Gluconobacter oxydans is a gram-negative bacterium belonging to the family Acetobacteraceae. G. oxydans is an obligate aerobe, having a respiratory type of metabolism using oxygen as the terminal electron acceptor. Gluconobacter strains flourish in sugary niches e.g. ripe grapes, apples, dates, garden soil, baker's soil, honeybees, fruit, cider, beer, wine. Gluconobacter strains are non-pathoge...

Earlier reports have recorded preliminary angiocardiographic studies in pulmonary tubercubosis.’3 The purpose of this paper is to summarize the angiocardiographic experience in patients with pulmonary, hibar and mediastinab tuberculosis studied over a 14 year period. Knowledge of the status of the vascular supply to the lung affected by tuberculosis is of considerable importance, for the effici...

Infections caused by Salmonella bacteria, often through poultry products, are a serious public health issue. Because of drawbacks associated with antibiotic prophylaxis, alternative treatments are sought. Bacterial viruses (bacteriophages) may provide an effective alternative, but concerns remain with respect to bacteriophage stability and effectiveness. To this end, we assessed the stability o...

A chemostat coculture of the sulfate-reducing bacterium Desulfovibrio oxyclinae together with a facultative aerobe heterotroph tentatively identified as Marinobacter sp. strain MB was grown under anaerobic conditions and then exposed to a stepwise-increasing oxygen influx (0 to 20% O(2) in the incoming gas phase). The coculture consumed oxygen efficiently, and no residual oxygen was detected wi...

OBJECTIVES During the treatment of chronic apical periodontitis and pulp necrosis the main role is to irrigate the root canal. AIM The aim of this in vivo study was to irrigate with 0.9% NaCl (Natrium Chloride), 2.5 % NaOCl (Sodium Hypochlorite Solution, Sigma Aldrich - Germany) and 2% CHX (Chlorhexidine Digluconate Solution, Sigma Aldrich - Spain) combined with Gaseous Ozone (Prozone WH, Aus...

Growth characteristics of the insect pathogen, Bacillus popilliae Dutky, were studied by propagation in shaken flasks and in 2-liter fermentors. Maximal populations between 5 x 10(8) and 2 x 10(9) viable cells per milliliter of culture medium routinely were obtained in incubation periods of 18 to 24 hr at 30 C in a medium composed of 1.5% yeast extract, 0.6% K(2)HPO(4), and 0.2% glucose or treh...

BACKGROUND AND PURPOSE Intra-abdominal infection can be a life-threatening condition in children, and aggressive treatment is usually needed. The treatment should include surgical correction and drainage, and administration of antimicrobials that are effective against both aerobic and anaerobic microorganisms. This study investigated the microbiological characteristics of intra-abdominal infect...

High-viscosity carboxymethylcellulose (CMC) promotes gastrointestinal disorders, tissue alterations and bacterial overgrowth in pigs. The impact of CMC on intestinal absorptive and secretory physiology is not known. We hypothesised that CMC consumption alters intestinal Na-dependent glucose absorption and stimulates electrogenic chloride secretion. For testing this hypothesis, twenty-four pigle...

The roots of land plants associate with microbes, including fungal symbionts that can confer abiotic stress tolerance. Bitumen extraction following oil-sand surface mining in the Athabasca region of Alberta, Canada removes plant nutrients but leaves a petrochemical residue, making the coarse tailings (CT) hostile to both plants and microbes. We isolated an endophyte strain of the Ascomycete Tri...

Perry, Jerome J. (North Carolina State University, Raleigh), and James B. Evans. Oxidation and assimilation of carbohydrates by Micrococcus sodonensis. J. Bacteriol. 91:33-38. 1966.-Micrococcus sodonensis is a biotin-requiring strict aerobe that cannot utilize carbohydrates as sole sources of carbon and energy. However, addition of mannose, glucose, sucrose, or maltose to a medium on which the ...
