Early evolved microbial communities characterized the initial biological invasion of Precambrian continental landscapes.
The change from natural to minimal media showed an important impact on the selection and adaptation of microbial communities, characterized by CE-SSCP profiles; yet, robust bioanodes in which some microbial species were preserved were obtained in synthetic minimal media, these being sufficient for a reproducible electrochemical functionality.
For this purpose, an experimental membrane bioreactor for sulphide oxidation was set up, and the selected microbial community was characterized by constructing 16S rRNA gene libraries and subsequent screening of clones.
To assess the impact of circumcision on the penis microbiota (i.e., the microbial community), we characterized samples from the coronal sulcus the junction between the shaft and glans of the penis before and after circumcision and evaluated the circumcision-associated changes using culture independent methods and ecological analyses.
The microbial communities were characterized to compare community structure, diversity, and function in different layers.
Microbial communities were characterized through analysis of soil samples with denaturing gradient gel electrophoresis (DGGE) and quantitative polymerase chain reaction (qPCR) for archaea and eubacteria.
Recent investigations have identified microbial communities and characterized biological activity within the springs and within permafrost sections, having direct relevance to astrobiological analogue research goals.
Microbial communities were characterized by means of Capillary Electrophoresis Single Strand Conformation Polymorphism (CE-SSCP) based on rRNA genes.
Soil samples were analysed for pH, total C, total N, KCl extractable NH4 N and NO3-N, total P and Bray-extractable P. Microbial communities were characterized by phospholipid fatty acid (PLFA) profiling, using gas chromatography.
Experiments were carried out in batch bottles at 37°C without pretreatment of the algal biomass, and the microbial communities were characterized by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) profiling of 16S rRNA gene and sequencing.
