[Microbiological studies of the Wanda Lake (Antarctica)]. 1976

A E Kriss, and I N Mitskevich, and E P Rozanova, and L K Osnitskaia

The deep-water (68 m) Wanda Lake in the Antarctica is noticeable by three characteristics: a relatively high temperature in the bottom layer, elevated salinity, and the presence of H2S. Only several (less often, dozens) saprophytic microorganisms per 40 ml of water are encountered in the lake. The total number of bacteria varies from 6-10(3) to 172-10(3) cells/ml. The highest content of the total bacterial population, and saprophytes, is found in intermediate layers, 30 and 40-50 m deep, respectively. Microbial strains isolated from water and ooze belong to the genera Pseudomonas, Chromobacterium, Bacillus, and Mycobacterium. Yeast organisms were also found. Sulphate reducing bacteria were detected only at one station in ooze of the lake while thionic bacteria could not be determined at all. Photosynthetic bacteria were isolated from ooze at all four stations.

UI MeSH Term Description Entries
D009161 Mycobacterium A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts. Mycobacteria
D011549 Pseudomonas A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants. Chryseomonas,Pseudomona,Flavimonas
D002861 Chromobacterium A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria occurring in soil and water. Its organisms are generally nonpathogenic, but some species do cause infections of mammals, including humans.
D006862 Hydrogen Sulfide A flammable, poisonous gas with a characteristic odor of rotten eggs. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. (From Merck Index, 11th ed) Hydrogen Sulfide (H2(Sx)),Hydrogen Sulfide (H2S2),Hydrogen Sulfide (H2S3),Sulfide, Hydrogen
D000864 Antarctic Regions The continent lying around the South Pole and the southern waters of the Atlantic, Pacific, and Indian Oceans. It includes the Falkland Islands Dependencies. (From Webster's New Geographical Dictionary, 1988, p55) Antarctic Region,Southern Pacific Ocean,Antarctic,Antarctica
D001407 Bacillus A genus of BACILLACEAE that are spore-forming, rod-shaped cells. Most species are saprophytic soil forms with only a few species being pathogenic. Bacillus bacterium
D001419 Bacteria One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive. Eubacteria
D012965 Sodium Chloride A ubiquitous sodium salt that is commonly used to season food. Sodium Chloride, (22)Na,Sodium Chloride, (24)NaCl
D013696 Temperature The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms. Temperatures
D014867 Water A clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) Hydrogen Oxide
