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...

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...

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...

Some physiological effects of near maximum growth temperatures on an obligately psychrophilic marine bacterium

Creator:: Geesey, G. G.
Abstract:: The heat inactivation of the psychrophilic marine bacterium, Ant-300, was investigated in terms of permeability control, glucose uptake, and respiration. Extensive leakage of 14C-cellular material occurred at 13 C, the maximum growth temperature of the organism. Protein and RNA were released from the cells in significant quantities. Inhibition of glucose...

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...

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....

Effects of salinity and temperature changes on the induction of glutamic dehydrogenase in the marine psychrophilic bacterium, Vibrio marinus MP-1

Creator:: Staley, Thomas Edwin
Abstract:: In this study the relationship between salinity and temperature changes on microbial growth, enzyme induction and substrate uptake were investigated. The obligately psychrophilic bacterium, V. marinus MP-1 was grown for 48 hours at 15 C in a glucose-ammonium medium (GAM) containing 0.4 M NaCl. Log-phase cells were harvested and shifted...

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....
