Even after this rather brutal treatment the microbial assemblage is capable of re-stabilisation despite have sustained considerable damage and dispersal among a far greater volume of sediment than is normal for the highly stratified natural assemblages.
This suggests that the more phylogenetically-related microbial assemblages detected in older CF patients may be more resistant to these antimicrobials and contribute to poorer airway function, while the more diverse pediatric microbial assemblage is more sensitive to antimicrobial perturbation and linked to improved pulmonary function.
The stabilisation of the substratum by estuarine microbial assemblages was due to the secreted EPS matrix, and both EPS concentrations (quantity) and EPS components (quality) were important.
Two different microbial assemblages were assessed.
Microbial assemblages were determined using molecular approaches (terminal restriction length polymorphism and automated ribosomal intergenic spacer analysis).
Many distinct marine ecosystems and their microbial assemblages are identified and studied, ranging from ice-swept polar seas to deep-sea hydrothermal vents.
Qualitative differences in microbial assemblages were found between faecal mounds and ambient (>10 cm apart) sediment within a single intertidal flat.
Microbial assemblages are found as biofilm on solid substrata and on plant surfaces (Gagnon et al. 2007).
Microbial assemblages were sampled from an offshore deep sub-surface petroleum reservoir 2.5 km below the ocean floor off the coast of Norway, providing conditions of high temperature and pressure, to identify new thermostable enzymes.
Thus, microbial assemblages are influenced not only by water chemistry, which varies temporally as a function of season, oceanographic conditions, tidal phase and river discharge [4], but also by transport from both the river and adjacent coastal ocean.
Nonetheless, this study demonstrates that distinct microbial assemblages are associated with CF patient age and that community composition is correlated with CF genotype and aspects of pulmonary disease in this patient population.
