      If we were able to sample various springs/baths in the midwest could we even culture strains like this, and then what would it take to identify them? You could compare that perhaps to total colony counts on Petri dishes.

      The Elms is a famous springwater bath locale here in Excelsior Springs, Missouri less than an hour away. Eureka Springs, Arkansas is another area nearby off the top of my head. This also has me asking general questions about other bathing scenarios that would not likely feature ancient microbes, like hot tubs, swimming pools, etc. I wonder about ALL of the variables that go into the conditions of these baths and how that might correlate to total numbers of bacteria as well as differing types. There isn't a TON of microbiology that we can do in the high school lab without help, but I do know that we are generally permitted to work with environmentally-found bacteria (like the little lab we did in the Addie unit).
  • Scientists collected samples of water, sediment and biofilm from locations within the Roman Baths complex including the King's Spring (where the waters reach around 45°C) and the Great Bath, where the temperatures are closer to 30°C.

      This means they collected from the water column itself, but also biofilms (which would be found along the edges of containments walls, etc... in addition to sediment found at the bottom of natural spring sources.
  • ...1 more annotation...
  • The samples were then analysed using cutting edge sequencing technology and traditional culturing techniques were employed to isolate bacteria with antibiotic activity.

      This obviously would require a significant bit of outside help. However, I'm still not sure we couldn't do more basic work that would be meaningful.

  • fish feed. The wastewater from soybean
  • processing can be converted into a nourishing, protein-rich food for farmed Asian sea bass, a team of scientists has discovered.
  • They worked with a local food processing company to rescue hundreds of liters of soybean wastewater, which they discovered was rich in two types of protein-accumulating microbes in particular, known as Acidipropionibacterium and Propioniciclava.
  • ...3 more annotations...
  • The sea bass that were fed the alternative microbe protein diet did have significantly lower weight to begin with, but that evened out as they grew. And, notably, the group that received the traditional feed diet had greater variability in their weight gain as they grew—whereas those fed the alternative microbe protein diet showed a more even accumulation of weight over the experiment’s course.
  • Meanwhile, the wastewater from other soybean uses goes unused—but according to the recent results, could feasibly tackle both of these sustainability challenges at once. Furthermore it’s not just soybean waste water, the researchers say: several agricultural processes create wastewater side streams that are rich in the combination of carbon, nitrogen, and phosphorus that’s needed to sustain a growing population of hungry, protein-accumulating bacteria.

    Possible more efficient fish feed to reduce waste and benefit the environment as well as the economy.

    Super interesting, and relatively simple topic. If this was looking at bacteria normally found environmentally in the kitchen, we could easily get approved. We could even culture those. The thing that makes this difficult to do at school is the fact that this is all about viruses. Detecting these in our lab would be super difficult. I'm also not sure if we could even get a culture of virally-infected cells to perform controlled studied. This one is a "maybe."

  • The study found that in animals, a high-fat diet disrupts resident gut bacteria, alters behavior and, through a complex pathway connecting the gut to the brain, influences brain chemicals in ways that fuel anxiety.
  • "To think that just a high-fat diet could alter expression of these genes in the brain is extraordinary," said Lowry. "The high-fat group essentially had the molecular signature of a high anxiety state in their brain."

      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.
