Numerous research articles on indoor air quality in healthcare settings have been published in recent decades, but separate thresholds have not yet been defined. And most recently, in 2022, research from Japan32 concluded that indoor-air fungal counts at all sampling points were less than 1000 colony forming units (CFU)/m3, which is the recommended limit for fungal contamination in indoor air. Aims: A research was undertaken to explore the possibility to use Biolog system of microbial metabolic characterization for the monitoring of yeast population evolution during alcoholic fermentation for wine production. Survey of volatile organic compounds found in indoor and outdoor air samples from Japan.

Another study investigated microorganism concentrations, aerosol black carbon, and carbon dioxide (CO2) levels in the indoor and outdoor air of two kindergartens during four seasons.22 The study found that the highest concentrations of aerobic mesophilic microorganisms in indoor air were detected in spring, with Cladosporium, Penicillium, and Aspergillus being the most common fungi. Until about 50 years ago the spoilage of food by microorganisms was regarded as a quality issue rather than a food safety concern. It is the cause of Legionnaires Disease, a severe form of pneumonia and, it is the cause of Pontiac fever, a non-pneumonic form of L. pneumophila infection. II.
