It is known that cells and organisms can indirectly "sense" changes in L-arginine availability via changes in the activity of various metabolic pathways. However, the mechanism(s) by which genes can be directly regulated by L-arginine in mammalian cells have not yet been elucidated. We investigated the effect of L-arginine in the in vivo model of peritoneal(More)
A red-pigmented, Gram-stain-negative, rod-shaped, aerobic bacterium, designated strain CCM 8646T, was isolated from stone fragments in James Ross Island, Antarctica. Strain CCM 8646T was able to grow from 10 to 40 °C, in the presence of up to 1 % (w/v) NaCl and at pH 7.0-11.0. Analysis of the 16S rRNA gene sequence placed strain CCM 8646T in the genus(More)
Four rod-shaped and Gram-stain-negative bacterial strains, CCM 8647, CCM 8649T, CCM 8643T and CCM 8648T, were isolated from rock samples collected on James Ross Island, Antarctica. Extensive biotyping, fatty acid profiling, chemotaxonomy, 16S rRNA gene sequencing and whole-genome sequencing was applied to isolates to clarify their taxonomic position.(More)
In this work, 84 isolates of aeromonads were isolated from water and clinical samples, identified, and characterized. Identification was based on routine phenotyping combined with multiplex PCR. In this study, multiplex PCR was retested and reevaluated and its identification key was enhanced by 17 newly described species and five subspecies. Identification(More)
Strain CCM 4446T, with notable biodegradation capabilities, was investigated in this study in order to elucidate its taxonomic position. Chemotaxonomic analyses of quinones, polar lipids, mycolic acids, polyamines and the diamino acid of the cell-wall peptidoglycan corresponded with characteristics of the genus Rhodococcus. Phylogenetic analysis, based on(More)
A taxonomic study performed on 17 Gram-stain-negative rod-shaped bacterial strains originating from the Antarctic environment is described. Initial phylogenetic analysis using 16S rRNA gene sequencing differentiated the strains into four groups belonging to the genus Pedobacter but they were separated from all hitherto described Pedobacter species. Group I(More)
