L. Tuominen et al., COMPARISON OF METHODS FOR INHIBITING BACTERIAL-ACTIVITY IN SEDIMENT, Applied and environmental microbiology, 60(9), 1994, pp. 3454-3457
Dilute formaldehyde was the most suitable treatment to inhibit sedimen
t bacteria, since bacterial activity remained low during long-term inc
ubations and the chemical changes in the sediment were minimal. The in
hibiting effects of HgCl2, autoclaving, and gamma radiation were dimin
ished during longer incubations; these treatments also caused increase
s in dissolved nutrients.
