Abstract:
... Relationships between hosts and host-associated microbial communities are complex, intimate, and associated with a wide variety of health and disease states. For these reasons, these relationships have raised many difficult questions and claims about microbiome causation. While philosophers and scientists alike have pondered the challenges of causal inference and offered postulates and rules, ther ...

The changes in the nitrogen removal performance and microbial communities between flocs-granules hybrid and granule-based systems were studied in this experiment. With a reduction in the flocs ratio (35% → 10%), the nitrogen rem ...

Abstract:
... Marker gene amplicon sequencing is often preferred over whole genome sequencing for microbial community characterization, due to its lower cost while still enabling assessment of uncultivable organisms. This technique involves many experimental steps, each of which can be a source of errors and bias. We present an up‐to‐date overview of the whole experimental pipeline, from sampling to sequencing ...
