The finding indicated that 5 genus of nitrifying bacteria had different level of maturity in peat soil. Ex situ simulation of this biogeochemical cycle indicate a duration of 13 – 21 days tocomplete the nitrification process.

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 nitridikasi sampling locations obtained the average number of bacteria of each media, which is to the bacteria Nitrosomonassp. JavaScript is disabled for your nitritikasi. Some features of this site may not work without it.

On 14th days after glyphosate application the effect of concentration 3. Bacterial isolates obtained observed macroscopically nitrifokasi microscopically. While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp. The purpose of this study is to investigate character and density of nitrifying bacteria at maturity level of peat soil. At the same time soil pH, soil respiration rates and population Nitrification bacteria have been measured.

This two floodplain lakes exchange water with RiverMahakam and one of its tributary, the River Pela. Collections UT – Biology []. Metadata Show full nitricikasi record.


The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district. Some features of this site may not work without it. This element is an essential nutrient for plant growth. 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. Full text not available from this repository. High demands of nitrogen because nitrogen is an integral component of many constituent compounds such chlorophyll, protein, enzymes, nucleic acids and nucleotides.

Abstract Nitrogen is an abundant element in nature. Search Repository Search the repository using a full range of fields. Nitrogen cycle occur in nature in aerobic and anaerobic conditions. Generally, denitrification activity was the most dominant activity.

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

Nitrifikasi – Wikipedia bahasa Indonesia, ensiklopedia bebas

Observation and identification was implemented macroscopically, microscopically and biochemically. This floodplain lakes consists of severalhabitat types among the others are backswamp deposit lakes represented by Lake LoaKang and Lake Balikpapan.

In addition, in saprik, Nitrobacter, Nitrospina bakeri Nitrosococcus were discovered. Results of the study showed that the numberof nitrifying bacteria is highest at connecting channel between floodplain lakes L.

Abstract Nitrifying bacteria has an important role in oxidizing ammoniac to be nitrit which is required by plants. The nitrifying bacteria functionalgroup that mediated the process can be detected and identified by enrichment culture. Research on the isolation of nitrifying bacteria in the rhizosphere of local aromatic rice Oryza sativa L. The purpose of this research to isolate the nitrifying bacteria in the rhizosphere of local aromatic rice that grown conventionally in the Tana Toraja. Theduration of nitrification process in LLFR suspected to be influenced by the number ofbacteria, organic material and season.


Nitrification is one key ofmicrobiological process of nitrogen cycle in inland water.

Denitrification and disimilatory nitrate reduction to ammonium DNRA is the process of anaerobic nitrate reduction. Keywords nitrifying bacteria, density, maturity level of peat soil. The effect of glyphosate application on the activity of nitrification decreases when weed density increases.

Isolation of bacteria was conducted by serial dilution up to by using a specific medium nitrification.

Show full item record. As bakeri the bacteria Nitrobacter sp. 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. Latest Additions View items added to the repository in the past week. Jurnal ini memuat hasil Indonesian Journal of Biology.

More information and software credits. The lowest potential rate was DNRA.


The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3. The results indicate that the effect of glyphosate on nitrification activity depend on the concentration of glyphosate application and weed density. Information For Readers For Authors.
