Spatial distribution and inhibition by ammonium of methane oxidation in intertidal freshwater marshes
Article Abstract:
A research was conducted to examine the vertical distribution in the sediment and inhibition by ammonium of methane oxidation in intertidal marshes utilizing slurry incubation methods. A Carlo-Erba high-resolution MEGA 5340 gas chromatograph was utilized to characterize methane. Results suggested that the vertical distribution of methane oxidation in intertidal marshes may be determined by hydrological conditions that change with distance from a tidal river rather than by the dominant type of present vegetation.

Nitrate-reducing bacteria on rat tongues
Article Abstract:
Rat tongues sections in a microbial growth media were analyzed to map or identify the nitrite-producing microorganisms on the tongue surface and to determine nitrite reduction velocities by nitrite-producing bacteria. Analysis of tongue sections in nutrient agar and blood agar growth media indicated the presence of similar microbial populations composed mainly of Streptococcus and Staphylococcus species. Nitrite production in the tongue sections was also affected by changes in nitrite dietary intake.

Effects of nitrite availability and the presence of Glyceria maxima on the composition and activity of the dissimilatory nitrite-reducing bacterial community
Article Abstract:
The effects of Glyceria maxima and nitrite availability on species composition were analyzed in a nitrite-reducing bacterial community. The population of potential nitrite-reducing bacteria and nitrite-reducing activity in the rhizosphere were increased in sediments containing high levels of nitrite. Furthermore, Glyceria maxima controlled the composition of the nitrite-reducing community in sediments with limited nitrite levels.
