Regulatory aspects of ectoine biosynthesis in halophilic bacteria
Springer Science and Business Media LLC - Tập 79 - Trang 583-592 - 2010
I. I. Mustakhimov, A. S. Reshetnikov, V. N. Khmelenina, Yu. A. Trotsenko
In this review, the current concepts of metabolic and genetic regulation of the synthesis of ectoine and hydroxyectoine, widely distributed osmoprotectors of halophilic bacteria, are analyzed and generalized. Due to their water-retaining properties, these compounds can be used as multifunctional bioprotectants. The relevance of deciphering ectoine biosynthesis regulation at the levels of enzyme ac...... hiện toàn bộ
Diversity and dynamics of bacteriophages in horse feces
Springer Science and Business Media LLC - Tập 76 - Trang 236-242 - 2007
E. E. Kulikov, A. S. Isaeva, A. S. Rotkina, A. A. Manykin, A. V. Letarov
The complex cellulolytic microbial community of the horse intestines is a convenient model for studying the ecology of bacteriophages in natural habitats. Unlike the rumen of the ruminants, this community of the equine large intestine is not subjected to digestion. The inner conditions of the horse gut are much more stable in comparison to other mammals, due to the fact that the horse diet remains...... hiện toàn bộ

Biocrystalline structures in the nucleoids of the stationary and dormant prokaryotic cells
Springer Science and Business Media LLC - Tập 86 Số 6 - Trang 714-727 - 2017
Loiko, N. G., Suzina, N. E., Soina, V. S., Smirnova, T. A., Zubasheva, M. V., Azizbekyan, R. R., Sinitsyn, D. O., Tereshkina, K. B., Nikolaev, Yu. A., Krupyanskii, Yu. F., El’-Registan, G. I.
Compaction and biocrystallization of the nucleoid are presently considered as a necessary and important stage in the transformation of the cell ultrastructure during change of microbial cultures strategies from growth to survival. Nucleoid biocrystallization in the stationary phase cells is achieved due to structural regularity of the DNA complexes with the histone-like Dps protein. Our experiment...... hiện toàn bộ
Infection of Plants and Plant Tissue Cultures with Cyanobacteria–Bacteria Complexes
Springer Science and Business Media LLC - Tập 70 - Trang 299-305 - 2001
E. S. Lobakova, A. G. Shchelmanova, T. G. Korzhenevskaya, M. V. Gusev
The infection of tobacco, nightshade, rice plants, and their tissue cultures with the cyanobacteria–bacteria associative microsymbiont complexes (AMC) isolated from natural syncyanoses (the ferns Azolla pinnataand Azollasp. and the cycad Encephalartos ferox) was studied. The inoculation of the intact plants or their cuttings with AMC led to the colonization of the plant roots, stems, and leaves by...... hiện toàn bộ
Microbial processes at the aerobic-anaerobic interface in the deep-water zone of the black sea
Springer Science and Business Media LLC - Tập 69 - Trang 436-448 - 2000
N. V. Pimenov, I. I. Rusanov, S. K. Yusupov, J. Fridrich, A. Yu. Lein, B. Wehrli, M. V. Ivanov
Chemical and key microbiological processes (assimilation of carbon dioxide, oxidation and formation of methane, and sulfate reduction) occurring at the aerobic-anaerobic interface in the deep-water zone of the Black Sea were investigated. Measurements were taken at depths from 90 to 300 m at intervals of 5–10 m. The integral rate of the dark assimilation of carbon dioxide varied from 120 to 207 mg...... hiện toàn bộ
New antibiotics produced by Bacillus subtilis strains

I. A. Malanicheva, D. G. Kozlov, T. A. Efimenko, V. A. Zenkova, G. S. Katrukha, M. I. Reznikova, A. M. Korolev, L. N. Borshchevskaya, O. D. Tarasova, S. P. Sineokii, O. V. Efremenkova
Two Bacillus subtilis strains isolated from the fruiting body of a basidiomycete fungus Pholiota squarrosa exhibited a broad range of antibacterial activity, including those against methicillin-resistant Staphylococcus aureus INA 00761 (MRSA) and Leuconostoc mesenteroides VKPM B-4177 resistant to glycopeptide antibiotics, as well as antifungal activity. The strains were identified as belonging to ...... hiện toàn bộ
Streptomyces vilmorinianum sp. nov. Isolated from Soil of Zhengzhou
Springer Science and Business Media LLC - Tập 92 - Trang 334-341 - 2023
Z. X. Li, X. C. Si, Z. Y. Yuan, Y. P. Zhu, B. Y. Zhao, S. L. Zheng, H. L. Zhao
Streptomyces vilmorinianum sp. nov. (CGMCC.23383), is aerobic, gram-positive-staining bacterium isolated from soil of Zhengzhou, Henan Province in China. Granaticin was revealed among the secondary metabolites of S. vilmorinianum YP1 by high performance liquid chromatography (HPLC) and ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS-MS). Strain YP1 grew in a mineral mediu...... hiện toàn bộ
Green Approach: Characterization, Antibacterial, Antitumor and Detoxification Potentials of Exopolysaccharides-Mediated Silver Nanoparticles Produced by Penicillium citrinum AUMC 11627
Springer Science and Business Media LLC - - 2024
M. M. Housseiny, E. M. Fawzy, M. A. Abu-Tahon, W. E. Abdallah, O. M. El-Mahdy
Developing a green effective approach and a suitable applicative process for increasing the efficiency of microbial nanomaterial synthesis is an emerging prospect for future industrial production. This was accomplished by employing exopolysaccharides (EPS) to obtain potent silver nanoparticles using Penicillium citrinum (EPS−AgNPs) as a reducing and stabilizing agent. EPS−AgNPs were analyzed by UV...... hiện toàn bộ
Production of gaseous hydrocarbons by microbial communities of Lake Baikal bottom sediments
Springer Science and Business Media LLC - Tập 83 - Trang 798-804 - 2014
O. N. Pavlova, S. V. Bukin, A. V. Lomakina, G. V. Kalmychkov, V. G. Ivanov, I. V. Morozov, T. V. Pogodaeva, N. V. Pimenov, T. I. Zemskaya
Production of gaseous hydrocarbons by the microbial community of the Posolsky Bank methane seep bottom sediments (southern Baikal) was studied at 4°C. Formation of both methane and a heavier gaseous hydrocarbon, ethane, was detected in enrichment cultures. The highest methane concentrations (6.15 and 4.51 mmol L−1) were revealed in enrichments from the sediments from 55-cm depth incubated with sod...... hiện toàn bộ
