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...

Growth rate effects during starvation-survival of a marine psychrophilic vibrio

Creator:: Moyer, Craig Lee
Abstract:: Cell populations of the marine bacterium ANT-300, from either batch culture or continuous culture with dilution rates ranging from D = 0.170 h⁻¹ (fast) to D = 0.015 h⁻¹ (slow) were monitored for 98 days under starvation. Viability (CFU), acridine orange direct counts (AODC), and optical density were measured. DNA,...

Incidence and significance of bacterial chitinase in the marine environment

Creator:: Goodrich, Thomas Dale
Abstract:: The marine vibrio ANT-500 is a typical psychrophile. The growth range of the bacterium at 35‰ S is from a maximum growth temperature of 13.5 C to a minimum growth temperature of -2.5 C or less with the optimum near 7 C. The bacterium elaborates its chitinase enzymes between the...

Ion and salinity effects on induction and function of galactose permease in an Antarctic psychrophilic marine bacterium

Creator:: Hayasaka, Steven Shin
Abstract:: A number of Antarctic marine psychrophilic bacteria were isolated having the ability to grow and accumulate ¹⁴ C-TMG only at temperatures below 20 C. It was shown that galactose rather than lactose was the primary inducer and utilizable substrate for the permease system. Further studies with a Vibrio species (Ant-12),...

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...

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 long-term nutrient starvation on a marine psychrophilic vibrio

Creator:: Novitsky, James Alan
Abstract:: Ant-300, a psychrophilic marine vibrio, was starved for periods in excess of one year. Cells starved at a high initial cell density increased in numbers from 100 to 800% of the initial number of cells during the first week. Fifty percent of the population remained viable for six weeks while...

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....
