| cellular signals regulating antibiotic sensitivities of bacteria. | the effects of bacterial masses upon the drug resistance of neighboring bacteria were investigated. the experiments were performed with plastic petri dishes divided into two identical compartments. a growing mass of bacillus subtilis (signal emitter cell) in one compartment exerted enhancing effects upon the erythromycin and streptomycin resistance of bacillus carboniphilus (signal recipient) cells, sparsely seeded in the other compartment, through the plastic wall and the air. these effects of ... | 1996 | 9158728 |
| production of sound waves by bacterial cells and the response of bacterial cells to sound. | bacterial cells enhance the proliferation of neighboring cells under stress conditions by emitting a physical signal. continuous single sine sound waves produced by a speaker at frequencies of 6-10, 18-22, and 28-38 khz promoted colony formation by bacillus carboniphilus under non-permissive stress conditions of high kcl concentration and high temperature. furthermore, sound waves emitted from cells of bacillus subtilis at frequencies between 8 and 43 khz with broad peaks at approximately 8.5, 1 ... | 1998 | 12501293 |
| growth-promoting effect of carbon material upon bacterial cells propagating through a distance. | carbon material such as graphite and activated charcoal, but not diamond, causes the promotion of growth of certain bacteria under ordinarily non-permissive stress conditions over a distance of several centimeters. bacillus carboniphilus under the stress of a high kcl concentration and high temperature responded to this remote effect of carbon material with enhanced growth, and thermophile bacterium bacillus stearothermophilus responded similarly yet moderately under the stress of low temperatur ... | 1997 | 12501323 |
| bacillus arenosi sp. nov., bacillus arvi sp. nov. and bacillus humi sp. nov., isolated from soil. | a group of nine gram-positive endospore-forming bacteria was isolated from soil of the drentse a agricultural research area in the netherlands. using (gtg)5-pcr genomic fingerprinting and fatty acid analysis, the nine isolates were divided into three consistent groups. on the basis of 16s rrna gene sequence similarity of representative strains, the nine isolates were shown to belong to the genus bacillus. the first group of four isolates was most closely related to bacillus carboniphilus (95.5 % ... | 2005 | 15653863 |
| bacterial degradation and corrosion of naphtha in transporting pipeline. | five naphtha hydrocarbon-degrading bacteria including representative strains of the two classified species (serratia marcescensar1, bacillus pumilusar2, bacillus carboniphilus ar3, bacillus megaterium ar4, and bacillus cereus ar5) were identified by 16s rdna gene sequence in a naphtha-transporting pipeline. the naphtha-degrading strains were able to be involved in the corrosion process of api 5lx steel and also utilized the naphtha as the sole carbon source. the biodegradation of naphtha by the ... | 2007 | 17680305 |
| characterization of corrosive bacterial consortia isolated from petroleum-product-transporting pipelines. | microbiologically influenced corrosion is a problem commonly encountered in facilities in the oil and gas industries. the present study describes bacterial enumeration and identification in diesel and naphtha pipelines located in the northwest and southwest region in india, using traditional cultivation technique and 16s rdna gene sequencing. phylogenetic analysis of 16s rrna sequences of the isolates was carried out, and the samples obtained from the diesel and naphtha-transporting pipelines sh ... | 2010 | 19844704 |
| bacillus oceani sp. nov., a new slightly halophilic bacterium, isolated from a deep sea sediment environment. | a strictly aerobic, gram-stain positive, slightly halophilic strain, designated scsio 04524(t), was isolated from a deep sea sediment sample collected from the northern south china sea at a depth of 3415 m. the isolate slightly embedded into the medium after 72 h incubation at 30 °c. growth was found to occur on media with 0-10 % nacl but extremely weak growth occurred without supplying nacl. the predominant menaquinone was determined to be mk-7. the major cellular fatty acid identified was iso- ... | 2013 | 23934481 |
| bacillus oleivorans sp. nov., a diesel oil-degrading and solvent-tolerant bacterium. | two gram-stain-positive, diesel oil-degrading, solvent-tolerant, aerobic, endospore-forming, rod-shaped bacteria were isolated from a contaminated laboratory plate. based on 16s rrna gene sequence analysis, strains jc228(t) and jc279 were identified as belonging to the genus bacillus within the family bacillaceae of the phylum firmicutes and were found to be most closely related to bacillus carboniphilus jcm 9731(t) (98.1% 16s rrna gene sequence similarity) and shared <96.0% 16s rrna gene sequen ... | 2015 | 25667390 |
