KARAKTERISASI DAN KEPADATAN BAKTERI NITRIFIKASI PADA TINGKAT KEMATANGAN TANAH GAMBUT YANG BERBEDA DI KAWASAN HUTAN LINDUNG GUNUNG AMBAWANG KABUPATEN KUBU RAYA
ABSTRACT: Nitrifying bacteria
has an important role in oxidizing ammoniac to be nitrit which is required by
plants. The purpose of this study is to investigate character and density of
nitrifying bacteria at maturity level of peat soil. The sampel was taken at
wildlife sanctuary of Ambawang mountain Kubu Raya district. 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. Observation and identification was implemented macroscopically,
microscopically and biochemically. The finding indicated that 5 genus of
nitrifying bacteria had different level of maturity in peat soil. Nitrosomonas,
Nitrobacter and Nitrosococcus were some types of bacteria that were pound in
fibrik meanwhile in hemik, Nitrobacter and Nitrosocystis were identified. In
addition, in saprik, Nitrobacter, Nitrospina and Nitrosococcus were discovered.
The total density of nitrifying bacteria colonies in maturity level of peat
soil in fibrik, hemik and saprik was 160 x 105 CFU/g, 107,5 x 105 CFU/g, and 19
x 105 CFU/g.
