The Role of Reactive Oxygen Species in Plant Response to Radiation - PMC - 0 views

  • ROS (Reactive oxygen species) are reactive oxidants in plant cells, including hydrogen peroxide (H2O2), superoxide anions (O2•−) and hydroxide anion radicals (·OH), which may stimulate the antioxidant system of plants and act as signaling molecules to regulate downstream reactions.

Biodegradation of polyethylene by the marine fungus Parengyodontium album - ScienceDirect - 1 views

  • UV light

      If we were to use X or Gamma rays, would that speed up the process?
  • Graphical abstract
    • emmarrogers
       
      Why does it need the 9 day incubation period? Could we lower that

      So, could we just do this with a plastic bottle?

  • Other important plastic types afloat in the sea are polypropylene (PP) and to a lesser degree polystyrene (PS) and polyethylene terephthalate (PET).

      Does/ Could this fungi degrade these as well
  • Zalerion maritimum (Paço et al., 2017), Alternaria alternata FB1 (Gao et al., 2022) and Rhodotorula mucilaginosa (Vaksmaa et al., 2023a), while Cladosporium halotolerans 6UPA1 was shown to degrade PUR (Zhang et al., 2022).

    Strange.... when I go to this article, I can see your highlights, but I cannot see your comments. Usually, when I can see those, I can comment back right there as opposed to saving it myself. Grrrr...

    Super interesting topic (I saw this one last week). The work with isotopes they did here is well beyond feasibility for us, but that doesn't mean there isn't something here that could be done. You'd have to work through the set up of marine environments (tanks) and acquisition of these fungal strains. I'm betting the one they recently recovered from biofilm on plastic trash in the ocean would be super difficult to get our hands on, but they do mention several others that have previously been found to degrade plastics. perhaps those are more easily obtained. (?) Degredation fo plastic by microbes is EXACTLY what the cheater-guy did in lasy year's winning ISEF project, but like this article says, most of this work has been done with bacteria, not eukaryotic organisms like fungi. I also thing the area of biofilms is super interesting. The analysis (beyond weighing the plastic pre/post) is rather instrumental and that might be difficult depending upon our ability to find someone to help us analyze instrumentally. I like the idea, but feasibility is unknown at the moment. You might want to keep reading down this area. It is certainly interesting and important. Keep an eye on feasibility as you go forward.
