Psychrophilic bacteria.
Morphological characterization of small cells resulting from nutrient starvation of a psychrophilic marine vibrio
Upon starvation, Ant-300, a psychrophilic marine vibrio, was observed to decrease in size and change in shape from a rod to a coccus and regained "normal" size and shape within 48 h. Expand
Microcultural Study of Bacterial Size Changes and Microcolony and Ultramicrocolony Formation by Heterotrophic Bacteria in Seawater
With a microculture technique and time-lapse, phase-contrast photomicrography, it was possible to follow the division of individual cells and the development of microcolonies of bacteria in freshly collected marine water samples, and two types of marine heterotrophs could be described in terms of zymogenous and autochthonous bacteria.

Survival of a Psychrophilic Marine Vibrio Under Long-Term Nutrient Starvation
The data suggest that Ant-300 is capable of surviving long periods of time with little or no nutrients and is therefore well adapted for the sparse nutrient conditions of the colder portions of the open ocean. Expand
Starvation-Survival of Heterotrophs in the Marine Environment
Because microbes are the principal catalysts in the ocean, the preservation of the catalytic ability of bacteria is an important aspect of the cycles of matter. As long as the genome is preserved, itExpand
Possible strategy for the survival of marine bacteria under starvation conditions
The data indicate that Ant-300 is especially adapted for survival at low nutrient concentrations and low population densities due to a sustained increase in cell numbers that may represent a species survival mechanism for marine bacteria. Expand
Starvation-Survival Physiological Studies of a Marine Pseudomonas sp
The results indicate that the actively respiring subpopulation, rather than the viable or total cell numbers, is the most appropriate denominator for interpretation of observed activities on an individual cell basis. Expand
Effect of Growth Rate and Starvation-Survival on the Viability and Stability of a Psychrophilic Marine Bacterium
It is hypothesize that the cell population with the slowest growth rate is most closely representative of cells found in the oligotrophic marine environment, and long-term starvation corresponded to the prolongation of stage 3 starvation survival. Expand
Is H2 the Universal Energy Source for Long-Term Survival?
This paper explores a hypothesis that explains the discrepancy (time factor) between the finding of viable bacteria in ancient material and the racemization of amino acids and depurination of DNA that would have contributed to their death. Expand
