Some features of this site may not work without it. Nitrification is oxidation of ammonium to nitrate. The high rate of denitrification was inversly proportional to the rate of DNRA because the availability of carbon source.

Theduration of nitrification process in LLFR suspected to be influenced by the number ofbacteria, organic material and season. Some features of this site may not work without it. The results ofthe study will be utilizedas limnological database for development of conservation and restoration of Pesut habitat. More information and software credits.

Distribution of Nitrifying Bacteria in Floodplain Lake. Indonesian Journal of Biology. 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. The ammonium and nitrate availability measurements have been done before glyphosate application and at 7th, 14th and 28th days after. Generally, denitrification activity was the most dominant activity.

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.


Denitrification and disimilatory nitrate reduction to ammonium DNRA is the process of anaerobic nitrate reduction. The experiments were carried out using completely randomized design, with four level of glyphosate concentration, 0, 3. In addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were baktdri.

Abstract Nitrifying bacteria has an important role in oxidizing ammoniac to be nitrit which is required by plants. Show full item record. Contact Us Send Feedback. The sampel was taken at wildlife sanctuary of Ambawang mountain Kubu Raya district.

Nitrosomonas, Nitrobacter and Nitrosococcus were some types of bacteria that were pound in fibrik meanwhile in hemik, Nitrobacter and Nitrosocystis were identified. JavaScript is disabled for your browser.

At the same time soil pH, soil respiration rates and population Nitrification bacteria have been measured.

Latest Additions View items added to the repository in the nitrifikssi week.

As for the bacteria Nitrobacter sp. Lake Loa Kang is a fishery reserve locatedin a floodplain system of River Mahakam.

Collections UT – Biology []. The effect of glyphosate application on the activity of nitrification decreases when weed density increases.

Metadata Show full item record. Abstract Nitrogen is an abundant element in baktdri. Nitrification bacteria obviously overcome the effect ofglyphosate. While the number of isolates has result 9 isolatesobtained includes 5 isolates Nitrosomonas sp. The ammonium sulphate fertilizer equivalent to kg per hectare were given to the experimental area one week before glyphosate application treatment.


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.

This floodplain lakes consists of severalhabitat types among the others are backswamp deposit lakes represented by Lake LoaKang and Lake Balikpapan. In observation of cell morphology and gram staining of isolates nitrifying bacteria isolates derived niyrifikasi 6 were classified as gram positive and 3 were classifield as gram negative. 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.

Ex situ simulation of this biogeochemical cycle indicate a duration of 13 – 21 days tocomplete the nitrification process. The nitrifying bacteria functionalgroup that mediated the process can be detected and identified by enrichment culture. 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.
