A novel lipolytic enzyme-producing endophytic strain PC2 was successfully isolated from the seeds of an ideal bioenergy plant Pistacia chinensis Bunge. Based on the analysis of morphology and 16S rRNA sequence, bacterial strain PC2 was identified as a subspecies of Pseudomonas putida, therefore named as P. putida PC2. Whole-genome sequencing showed PC2 contained a 1224-nucleotide lipase gene (name...... hiện toàn bộ
Effect of the composition of the medium on the characteristics of polydisulfide bioantioxidantsSpringer Science and Business Media LLC - Tập 36 - Trang 385-393 - 2000
A. N. Eremin
Characteristics of polydisulfides of gallic acid (PDSG), 2-amino-4-nitrophenol (PDSANP), and biuret (PDSB) depending on the composition of the aqueous medium were studied. In contrast to PDSANP and PDSB, there was oxidation of PDSG with accumulation of products of polydisulfide transformation in the medium. The rate of PDSG autoxidation depended on pH on the concentration of polydisulfide and buff...... hiện toàn bộ
Autoantibodies to Human Thyroid Peroxidase in Immunoassay and Immunoaffinity ChromatographySpringer Science and Business Media LLC - Tập 38 - Trang 83-88 - 2002

A biochemical system of radioimmunoassay of human thyroid peroxidase (TPO) with the use of specific autoantibodies was developed for the first time. This system includes lyophilized preparations of human autoantibodies to TPO, radioiodinated TPO, standards prepared from pure TPO, and the solid-phase protein A as a precipitating agent. An analytical system was used to study the TPO distribution in ...... hiện toàn bộ
Jasmonate Signaling and Plant Adaptation to Abiotic Stressors (Review)Springer Science and Business Media LLC - Tập 57 - Trang 1-19 - 2021
Yu. E. Kolupaev, T. O. Yastreb
The role of jasmonic acid (JA) and jasmonate signaling in the regulation of plant adaptive responses to the action of stressors is reviewed. The synthesis of JA in plants and the main pathway for the transduction of jasmonate signals are briefly described. The effect of JA on the content of other signaling mediators (calcium ions, reactive oxygen species, nitric oxide, hydrogen sulfide, and carbon...... hiện toàn bộ
Rugulosuvines A and B, Diketopiperazine Alkaloids of Penicillium rugulosumand Penicillium piscariumFungiSpringer Science and Business Media LLC - Tập 37 - Trang 253-256 - 2001

Two diketopiperazine alkaloids, rugulosuvines A and B (tryptophan and phenylalanine are their precursors), were isolated and purified from a culture liquid of Penicillium rugulosumVKM F-352 and Penicillium piscariumVKM F-325 fungi. Physical and physicochemical studies showed the absolute structure of rugulosuvine A. The absolute structure of rugulosuvine B was demonstrated to be identical to that ...... hiện toàn bộ
Comparison of Leaching of Copper–Nickel Concentrates and Metallurgical Slag with Biogenic Ferric IronSpringer Science and Business Media LLC - Tập 58 - Trang 463-467 - 2022
N. V. Fomchenko, A. E. Panyushkina, V. S. Melamud, M. I. Muravyov
The leaching of nonferrous metals from copper–nickel sulfide concentrates and copper–nickel slags with ferric sulfate solution obtained by microbial oxidation of ferrous sulfate was studied. The process was carried out at 80°С, pH 1.15, and 9.8 g/L Fe3+. Most nickel was shown to be leached from the slags within 1.5 h. When copper–nickel concentrates were leached for 7 h, the maximum possible conce...... hiện toàn bộ
