One of the best ways of studying bacteria is to grow them on a petri dish, but only a tiny percentage of bacterial species will grow on them. The other 98% of them simply refuse to.

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 12 дней назад

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.

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.

Making hundreds of Petri dishes also helped to create... believe it or not, an iconic punk rock song. A biomed student tried speeding up the process by putting multiple dishes in the oven at once, but they cross contaminated and ruined each other. "You cant keep them together, you gotta keep them separated...." he remarked. This became the basis for the song, "Come out and Play" by the Offspring, and rocketed the band to stardom in the mid 90s -- And yes, Dexter Holland is the lead singer of a 90s grunge/punk band AND A microbiology grad.

@ooooneeee 3 дня назад

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.

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.

If you can't study the organism you can still use inductive reasoning to figure things out. Lets say you can't study something that lives in a hot place, is that place simply hot or are there other things about it that lead to it growing there? Then you can go on to the experiment phase after finding a list of potential variables, if that doesn't work, what if it is a combination of things?
