Hydrolysis of phytoglycolipid by barium hydroxide yielded the various products possible from cleavage of the phosphate diester bond (ceramide phosphate plus oligosaccharide and ceramide plus oligosaccharide phosphate). About 50% of the oligosaccharide was recovered as a phosphorus-free, amorphous solid, the analytical data for which suggested a hexasaccharide structure. Studies on the fractiona...

Understanding the diversity and community structure of arbuscular mycorrhizal fungi (AMF) is important for potentially optimizing their role in mining phosphorus (P) in agricultural ecosystems. Here, we conduct a comprehensive study to investigate the vertical distribution of AMF in a calcareous field and their temporal structure in maize-roots with fertilizer P application over a three-year pe...

The mechanism of DNA strand break induction due to K-shell photoabsorption of DNA constituent phosphorus was studied by computer simulation. Photon induced Auger process in DNA solution was modeled and introduced to the Monte Carlo simulation code DBREAK, which allows the estimation of DNA strand break production on pBR322 plasmid DNA in aqueous solution. The simulation was carried out for the ...

In previous studies (Labaw, Mosley, and Wyckoff, 1950a, b) from this laboratory we have shown that large yields of bacteriophage can be obtained from cultures of Escherichia coli which have been exposed to enough ultraviolet radiation to prevent their subsequent growth to form observable colonies when spread on fresh nutrient agar. In this work it was found that though the phosphorus metabolism...

The study was carried out during the period of 2019-2021 in experimental field IASS "Obraztsov chiflik" - Ruse a long-term stationary fertilizer trial with 4-pole crop rotation, including interchange corn, barley, beans and wheat, according to scheme Georges Ville three replications located Rümker. Fertilization options are individual combined application macroelements – nitrogen, phosphorus, p...

The effects of soil inoculation with phosphoriencontaining phosphate-dissolving bacteria (PDB) and/or magnesium (Mg) foliar application at the rates of 0, 0.5 and 1mM on growth, green pod and seed yields, and chemical constituents of Pisum sativum L. grown on a sandy calcareous soil were investigated. Results indicated that PDB and/or Mg significantly increased shoot length, number of branches ...

An ESR study on electron-capture phosphorus centered radicals trapped in single crystals of racand meso-1,2dimethyl-l,2-diphenyldiphosphine disulfide (MePhP(S)P(S)MePh) is reported. The principal values and axes of the g and hyperfine coupling tensors of the radical anions are determined. It is shown that X irradiation of the two diastereoisomeric compounds results in completely different radic...

Relevance. The effectiveness of fertilizers depends on the need plants for nutrients and ability soil to meet this need. According Research Institute Raw Materials Alcohol Industry, responsiveness chicory individual substances changes dramatically during growing season. In first period its development, responds sharply positively only phosphorus. future, phosphorus efficiency remains stable two...

• Value-added products was recycled from antibiotic mycelial dreg (AMD). Antibiotic residue in AMD removed after pyrolysis. N mainly distributed biochar and liquid, while P retained biochar. Low pyrolysis temperature benefits the recycling of P. The disposal by fully conform to related principles. utilization (AMD), which has been identified as a hazardous waste China, are serious concern becau...
