Had some fun earlier with some prepared slides and my phone at the LABplus facility
Okay so this one was a sample of Acidiplasma cupricumulans (taken on x100 magnification with oil submersion) which is from the Archaea domain. It’s found in highly acidic mine drainage and is used for bio-mining. It really likes acidic environments and won’t grow in anything above pH 1.0
This slide is of a bacteria called Leptospirillium ferrooxidans (again, with x100 mag and oil most of these are) and it’s also used for bio-mining. It’s used to mine for copper and strangely uranium on commercial scale. It’s isolated from acid mine drainage, mines and mineral heaps.
Alright on this write up this sounds plain nasty. It’s name is Staphylococcus pyogens which translates to “the berry found in flexible chains that produce pus.” Essentially this is found in wound infections and can range from mild infections to life threatening ones. The examples on the sheet included impetigo and necrotising fasciitis. Nice.
Okay this one isn’t mag x100, it’s on x4 but I wanted to show the kind of structure this bacteria forms. On the slide it makes a ring of bacteria which are all interwoven. This made it a bit hard to draw in my notes to be honest.
This is the slide of Sphaerotilus natans x100. I think with these I’ve messed up with the oil as at this point the bottle was a bit leaky and it got everywhere but it still shows how they overlap and their shape really shows in these. Their name means “The spherical flock that swims” so I’m assuming the ring is a section of a spherical structure although it is hard to see any flagella or cillia on my photo to determine how they swim.
This next one is a mixed culture from cheese. to be honest I was expecting a lot more diversity on this one but there only seems to be two obvious types of organism just looking at the morphology of the cells. I’m not entirely sure on what they are so any comments would be appreciated.
This one is one that sticks in my head because it’s ‘Star Jelly’ or ‘Witch’s Jam’ which are macroscopic congregations of Nostoc punctiforme which occur after the cell’s re-hydration of its dormant state called a heterocyst.
(still on Nostoc punctiforme) its name means “the nostril-slime-like organism with pin-prick markings” The pin pricks aren’t so clear in these pictures but it’s a type of Cyanobacteria which means they photosynthesize.
I thought these were quite cool and so I’d share them. Although next time i’m taking wet wipes or something to keep my hands clean in-between setting up the oil and adjusting the microscope it got everywhere my phone is still covered in it which is probably why the pictures get gradually blurrier. Anyway I hope someone else thinks these look cool and find them generally interesting. :D
