Prokaryotic extremophiles were the first representatives of life on Earth and they are responsible for the genesis of geological structures during the evolution and creation of all currently known ecosystems. Flexibility of the genome probably allowed life to adapt to a wide spectrum of extreme environments. As a result, modern prokaryotic diversity formed(More)
A detection system that utilizes a primer mixture in a nested polymerase chain reaction for detecting Mycoplasma contaminants in cell cultures is described. Primers were designed to amplify the spacer regions between the 16S and 23S ribosomal RNA genes of Mycoplasma and Acholeplasma. This detection system was able to detect 20-180 colony forming units per(More)
In this work, corrections are made to the descriptions of the species Anoxybacillus pushchinoensis corrig. and the genus ANOXYBACILLUS: Experiments to determine the relationship of A. pushchinoensis K1(T) to oxygen showed that it was capable of aerobic growth, but preferred to grow anaerobically. During aerobic growth, the redox indicator resazurin was(More)
Captured Diversity in a Culture Collection: Case Study of the Geographic and Habitat Distributions of Environmental Isolates Held at the American Type Culture Collection Melissa Merrill Floyd, Jane Tang, Matthew Kane, and David Emerson* Bacteriology Program, American Type Culture Collection, Manassas, Virginia; Environmental Science and Policy Program,(More)
Species-specific polymerase chain reaction (PCR) primers have been designed to identify the causative agent of columnaris disease, Flavobacterium columnare. The 16S rRNA gene sequences of F. columnare (eight sequences representing the different genotypes of the species) and related species (18 sequences) were aligned and compared to choose specific regions(More)
A novel, psychrotolerant, facultative anaerobe, strain FTR1T, was isolated from Pleistocene ice from the permafrost tunnel in Fox, Alaska. Gram-positive, motile, rod-shaped cells were observed with sizes 0.6-0.7 x 0.9-1.5 microm. Growth occurred within the pH range 6.5-9.5 with optimum growth at pH 7.3-7.5. The temperature range for growth of the novel(More)
A novel, alkaliphilic, obligately anaerobic bacterium, strain SCAT, was isolated from mud sediments of a soda lake in California, USA. The rod-shaped cells were motile, Gram-positive, formed spores and were 0.4-0.5x2.5-5.0 microm in size. Growth occurred within the pH range 6.7-10.0 and was optimal at pH 8.5. The temperature range for growth was 10-45(More)
A novel, extremely psychrotolerant, facultative anaerobe, strain PmagG1(T), was isolated from guano of Magellanic penguins (Spheniscus magellanicus) collected in Chilean Patagonia. Gram-variable, motile cocci with a diameter of 1.3-2.0 mum were observed singularly or in pairs, short chains and irregular conglomerates. Growth occurred within the pH range(More)
Osmoprotectants are low molecular weight, hydrophilic, nontoxic molecules that assist a cell under osmotic stress to stabilize its concentration of internal solutes. These properties are similar to compounds used as cryoprotectants for the preservation of prokaryotic cells during freezing. This study tested the ability of a common compatible solute, glycine(More)
A novel, obligately anaerobic, psychrotolerant bacterium, designated strain PPP2T, was isolated from guano of the Magellanic penguin (Spheniscus magellanicus) in Chilean Patagonia. Cells were Gram-stain-positive, spore-forming, straight rods (0.7-0.8x3.0-5.0 microm) that were motile by means of peritrichous flagella. Growth was observed at pH 6.7-9.7(More)
