“…The main Firmicutes included Bacillus, known for their endospores that can remain dormant for years. Bacillus is a common bacterium found in transported desert dust ( 16, 42 ), and the deep marine environment ( 43 ). Some Bacillus species are known for their unique metabolites and antagonistic activity against pathogens ( 44, 45 ).…”

Microbes play essential roles in biogeochemical processes in the oceans and atmosphere. Studying the interplay between these two ecosystems can provide important insights into microbial biogeography and diversity. We simultaneously mapped the microbial diversity of airborne and marine bacterial communities across 15,000 kilometers in the Atlantic and Pacific oceans. Higher variability in microbial community composition was observed in the atmosphere than in the surface waters. In addition, a greater similarity was observed between oceans as compared to their overlaying atmosphere, and between atmospheric samples than with the ocean beneath. We detected higher coverage and relative abundance of marine bacteria in the Pacific atmosphere as compared to the Atlantic, while the dominant fraction in the Atlantic atmosphere was annotated as soil-associated bacteria. This study advances our understanding of microbial dispersion over oceans, and of their potential impact on ecology, and biogeochemistry.

“…Aerosol bacterial communities closer to the dust origin region (Beijing, China) are altered by Aeolian dust highly than their outlying analogous areas (Osaka, Japan) is showed in Figure 1C (Park et al, 2018). As the 16S ribosomal RNA gene quantity increased, bacterial diversity expanded considerably into AD samples, and the PM 10 concentration was associated positively (Yoo et al, 2019). AD samples are usually abundant with the Bacillus species (almost 23.8%) than the non-AD models (almost 13.3%).…”

“…Usually, the bioaerosols are transported freely or attached to dust particles suspended in the atmosphere (Aalismail et al, 2020). Strong seasonal winds cause Aeolian dust from arid and semiarid Mongolia and northern China (Yoo et al, 2019). East Asian countries China, Japan, and Korea are disturbed mainly by Aeolian dust and the bioaerosols by air currents through the westerly winds (Kobayashi et al, 2015;Park et al, 2018).…”

Occurrences and exposure to high levels of microbial bioaerosols such as pathogenic bacteria, fungi, fungal spores, and viruses can be linked to the deterioration of the environment and public health. This study aimed to review the results available for the unusual bioaerosol distribution scenario in the Asian regions. The amount of bioaerosol load and their environmental behavior in the atmosphere is heavily influenced by air pollution such as haze, fog, dust, and particulate matter (PM) and thus strongly affect the air quality index (AQI). Human factors such as heavy traffic, overcrowds, and biomass burning also affected the prevalence or occurrences of bioaerosols in the atmosphere. Seasonal/temporal and diurnal variation was significantly observed from these studies and in the case of South Asia, post-monsoon and winter months were incredibly concentrated with pathogenic bioaerosols. Many human infections, for example, pneumonia, tuberculosis, brucellosis, anthrax, and query fever (Q-fever), are linked to pathogenic bacterial bioaerosols. Respiratory diseases such as asthma and chronic pulmonary obstructiveness are related to fungal bioaerosols, spores, and viral infections. To facilitate the testing and monitoring appraisal of airborne bioaerosols, artificial intelligence, deep neural networks, and machine learning can be used to develop real-time PCR-based bioaerosol sensors. Moreover, mobile apps and compatible electronic gadgets can be developed for the city dwellers to real-time monitor the concentration of bioaerosols in the air they are breathing.

This study investigated the potential role of the concentration, shape, size, and polymer type of microplastics (MP), in addition to the microbial community in six coastal areas of Busan city, South Korea. The results showed that the average MP concentration was 94 ± 41 particles·m-3, and particles sized 20 μm –300 μm accounted for 67.5 ± 9.6% of the total MP abundance throughout the study sites. Further, polyethylene (PE), polypropylene (PP), and polystyrene (PS) polymers were abundant among the collected fragment- and fiber-shaped MPs, implying that highly populated and industrialized areas are major sources of MPs contamination. Moreover, the bacterial diversity and taxa-based on 16S rRNA gene sequencing was significantly different between MPs and seawater (SW) samples. Specifically, Psychrobacter, Pseudomonas, Flavobacterium, and Winogradskyella were significantly enriched in MPs compared with SW (p <0.05). Redundancy analysis revealed that nutrient concentrations, salinity, and temperature potentially contributed to shaping the microbial communities on MPs. These results indicate the dynamic and complicated interactions of MP contamination with the physiochemical and environmental factors of the surrounding area. Our findings would help in understanding of MP contamination levels in marine environments and their characteristics, as well as bacterial colonization on plastics in urban coastal areas of Busan, South Korea.
