Cultivation of Bacterium pneumosintes in the collodion sac dialysate of a tissue medium produces an antigen suitable for serological tests. Injection of dialysate cultures of Bacterium pneumosintes into rabbits results in the production of antibodies demonstrable by agglutination, precipitation, complement fixation, and phagocytic reactions. Four strains of Bacterium pneumosintes, three from th...

1. Twelve bacterial isolates that grow with trimethylamine as sole source of carbon and energy were obtained in pure culture. All the isolates grow on methylamine, dimethylamine and trimethylamine. One isolate, bacterium 4B6, grows only on these methylamines whereas another isolate, bacterium C2A1, also grows on methanol but neither grows on methane; these two organisms are obligate methylotrop...

Phototrophic consortia represent valuable model systems for the study of signal transduction and coevolution between different bacteria. The phototrophic consortium "Chlorochromatium aggregatum" consists of a colorless central rod-shaped bacterium surrounded by about 20 green-pigmented epibionts. Although the epibiont was identified as a member of the green sulfur bacteria, and recently isolate...

background and objectives: microbial spoilage of juices and industries related with alicyclobacillus are considerable international issues. this spore-forming bacterium causes changes in juices odor and taste. the isolation and identification of alicyclobacillus contamination in juice producing and packaging industries has an essential role in the prevention and control of this type of spoilage...

contagious equine metritis (cem) is a venereal transmissible and non-systemic disease of horses caused by a gram negative, bacillus or cocco-bacillus and non-motile bacterium, taylorella equigenitalis which can lead a transient infertility in mares. identification of this bacterium is based on microaerophilic culture, but weakness of this bacterium in growth compared with secondary and symbioti...

the aim of this paper was to assess the effect of catechol (ch), as a peroxidase inhibitor, and 8-hydroxyquinoline citrate (hqc), as a bacterial inhibitor, on keeping the quality of gerbera jamesonii cv. hongyan cut flowers, known to be limited by vascular occlusion. blockage in the stem xylem vessels of cut gerbera was studied using light and scanning electron microscope. the results showed th...

Insertion of lux genes, encoding for bioluminescence in naturally bioluminescent marine bacteria, into the genome of Pseudomonas fluorescens resulted in a bioluminescent strain of this terrestrial bacterium. The lux-marked bacterium was used to toxicity test the chlorobenzene series. By correlating chlorobenzenes 50% effective concentration (EC50) values against physiochemical parameters, the p...
