The outbreak of the coronavirus disease 2019 (COVID-19) pandemic has sparked significant concerns regarding the significance of bioaerosols . Assessing air quality and identifying microbial pollution is crucial for estimating health risks and establishing air quality control standards. This research aimed to comprehensively investigate the microbial composition of the air at selected sites in Nigeria, focusing on the presence of potential pathogenic organisms. Over a duration of six months, from October 2019 to March 2020, samples were collected using settle plates employing the open-plate method. Standard Petri dishes containing culture media were exposed to the air for 10 to 15 minutes, facilitating the collection of settled biological particles. The designated locations included two interstate travel motor parks and two marketplaces situated in Ede and Osogbo, Osun State, Nigeria. The isolates underwent preliminary identification tests, followed by further identification of bacterial isolates using molecular techniques were employed including DNA amplification of the 16S rDNA gene using polymerase chain reaction (PCR), agarose gel electrophoresis of PCR amplicons, Sanger sequencing of bacterial 16S rDNA gene, and subsequent phylogenetic and evolutionary analysis using MEGA X. The results revealed the presence of diverse microorganisms, including pathogenic species, highlighting the importance of monitoring air quality for public health. This study contributes to the understanding of microbial pollution in the air and provides valuable insights for air quality management strategies.

Degradation of rice husks by fungi species isolated from old rice husk dumps at Abakaliki rice mill was carried out. Standard microbiological techniques were used in isolating and identifying the fungi species from the old rice husk dumps. The isolated fungi species were used to screen for their ability to degrade fresh rice husks by their ability to produce reducing sugars. The identified fungi isolates were then used to degrade fresh rice husks for five days. Also, the cellulase activities of the fungal species that degraded the rice husks were assessed for their ability to produce clear zones on carboxylmethylcellulose (CMC) agar. Results showed that ten species of fungi were isolated, out of which five were able to produce reducing sugars and were identified as Aspergilus flavus, Aspergillus niger, Aspergillus fumigatus, Rhizopus microsporus and Mucor pusillus. The result revealed that Mucor pusillus degraded the rice husks more by producing the highest reducing sugar value of 123.342 mg/l followed by Aspergilus flavus (116.551mg/l), Aspergillus fumigatus (96.731mg/l), Rhizopus microsporus (94.225mg/l) and Aspergillus niger (93.153mg/l). The highest reducing sugar production occurred on the 3rd and 4th days of degradation. With respect to cellulase activity, Mucor pusillus had the highest cellulase activity by producing the widest clear zone of 40.00mm on CMC agar while Aspergillus niger had the least cellulase activity by producing the smallest clear zone of 24.0mm in CMC agar. Therefore, the production of reducing sugars by these organisms showed that they can degrade rice husks.
