| [morphology and cytology of bacillus benzoevorans, a new filamentous, sheathed mesophilic species, degrading various aromatic acids and phenols]. | when cultivated on solid medium or in stationary liquid medium, most of the 11 studied strains of bacillus benzoevorans grew as unbranched, flexible, immotile filaments (or trichomes) of undefined length and 1.8 micrometer diameter. they were enclosed in a sheath giving an overall diameter of 3.6 micrometer. when cultivated in vigorously shaken liquid medium, several strains grew as separate rods (1.8 x 2.2 micrometer), did not deform the filament and contained dipicolinic acid. the cytoplasm ha ... | 1984 | 6508077 |
| [biochemical characterization of bacillus benzoevorans sp. nov., a new filamentous, sheathed mesophilic species, degrading various aromatic acids and phenols]. | the eleven strains studied were prototrophic and did not grow in media containing only 1% bacto-peptone or bacto-tryptone; they grew rapidly in media containing 0.4% yeast extract and 0.2% sodium acetate or benzoate. the maximal growth temperature ranged from 39 to 45 degrees c. six aliphatic acids, four aromatic acids and five phenols were used as sole carbon and energy sources by the 11 strains. carbohydrates and amino acids (except for glycine) were not used as carbon and energy sources. nitr ... | 1984 | 6508078 |
| bacillus siralis sp. nov., a novel species from silage with a higher order structural attribute in the 16s rrna genes. | a novel bacterial strain (171544t) was recently isolated from silage and was classified in the genus bacillus by 16s rdna sequence analysis. additional silage samples have been investigated in the present study and four organisms resembling strain 171544t were isolated. phenotypic and genotypic characterization of these bacteria showed that they constitute a new species of the genus bacillus. this taxon was positioned in the family bacillaceae on the basis of evolutionary distance trees using 16 ... | 2000 | 11155995 |
| bacillus nealsonii sp. nov., isolated from a spacecraft-assembly facility, whose spores are gamma-radiation resistant. | one of the spore-formers isolated from a spacecraft-assembly facility, belonging to the genus bacillus, is described on the basis of phenotypic characterization, 16s rdna sequence analysis and dna-dna hybridization studies. it is a gram-positive, facultatively anaerobic, rod-shaped eubacterium that produces endospores. the spores of this novel bacterial species exhibited resistance to uv, gamma-radiation, h2o2 and desiccation. the 18s rdna sequence analysis revealed a clear affiliation between t ... | 2003 | 12656168 |
| multiplex pcr screening of soil isolates for novel bacillus-related lineages. | a16s rdna multiplex pcr-based high-throughput protocol is presented to screen bacterial isolates in large amounts for the appearance of novel lineages of bacteria, especially hitherto unknown bacillus relatives. the 16s rdnas of 4224 isolates from a comprehensive cultivation campaign were screened for similarity to predominant uncultured soil bacteria. soil suspensions were plated in serial dilutions on various media. after 2, 4 and 6 weeks, colonies were collected with toothpicks and transferre ... | 2003 | 14529967 |
| biodegradation and biosorption of acid anthraquinone dye. | the acid anthraquinone dye tectilon blue (tb4r) is a major coloured component from the aqueous effluent of a carpet printing plant in northern ireland. the aerobic biodegradation of tb4r has been investigated experimentally in batch systems, using three strains of bacteria, namely, bacillus gordonae (ncimb 12553), bacillus benzeovorans (ncimb 12555) and pseudomonas putida (ncimb 9776). all three strains successfully decolourised the dye, and results were correlated using michaelis-menten kinetic ... | 2000 | 15092952 |
| development and application of a selective pcr-denaturing gradient gel electrophoresis approach to detect a recently cultivated bacillus group predominant in soil. | the worldwide presence of a hitherto-nondescribed group of predominant soil microorganisms related to bacillus benzoevorans was analyzed after development of two sets of selective primers targeting 16s rrna genes in combination with denaturing gradient gel electrophoresis (dgge). the high abundance and cultivability of at least some of these microorganisms makes them an appropriate subject for studies on their biogeographical dissemination and diversity. since cultivability can vary significantl ... | 2004 | 15466517 |
| contrasting effects of dissimilatory iron (iii) and arsenic (v) reduction on arsenic retention and transport. | reduction of arsenate as(v) and as-bearing fe (hydr)- oxides have been proposed as dominant pathways of as release within soils and aquifers. here we examine as elution from columns loaded with ferrihydrite-coated sand presorbed with as(v) or as(iii) at circumneutral ph upon fe and/or as reduction; biotic stimulated reduction is then compared to abiotic elution. columns were inoculated with shewanella putrefaciens strain cn-32 or sulfurospirillum barnesii strain ses-3, organisms capable of as (v ... | 2006 | 17144301 |
| effect of soil sample preservation, compared to the effect of other environmental variables, on bacterial and eukaryotic diversity. | archived soil samples are a valuable source for retrospective ecological studies, and their recent analysis using molecular ecological approaches has drawn significant attention within the scientific community. however, the possibility of addressing ecological questions regarding detectable microbiota in dried and extensively stored soils has not yet been fully evaluated. to achieve this, soil samples collected from two long-term grassland experiments in the united kingdom and the netherlands we ... | 2009 | 19111612 |
| characterization of intracellular palladium nanoparticles synthesized by desulfovibrio desulfuricans and bacillus benzeovorans. | early studies have focused on the synthesis of palladium nanoparticles within the periplasmic layer or on the outer membrane of desulfovibrio desulfuricans and on the s-layer protein of bacillus sphaericus. however, it has remained unclear whether the synthesis of palladium nanoparticles also takes place in the bacterial cell cytoplasm. this study reports the use of high-resolution scanning transmission electron microscopy with a high-angle annular dark field detector and energy dispersive x-ray ... | 2015 | 27004043 |
| bacillus oryzisoli sp. nov., isolated from rice rhizosphere. | the taxonomy of strain 1ds3-10t, a gram-staining-positive, endospore-forming bacterium isolated from rice rhizosphere, was investigated using a polyphasic approach. phylogenetic analysis based on 16s rrna gene sequences demonstrated that the novel strain was grouped with established members of the genus bacillus and appeared to be closely related to the type strains bacillus benzoevorans dsm 5391t (97.9 %), bacillus circulans dsm 11t (97.7 %), bacillus novalis jcm 21709t (97.3 %), bacillus soli ... | 2016 | 27265352 |
