Occupants and surface types drive microbial dynamics in controlled indoor environments.

ABSTRACT:

Background

Indoor microbial communities play a critical role in influencing indoor environmental quality and human health and are shaped by occupant activity, surface characteristics, and environmental conditions. While previous studies have examined these factors individually, systematic evaluations of their combined interactions, particularly involving Heating, Ventilation, and Air Conditioning (HVAC) and drainage systems, remain limited. This controlled, long-term (1.5-year) investigation assessed how human occupancy, surface moisture (dry vs. wet), aquaponics (soilless plant-aquarium systems), and environmental parameters (humidity, ventilation, and seasonal variations) influence bacterial and eukaryotic dynamics in tightly sealed residential units.
