Bacterial strain Bacillus sp. VT-8 was shown to use trinitrotoluene (TNT) as the sole source of carbon, nitrogen, and energy, as well as to carry out its co-oxidation. Resistance of Bacillus sp. VT-8 to high TNT concentrations was shown. Efficient detoxification of TNT-contaminated soil and water samples was demonstrated. This strain may be recommended for(More)
MALDI mass spectra were generated for the type strain of Arthrobacter crystallopoietes VKM Ac-1107T and for closely related (99.6–100% 16S rRNA gene similarity) halotolerant Arthrobacter strains, as well as for some other Arthrobacter species. Results of the cluster analysis of the spectra were in agreement with the genotypic characteristics of bacteria(More)
Sixty years after the seminal Miller-Urey experiment that abiotically produced a mixture of racemized amino acids, we provide a definite proof that this primordial soup, when properly cooked, was edible for primitive organisms. Direct admixture of even small amounts of Miller-Urey mixture strongly inhibits E. coli bacteria growth due to the toxicity of(More)
Efficiency of MALDI mass spectrometry for differentiation between phenotypic phase variants (in colony morphology and virulence/avirulence) was investigated for saprotrophic and opportunistically pathogenic bacteria of five genera (Acinetobacter, Arthrobacter, Rhodococcus, Corynebacterium, and Escherichia). Analysis of MALDI spectra (on the SA and HCCA(More)
Identification of species constituting Rana esculenta complex represents a certain problem as two parental species Rana ridibunda and Rana lessonae form their hybrid R. esculenta, while external signs and sizes of the members of this complex are intersected. However the composition of skin secretion consisting mainly of peptides is different for the species(More)
