Abstract

The quality of indoor air in various buildings is crucial for maintaining the health and well-being of individuals. Exposure to airborne microorganisms can have detrimental effects on respiratory health. This study aimed to evaluate the microbiological quality of indoor air in selected primary schools in Aliero, Nigeria. Three primary schools were randomly chosen, air samples were collected using settle plates. Petri dishes containing different culture media were exposed twice daily (morning and noon). The number of organisms per cubic meter of air (CFU/m³) was recorded, and standard microbiological methods were used to identify bacterial and fungal isolates. The study revealed a wide range of bacterial and fungal contamination in classroom environments. Bacterial loads ranged from 543-165 CFU/m³, while fungal loads ranged from 146- 32 CFU/m³. Four bacterial species and five fungal genera were identified. The bacteria included Bacillus spp, Proteus spp, Staphylococcus aureus, and Micrococcus spp, while the fungal genera isolated included Aspergillus spp, Mucor spp, Fusarium spp, Penicillium spp, and Rhizopus spp. The most prevalent bacteria were Bacillus spp (34.38%) and Micrococcus spp (28.13%), while the most frequently isolated fungi were Fusarium spp (36.36%) and Penicillium spp (33.33%). The finding of this study has shed light on the indoor air quality of selected primary schools in Aliero. The present study also revealed the microbial diversity as well as the frequency of occurrence of various isolates. Measures such as improved ventilation, stringent cleaning protocols, and regular monitoring to ensure a healthier indoor environment for both students and staff.

Abstract

The environment is described as the situations or factors that encircle an individual organism or a collection of organisms. Environmental sustainability refers to the responsible and balanced management of natural resources and ecosystems to meet the needs of the present without compromising the ability of future generations to meet their own needs. Microorganisms play a critical and multifaceted role in promoting environmental sustainability by participating in various ecological processes and functions. This paper explores the roles of microbes in maintaining environmental sustainability. Microbes, encompassing bacteria, archaea, fungi, protists, and viruses, exhibit remarkable functional diversity across diverse habitats, allowing them to contribute to key environmental challenges. The challenges facing environmental sustainability, include climate change, biodiversity loss, resource depletion, pollution, deforestation, and lack of public awareness on environmental issues. Microbes contribute significantly to addressing these challenges through nutrient cycling, bioremediation, waste management, renewable energy production, climate change mitigation, ecosystem health maintenance, and enhancing agriculture and food security. The capabilities of microbes provide promising avenues for creating a more sustainable future. By elucidating the contributions of microbes to environmental sustainability, this paper underscores their pivotal role in shaping resilient and balanced ecosystems for present and future generations. As we strive for a more sustainable future, harnessing the potential of these tiny yet powerful creatures can significantly contribute to achieving a harmonious coexistence between humanity and the natural world. Further research is needed to investigate ways to engineer and optimize microbial processes for enhanced nutrient cycling, bioremediation, and waste management.
