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...
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...
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...
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...
The transport response of four marine psychrophilic bacteria
to a variety of substrates was determined and related to environmental
conditions. Studies on pressure and temperature effects on glutamic
acid transport and utilization indicated that high pressures and
low temperatures inhibit glutamate transport, while permitting glutamate
respiration. Similar results were obtained...
The microbial composition of Pacific oysters (Crassostrea gigas)
subjected to UV-treated seawater was determined by quantitative and qualitative means. A total of 2,779 microorganisms were identified from seawater and oysters during a 72 hour sampling period employing a computer assisted replica-plating technique. UV treatment effectively eliminated coliforms and Pseudomonas Type...
