13. Development and application of monoclonal antibodies for in situ detection of indigenous bacterial strains in aquatic ecosystems.
Strain-specific monoclonal antibodies (MAbs) were developed for three different bacterial isolates obtained from a freshwater environment (Lake Plusssee) in the spring of 1990. The three isolates, which were identified by molecular methods, were as follows: Cytophaga johnsonae PX62, Comamonas acidovorans PX54, and Aeromonas hydrophila PU7718. These strains r

14. Development and field application of a quantitative method for examining natural assemblages of protists with oligonucleotide probes.
A fluorescent in situ hybridization method that uses rRNA-targeted oligonucleotide probes for counting protists in cultures and environmental water samples is described. Filtration, hybridization, and enumeration of fixed cells with biotinylated eukaryote-specific probes and fluorescein isothiocyanate-conjugated avidin were performed directly on 0.4-microns-

15. Dynamics of Bacterial Community Composition and Activity during a Mesocosm Diatom Bloom
Bacterial community composition, enzymatic activities, and carbon dynamics were examined during diatom blooms in four 200-liter laboratory seawater mesocosms. The objective was to determine whether the dramatic shifts in growth rates and ectoenzyme activities, which are commonly observed during the course of phytoplankton blooms and their subsequent demise,
