The formation of hydroxyectoine in the industrial ectoine producer Halomonas elongata was improved by the heterologous expression of the ectoine hydroxylase gene, thpD, from Streptomyces chrysomallus. The efficient conversion of ectoine to hydroxyectoine was achieved by the concerted regulation of thpD by the H. elongata ectA promoter.
میکروارگانیسم های نمک دوست، تحمل کننده نمک و غیر نمک دوست نقش مهمی در پاک سازی زیستی و تبدیلات زیستی عناصر فلزی سمی در محیط های آلوده دارند. شناسایی سویه های مقاوم به فلز و الگوهای حذف فلزی، اولین قدم در به کارگیری آن ها در فرایندهای پاک سازی زیستی است. در این مطالعه، حذف تلوریت و اثر اکسی آنیون های سمی سلنو اکسی آنیونی و ارسنات، در باکتری نمک دوست نسبی (H. elongate DSM 2581) ، تحمــل پذیـــر ...
Halomonas zhanjiangensis Chen et al. 2009 is a member of the genus Halomonas, family Halomonadaceae, class Gammaproteobacteria. Representatives of the genus Halomonas are a group of halophilic bacteria often isolated from salty environments. The type strain H. zhanjiangensis JSM 078169(T) was isolated from a sea urchin (Hemicentrotus pulcherrimus) collected from the South China Sea. The genome ...
Genetic and morphological divergence and phylogenetic relationships of Scorpaeniformes fish including two genera and six species, Helicolenus dactylopterus, Scorpaena maderensis, Scorpaena porcus, Scorpaena elongata, Scorpaena scrofa, Scorpaena notata, living in the Mediterranean Sea, were investigated with morphological and mitochondrial 16S rDNA sequence data. The mean nucleotide diversity wa...
The validity and authorship of Parapercis elongata are discussed. Although Fourmanoir (1967) has been considered to be the author of P. elongata, Fourmanoir (1965) satisfies the nomenclatural requirements associated with the availability of species names and P. elongata Fourmanoir, 1965 has priority over P. elongata of Fourmanoir, 1967. Although the holotype of P. elongata was not able to be co...
In this study, the intergeneric hybrids F1, F2, BC1F1, BC1F2, and BC2F1 from Elytrigia elongata and Triticum aestivum crosses were produced to study their chromosome pairing behavior. The average E. elongata chromosome configuration of the two F1 hybrids agreed with the theoretical chromosome configuration of 21I+7II, indicating that the genomic constitution of this F1 hybrid was ABDStStEeEbEx....
The role of choline in osmoprotection in the moderate halophile Halomonas elongata has been examined. Transport and conversion of choline to betaine began immediately after addition of choline to the growth medium. Intracellular accumulation of betaine synthesized from choline was salt dependent up to 2.5 M NaCl. Oxidation of choline was enhanced at 2.0 M NaCl in the presence or absence of exte...
O presente trabalho descreve a elucidação estrutural de uma nova β-lapachona tipo naftoquinona, isolada a partir das raízes de Distictella elongata. A nova substância, apresentando fórmula molecular C 16 H 16 O 6 , foi identificada como sendo 4,7-diidróxi-10-metóxi-2,2-dimetil3,4-diidro-2H-benzo[h]cromeno-5,6-diona, de acordo com os dados obtidos por meio de análises espectrométricas. A elucida...
The genus Neisseria contains at least eight commensal and two pathogenic species. According to the Neisseria phylogenetic tree, commensals are basal to the pathogens. N. elongata, which is at the opposite end of the tree from N. gonorrhoeae, has been observed to be fimbriated, and these fimbriae are correlated with genetic competence in this organism. We tested the hypothesis that the fimbriae ...
Neutrophils and macrophages, as key mediators of inflammation, have defined functionally important roles in mammalian tissue repair. Although recent evidence suggests that similar cells exist in zebrafish and also migrate to sites of injury in larvae, whether these cells are functionally important for wound healing or regeneration in adult zebrafish is unknown. To begin to address these questio...
