Résumé :

SUMMARY Examinination of microbial diversity in environments of increasing salt concentrations indicates that certain types of dissimilatory metabolism do not occur at the highest salinities. Examples are methanogenesis for H2 + CO2 or from acetate, dissimilatory sulfate reduction with oxidation of acetate, and autotrophic nitrification. Occurrence of the different metabolic types is correlated with the free-energy change associated with the dissimilatory reactions. Life at high salt concentrations is energetically expensive. Most bacteria and also the methanogenic archaea produce high intrace

Résumé :

ABSTRACT Viridans streptococci, which include Streptococcus gordonii, are pioneer oral bacteria that initiate dental plaque formation. Sessile bacteria in a biofilm exhibit a mode of growth that is distinct from that of planktonic bacteria. Biofilm formation ofS. gordonii Challis was characterized using an in vitro biofilm formation assay on polystyrene surfaces. The same assay was used as a nonbiased method to screen isogenic mutants generated by Tn916 transposon mutagenesis for defective biofilm formation. Biofilms formed optimally when bacteria were grown in a minimal medium under anaerobic

Ammonia-oxidizing bacteria were present at 102 MPN/mL (most probable number per millilitre) in swine waste, and they were outnumbered by a factor of 105 by the heterotrophs of the indigenous flora. To study these ammonia-oxidizing bacteria we attempted to isolate them in pure culture. We succeeded in increasing the concentration of these bacteria by successive transfers to an inorganic medium, but the heterotrophs were always dominant. To overcome this problem Nitrosomonas europaea ATCC 19718 was adapted to grow in stabilized swine waste. With this adapted strain it was shown that the number o

AbstractSulfate-reducing bacteria (SRB), an anaerobic bacterial group, are found in many environments like freshwater, marine sediments, agricultural soil, and oil wells where sulfate is present. SRB derives energy from electron donors such as sulfate, elemental sulfur or metals, and fermenting nitrate. It is the major bacterial group involved in the microbiologically influenced corrosion (MIC), souring, and biofouling problems in oil-gas-producing facilities as well as transporting and storage facilities. SRB utilizes sulfate ions as an electron acceptor and produce H2S, which is an agent of

Influent sulfate concentrations ranging from 500 to 3000 mg/L were applied at COD/sulfate ratios ranging from 5.0 to 1.7. Reactors R1 and R4 were operated with higher sulfate loads than those applied to R2 and R3. For the same COD/sulfate

Résumé :

Actinomycosis is a rare and slowly progressive infectious disease that can affect a variety of organ systems including the lung. It is caused by filamentous Gram-positive anaerobic bacteria of the genusActinomyces. Despite its rarity, pulmonary actinomycosis can involve lung parenchyma, bronchial structures, and chest wall. The disease can mimic lung malignancy given its nonspecific clinical and radiological presentation, thus posing a diagnostic dilemma to the attending physician. In this paper, we describe two patients with pulmonary actinomycosis mimicking bronchogenic carcinoma; the former

The dynamic modelling of metabolic networks aims to describe the temporal evolution of metabolite concentrations in cells. This area has attracted increasing attention in recent years owing to the availability of high-throughput data and the general development of systems biology as a promising approach to study living organisms. Biochemical Systems Theory (BST) provides an accurate formalism to describe biological dynamic phenomena. However, knowledge about the molecular organization level, used in these models, is not enough to explain phenomena such as the driving forces of these metabolic

Résumé :

Extremophilicity, or the capability to thrive in environmental conditions considered extreme is generally determined from the human perspective. From that point of view, organisms adapted to scarce, or even the absence of molecular oxygen, can be considered as one of the extremophiles, i.e., anaerobes. In this chapter, various aspects of anaerobic microorganisms are addressed, including their different taxa, their phylogenetic distribution, and the environments from where they have been isolated. Since prokaryotic taxonomy is a dynamic process, here we have emphasized the organisms that are validly placed in taxa and have cultured representatives. In this section, Archaea and Bacteria - the two domains are separately discussed. Similar separation is also maintained while discussing mechanisms of adaptation, as far as possible. Since these two domains share certain properties, the subsequent sections are not separated between these two domains.

Résumé :

Dental caries remains the single most important oral condition treated by the dental profession on a daily basis. From a public health perspective, the prevention of caries is still therefore a major challenge. As outlined in Chapter 4 , before effective prevention can be delivered the cause of the condition needs to be fully understood. In addition, the disease process should be clear. This chapter will review the evidence on the aetiology of dental caries and present an overview of preventive measures that can be adopted at an individual clinical level, as well as community wide. Dental caries occurs because of demineralization of enamel and dentine structure by organic acids formed by oral bacteria present in dental plaque through the anaerobic metabolism of dietary sugars. The caries process is influenced by the susceptibility of the tooth surface, the bacterial profile, the quantity and quality of saliva, and the presence of fluoride which promotes remineralization and inhibits the demineralization of the tooth structure. Caries is a dynamic process involving alternating periods of demineralization and remineralization. However, the majority of lesions in permanent teeth advance relatively slowly, with an average lesion taking at least 3 years to progress through enamel to dentine (Mejare et al. 1998). In populations with low DMF/dmf levels, the majority of carious lesions are confined to the occlusal surfaces of the molar teeth. At higher DMF/dmf levels, smooth surfaces may also be affected by caries (Sheiham and Sabbah 2010). Many different terms have been used to name and classify sugars. This has caused a degree of confusion amongst both the general public and health professionals. In recognition of this, an expert UK government committee—Committee on Medical Aspects of Food Policy (COMA)—has recommended a revised naming system, which has now become the standard classification of sugars in the UK (Department of Health 1989). The COMA classification is based upon where the sugar molecules are located within the food or drink structure. Intrinsic sugars are found inside the cell structure of certain unprocessed foodstuffs, the most important being whole fruits and vegetables (containing mainly fructose, glucose, and sucrose).

Ammonia waste removal in recirculating aquaculture systems is typically accomplished via the action of nitrifying bacteria in specially designed biofilters that oxidize ammonia to produce nitrate. In the majority of these systems nitrate is discharged to the environment through frequent water exchanges. As environmental considerations have made it necessary to eliminate nitrate release, new strategies for nitrate consumption are being developed. In the funding period we showed that ammonia removal from wastewater could take place by an anaerobic ammonia oxidation process carried out by bacteri

Résumé :

At the beginning of this project, it was clear that R. albus adhered tightly to cellulose and its efficient degradation of this polysaccharide was dependent on micromolar concentrations of phenylacetic acid (PAA) and phenylpropionic acid (PPA). The objectives for our research were: i) to identify how many different kinds of cellulose binding proteins are produced by Ruminococcus albus; ii) to isolate and clone the genes encoding some of these proteins from the same bacterium; iii) to determine where these various proteins were located and; iv) quantify the relative importance of these proteins

Résumé :

Symbiotic bacteria have been shown to influence host reproduction and defense against biotic and abiotic stressors, and this relates to possible development of a symbiont-based control strategy. This project was based on the hypothesis that symbionts have a significant impact on Culicoides fitness and vector competence for animal viruses. The original objectives in our proposal were: 1. Molecular identification and localization of the newly-discovered symbiotic bacteria within C. imicola and C. schultzei in Israel and C. sonorensis in California. 2. Determination of the prevalence of symbiotic
