Why are fermentation tubes evaluated at 24 and 48 hours?

What would happen if an organism used up all the carbohydrate in a fermentation tube?

What would the organism use for energy?

What color would the indicator be then?

Summary Introduction

To analyze:

Fermentation tubes are evaluated at 24 and 48 hours. If an organism used up all carbohydrate in fermentation tube, then what happens and the organism use for energy and the color the indicator shows.

Introduction:

Fermentation is a process that breakdown large and complex sugar into smaller molecules with the help of bacteria and yeast. This process is used to make beer, alcohol, and fermented drinks.

Explanation of Solution

The process occurs in a lack of oxygen known as the anaerobic process as well as produces a significant amount of ATP. Its product is carbon dioxide, lactic acid, and ethanol. The process is very useful in wine as well as beverage industries.

Beer is the product of fermentation that is consumed as an alcoholic beverage. The flavoring of beers is done with hops that usually add bitterness as well as a natural preservative. Fermentation results in natural carbonation within the beer. It contains around four percent to six percent alcohol.

Fermentation can take place without or with the presence of oxygen as well the incubation periods that are prolonged results in the growth of bacteria oxidatively on peptone immediately after consuming the carbohydrate supplied.

A neutralization reaction will take place when an organism will use all the present carbohydrates. The organism will start using peptone as an energy source. The color of the indicator will turn red.

Conclusion

Thus, Fermentation can take place without or with the presence of oxygen as well as the incubation periods that are prolonged results in the growth of bacteria oxidatively on peptone immediately after consuming the carbohydrate supplied.

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
