Genetic relationship between Sarcina ureae and members of the genus Bacillus.
Deoxyribonucleic acid-ribonucleic acid (DNA-RNA) and DNA-DNA hybridization studies were performed to determine the degree of genetic relatedness between Sarcina ureae and several members of the genus Bacillus. DNA-RNA hybridization showed a high degree of homology between S. ureae RNA and DNA from Bacillus species having a similar guanine plus cytosine content. The DNA from other genera of the ...

متن کاملScanning electron and phase-contrast microscopy of bacterial spores.
The three-dimensional immages of free and intrasporangial spores produced by scanning electron microscopy show surface structures not visible by phase-contrast microscopy. Although fine surface detail is not elucidated by scanning electron microscopy, this technique does afford a definitive picture of the general shape of spores. Spores of Bacillus popilliae, B. lentimorbus, B. thuringiensis, B...
متن کاملThe Bio-chemical Activity of Soils
Introduction Many methods have been devised in order to obtain a picture of the relatively broad spectrum of microorganisms present in the soil (Waksman, 1932; Lohnis, 1938 ; Beijerinck, 1946 ; Winogradsky, 1949). Techniques for direct microscopic examination, including contact slide methods, were developed by a number of research workers (Rossi, 1921, 1936; Conn, 1928, 1929 ; Cholodny, 1930; K...
متن کاملFirst isolation and identification of Vibrio vulnificus (biotype 2) from cultured beluga, Huso huso in Iran
By decreasing of sturgeon stocks in the Caspian Sea, the culture of different sturgeon species especially Huso huso was increased in Iran. Under stress conditions sturgeon can easily be infected by several opportunistic pathogens. In June 2011, mortality happened in 25-28°C water temperature, in one of the most important cultured sturgeon farms in Mazandaran province in the north of Iran. The m...
