Abstract The aim of this study was to isolate and characterize the Phosphate solubilizing bacteria from rhizosphere Zea mays L., Jeneponto Regency. This research conducted in several stages; i.e, sampling, medium preparation, sample dilution, isolation, characterization form gram staining, biochemical tests, quantitative tests phosphate solubility. Soil samples were diluted 0.9% NaCl soil conta...

A new and convenient method for the determination of P, was developed. Phosphomolybdate is measured calorimetrically, without reduction to molybdenum blue, by dissolving the whole assay mixture in acetone, where phosphomolybdate is bright yellow. The hydrolysis of acidlabile phosphates (e.g., creatine phosphate) causes no problems, because extra molybdate is complexed with citrate immediately a...

The essential steps of the novel non-mevalonate pathway of isopentenyl diphosphate and isoprenoid biosynthesis in plants are described. The first five enzymes and genes of this 1-deoxy-D-xylulose 5-phosphate/2-C-methyl-D-erythritol 4-phosphate (DOXP/MEP) pathway are known. The herbicide fosmidomycin specifically blocks the second enzyme, the DOXP reductoisomerase. The DOXP/MEP pathway is also p...

After a recent study, the pore water and high-resolution solid phase analyses as well as microbial investigations on the Namibian shelf indicate that sharp phosphate peaks, observed in 2-3 cm sediment depth, correspond to the depth where great sulfur bacteria are most abundant (Schulz and Schulz, 2005). Beside the well known connection between the benthic cycles of iron and phosphorus it could ...
