Pontibacter beigongshangensis sp. nov., Isolated from the Mash of Wine
Abstract A Gram-negative, aerobic, oval-shaped, and light red pigmented bacterium, designated T6-1T, was isolated from the mash of wine collected from a wine-making laboratory simulated fermenter located in Beijing, China. The optimal growth of T6-1T occurred at 30 °C, pH 7.0 with 1% NaCl. The sole respiratory quinone was menaquinone-7 (MK-7). The principal cellular fatty acids (>5%) were iso-C15:0, iso-C17:0 3OH, C16:1 ω5c, and iso-C17:0. The major polar lipids were PE (phosphatidylethanolamine),...

Enhanced Production of Shigella flexneri Polysaccharide from a Newly Devised Silicate Method as a Potential Vaccine Conjugate
Abstract Conventional glycoconjugates are prepared with polysaccharides (PS) isolated from bacterial sources by fermentation technique. This approach has some major challenges like lower yield of PS, impurities and usage of hazardous chemicals. Reports on efficient and enhanced production of PS from Shigella flexneri is meager in literature. Hence, in the current study, three different types of media namely Yeast extract medium, Shigella sonnei-defined medium and synthetic medium...

Diversity of Archaea and Its Correlation with Environmental Factors in the Ebinur Lake Wetland
Abstract The diversity and community composition of archaea in soil samples from three wetlands (SP1, SP2, and SP3) of Ebinur Lake were studied by constructing 16S rDNA cloning library. The correlation between the diversity of archaea and soil environmental factors was analyzed by CANOCO software. The aim of this study was to reveal the differences of community structures of archaea in different sample sites, to provide a theoretical basis for further study on degradation and...

Antibiotic Resistance of LACTOBACILLUS Strains
Abstract The study provides phenotypic and molecular analyses of the antibiotic resistance in 20 Lactobacillus strains including 11 strains newly isolated from fermented plant material. According to the results of disc diffusion method, 90% of tested lactobacilli demonstrated sensitivity to clindamycin and 95% of strains were susceptible to tetracycline, erythromycin, and rifampicin. Ampicillin and chloramphenicol were found to inhibit all bacteria used in this study. The vast...

Characterization and Whole Genome Sequencing of AR23, a Highly Toxic Bacillus thuringiensis Strain Isolated from Lebanese Soil
Abstract The demand for sustainable and eco-friendly control methods of pests and insects is increasing worldwide. From this came the interest in Bacillus thuringiensis, an entomopathogenic bacterium capable of replacing chemical pesticides. However, the possibility of pests developing resistance to a particular strain may impair its use, and there is a need to identify novel strains of this species as potential commercial biopesticides. B. thuringiensis sv. israelensis is one...

Using the IPTG-Inducible P grac 212 Promoter for Overexpression of Human Rhinovirus 3C Protease Fusions in the Cytoplasm of Bacillus subtilis Cells
Abstract Expression and secretion of recombinant proteins in the endotoxin-free bacterium, Bacillus subtilis, has been thoroughly studied, but overexpression in the cytoplasm has been limited to only a few proteins. Here, we used the robust IPTG-inducible promoter, Pgrac212, to overexpress human rhinovirus 3C protease (HRV3C) in the cytoplasm of B. subtilis cells. A novel solubility tag, the N-terminal domain of the lysS gene of B. subtilis coding for a lysyl-tRNA synthetase...

In-Vitro Prebiotic Analysis of Microbiota Accessible Pectic Polysaccharides
Abstract Pectin is a diverse polysaccharide comprising of polygalacturonic acid, rhamnogalactouronan, and neutral polysaccharides (arabinan and arabinogalactan) as side chains or branches. They are resistant to salivary amylase and gastric juice. In the present study the prebiotic potentials of different pectic derived substrates were performed by using intestinal cultures and measuring the growth, change in pH and short chain fatty acid, (SCFA) production. Arabinan, arabinogalactan,...

Wickerhamomyces kurtzmanii sp. nov. An Ascomycetous Yeast Isolated From Crater Lake Water, Da Hinggan Ling Mountain, China
Abstract One novel ascomycetous yeast strain TF5-16-2 was isolated from water samples of Tuofengling crater lake located in Da Hinggan Ling Mountain, in the Inner Mongolia province of China. Morphological, physiological characteristics, as well as phylogenetic analyses of D1/D2 domains of the large subunit rRNA (LSU), ITS region, small subunit rRNA (SSU), and elongation factor-1α (EF-1α) were performed and finally confirmed the phylogenetic placement of strain TF5-16-2 in the...
