The possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of Wood-Plastic novolac has been proved by using Differential Scanning Calorimetry (DSC) and Fourier Transformed Infra Red (FT-IR) spectroscopy. Synthesis of novolac with different concentrations (10, 20 and 30 wt %) of water insoluble fraction were performed. It was found that mechanical p...

The objective of selecting strains Bacillus sp. has high activity in carbon metabolism for peat treatment, firstly focusing on the ability to degrade lignin, cellulose, phosphorus and protein. From gene pool, by surveying microbial capable degrading carbon-rich substrates including insoluble phosphate, proteolytic, we have identified two contain polyfermenticus subtilis strong metabolize decomp...

Abstract Phosphorus is an essential nutrient required by plants for their growth and development. Phosphates bioavailability in nature approximately 95-99% but insoluble, therefore the plant can not simply use them. The alternative to overcome phosphate deficiency utilizing solubilizing fungi. This research aimed at selecting characterizing fungi rhizosphere of saitomo taro ( Colocasia esculent...

Measurement of polymerization degree of condensed phosphates was examined by solid-state NMR. Broad peaks of the NMR of endand middle-PO4 groups of condensed phosphates were observed at about 1 and -20 ppm, respectively. The NMR. peak area ratio (Ro) of middle-PO4 group to end-PO4 group has the following relation with the polymerization degree (n) of polyphosphate: Ro (middle-PO4/end-PO4) = (n-...

In the rhizosphere, phosphorus (P) levels are low because of P uptake into the roots. Rhizobacteria live on carbon (C) exuded from roots, and may contribute to plant nutrition by liberating P from organic compounds such as phytates. We isolated over 300 phytate (Na-inositol hexa-phosphate; Na-IHP)-utilizing bacterial strains from the rhizosheath and the rhizoplane of Lupinus albus (L.). Almost ...

To elucidate the mechanism of mobilization of insoluble phosphates, a field trial and a split root experiment in a growth chamber were conducted. The results showed that a phosphorus (P)-efficient wheat genotype, Yanzhong 144 (YZ), transpired 50% less than a P-inefficient genotype, 80-55. At the grain-filling stage, the free water content in YZ’s rhizosphere was 2.4 times of that of 80-55’s. Wh...

X-ray microanalysis of unfixed frozen-dried cryosections, and of unfixed cryosections collected by a sucrose drop technique, revealed the presence of Ca, Mn, Fe, Ni, Cu and Zn (Period IV, Periodic Table) in association with the permanently condensed chromosomes of Prorocentrum micans. All of these metals, with the exception of Mn, routinely occurred in the chromatin of cells that had been fixed...

In order to determine the contribution of aquatic macrophyte communities on nutrition to sustain the high primary productivity of an estuary aquatic community, we analyzed the process of phosphorus release from sediments in aquatic macrophyte community in the estuary of the Chikugogawa River, South-Western Japan. Vertical profile of 4 PO  concentration and redox potential (Eh) of pore water in...
