Microautoradiographic study of Rhodocyclus-related polyphosphate-accumulating bacteria in full-scale enhanced biological phosphorus removal plants

Article Abstract:

The ecophysiology of uncultured Rhodocyclus-relatedpolyphosphate-accumulating organisms (PAO) present in three full-scale enhanced biological phosphorus removal (EBPR) activated sludge plants is analyzed by using microautoradiography combined with fluorescence in situ hybridization. The results indicate that Rhodocyclus-related PAO were able to denitrify and hence played a role in the denitrification occurring in full-scale EBPR plants.

Development and evaluation of genome-probing microarrays for monitoring lactic acid bacteria

Article Abstract:

The genome-probing microarray (GPM) is used to monitor the population dynamics of lactic acid bacteria (LAB) during the fermentation of kimchi, a traditional food in Korea. The results of GPM hybridization with fluorescently labeled bulk community DNA have indicated the practicality and applicability of this new quantitative tool for the estimation of cultivatable bacteria from different environments.

Determination of cyanobacterial diversity during algal blooms in Daechung Reservoir, Korea, on the basis of cpcBA intergenic spacer region analysis

Article Abstract:

The intergenic spacer (IGS) region between phycocyanin subunit genes cpcB and cpcA (cpcBA IGS) is analyzed to study the diversity and community dynamics of cyanobacteria during cyanobacterial bloom in the Daechung Reservoir, Korea. The cyanobacterial diversity derived from the cpcBA IGS analysis is compared with that determined by 16S rRNA gene PCR-denaturing gradient gel electrophoresis (DGGE).
