title: Comparison of methods for inhibiting bacterial activity in sediment.
abstract: Dilute formaldehyde was the most suitable treatment to inhibit sediment bacteria, since bacterial activity remained low during long-term incubations and the chemical changes in the sediment were minimal. The inhibiting effects of HgCl(2), autoclaving, and gamma radiation were diminished during longer incubations; these treatments also caused increases in dissolved nutrients.
