Starting the #TinyEarth approach with my #Bio111A #TeamMolecular students at @univpugetsound, we looked at their reusable water bottles and R2A plates, to teach microbial diversity, basic skills, and observation. Here is a swab on one bottle #WBB @ASMicrobiology (1/10)

@univpugetsound @ASMicrobiology Students were able to isolate various members of the water bottle microbiota as single colony isolates. @ASMicrobiology @univpugetsound (2/10)

@univpugetsound @ASMicrobiology On the way, so many interesting memebers of the water bottle microbiota were found. Here:
what I suspect is Bacillus mycoides. @ASMicrobiology @univpugetsound (3/10)

@univpugetsound @ASMicrobiology On the way, so many interesting memebers of the water bottle microbiota were found. Here:
mucoidy on the edges of groups. @ASMicrobiology @univpugetsound (4/10)

@univpugetsound @ASMicrobiology On the way, so many interesting memebers of the water bottle microbiota were found. Here:
gliding or flow of colonies. @ASMicrobiology @univpugetsound (5/10)

@univpugetsound @ASMicrobiology On the way, so many interesting memebers of the water bottle microbiota were found. Here:
"fried egg" colonial morphology. @ASMicrobiology @univpugetsound (6/10)

@univpugetsound @ASMicrobiology On the way, so many interesting memebers of the water bottle microbiota were found. Here:
pigmentation at the edges of colonies and groups. @ASMicrobiology @univpugetsound (7/10)

@univpugetsound @ASMicrobiology On the way, so many interesting members of the water bottle microbiota were found. Here:
possible siderophore production. @ASMicrobiology @univpugetsound (8/10)

@univpugetsound @ASMicrobiology On the way, so many interesting members of the water bottle microbiota were found. Here:
very thin "flares." @ASMicrobiology @univpugetsound (9/10)

@univpugetsound @ASMicrobiology On the way, so many interesting members of the water bottle microbiota were found. Here:
really odd looking phenomenon from mixed groups. @ASMicrobiology @univpugetsound (10/10)
