Hi, not sure if this is the right sub, but my highschool is selling those microscope for a fairly good price I think (150$ CAD), and I would like to know what are your opinions on this model or this company. They are dated back to 1981... is that bad ? My interest are in observation of bacteria, small eucaryotes and (very specific) water bear + physarum polycephalum. Here are the specs: Head: Monocular Eyepiece: Periplan 10x/18 Turret: Quintuple Objectives: EF 4x, 10x, 40x, 100× (OIL) Plate: XY mechanics with flexion clamps Condenser: Adjustable focal length condenser, N.A. 0.9 Lighting: Hal ..read more

Hello I am in a microbiology class and I am trying to identify a species of bacteria from multiple tests. I have narrowed it down to Planococcus citreus or kocurli. My unknown has shown to grow in 10% nacl content and was shown to not grow in 25% nacl content. In Bergey’s manual citreus grows at 15% and kocurli does not grow in 15% nacl content. Does anyone know which it could be or should I just do a coin flip? Also I cannot run a 15% nacl content test since the lab was setup to only use 0%,5%,15%, and 25%. Thanks for any help. submitted by /u/bhalojbs [visit reddit] [comments ..read more

Never really thought about it since I’ve always done the o/n method but recently have seen people dissolving 1 colony from a stock plate in some media and directly using that in the micro plate submitted by /u/New-Depth-4562 [visit reddit] [comments ..read more

I took microbiology in Fall ‘19 and have forgotten everything. Any extremely easy to learn materials out there, preferably free online sources? submitted by /u/DragQueen98 [visit reddit] [comments ..read more

So I recently received 2 offers from 2 different agencies to work in their diagnostic/assay development depts. One works with plant pathogens while the other deals with human/zoonotic viruses. I’ve worked with zoonotic pathogens before but in this lab, I will be learning new techniques unlike in the plant pathogen lab. The pros about the plant pathogen lab is that I don’t have to relocate and I will be exposed to working with plant pathogens. Which should I choose? And for those who have worked with both, how different are they in terms of handling and analyzing them? submitted by /u/Accompl ..read more

I am not that great when it comes to trying to identify fungi but I thought I'd share the photo here on what I think some of these colonies might be. So, what I think I am seeing and according to the morphology are: On the top right it looks like it might be penicillium since it's a common contaminant found in air. As for the brown colonie one on the left it looks like rhizopus (I compared morphologies from papers on air contaminats) but I can't figure out the rest. Thank you for reading my post in advance! submitted by /u/aSprinkle0fJ0y [visit reddit] [comments ..read more

Hi Thank you for considering my question. I realize most questions on here are by microbiologists so I hope you don't mind my post. I had some clothing and other items that I took from a nursing home in plastic storage tub and (I would not have taken them if I knew that the clothes would require bleach cleaning or not be safe) Now I wonder do I have to have to disinfect plastic tubs that I carried all the clothes in. If so, is there another alternative that is just as good as bleach like oxiclean or vinegar or listerine. Because bleach can make quite a mess and ruin a lot of stuff. submitted ..read more
