Show full item record. In addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were discovered. The nitrifying bacteria functionalgroup that mediated the process can be detected and identified by enrichment culture. JavaScript is disabled for your browser. Contact Us Send Feedback. The results ofthe study will be utilizedas limnological database for development of conservation and restoration of Pesut habitat.

Observation and identification was implemented macroscopically, microscopically and biochemically. More information and software credits. Ex situ simulation of this biogeochemical cycle indicate a duration of 13 – 21 days tocomplete the nitrification process. The lowest potential rate was DNRA.

This study aims to measure the potential rate of nitrification, denitrification, and DNRA and measure the abundance of bacteria in the rubber plantations in Jambi.

The proses of isolation was conducted by pour plate method that applying spesific media of nitrification and total plate account was used to calculate the density of bacteria. Isolation of bacteria was conducted by serial dilution up to by using a specific medium nitrification. Indonesian Journal of Biology. On 14th days after glyphosate application the effect of concentration 3. The number of nitritation and nitratation bacteria inLake Loa Kang in the dry season is smaller nitrifikasu to the number in rainy season.


While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp. The purpose of this research to isolate the nitricikasi bacteria in the rhizosphere of local aromatic rice that grown conventionally in the Tana Toraja. Collections UT – Biology []. The nitrifikaei indicated that 5 genus of nitrifying bacteria had different level of maturity in peat soil.

The effect of glyphosate application on the activity of nitrification decreases when weed density increases.

Nitrifikasi – Wikipedia bahasa Indonesia, ensiklopedia bebas

Nitrogen cycle occur in nature in aerobic and anaerobic conditions. JavaScript is disabled for your browser. Download full text Bahasa Indonesia, 11 pages. Distribution of Nitrifying Bacteria in Floodplain Lake.

Jurnal ini memuat hasil View original from e-journal. Results of the bakteei showed that the numberof nitrifying bacteria is highest at connecting channel between floodplain lakes L.

The ammonium sulphate fertilizer equivalent to kg per hectare were given to the experimental area one week before glyphosate application treatment.

Nitrifikqsi Loa Kang is a fishery reserve locatedin a floodplain system of River Mahakam. This two floodplain lakes exchange water with RiverMahakam and one of its tributary, the River Pela. Full text not available from this repository. Search Repository Search the repository using bakterk full range of fields.


Generally, denitrification activity was the most dominant activity. High demands of nitrogen because nitrogen is an integral component of many constituent compounds such chlorophyll, protein, enzymes, nucleic acids and nucleotides.

Information For Readers For Authors. Theduration of nitrification process in LLFR suspected to be influenced by the number ofbacteria, organic material and season. This floodplain lakes consists of severalhabitat types among the others are backswamp deposit lakes represented by Lake LoaKang and Lake Balikpapan. Some features of this site may not work without it. In observation of cell morphology and gram staining of baktteri nitrifying bacteria isolates derived nitrifying 6 were classified as gram positive and 3 were classifield as gram negative.


Research on the isolation of nitrifying bacteria in the rhizosphere of local aromatic rice Oryza sativa L. Abstract Nitrogen is an abundant element in nature.

Nitrification is oxidation of ammonium to nitrate.
