Genetic relationship between Sarcina ureae and members of the genus Bacillus.

The isolation of Sarcina ureae (Beijerinck) Lohnis from sea water.

Scanning 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...

Phylogeny of the members of the genus Alburnoides in Iran using COI gene

Up to now, twelve species of the genus Alburnoides belonged to Cyprinidae have been described from Iranian inland water solely based on the morphological characteristics. The described key characters for these species have no efficiency for their discrimination, and cannot help their precise diagnosis. Therefore, this study was conducted to study the phylogenetic relationship and verification o...

The relationship between platelets and bacteria.

In an attempt to clarify conflicting reports taminated with L.acteria nd left at room as to whether blood platelets are bactetemperature for 48 hr, all organisms but ricidal, platelets were artificially conone (Sarcina) grew out of control. Howtaminated with seven different bacteria: ever, this organism was also killed in cellBacillus subtilis, Escherichia coil, Enterofree plasma. The presence ...

Novel phenylalanine dehydrogenases from Sporosarcina ureae and Bacillus sphaericus. Purification and characterization.

NAD+-dependent phenylalanine dehydrogenases were purified 1,500- and 1,600-fold, and crystallized from Sporosarcina ureae SCRC-R04 and Bacillus sphaericus SCRC-R79a, respectively. The purified enzymes were homogeneous as judged by disc gel electrophoresis. The enzyme from S. ureae has a molecular weight of 305,000, while that of B. sphaericus has a molecular weight of 340,000. Each is probably ...
