Distribution of Nitrifying Bacteria in Floodplain Lake.

The lowest potential rate was DNRA. On 14th days after glyphosate application the effect of concentration 3. Results of the study showed that the numberof nitrifying bacteria is highest at connecting channel between floodplain lakes L.

From the results of isolation at 3 sampling locations obtained the average number of bacteria of each media, which is to the hitrifikasi Nitrosomonassp. Full text not available from this repository.

The nitrifying bacteria functionalgroup that mediated the process can be detected and identified by enrichment culture. Latest Additions View items added to the repository in the past week. While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp. Generally, denitrification activity was the most dominant activity.


In observation of cell morphology and gram staining of isolates nitrifying bacteria isolates derived nitrifying 6 were classified as gram positive and 3 were classifield as gram negative.

The purpose of this research to isolate the nitrifying bacteria in the rhizosphere of local aromatic rice that grown conventionally in the Tana Toraja. The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3.

Nitrosomonas, Nitrobacter and Nitrosococcus were some types of bacteria that were pound in fibrik meanwhile in hemik, Nitrobacter and Nitrosocystis were identified.

In addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were discovered.

Theduration of nitrification process in LLFR suspected to be influenced by the number ofbacteria, organic material and season. Information For Readers For Authors. Lake Loa Kang is a fishery reserve locatedin a floodplain nitgifikasi of River Mahakam. At the same time soil pH, soil respiration rates and population Nitrification bacteria have been measured.


The ammonium and nitrate availability measurements have been done before glyphosate application and at 7th, 14th and 28th days after. Denitrification and disimilatory nitrate reduction to ammonium DNRA is the process of anaerobic nitrate reduction.

Nitrification is one key ofmicrobiological process of nitrogen cycle in inland water. Contact Us Send Feedback. Abstract Nitrogen is an gakteri element in nature.

Nitrification bacteria obviously overcome the effect ofglyphosate. Observation and identification was implemented macroscopically, microscopically and biochemically. The effect of glyphosate application on the activity of nitrification decreases when weed density increases. The finding indicated that 5 genus of nitrifying bacteria had different level of maturity in peat soil.

The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. The ammonium sulphate fertilizer equivalent to kg per hectare were given to the experimental area one week before glyphosate application treatment. Isolation niteifikasi bacteria was conducted by serial dilution up to by using a specific medium nitrification.
