TABLE 5.
Effect of chloroform fumigation on hydrogen uptake by material from the 0- to 2-cm interval of selected sitesa
| Site | Rate of H uptake (min−1)a
|
% Cellular contributions | |
|---|---|---|---|
| Control | Fumigated | ||
| I-C | 32.9 ± 3.5 | 8.7 ± 0.8 | 73.6 |
| II-A | 6.2 ± 0.4 | 1.1 ± 0.1 | 82.4 |
| II-C | 29.7 ± 2.1 | 12.8 ± 2.8 | 56.8 |
a
First-order uptake rate constants (mean ± 1 standard error) were determined in triplicate before and after fumigation.
b
The contribution of cells reflects the activity lost upon fumigation: [1 − (control − fumigation)/control]·100%.
