Part 1

Which strain of bacteria has the highest C-ThOD? Which strain has the lowest C-ThOD? What can you infer, if anything, about the relationship between the percentage of carbon in a bacterial strain and C-ThOD based on this data?

Part 2


Which strain of bacteria has the highest N-ThOD? Which strain has the lowest N-ThOD? What can you infer about the relationship between the percentage of nitrogen in a bacterial strain and N-ThOD based on this data?

Explanation / Answer

the strain with highest C-ThOD is the strain 1 and lowest C-ThOD is bacterial strain 4 , these values are interfered with the inorganic compounds it determines that the total organic carbon vavlue for the strain 1 is higher because of the higher oxygen demand it refects the contamination

the bacterial strain with highN-ThOD is strain 5 , lowest N-ThOD is the strain   strain 4 it tell about the nitrogen fixation the bacteria , lower nitrogen fixation it shows the nitorgen exchage in diffrent strains , highest percentage shows more nitrogen exchange
