Applications of laser scanning microscopy for analysis of aquatic microhabitats

Microsc Res Tech. 1996 Jan 1;33(1):73-86. doi: 10.1002/(SICI)1097-0029(199601)33:1<73::AID-JEMT7>3.0.CO;2-1.


Laser scanning microscopy was used 1) to analyze Mn oxide-encrusted biofilms and particles in marine Mn-oxidizing enrichment cultures, 2) to optimize fluorescence in situ hybridization protocols of 16S ribosomal RNA-targeted oligonucleotide signature probes for single bacterial cell identification in particles from a wetland, and 3) to develop a combined immunofluorescence-microautoradiography procedure for analysis of the distribution of 14C-labeled organic compounds and 14C-mineralizing bacteria in groundwater seep sediments. The results demonstrated the wide applicability and benefits of using laser scanning microscopy for analysis of complex microbial assemblages.
