| antibiofilm activity of coral-associated bacteria against different clinical m serotypes of streptococcus pyogenes. | streptococcus pyogenes is the frequent cause of purulent infections in humans. formation of a biofilm is one of the important aspects of its pathogenicity. streptococcus pyogenes biofilm communities tend to exhibit significant tolerance to antimicrobial challenge during infections. exploring novel targets against biofilm-forming pathogens is therefore an important alternative treatment measure. we attempted to screen marine bacteria, especially coral-associated bacteria (cab), for antibiofilm ac ... | 2009 | 19845763 |
| complete genome sequence of bacillus horikoshii strain 20a from cuatro cienegas, coahuila, mexico. | we sequenced the bacillus horikoshii 20a genome, isolated from sediment collected in cuatro cienegas, mexico. we identified genes involved in establishing antagonistic interactions in microbial communities (antibiotic resistance and bacteriocins) and genes related to the metabolism of cyanophycin, a reserve compound and spore matrix material potentially relevant for survival in an oligotrophic environment. | 2017 | 28751383 |
| efficacy of ph elevation as a bactericidal strategy for treating ballast water of freight carriers. | treatment of ship ballast water with sodium hydroxide (naoh) is one method currently being developed to minimize the risk to introduce aquatic invasive species. the bactericidal capability of sodium hydroxide was determined for 148 bacterial strains from ballast water collected in 2009 and 2010 from the m/v indiana harbor, a bulk-freight carrier plying the laurentian great lakes, usa. primary culture of bacteria was done using brain heart infusion agar and a developmental medium. strains were ch ... | 2015 | 26257948 |
| bacillus mesophilus sp. nov., an alginate-degrading bacterium isolated from a soil sample collected from an abandoned marine solar saltern. | a novel gram-stain positive, endospore-forming bacterium, designated sa4(t), was isolated from a soil sample collected from an abandoned marine solar saltern at wendeng, shandong province, pr china. cells were observed to be rod shaped, alginase positive, catalase positive and motile. the strain was found to grow at temperatures ranging from 15 to 40 °c (optimum 35 °c), and ph 5.0-11.0 (optimum ph 8.0) with 0-7.0 % (w/v) nacl concentration (optimum nacl 3.0 %). phylogenetic analysis based on 16s ... | 2016 | 27084709 |
| purification and characterization of a novel alkaline protease from bacillus horikoshii. | an investigation was conducted on the enhancement of production and purification of an oxidant and sds-stable alkaline protease (bhap) secreted by an alkalophilic bacillus horikoshii, which was screened from the body fluid of a unique korean polychaeta (periserrula leucophryna) living in the tidal mud flats of kwangwha island in the korean west sea. a prominent effect on bhap production was obtained by adding 2% maltose, 1% sodium citrate, 0.8% nacl, and 0.6% sodium carbonate to the culturing me ... | 2012 | 22297220 |
| bacillus zhanjiangensis sp. nov., isolated from an oyster in south china sea. | a novel gram-stain-positive, motile, catalase- and oxidase-positive, endospore-forming, aerobic, rod-shaped bacterium, designated strain jsm 099021(t), was isolated from an oyster collected from naozhou island in the south china sea. growth occurred with 0-15% (w/v) nacl (optimum 2-4%) and at ph 6.0-10.0 (optimum ph 7.5) and at 10-45°c (optimum 30-35°c). meso-diaminopimelic acid was present in the cell-wall peptidoglycan. the predominant respiratory quinone was menaquinone 7 (mk-7) and the major ... | 2010 | 20865333 |
| bacillus tianshenii sp. nov., isolated from a marine sediment sample. | a novel gram-stain-positive, motile, catalase- and oxidase-positive, aerobic, endospore-forming, peritrichous, rod-shaped bacterium, designated yim m13235(t), was isolated from a marine sediment sample collected from the south china sea. phylogenetic analysis based on 16s rrna gene sequences showed that strain yim m13235(t) belonged to the genus bacillus. the strain grew optimally at 30 °c, ph 7.0 and in the presence of 2-4% (w/v) nacl. meso-diaminopimelic acid was present in the cell-wall pepti ... | 2014 | 24614848 |
| draft whole-genome sequence of the type strain bacillus horikoshii dsm 8719. | members of the bacillus genus have been extensively studied because of their ability to produce enzymes with high biotechnological value. here, we report the draft of the whole-genome sequence of the type strain bacillus horikoshii dsm 8719, an alkali-tolerant strain. | 2016 | 27417833 |
