Investigating bacterial populations in styrene-degrading biofilters by 16S rDNA tag pyrosequencing
2014
Microbial biofilms are essential components in the elimination of pollutants within biofilters, yet still little is known regarding the complex relationships between microbial community structure and biodegradation function within these engineered ecosystems. To further explore this relationship, 16S rDNA tag pyrosequencing was applied to samples taken at four time points from a styrene-degrading biofilter undergoing variable operating conditions. Changes in microbial structure were observed between different stages of biofilter operation, and the level of styrene concentration was revealed to be a critical factor affecting these changes. Bacterial genera Azoarcus and Pseudomonas were among…
The development of species-specific probes for a quantitative estimation of non-cultured bacteria in groundwater samples
2012
The aim of this study was to quantify different bacteria in drinking water production wells that supply the city of Mainz (capital of Rhineland-Palatinate, Germany). Knowledge of the counts of individual microorganisms is important for the appraisal of the hygienic and sensory quality of drinking water. Specific 16S rRNA probes were designed for 14 previously identified but non-cultured bacterial species ( Ferribacterium limneticum , Hydrogenophaga sp., Methylotenera sp., Janthinobacterium sp., Pseudomonas sp., Rhizobium selenireducens , Rhodoferax sp., Nitrosomonadaceae bacterium, Thauera sp. and five strains which could not be identified to species level). With fluorescence in situ hybrid…
