  • Biodegradability: Examples of biodegradable products
    Biodegradation is the power that some substances have in break down in other chemical components In a short period and reintegrate on Earth, with the appropriate environmental conditions It is a concept closely related to ecology, by possessing, biodegradation, the ability to reuse substances Exist Two types of degradation Easily differentiable:
  • Study on Biodegradation of High-Density Polyethylene Plastics in a . . .
    This study investigates the biodegradation of High-Density Polyethylene (HDPE) using a mixed microbial culture in a single-stage semi-anaerobic reactor, aiming to mitigate the environmental impact of plastic waste Unlike previous research that primarily employed pure culture studies, our approach utilizes a mixed culture system, which can offer a broader range of enzymatic activities and
  • Screening of selected microbial isolates for plastic degradation: a . . .
    Sustainable biodegradation approaches are essential for mitigating plastic pollution This study aimed to isolate and screen bacterial and actinomycete strains from plastic dumping-site soil for their ability to degrade Polyethylene (PE), Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), and Polypropylene (PP)
  • ECETOC Workshop Report Highlights Advances and Challenges in . . .
    This workshop provided a timely forum for experts to address the growing importance of OECD TG 309 and to outline actionable steps for its improvement The report’s findings will inform ongoing revisions to the guideline and help ensure that future biodegradation assessments are robust, practical, and environmentally relevant
  • Biodegradable or Not? Testing That Separates the Claims from the Facts
    The goal is to measure the percentage of the material that converts into carbon dioxide, water, and biomass—natural end-products that signal successful biodegradation Some of the key tests used to determine biodegradability include: Aerobic biodegradation tests: Measure decomposition in the presence of oxygen (e g , compost environments)
  • Evaluation of the Biodegradation Potential of Phytopathogenic Fungi in . . .
    In addition, the biodegradation characteristics, microbial incidence, and amino acid content were evaluated using the Duncan test (p < 0 05) to assess the efficiency and effectiveness of the decomposers in the biodegradation process compared to the control treatment, where no new microorganisms were inoculated The Duncan test was chosen for
  • Enzymatic remediation of polyester microfibers in sewage sludge and . . .
    The assessment of biodegradation was carried out through monomer detection Different enzyme loadings (0 – 300 µg); substrate concentrations (0 –200 mg cm3) and mixing methods (shaking – rotating) were tested Up to 16 6 mg of PET per cm3 of matrix were degraded in 24 h both in buffered water and sewage sludge, with slightly worse
  • What Happens to Oil When It Is Biologically Degraded in the Ocean?
    Biological degradation, or biodegradation, is a natural process that plays a crucial role in breaking down these pollutants Essentially, biodegradation involves a series of biochemical processes carried out by microorganisms, such as bacteria and fungi, naturally present in the marine environment These microbes consume the oil components as a
  • Recent progress on biodeterioration and protection of . . . - ScienceDirect
    The 2 nd International Symposium on Biodeterioration and Protection of Cultural Heritage (Dunhuang, P R China, 2024), organized jointly by Dunhuang Academy, Lanzhou University, Guangdong Technion-Israel Institute of Technology, and International Biodegradation and Biodegradation Society, was held successfully at the renowned Mogao Grottoes on June 20–23, 2024, in Dunhuang of China
  • What is the Difference Between Biodegradation and Bioremediation?
    Biodegradation and bioremediation are related but distinct processes Here are the key differences between the two: Nature of the process: Biodegradation is a naturally occurring process that involves the breakdown of organic matter by microbes Bioremediation, on the other hand, is a human-engineered technique designed to clean up organic
