What is the best way to identify a microorganism that’s been discovered under a microscope, is there a database of microorganisms that is readily accessible for reference?
The best way would be to compare the known characteristics of the microorganism in question to resources that are available for identifying microorganisms. There are several that exist, and I've written a list of them

1. [wdcm](https://www.wdcm.org)   

2. [NIH microbial Genomes](https://www.ncbi.nlm.nih.gov/genome/microbes)  

3. [CDC MicrobeNet](cdc.gov/microbenet/index.html)  

4. [FDA Microbial Identification Databases](https://www.fda.gov/science-research/licensing-and-collaboration-opportunities/microbial-identification-databases)
Thanks, I'll take a look at those!
You're welcome! Is there anything else I can help you with at the moment?
where can i find more information about microorganisms in general
