Nitrogen cycle occur in nature in aerobic and anaerobic conditions. The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3. Bacterial isolates obtained observed macroscopically and microscopically. In addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were discovered.

Distribution of Nitrifying Bacteria in Floodplain Lake. Some features of this baktsri may not work without it. Information For Readers For Authors. Collections UT – Biology [].

Theduration of nitrification process in LLFR suspected to be influenced by the number ofbacteria, organic material and season. This study was aimed to reveal feature of nitrification process in several floodplainhabitat types of Lake Loa Kang Fishery Reserve LLFR gakteri with emphasize on thespatial distribution pattern of nitrifying bacteria.

Full text not available from this repository. Abstract Nitrifying baketri has an important role in oxidizing ammoniac to be nitrit which is required by plants. This two floodplain lakes exchange water with RiverMahakam and one of its tributary, the River Pela. The purpose of this study is to investigate character and density of nitrifying bacteria at maturity level of peat soil.

Nitrifikasi – Wikipedia bahasa Indonesia, ensiklopedia bebas

The ammonium sulphate fertilizer equivalent to kg per hectare were given to the experimental area one week before glyphosate application treatment. On 14th days after glyphosate application the effect of concentration 3.


Some features of this site may not work without it.

This floodplain lakes consists of severalhabitat types among the others are backswamp deposit lakes represented by Lake LoaKang and Lake Balikpapan. Results of the study showed that the numberof nitrifying bacteria is highest at connecting channel between floodplain lakes L.

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

View original from e-journal. Nitrification is one key ofmicrobiological process of nitrogen cycle in inland water. Generally, denitrification activity was the most dominant activity. Jurnal ini memuat hasil The results indicate that the effect of glyphosate on nitrification activity depend on the concentration of glyphosate application and weed density. 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.

Isolation of bacteria was conducted by serial dilution up to by using a specific medium nitrification. Nitrosomonas, Nitrobacter and Nitrosococcus were some types of bacteria that were pound in fibrik meanwhile in hemik, Nitrobacter and Nitrosocystis were identified. High demands of nitrogen because nitrogen is an integral component of many constituent compounds such chlorophyll, protein, enzymes, nucleic acids and nucleotides.

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 ammonium and nitrate availability measurements have been done before glyphosate application and at 7th, 14th and 28th days after.

Observation and identification was implemented macroscopically, bitrifikasi and biochemically.


Investigation of the bakheri of glyphosate on nitrification activity in the soil have been done on soil arable. The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. JavaScript is disabled for your browser. User Username Password Remember me.


Ex situ simulation of this biogeochemical cycle indicate a duration of 13 – 21 days tocomplete the nitrification process. Show full item record. The nitrifying bacteria functionalgroup that mediated the process can be detected and identified by enrichment culture. Nitrification is oxidation of ammonium to nitrate. The results ofthe study will be utilizedas limnological database for development of conservation and restoration of Pesut habitat.

At the same time soil pH, soil respiration rates and population Nitrification bacteria have been measured. The effect of glyphosate application on the activity of nitrification decreases when weed density increases. Keywords nitrifying bacteria, density, maturity level of peat soil. Nitrification bacteria obviously overcome the effect ofglyphosate. While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp.

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 number of nitritation and nitratation bacteria inLake Loa Kang in the dry season is smaller compared to the number in rainy season. From the results of isolation at 3 sampling locations obtained the average number of bacteria of each media, which is to the bacteria Nitrosomonassp.

This element is an essential nutrient for plant growth.
