Generally, denitrification activity nitrifikadi the most dominant activity. 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 bacteria Nitrosomonassp.

The effect of glyphosate application on the activity of nitrification decreases baakteri weed density increases. Some features of this site may not work without it. In addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were discovered. The lowest potential rate was DNRA. This two floodplain lakes exchange water with RiverMahakam and one of its tributary, the River Pela. Jurnal baktdri memuat hasil Nitrogen cycle occur in nature in aerobic and anaerobic conditions.

Bacterial isolates obtained observed macroscopically and microscopically. Abstract Nitrogen is an abundant element in nature. Theduration of nitrification process in LLFR suspected to bakreri influenced by the number ofbacteria, organic material and season. Water samplings are conducted for three times inthose were in dry season June ,transitional August and the rainy Sept.


Keywords nitrifying bacteria, nitridikasi, maturity level of peat soil. More information and software credits. Research on the isolation of nitrifying bacteria in the rhizosphere of local aromatic rice Oryza sativa L. Some features of this site may not work without it. Indonesian Nitdifikasi of Biology.

Distribution of Nitrifying Bacteria in Floodplain Lake. The purpose of this study is to investigate character and density of nitrifying bacteria at maturity level of peat soil. The results ofthe study will be utilizedas limnological database for development of conservation and restoration of Pesut habitat.

Nitrifikasi – Wikipedia bahasa Indonesia, ensiklopedia bebas

The high rate of denitrification was inversly proportional to the rate of DNRA because the availability of carbon source. This element is an essential nutrient for plant growth. The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. The number of nitritation and nitratation bacteria inLake Loa Kang in the dry season is smaller compared to the number in rainy season.

Nitrification bacteria obviously overcome the effect ofglyphosate. View original from e-journal. High demands of nitrogen because nitrogen is an integral component of many constituent compounds such chlorophyll, protein, enzymes, nucleic acids and nucleotides. Denitrification and disimilatory nitrate reduction to nitrifiikasi DNRA is the process of anaerobic nitrate reduction.

This floodplain lakes consists of severalhabitat types among the others are backswamp deposit lakes represented by Lake LoaKang and Lake Balikpapan. Full nitrifi,asi not available from this repository.


The results indicate that the effect of glyphosate on nitrification activity depend on the concentration of glyphosate application and weed density. In observation of cell baktei and gram staining of isolates nitrifying bacteria isolates derived nitrifying 6 were classified as gram positive and 3 were classifield as gram negative. While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp.


Abstract Nitrifying bacteria has an important role in oxidizing ammoniac to be nitrit which is required by plants. JavaScript is disabled for your browser. Investigation of the effect of nitriikasi on nitrification activity in the soil have been done on soil arable.

Lake Loa Kang is a fishery reserve locatedin a floodplain system of River Mahakam.

The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3. Isolation of bacteria was conducted by serial dilution up to by using a specific medium nitrification.

This study was aimed to reveal feature of nitrification process in several floodplainhabitat types of Lake Loa Kang Fishery Reserve LLFR system with emphasize on thespatial distribution pattern of nitrifying bacteria.

On 14th days after glyphosate application the effect of concentration 3.
