A South San Francisco child enjoyed bath time at his home because of the colorful orange and red water. The water did not have t

his rusty color at its source, and the water department could not culture the Acidithiobacillus bacteria responsible for the rusty color from the source. How were the bacteria getting into the household water? What bacterial structures make this possible?

It oxidies iron and inorganic sulfur compounds. The oxidation process can be harmful, as it produces sulfuric acid, which is a major pollutant. It has been suggested that T. ferrooxidans forms a symbiotic relationship with members of the genus Acidiphilium, a bacterial capable of iron reduction. Other species of Thiobacillus grow in water and sediment; there are both freshwater and marine strains.

The bacteria are usually found in rivers, canals, mine drainage effluents and mining areas. So there may be some source of these bacilli near their house.They require inorganic sources to grow and contain an enzyme called ferrous oxidase that allows them to metabolize iron.

zzz [600]

Answer:

Bacteriophages have a lytic or lysogenic cycle.

5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?
dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.
