Studies on the effect of moderate temperature on Vibrio marinus

Creator:: Robison, Sarah May
Abstract:: Washed cells of Vibrio marinus MP-1 grown at 15 C (organism's optimum growth temperature) were employed in this study. These cells were exposed to heat at and above their maximal growth temperature (20 C) for one hour and tested manometrically at 15 C for their ability to take up oxygen....

Growth characteristics and metabolism of Beggiatoa

Creator:: Burton, Sheril Dale
Abstract:: The addition of catalase to culture medium increased the period of viability of Beggiatoa from one week to two months. Addition of catalase also produced a marked increase in cell yield and enzyme activity. The addition of cysteine or hydrogen sulfide to the growth medium or the use of semi-solid...

The effect of temperature and hydrostatic pressure on deamination of L-serine by Vibrio marinus an obligate psychrophile

Creator:: Albright, Lawrence John
Abstract:: Vibrio marinus MP-1 (ATCC 15381) deaminated nine of seventeen amino acids tested with L-glutamine being deaminated to the greatest and L-serine to the second greatest extent in one hour. The optimum pH for the L-serine deamination was 8.4. The response of washed cells to temperature on the deamination of L-serine...

Studies on partially purified malic dehydrogenase from the marine psychrophile, Vibrio marinus

Creator:: Langridge, Patricia
Resource Type:: Masters Thesis

General studies of temperature effects on an obligate psychrophile Vibrio marinus

Creator:: Haight, Roger Dean
Abstract:: Vibrio marinus, strain MP-1, was shown to grow from pH 6.7 to 8.5, with an optimum at 7.3. Growth was inhibited below salinity 10%₀ and above 60%₀ . The upper temperature limit of growth was 20 C, and growth was very rapid with aeration at 15 C. Heating of the...

Studies on glucose-6-phosphate dehydrogenase obtained from Vibrio marinus, an obligate marine psychrophile

Creator:: Miller, Wayne Warren
Abstract:: Four-fold partially purified glucose-6-phosphate dehydrogenase (G-6-PDH) from the obligately psychrophilic marine bacterium Vibrio marinus was effected by thermally induced leakage of the enzyme, ammonium sulfate fractionation and column chromatography on Sephadex G-200 gel. The effects of temperature, pressure, salinity, and pH were determined for the various degrees of enzyme purity....
Resource Type:: Masters Thesis

Thermal inactivation studies on some enzymes from Vibrio marinus, an obligately psychrophilic marine bacterium

Creator:: Mathemeier, Paul Fredrick
Abstract:: Some enzymes of the citric acid cycle and glycolytic pathway in cell-free extracts of Vibrio marinus MP-1 were compared for thermal lability. After one hour of moderate temperature exposure, enzymes of both pathways rapidly lost catalytic activity. For all but one enzyme, 50 percent remaining activity occurred near an averaged...

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...

Glucose uptake and catabolism in the marine psychrophilic bacterium, Vibrio marinus

Creator:: Griffiths, Robert Porter
Abstract:: The effects of various physical parameters on the binding, uptake, and catabolism of glucose in the marine psychrophilic bacterium, Vibrio marinus, were studied. It was shown that shortly after the cell was exposed to labeled glucose, the radioactive label became rapidly associated with the cell fraction. It was also shown...
