Marine bacterioplankton abundances and distributions

Creator:: Morris, Robert M.
Abstract:: Microorganisms play key roles in ocean biogeochemistry. However, several predominant groups of uncultured bacterioplankton thought to contribute to important biogeochemical processes in the oceans are known primarily from gene cloning studies. Although these studies have greatly expanded our view of microbial diversity in the oceans, they are not quantitative and...

Some physiological bases for survival of a marine bacterium during nutrient starvation

Creator:: Kurath, Gael
Abstract:: The physiological responses of populations of a marine Pseudomonas sp. to nutrient starvation were observed for a period of 40 days. During the first 25 days of starvation the viability of the population decreased by 99.9 percent, but thereafter the cultures maintained approximately 5 x 10⁵ viable cells per ml...

Starvation-survi[v]al studies on a marine Vibrio sp. and other selected marine bacteria

Creator:: Amy, Penny Susan
Abstract:: The starvation-survival patterns of 16 freshly isolated open ocean bacteria and in a psychrophilic Vibrio sp., Ant-300, were determined. These isolates displayed three survival patterns as determined by viable cell count. These were (a) a rapid increase followed by a decrease to a constant value (pattern of Ant-300 and 7...

Phylogenetic characterization of the epibiotic bacteria associated with the hydrothermal vent polychaete Alvinella pompejana

Creator:: Haddad, Michael Alexander
Abstract:: Symbiotic relationships of bacteria with higher organisms are commonly observed in nature; however, the functional role of these relationships is only rarely understood. This is particularly evident in epibiotic bacterial associations in the marine environment where the bacteria are often a diverse ensemble of microorganisms, thus complicating the identification of...

Proteomic analyses of marine bacteria

Creator:: Sowell, Sarah M.
Abstract:: Proteins are the metabolic machines of the cell and as such, the study of proteins could illuminate the dominant biological activities that are occurring within cells and reveal how an organism interacts with its environment. Here, we used proteomic techniques to study the abundant marine bacterium SAR11 both as an...

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...

Development and application of genomic DNA based methods for the identification and characterization of marine bacterioplankton

Creator:: Lanoil, Brian D.
Abstract:: A series of experiments was performed to determine the feasibility of genomic DNA-based methods for ecological and physiological studies of dominant bacteria from complex natural systems. Two approaches, bacterial chromosomal painting (BCP) and environmental genomics (EG), were evaluated for the potential to identify and enumerate specific bacterial groups in situ...
