    Protein Synthesis in Cell-Free Preparations of Crithidia fasciculata (1968)
    Oxford, UK : Blackwell Publishing Ltd

    Notizen: SYNOPSIS. Cell-free preparations from Crithidia jasciculata carried out protein synthesis as measured by 14C-leucine uptake (optimum ∼ 10 mM Mg++) and poly U-directed 14C-phenylalanine uptake (optimum ∼ 16 mM Mg++). Characteristics of the system and sucrose density-gradient patterns of ribosomes were investigated. The charging and transfer reactions—the 2 main steps in protein synthesis—were inhibited by stilbamidine, hydroxystilbamidine, pentamidine, quinapyramine (Antrycide), and suramin.

    Fine Structure of the Cell Surface and Golgi Apparatus of Ochromonas (1978)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 25 (1978), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: SYNOPSIS. Ochromonas danica has an unusually flexible cell surface capable of producing projections of varying sizes and shapes: large projections, 340–360 nm long, and small projections, 50–110 nm long. These projections have been demonstrated by transmission and scanning electron microscopy; some of them may break off into the medium and be the source of extracellular membranes and vesicles reported in the cell-free O. danica growth medium. Ruthenium red stained the acid mucopolysaccharide layer just outside the cell surface as well as small blebs at the cell surface.The Golgi complex of O. danica, Ochromonas malhamensis, Ochromonas sociabilis and Ochromonas sp. produced small coated vesicles which may move toward and fuse with the plasma membrane. The role of the several vesicles is unknown but possible functions are discussed.

    Phototaxis and Thermotaxis in Some Species of Amphistegina (Foraminifera) (1974)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 21 (1974), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Positive phototaxis was demonstrated in specimens of Amphistegina radiata within the range of photonic fluxes of 1011 to 1015 photons × cm-2× sec-1. No response was found at lower intensities. Amphistegina radiata has a Dartnall nomogram-shaped action spectrum with a peak at ∼500 nm. In addition, A. radiata and A. madagascariensis, which had been maintained at 18 C, moved toward higher temperatures in a horizontal temperature gradient in total darkness. Amphistegina radiata and A. madagascariensis did not move at temperatures ≤ 12 C and ≤ 16 C respectively. An equal number of specimens moved toward the higher and lower temperatures in the gradient when A. radiata was placed at ∼29 C and A. madagascariensis at ∼22 C. The roles of light and temperature in the distribution of the genus Amphistegina in nature are discussed.

    Cyclidium citrullus Cohn, a Ciliate from the Hot Springs of Tiberias (Israel) (1972)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 19 (1972), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: A thermophilic ciliate Cyclidium citrullus (Hymenostomatida) was collected from Tiberias hot springs at temperatures of 50–58 C. In the laboratory, the ciliates were grown in monoxenic cultures with Escherichia coli in a mineral medium of 3% (w/v) salts similar in composition to that of the hot springs. C. citrullus tolerates a wide range of temperatures, 18–47 C. The optimal temperature is ∼44 C. The ciliates could tolerate direct transfer to salt concentrations of 0.2–7.0% (hot springs composition). No cysts or other dormant forms have been observed. A description of the ciliate based on living and stained specimens is given. The taxonomy and ecology of Cyclidium from hot springs is discussed.
