Although it has proved difficult to develop immunological methods that will detect a sufficiently broad spectrum of yeast and mould species, molecular biology-based methods have been successfully commercialised and automated for food industry applications. Healthcare settings and environmental spores, Healthcare settings and hospitals must also maintain very low fungal counts, as patients typically have weakened immune systems. PMC Molds are multicellular fungi that reproduce by the formation of spores (single cells that can grow 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.

Indoor fungal levels in residential homes were inversely proportional to residents' returns, as frequent door and window opening created a positive environmental balance, reducing humidity and improving air circulation.20 An important retrospective study then analyzed indoor fungi levels in 1012 dwellings using airborne samples and compared them to different country guidelines.21 The number of colonies per cubic meter of air was positively correlated with asthma and rhinitis, and specific fungi species such as Aspergillus versicolor and Cladosporium spp. We examine fungal threshold levels in both outdoor and indoor settings, encompassing residential homes, libraries, buildings, workplaces, and hospitals.

By providing a clear and detailed description of the method, the aim is to facilitate the replication and extension of this study and encourage further investigation into this important topic. In 1977, a study defined pathogenic thresholds of 3,000 spores/m for Cladosporium and 100 spores/m for Alternaria.6 Subsequent research from India reported elevated levels of these threshold limits in specific months- May and June for Alternaria and December for Cladosporium spores- based on one-year analytical data.1 An aerobiological monitoring study from Central and Western Europe associated 300 spores/m of Alternaria with serious health problems.7 Research from Greece indicated that 50 spores/m of Alternaria and 400 spores/m of Cladosporium spores were found to exacerbate allergic rhinitis symptoms in sensitized individuals.
