Potential activity of methane and ammonium oxidation by methanotrophic communities from the soda lakes of southern Transbaikal
Springer Science and Business Media LLC - Tập 69 - Trang 460-465 - 2000
Radioisotopic measurements of the methane consumption by mud samples taken from nine Southern Transbaikal soda lakes (pH 9.5–10.6) showed an intense oxidation of methane in the muds of Lakes Khuzhirta, Bulamai Nur, Gorbunka, and Suduntuiskii Torom, with the maximum oxidation rate in the mud of Lake Khuzhirta (33.2 nmol/(ml day)). The incorporation rate of the radioactive label from14CH4 into14CO2 ...... hiện toàn bộ
The Finding of the Yeast Species Saccharomyces bayanusin Far East Asia
Springer Science and Business Media LLC - Tập 72 - Trang 738-743 - 2003
The genetic analyses of nine Far East Asian Saccharomyces isolates allowed us to identify three species (S. cerevisiae, S. paradoxus, and S. bayanus). The occurrence of the last species in Far East Asia was shown for the first time. A new methodology for the molecular genetic differentiation of Saccharomyces sensu stricto species is described. The ecogeographical distribution of Saccharomyces yeas...... hiện toàn bộ
Expression Vector pLF22 for Lactic Acid Bacteria
Springer Science and Business Media LLC - Tập 73 - Trang 170-175 - 2004
The construction of the expression vector pLF22 for lactic acid bacteria is described. The vector contains a replicon of the cryptic plasmid pLF1311 from Lactobacillus fermentum and a multiple cloning site of the lacZ′ gene integrated with the plasmid rep operon. Such a construction of the vector provides for the constitutive transcription of the cloned sequences lacking the terminators of transcr...... hiện toàn bộ
Butyric acid bacteria of the genus Clostridium in the bottom sediments of inland basins of different types
Springer Science and Business Media LLC - Tập 74 - Trang 104-110 - 2005
The cell numbers and ecological characteristics of the distribution of certain species of butyric acid bacteria (BABs) of the genus Clostridium in the bottom sediments of inland basins of different types were studied using the optimal nutrient media. The seasonal dynamics of clostridial vegetative cells and spores in sediments with different ecological conditions were revealed. The cell numbers of...... hiện toàn bộ
Investigation of the dark metabolism of acetate in photoheterotrophically grown cells ofRhodospirillum rubrum
Springer Science and Business Media LLC - Tập 69 - Trang 7-12 - 2000
The mechanism of the aerobic dark assimilation of acetate in the photoheterotrophically grown purple nonsulfur bacteriumRhodospirillum rubrum was studied. Both in the light and in the dark, acetate assimilation inRsp. rubrum cells, which lack the glyoxylate pathway, was accompanied by the excretion of glyoxylate into the growth medium. The assimilation of propionate was accompanied by the excretio...... hiện toàn bộ
Characterization of Thermophilic Proteolytic Spore-Forming Bacteria from a Geothermal Site in Lithuania Based on 16S rDNA RFLP and ITS-PCR Analyses1
Springer Science and Business Media LLC - Tập 71 - Trang 712-716 - 2002
Forty-two strains of gram-positive, aerobic, heterotrophic, obligately thermophilic, spore-forming bacteria were isolated from a geothermal site near the Baltic Sea in Lithuania. All of the strains were able to hydrolyze collagen and/or casein. Since characteristics of proteolytic activity are correlated with taxonomic positions of bacteria, the strains were grouped on the basis of molecular biolo...... hiện toàn bộ
The Penicillium commune Thom and Penicillium clavigerum Demelius Fungi Producing Fumigaclavines A and B
Springer Science and Business Media LLC - Tập 72 - Trang 149-151 - 2003
The type strains Penicillium clavigerum VKM F-447 and P. commune VKM F-3233 are found to produce fumigaclavines A and B. Of the seven other strains of these species, only two strains, P. commune VKM F-3088 and F-3491, possess the ability to synthesize these alkaloids. It is suggested that the five other strains under study either lost such an ability or require very specific conditions for the syn...... hiện toàn bộ
Effect of vitamin concentration on the synthesis of lactate, ethanol, pyruvate, and ethyl acetate in cells of the yeast Dipodascus magnusii
Springer Science and Business Media LLC - Tập 77 - Trang 430-435 - 2008
In the yeast Dipodascus magnusii, which is auxotrophic for thiamine and biotin, during cultivation on glucose with excessive thiamine concentration, pyruvate metabolism was shown to result in the synthesis of fermentation products, namely, ethanol and, to a lesser extent, lactate. Substantial synthesis of ethyl acetate was also observed under these conditions. Introduction of nicotinic acid (NA) i...... hiện toàn bộ
Bio-Synthesis of Gold Nanoparticles by Fusarium oxysporum and Assessment of Their Conjugation Possibility with Two Types of β-Lactam Antibiotics without Any Additional Linkers
Springer Science and Business Media LLC - - 2018
In the present study, biosynthesis of gold nanoparticles (GNPs) by Fusarium oxysporum was carried out and their conjugation possibility with two β-lactam antibiotics was evaluated. F. oxysporum was cultured and the fungal culture supernatant was subjected to the 1 mmol final concentration of chloroauric acid solution. The produced GNPs were analyzed using visible spectrophotometer, X-ray diffracti...... hiện toàn bộ
