Denitrification and disimilatory nitrate reduction to ammonium DNRA is the process of anaerobic nitrate reduction. Indonesian Journal of Biology.

The ammonium sulphate fertilizer equivalent to kg per hectare were given to the experimental area one week before glyphosate application treatment. JavaScript is disabled for your browser.

The number of nitritation and nitratation bacteria inLake Loa Kang in the dry season is smaller compared to the number in rainy season.

Water samplings are conducted for three times inthose were in dry season June ,transitional August and the rainy Sept. From the results of isolation at 3 sampling locations obtained the average number of bacteria of each media, which is to the bacteria Nitrosomonassp.

Investigation of the effect of glyphosate on nitrification activity in the soil have been done on bakterk arable.


Isolation of bacteria was conducted by serial dilution up to by using a specific medium nitrification. Nitrification is oxidation of ammonium to nitrate. The purpose of this research to isolate the nitrifying bacteria in the rhizosphere of local aromatic rice that grown conventionally in the Tana Toraja.

Research on the isolation of nitrifying bacteria in the rhizosphere of local aromatic rice Oryza sativa L.

Nitrogen cycle occur in nature in aerobic and anaerobic conditions. Collections UT – Biology []. The nitrifying bacteria functionalgroup that mediated the process can be detected and identified by enrichment culture.

Some features of this site may not work without it. Metadata Show full item record. Abstract Nitrogen is an abundant element in nature. Abstract Nitrifying bacteria has an important role in oxidizing ammoniac to be nitrit which is required by plants. User Username Password Remember me. Nitrification is one key ofmicrobiological process of nitrogen cycle in inland water. Some features of this site may not work without it. The lowest potential rate was DNRA. Observation and identification was implemented macroscopically, microscopically and biochemically.

This two floodplain lakes exchange water with RiverMahakam and one of its tributary, the River Pela. The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3.

Nitrifikasi – Wikipedia bahasa Indonesia, ensiklopedia bebas

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

Jurnal ini memuat hasil The high rate of denitrification was inversly proportional to the rate of DNRA because the availability of carbon source. The effect of glyphosate application on the activity of nitrification decreases when weed density increases.

The ammonium and nitrate availability measurements have been done before glyphosate application and at 7th, 14th nitrifikzsi 28th days after. While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp. Latest Additions View items added nihrifikasi the repository in the past week. Ex situ simulation of this biogeochemical cycle indicate a duration of 13 – 21 days tocomplete the nitrification process.

This floodplain lakes consists of severalhabitat types among the others are backswamp deposit lakes represented by Lake LoaKang and Lake Balikpapan. On 14th days after glyphosate application the effect of concentration 3.
