Plastic polymers are present in most aspects of routine daily life. Their increasing leakage into the environment poses a threat to environmental, animal, and human health. These often resistant microbial degradation predicted remain for tens hundreds years. Fungi have been shown degrade complex considered good candidates bioremediation (biological pollutant reduction) plastics. Therefore, we screened 18 selected fungal strains their ability polyurethane (PU), polyethylene (PE), tire rubber. As proxy plastic polymer mineralization, quantified O2 consumption CO2 production an enclosed biodegradation system providing as sole carbon source. In contrast studies demonstrated that tested fungi attach to, colonize different without any pretreatment plastics absence sugars, which were suggested essential priming process. Functional groups identified by Fourier-transform infrared spectroscopy (FTIR), changes morphology seen light scanning electron microscopy (SEM) used indicators adaptation growth on PU substrate. Thereby, SEM analysis revealed new morphological structures deformation cell wall several when colonizing utilizing this growth. Strains Fusarium, Penicillium, Botryotinia cinerea EN41, Trichoderma high potential PU, rubber, PE. Growing over 90 % was consumed <14 days with 300–500 ppm generated parallel. Our study highlights some efficiently polymers, largely dependent type.

Toxigenic Vibrio cholerae can cycle between environmental plastic waste and floodwater: Implications for environmental management of cholera

Journal of Hazardous Materials, Год журнала: 2023, Номер 461, С. 132492 - 132492

Globally, there has been a significant rise in cholera cases and deaths, with an increase the number of low- middle-income countries (LMICs) reporting outbreaks. In parallel, plastic pollution LMICs is increasing, become major constituent urban dump sites. The surfaces environmental can provide habitat for complex microbial biofilm communities; this so-called 'plastisphere' also include human pathogens. Under conditions simulating peri-urban waste pile, we determine whether toxigenic Vibrio cholerae (O1 classical; O1 El Tor; O139) colonise persist on following simulated flooding event. Toxigenic V. colonized persisted organic at least 14 days before subsequent transfer to either fresh or brackish floodwater, where they further concentrations sufficient cause infection. Taken together, study suggests that plastics environment act as reservoirs cholerae, whilst floodwaters demonstrates potential wider dissemination cholera. Further understanding how diseases interact will be central combating infection, educating communities, diminishing public health risk environment.

Plastisphere Microbiomes Respiring Persistent Organohalide Pollutants

Environmental Science & Technology, Год журнала: 2024, Номер 58(33), С. 14740 - 14752

Plastics are invading nearly all ecosystems on earth, acting as emerging repositories for toxic organic pollutants and thereby imposing substantial threats to ecological integrity. The colonization of plastics by microorganisms, forming the plastisphere, has garnered attention due its potential influence biogeochemical cycles. However, capability plastisphere microorganisms attenuate organohalide remains be evaluated. This study revealed that collected from coastal ecosystems, harbors unique microbiomes, while natural accumulation may favor proliferation organohalide-respiring bacteria (OHRB). Laboratory tests further elucidated high microbiota reductively dehalogenate a variety pollutants. Notably, over 70% tested completely debrominated tetrabromobisphenol A (TBBPA) polybrominated diphenyl ethers (PBDEs) nonhalogenated products, whereas polychlorinated biphenyls (PCBs) were converted lower congeners under anaerobic conditions.

Enduring pathogenicity of African strains of Salmonella on plastics and glass in simulated peri-urban environmental waste piles

In low- and middle-income countries, plastic has become a major constituent of landfills urban dump sites. Environmental pollution can also provide novel surface for the formation microbial biofilm, which often includes pathogenic bacteria viruses. Here, under conditions simulating peri-urban waste pile typical an African informal settlement, we aimed to determine if Salmonella spp. retain their virulence following prolonged period desiccation on surfaces environmental glass. We show that clinically (and environmentally) relevant strains including S. Enteritidis, Typhimurium Typhi persist glass at least 28-days temperature (which increases with depth pile) is key determinant this survival. All three retained pathogenicity (determined by using Galleria mellonella model infection) recovery from plastisphere indicating plastics in environment act as reservoirs human pathogens could facilitate persistence extended periods time. Pathogens colonising therefore pose heightened public health risk, particularly areas where people are frequently exposed pollution.

Abstract Microplastics (plastic particles <5 mm) permeate aquatic and terrestrial ecosystems constitute a hazard to animal life. Although much research has been conducted on the effects of microplastics marine benthic organisms, less consideration given insects, especially those adapted urban environments. Here, we provide perspective potential consequences exposure within typical larval habitat mosquito biology. Mosquitoes represent an ideal organism in which explore biological not least because their importance as infectious disease vector. Drawing evidence from other organisms knowledge life cycle, summarise some more plausible impacts including physiological, ecotoxicological immunological responses. We conclude that although there remains little experimental demonstrating any adverse effect biology or pathogen transmission, significant gaps remain, is now need quantify microplastic pollution could have such important
