Hi everyone in Lab land
We have grown some interesting greeblies on our nutrient agar plates.
Any ideas what they could be? The black mouldy ones look like fairy rings

Thanks

It's really an educated guess when you're trying to identify bacteria/mould based on colour, texture etc.....but you can tell them that the glossy round yellow ones are probably Staph aureus, the fuzzy green, white & black ones are mould/fungi.....green probably Penicillium species, black probably Aspergillus niger, white maybe Aspergillus oryzae or fumigatus.....just a stab in the dark really, but reel off the names & you'll sound super cool
I've attached some with a few other greeblies identi-guessed too

My guesses would be the same as Kiah. If I could do a gram stain I could help more!

thanks for the info and attachment Bindibadgi

i will sound impresive

any idea what the black dots that are like fairy rings are? are they just mould too?

I'd say all the black colonies are Aspergillus niger...the fairy rings & the plate covered in it. It sometimes grows in circular patterns....any idea how the double ring effect happened? Looks cute

On the topic of fungi.....I just popped out to buy some stuff for a prac, & found THIS gorgeous thing growing in a garden bed just inside the school fence....

I'm sure that should come under the heading "you know your a labbie when....."

LOL

asperilligus niger. Nice one!
Yes, I havent the time to go gram staining LOL.

The fungus is impressive.
Yes its definately a case of "you know youre a lab asst when...." hee hee.
