Plastic waste has recently been identified as one of the most serious environmental issues, affecting all life forms, natural habitats, and the economy, and is one of the most serious global environmental problems, second only to climate change. Seeking alternative environmentally sustainable options, such as biodegradation instead of conventional disposal, is critical in the face of this challenge.
However, there is currently a lack of information about the mechanisms and efficacy of plastic biodegradation. From this perspective, this study aims to illustrate the negative environmental impacts of the plastic waste. It also addresses the role of insects and gut microbiota Due to the astoundingly high rate of mortality among CF patients being attributed to respiratory failure brought on by chronic bacterial infections and subsequent airway inflammation, there has been a lot of focus on systematically analyzing CF lung airway communities.
While it is observed traditionally that Pseudomonas aeruginosa is the most threatening and persistent CF colonizer due to high antibiotic resistance, recent studies have elicited the roles of other pathogens and it has Biosolids treated sewage sludge are used as agricultural fertilizer but are frequently contaminated with macrolide antibiotics, to which resistance is rising among historically susceptible bacteria.
To determine if the land-application of macrolides carried in biosolids could promote antibiotic resistance in soil bacteria, soil plots were exposed annually to environmentally realistic or high doses of macrolides for ten years. I sequenced the bacterial 16S ribosomal DNA, metagenomic DNA, and integron gene cassettes within the treated and antibiotic-free soil to compare the compositions and diversities of the bacterial communities, antibiotic resistance genes, and mobile genetic elements.
I determined that the high dose Microbial water quality is generally monitored by culturable fecal indicator bacteria FIB , which are intended to signal human health risk due to fecal pollution. However, FIB have limited utility in most urbanized watersheds as they do not discriminate among fecal pollution sources, tend to make up a small fraction of the total microbial community, and do not inform on pollution impacts on the native ecosystem.
To move beyond these limitations, we assessed entire bacterial communities and investigated how bacterial diversity relates to traditional ecological and human health-relevant water quality indicators throughout the Milwaukee River Basin. Samples were collected from The ultra-micro size-fraction UMSF are bacteria that can pass through the 0.
Despite being ubiquitous and having high metabolic activity, UMSF remain elusive and largely uncultured. This study measures surface stream UMSF community diversity, and community response to the addition of the synthetic pharmaceutical and cosmetic carbon product This research is part of a larger study linking the soil microbiome and processes to the aboveground plant community.
Soil samples were collected from six plots under closed canopy in the Sheffield Wildlife management area in the Piedmont ecoregion of Georgia in Paulding County. Two of the plots were located in the longleaf pine savanna where restoration of longleaf pine has been in place since Samples were collected in sterile plastic tubes at the center of each plot and 10 meters above and below the center.
For each sample, soil pH and the concentration of nitrogen N , phosphorus P Myxobacteria belongs to a group of predatory bacteria that are found in various soil environments. They are exceptionally unique microbes who use their gliding motility to move towards prey microbes and consume them. They also have the remarkable ability to produce secondary metabolites that have antibacterial, antifungal, antiviral, and antitumor properties.
For this reason, they are of interest to us so that we can understand their abilities and apply them to discover their potential as a source of novel metabolites with potential therapeutic applications. Our methodology began by collecting soil samples from various sites around the country. We then standardized Soil microorganisms secrete chemicals into their surroundings, which the root system will uptake and in return release root exudates, which usually consist of low-molecular-weight organic compounds.
These root exudates behave as signaling molecules and substrates for microorganisms to recruit beneficial soil bacteria to the plant root system, which will provide the plants with immunity to foliar diseases and pathogen infection.
Studies have shown that bacteria on the root surface can protect aerial sections of the plant by promoting induced systemic resistance, a mechanism of increasing physical or chemical barriers of the plant.
Hypersaline environments are extreme habitats that can be exploited as biotechnological resources. It showed higher thermal stability and heavy metal tolerance compared to a closely related nitrilase. We also studied integrons in halophiles and hypersaline environments.
Integrons are genetic platforms in which an integron integrase IntI mediates the excision and integration of gene cassettes at specific recombination sites. In order to search for integrons in halophiles and hypersaline metagenomes, we used a PCR-based approach, in addition to different bioinformatics tools, mainly IntegronFinder.
Impact craters represent excellent astrobiological targets for planetary exploration missions to Mars. The impact of an asteroid or comet into a crystalline, H 2 O-bearing target may result in development of a hydrothermal system and increase the habitability of the substrate for the colonization of endolithic microorganisms. Zmorrod N. Amer, Hoda H. Water contamination by heavy metals has gained considerable attention globally. These inorganic pollutants can enter the aquatic environments via different routes thereby threatening biodiversity and human health.
Lead and cadmium are hazardous pollutants where their removal by traditional techniques is identified to be costly and ineffective. However, bioremediation by extremophilic microorganisms is considered to be a promising technique as they have considerable potentials to grow in harsh environmental conditions. The present study deals with the isolation of halophilic bacterial isolates from solar salterns in North Lebanon.
The isolate H1S9 was identified as Halomonas venusta H9 after showing tolerance to We conducted a study to identify the fecal metabolite profile and its proximity to the ruminal metabolism of Nelore steers based on an untargeted metabolomic approach.
Twenty-six Nelore were feedlot with same diet during d. Feces and rumen fluid were collected before and at slaughter, respectively. The metabolomics analysis indicated 49 common polar metabolites in the rumen and feces. Acetate, propionate, and butyrate were the most abundant polar metabolites in both bio-samples.
