The phycobilin chromoproteins, phycocyanin and phycoerythrin of red algae, because of their stability and water-solubility, have been studied physico-chemically by many investigators. They have been shown to have definite molecular weight, characteristic isoelectric points, mobility, diffusion and adsorption properties (Svedberg and Lewis, 1928 ; Svedberg and Katsurai, 1929 ; Svedberg and Eriksson, 1932 ; Tiselius, 1930, 1937; Swingle and Tiselius, 1951). Their behavior as accessory pigments in photosynthesis is also well established (Haxo and Blinks, 1950; French and Young, 1952 ; Blinks, 1954a, 19.541, ; Yocum and Blinks, 1954). A comparative study of the chromatographically separated phycobilins of red and blue-green algae has recently revealed the occurrence of individual ...
INTERACTION OF SALINITY AND TEMPERATURE ON NET PROTEIN SYNTHESIS AND VIABILITY OF VIBRIO MARINUS1~2 Mary F. Cooper and Richard Y. MO&a
Departments of Microbiology and Oceanography,
The relationship of temperature and salinity to protein synthesis was determined for cells of Vibrio marinus. The critical temperature of the lesion in protein synthesis increased with increasing salinity of the growth medium. Protein synthesis was significantly inhibited at 22C at a salinity of 25%,, but not at a salinity of 35%, until the cells were incubated for 20 min at 24C. The thermal lesion did not involve precursor accumulation mechanisms rather than protein synthesis at salinities between 25 and 35%0. At 40%0, the uptake of extracellular proline by whole cells was inhibited at 24C and preceded the inhibition of precursor into protein. Total RNA synthesis continued for 50 min at 22C in growth media at salinities between 15 and 35% but at 40% decreased after 20 min of cell ...
