Mode of action of vitamin K on saccharomyces cerevisiae

Creator:

Rasulpuri, Muhammad Latif

Abstract:

Compounds belonging to the vitamin K family possess anti-hemorrhagic property, and are used in treating patients suffering from hypoprothrombinemia and obstructive jaundice. Some of these compounds also exhibit marked antimicrobial activity toward various microorganisms. Vitamin K₅, 4-amino-2-methyl- 1-naphthol hydrochloride, a water-soluble analog of vitamin K has been shown to possess...

Symbiotic and saprophytic characteristics of a soil population of Rhizobium leguminosarum bv. trifolii

Creator:

Yap, Kathryn H. M.

Abstract:

Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

A bacterial disease of the American shad (Alosa sapidissima)

Creator:

Rothman, Stanley

Abstract:

For the past six years a bacterial infection has been the cause of large losses of adult, spawning, American shad (Alosa sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon. There was a sizable commercial fishery for shad in these rivers and losses of fish due to this infection...

Factors affecting the antimicrobial activity of vitamin K₅

Creator:

Merrifield, Larry Stanford

Abstract:

Vitamin K₅, 4-amino-2-methyl-1-naphthol hydrochloride, a water soluble analog of vitamin K has been shown to possess an antimicrobial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preservative, and it was the purpose of this study to...

The effect of temperature and hydrostatic pressure on protein, ribonucleic acid and deoxytibo-nucleic acid synthesis by Vibrio marinus, an obligate psychrophile

Creator:

Albright, Lawrence John

Abstract:

The marine psychrophilic bacterium Vibrio marinus MP-4 possessed a maximum temperature and hydrostatic pressure of 20 C and 425 atm for growth. The effects of temperatures of 21 and 25 C and hydrostatic pressures of 200, 400, 500, and 1,000 atm on protein, RNA and DNA synthesis by V. marinus...

Temperature-salinity effects on net protein synthesis and viability of Vibrio marinus mp-1, an obligately psychrophilic marine bacterium

Creator:

Cooper, Mary Faith

Abstract:

The relationship of temperature and salinity to protein synthesis was determined for cells of Vibrio marinus, MP-1. Protein synthesis was measured by the incorporation of radioactive proline into hot trichloroacetic acid precipitable material. At all salinities protein synthesis occurred at 15°C and 20°C but not at 25°C. The critical temperature...

Abstract:

Theoretical studies and experimental results are presented for the rotational motion of molecule's in crystalline solids. The group theory is solved for molecules of any symmetry matrix isolated at a site in a crystal field of any symmetry. As the potential terrier to rotation of the molecule relative to the...

Genesis of some soils in the central western Cascades of Oregon

Creator:

Brown, R. B.

Abstract:

Soils representative of several landscape units in the H. J. Andrews Experimental Forest, Western Cascade Range, were sampled, analyzed, and tentatively classified. Genetic inferences were drawn relating soils to landscape position and other factors of soil formation. Descriptive information and nutrient capital data were provided to support ecosystem modelling efforts...
