Bacterial diversity in Adirondack mountain lakes as revealed by 16S rRNA gene sequences.
Bacterial communities of seven lakes in the Adirondack Mountains of New York State were characterized by amplification and sequencing of 16S ribosomal DNA. Analysis of over 100 partial sequencesExpand

Microbial community structure and biogeochemistry of Miocene subsurface sediments: implications for long‐term microbial survival
Thirty closely spaced cores were obtained from Miocene‐aged fluvial, lacustrine and palaeosol subsurface sediments ranging in depth from 173 to 197 m at a site in south‐central Washington toExpand

Use of a simplified cell blot technique and 16S rRNA-directed probes for identification of common environmental isolates.
A simple technique in which rRNA-targeted oligodeoxynucleotide probes are used to identify bacteria immobilized on membranes is described. By using colony lifts, bacteria are directly transferredExpand

Identification of a common cyanobacterial symbiont associated with Azolla spp. through molecular and morphological characterization of free-living and symbiotic cyanobacteria.
Symbiotically associated cyanobacteria from Azolla mexicana and Azolla pinnata were isolated and cultured in a free-living state. Morphological analyses revealed differences between the free-livingExpand

Immunocytochemical localization of nitrogenase in bacteria symbiotically associated with Azolla spp.
In situ immunogold labeling and transmission electron microscopy were used to detect nitrogenase in bacteria (bactobionts) symbiotically associated with leaf cavities of Azolla caroliniana and AzollaExpand

Occurrence and ultrastructural characterization of bacteria in association with and isolated from Azolla caroliniana.
The occurrence and ultrastructure of bacteria in leaf cavities of symbiotic Azolla caroliniana were examined by transmission electron microscopy. Bacteria were observed in all leaf cavities of AzollaExpand

Ultrastructural characterization of eubacteria residing within leaf cavities of symbiotic and cyanobiont-freeAzolla mexicana
The occurrence and ultrastructure of eubacteria within leaf cavities of symbiotic and cyanobiont-freeAzolla mexicana were examined with transmission electron microscopy. Bacteria were observed in allExpand

Development and Utilization of Genetic Probes for Studying Zebra Mussel Veligers
A key issue in the management of zebra mussel populations is early, rapid, and accurate detection of the planktonic forms of the mussel veligers. In this study, an alternative technology toExpand
