 😄

What is the result of sugar fermentation of s.tyhii?
Negative
Does enterococcus faecalis have a positive methyl red test?
Enterococcus faecalis typically does not produce significant amounts of acid from glucose fermentation, so it usually gives a negative result in the methyl red test, which detects mixed acid fermentation.
What are the two types of fermentation and why each is necessary?
Aerobic fermentation and anaerobic fermentation.
What are the two types of anaerobic fermentation's?
Lactic Acid Fermentation and Alcoholic Fermentation.
A mildly toxic by product of alcohol fermentation?
Acetaldehyde is a mildly toxic byproduct of alcohol fermentation. It is responsible for some of the negative effects associated with excessive alcohol consumption, such as headaches and nausea. Acetaldehyde is further metabolized into acetic acid, which is then broken down by the body.
What is the result of sugar fermentation of s.tyhii?
Negative
Can you add more yeast during fermentation to enhance the fermentation process?
Adding more yeast during fermentation can help enhance the fermentation process by increasing the rate of fermentation and potentially producing a higher alcohol content in the final product. However, adding too much yeast can lead to off-flavors and other negative effects, so it is important to carefully monitor and control the amount of yeast added.
Why does pseudomonas give negative reactions on all the fermentations?
Pseudomonas bacteria typically give negative reactions in fermentation tests because they are mostly aerobic bacteria and do not ferment carbohydrates like other bacteria. Instead, they carry out oxidative metabolism using organic compounds as their energy source. As a result, they do not produce the byproducts associated with fermentation reactions, leading to negative results in fermentation tests.

What is the significance of the heat of fermentation in the process of wine production?
The heat of fermentation in wine production is important because it helps regulate the fermentation process. The heat generated during fermentation helps to control the temperature, which is crucial for the growth of yeast and the development of flavors in the wine. Maintaining the right temperature ensures a successful fermentation process and the production of high-quality wine.
