Karakter dan Potensi Inokulum Bakteri Fosfat dalam Melepaskan Fosfor
Abstrak: Soil bacteria group
which can release soil P-adsorbed is phosphate bacteria (PB). PB can release
soil P-adsorbed through: 1) acidification, 2) chelating 3) ligand exchange 4)
mineralization and 5) compete colloid sorption site. PB have a potential to
release soil P-adsorbed. This study was aimed to determining the character and
PB inoculant potential in soil P-adsorbed release. The results of BLASTn PB
showed that isolate 1 was Pseudomonas
trivialis, isolate 5 was Pseudomonas putida and
isolate 9 was Pseudomonas fluorescens. Based on the growth curve on day
5th (the end log. phase) population of Pseudomonas trivialis was 1010 CFU/mL,
Pseudomonas putida was 1014 CFU/mL and Pseudomonas fluorescens was 1017 CFU/mL.
Storage inoculant PB population decrease 97-84 % and 80-65 % PB lowering
capabilities.
