Adaptation of amoebae to four cooling tower Biocides, which included a thiocarbamate compound, tributyltin neodecanoate mixed with quaternary ammonium compounds (TBT/QAC), another QAC alone, and an isothiazolin derivative, was studied. Prev...
Microbial exopolymers provide a mechanism for bioaccumulation of contaminants [0.03%]
微生物外多聚物为污染物的生物累积提供了一种机制
G M Wolfaardt,J R Lawrence,J V Headley et al.
G M Wolfaardt et al.
Scanning confocal laser microscopy was used to directly visualize accumulation of the herbicide diclofop methyl and its breakdown products by a degradative biofilm community, cultivated in continuous-flow cell cultures. Some bacterial cells...
Thymidine and leucine incorporation in soil bacteria with different cell size [0.03%]

Thymidine and leucine incorporation into macromolecules of soil bacteria extracted by homogenization-centrifugation were measured after size-fractionation of the bacterial suspension through different sized filters (1.0, 0.8, 0.6, 0.4 μm)....
Depth distribution of microbial production and oxidation of methane in northern boreal peatlands [0.03%]
北方泥炭地微生物产甲烷和氧化甲烷的深度分布规律研究

I Sundh et al.
The depth distributions of anaerobic microbial methane production and potential aerobic microbial methane oxidation were assessed at several sites in both Sphagnum- and sedge-dominated boreal peatlands in Sweden, and compared with net metha...
Enhanced dissolution of silicate minerals by bacteria at near-neutral pH [0.03%]
中性pH下细菌对硅酸盐矿物增溶作用的增强
P Vandevivere,S A Welch,W J Ullman et al.
P Vandevivere et al.
Previous studies have shown that various microorganisms can enhance the dissolution of silicate minerals at low (8) pH. However, it was not known if they can have an effect at near-neutral pH. Almost half of 17 isolates examined in this stu...
An algD-bioluminescent reporter plasmid to monitor alginate production in biofilms [0.03%]

W H Wallace,J T Fleming,D C White et al.
W H Wallace et al.
A broad-host range algD-lux bioluminescent reporter plasmid was developed to examine the role of exopolymer production in biofilm function. The algD-lux reporter plasmid will allow rapid on-line in situ detection of environmental factors th...
Distribution of alginate genes in bacterial isolates from corroded metal surfaces [0.03%]
来自于腐蚀金属表面的细菌分离株中alg基因的分布
W H Wallace,J F Rice,D C White et al.
W H Wallace et al.
The distribution of alginate genes encoding biosynthesis of alginate was examined for bacterial isolates associated with corrosive biofilms recovered from source water, cooling lines, and reactor surfaces of a nuclear power plant. A total o...
A species-specific probe and a PCR assay for the marine bacterium, Pseudomonas stutzeri strain Zobell [0.03%]

The cloning, sequencing, and analysis of a Pseudomonas stutzeri Zobell 23S rRNA gene is described. Three variable regions were identified, and oligonucleotides homologous to portions of these regions were synthesized. The oligonucleotides w...
Jumping behavior in the oligotrich ciliates Strobilidium velox and Halteria grandinella, and its significance as a defense against rotifer predators [0.03%]
寡毛类纤毛虫Strobilidium velox和Halteria grandinella的跳跃行为及其作为轮虫捕食者防御手段的意义

J J Gilbert
The jumping behavior of Strobilidium velox and Halteria grandinella was analyzed videographically. On average, undisturbed cells of these species jumped 1.7-3.6 and 8 times per minute and spent 0.8 and 1.0% of their time jumping, respective...
