Question

A waste product for cheese making is whey. You have been tasked with finding a use for the whey from Swiss cheese (aside from a dietary supplement for humans). You isolate a microbe that is genetically related to Lactobacillus. This microbe is able to grow exceptionally well on the whey when you allow for aeration of the culture - it grows weakly without aeration and the pH drops dramatically over time due to an acidic waste product. See Figure 1 and Table 1 for the structure of lactose and the composition of whey. When you sequence the genome you identify genes for Embden Meyerhoff Parnas as well as oxidoreductases and guinones, You also notice it produces an interesting antibiotic when grown in a closed batch system.

Explanation / Answer

Answer=

1] Lactose may be the carbon & energy source for newly isolated microbe described in the case study

2]In regard to its Carbon ,energy & electron usage this microbe is Chemoorganotroph

Chemoorganotrophs - Are microorganisms which oxidized the chemical bonds in organic compounds as their energy source .

They also attains the carbon molecules that they need for cellular function from these organic compounds

in this case study the microbe use lactose as energy source & lactose is organic compound

3] In addition to embden meyehoff pathway in this bacterium fermentation may be occure because it closely related to lactobacillus

4] This bacterium is capable of respiration only because it grow well on the whey when you allow aeration of the culture & grows weakly without aeration

Respiration is a oxidative process

& fermentation is anaerobic process
