Cells of an obligately psychrophilic marine bacterium, Vibrio
marinus, strain MP-1, were grown at 4 C and 15 C and studied for
possible physiological differences. No differences were noted in
sugar fermentation or temperature-shift growth studies; in both cases
adequate nutrients were available. Some differences were noted in
viability retention and manometric studies; adequate nutrients were
not available. Fifteen C cells were more heat stable than 4 C cells.
Fifteen C cells also utilized glucose at a higher rate than 4 C cells.
These differences were attributed to differences in intra-cellular organization.
The results indicated that in order to correlate laboratory
results with in situ conditions, marine microorganisms should
be studied when grown at the temperature of their natural habitat and
without an abundance of nutrients. / Graduation date: 1966
