Summary: Airborne microorganisms from forested areas play a role in cloud formation through ice nucleation. However, the vertical transportation of these microorganisms is not well understood. In this study, aerosols were collected at different heights over the forest during three seasons and analyzed to understand the distribution and composition of airborne microbial communities. The results showed that microbial particles had higher concentrations in the forest zone compared to the area above the canopy during summer and fall, indicating efficient vertical mixing in winter. High-throughput DNA sequencing revealed the presence of terrestrial and phyllospheric species associated with the degradation of plant litters in the airborne microbial communities.

Summary: Numerous studies have shown that arbuscular mycorrhizal fungi (AMF) can enhance plant nutrient absorption and defense against plant pathogenic microbes. A meta-analysis of 650 paired observations from 136 published papers revealed that AMF had a greater effect on promoting plant growth in the presence of pathogenic microbes, with factors such as pathogen harm level and AMF root length colonization also influencing the outcomes. These findings have implications for the potential and application of AMF in agroecosystems.

Summary: The USA is one of the top cotton-producing countries globally and cotton farming is commonly practiced in Georgia. Cotton harvesting can contribute to airborne microbial exposures, but the use of respirators or masks can help reduce this exposure. However, the OSHA Respiratory Protection Standard does not apply to agricultural workplaces, and the effectiveness of N95 respirators against airborne microorganisms and antibiotic resistance genes during cotton harvesting has not been tested. This study addressed these gaps by sampling airborne microorganisms on cotton farms and evaluating the protection provided by N95 respirators. The findings showed that cotton harvesting can release antibiotic resistance genes into the farm air, and the tested N95 respirators did not offer sufficient protection against microorganisms and antibiotic resistance genes during cotton harvesting.

Summary: This study aimed to investigate the association between agricultural exposure and sarcomas. The results found that farmers working <10 years with cattle, farmers breeding >= 50 livestock, farmers involved in animal care and building disinfection, as well as farmers in greenhouse and field-grown vegetable production, had an increased risk of developing sarcomas. Additionally, pesticide use in vineyards was positively associated with the occurrence of gastrointestinal stromal tumors. These findings suggest a potential link between agricultural exposure and the development of sarcomas.

Summary: This study investigated the potential human exposure to airborne microorganisms, including MRSA, in a pigeon exhibition in Denmark. The results showed high concentrations of fungi, bacteria, and endotoxin in the air, with concentrations up to 200 times higher than outdoor references. The bacteria found in the exhibition were mainly species found in pigeon coops, indicating that pigeons are the sources of exposure. The presence of airborne MRSA highlights the importance of considering this environment as a potential place of exchange of resistant bacteria between animals and humans.

Summary: The enzymatic processes involved in the degradation of the artificial sweetener acesulfame (ACE) in municipal wastewater treatment have been poorly understood. In this study, two bacterial taxa, an unknown Chelatococcus species and Ensifer adhaerens, were enriched from activated sludge using ACE as the carbon source, and cell-free lysates were analyzed to demonstrate enzymatically catalyzed ACE degradation. The fractionation of the lysate succeeded in separating the enzymes responsible for the initial transformation of ACE and further transformation pathway, providing evidence that the cleavage of the sulfuric ester moiety of ACE is the initial step. The analysis of the unfractionated lysate revealed proteins possibly involved in ACE transformation, including a highly abundant amidase and an ABC transporter substrate-binding protein.

Summary: Occupational exposure during waste sorting is associated with various health outcomes. This study compared the impact of work in fully automated waste sorting plants (AWSP) versus manual waste sorting plants (MWSP) on personal exposure to bioaerosols and related health effects. The results showed that workers at AWSP had lower exposure levels to inhalable dust, thoracic dust, and endotoxins compared to MWSP, but higher levels of fungal fragments, fungal spores, and actinobacterial spores. Microbial DNA exposure varied within and between types of waste sorting plants. Exposed workers also reported more common health symptoms compared to the unexposed control group.

Summary: Synthetic plastics, such as PET, are widely used but pose a major threat due to their environmental persistence. The bacterium I. sakaiensis has been discovered to solely thrive on degrading PET films and its monomers. By analyzing protein expression, it was revealed that PET and its monomers induce the MHETase and affect two major pathways: the TCA cycle and the beta-oxidation pathway. The increased expression of proteins involved in these pathways suggests their importance in the degradation process.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
