So wait... what does this mean for high school / youtuber "science" projects that involve swiping samples from various surfaces and seeing what grows in a petri dish? Do they actually give any sort of accurate representation of how clean or dirty a surface is?

[@MinuteEarth]

HAH! That's a good question. Realistically, it's a representation of the bacteria that are available on that surface and can grow on that specific nutrient base with in a given time. They may get completely different results with another base. Though to be real, it's still a nice representation for hand-washing experiments. You'd still see less species if you wash your hands better. It's not a big problem depending on the question that the experiment posed.

[@Purrfect_Werecat]

this makes me wonder about the experiment matpat did on style theory

[@Bread78787]

@@Purrfect_Werecatthat’s exactly what I thought when watching this video

[@ooooneeee]

The surface we touch every day usually have a lot of the bacteria on it that grow on our skin. Often only the number of bacteria is counted but it would be more useful to count the number of microbiome bacteria compared with the number of pathogenic bacteria and number of bacteria that neither help nor harm us. Mind you, the skin microbiome of many people contains pathogenic bacteria like Staph aureus, though they don't harm us because the microbiome keeps their numbers low by crowding them out.

[@Tismitch]

Honestly, it is very rare for a fungi or bacterium found in the environment can infect a human. Most are doing their own thing and actually don't do very well in a human, except those that evolved with us. Swabbing surfaces mostly grows bacteria that have come from a person in the first place (ignoring other microbes here), mostly because we put certain nutrients in the agar and set the incubators to 37°c to more closely simulate a human host. While it is far from accurate to show the sheer amount and variety of microbes on a surface, it at least shows that not washing your hands can lead to culturing poop bacteria from swabbing your phone. It is more relevant and memorable to the average person that way. Also, clean vs dirty is weirdly subjective. I'd not even be touching a desk I know is covered in a pathogen like E. Coli (without washing hands well before eating) but will down some yoghurt teeming with Lactobacillus!

4:30 I think you should explain what you mean here a bit more clearly. "Electric wires" are made from copper whether they be in the traces of a PCB or board-to-board cabling. The surface finish of connectors are gold to prevent tarnishing. Neither copper nor gold are toxic. Copper plays an important biological function and gold is frequently used as a hypoallergenic because it is very stable in the body. I believe you are referring to the indium tin oxide (ITO) capactive touchscreens that are used in virtually all modern touchscreens as indium is known to cause some health problems in workers exposed to it. That said, capacitive touchscreens require much more than electric wires to function... Hence the use of ITO.

The funny thing is humans used agar agar to cook sweet gels before it was used to grow microorganisms. The Japanese isolated it from algae and pioneered using it like gelatin. Fanny Hesse was married to a German microbiologist who she assisted in his lab and came up with the idea to use it as a growth medium because she used it in the kitchen and recognized that it would be perfect for use as growth media! It does not melt at the common incubation temperature of 37°C (gelatin does) and is not eaten by the bacteria like starch. The gello consistency enables lab workers to isolate different bacteria from one another by streaking if a sample contains multiple species.

Agar is a delicacy in seaside Asian cultures. The name literally comes from its name in Malay, but you may also recognise it as kanten 寒天 in Japanese. You can buy your own agar from a bakery supply store, though it won't be as pure as what is used in the lab. LB broth, the most common growth media used together with agar (agar is never used alone because it has no nutritional value) would be the one that gives the taste of a petri dish, but will likely just be a bit salty with some yeast taste (think Vegemite or Bovril) since that is what LB broth is made of.
