Abstract:

Leptothrix are long bacteria of rare occurrence; although these bacteria have been implicated in causing vaginal symptoms identical to candidiasis, studies on prevalence and effect on overall vaginal health are lacking. In this study, we evaluated data of women referred to a private clinic for treating vulvovaginal symptoms (n = 1847) and reassessed data of our previous and ongoing studies (n = 1773). The overall rate of leptothrix was 2.8% (102/3620), and the mean age of affected women was 38.8 ± 10.65 years (range 18−76). The majority of the women with leptothrix had normal vaginal flora (63

Abstract:

The provided study involves investigating chemical interactions in Leptothrix biomaterial through infrared spectroscopy. The analysis explores variations in chemical relationships based on the nature of chemical bonds and biomaterial coordinates. The primary chemical bonds identified in the biomaterial are associated with Fe-O vibrations and resonances of [OH] functional groups. Additionally, the study presents model representations detailing the formation mechanism of water molecules within the Leptothrix matrix.

A Gram-negative, rod-shaped, motile, non-pigmented, facultative aerobe that grew optimally at pH 6.5 and 30 °C (strain PM1T) was isolated for its ability to completely degrade the gasoline additive methyl tert-butyl ether. Analysis of the 16S rRNA gene sequence indicated that this bacterium was a member of the class Betaproteobacteria in the Sphaerotilus–Leptothrix group. The 16S rRNA gene sequence identity to other genera in this group, Leptothrix, Aquabacterium, Roseateles, Sphaerotilus, Ideonella and Rubrivivax, ranged from 93 to 96 %.

Im Zeitraum vom Juni 1984 bis zum Juni 1985 wurde das Wasser der Wiehltalsperre/Oberbergisches Land chemisch und biologisch analysiert. Dabei ergaben sich wichtige Aspekte bezüglich des Manganeintrages und seiner Wirkung auf die Biozönose des Sees (Erscheinen von Leptothrix echinata). Durch mehrfache Analyse des Zulaufwassers (zuletzt im Juni 1986) ließ sich nachweisen, daß die hohe Manganfracht einiger Bäche aus hydrothermal vererzten Stellen bzw. aus Abraumhalden des Erzbergbaues im Wassereinzugsgebiet stammt.

Abstract:

This study investigated whether any possible bio-corrosion of pumps could occur when operating underground pumping stations in coastal regions. Groundwater in the stations was found to contain Leptothrix sp. (iron-oxidizing bacteria, IOB) and Desulfovibrio sp. (sulfur-reducing bacteria, SRB). Four different metal specimens were exposed to saline water media, where Leptothrix sp. or Desulfovibrio sp. were inoculated solely or together. The result showed that IOB not only provoke the corrosion of galvanized and stainless steels but also accelerate (by 5–10 times) the formation of zinc/iron preci

Abstract:

Surfaces of prokaryotic cells play a significant role in the adsorption of metals from aqueous solution and the formation of authigenic minerals (Konhauser 2006). Although most studies focus on the cell wall, it is known that many bacteria synthesise an extracellular layer of polysaccharides and proteins, including what are known as sheaths. It has been shown that the cyanobacterium <em>Calothrix</em> sp. produces as sheath which is neutrally charged at circumneutral pH values, and it was hypothesized that such a sheath might allow the cyanobacterium to survive in geothermal settings with high

Abstract:

Eusocial species show incredible variation in all aspects of social living, which has facilitated their ecological success. Investigating the mechanisms which regulate variation in social traits is an important goal for evolutionary biology, since understanding fundamental mechanisms underpinning variation can inform social evolutionary theory. In this thesis, I investigate aggressive behaviour and genome architecture as essential mechanisms in regulating variation in the polymorphic social phenotype of the multiple queened ant species L. acervorum.

The performance of the nature-inspired algorithms and the biologically inspired mechanisms in the hybrid algorithm is refle

Abstract Ennoblement of stainless steel by microbially deposited manganese oxides can cause pitting corrosion of the SS in natural waters at low chloride concentrations, leading to unexpected material failures.

We then placed the ennobled coupons in a solution of low concentration sodium chloride until pitting initiated. The pits had different morphologies than those initiated by electro

Abstract Manganese fixing bacteria are found in many inland waters. These bacteria include Gallionella, Spaerotilus, Crenothrix, Leptothrix, Clonothrix and Lieskeella.

Pitting corrosion of the stainless steels comes about by a reaction of the chlorine or hypochlorite biocide with the manganese dioxide deposit through a complex mechanism through which hydrochloric acid is generated. A proposed mechanism is given. Preventative measures are suggested including cleaning and allo
