Unknown organism, possible Bacillus spp, seen on a hand print after hand washing. TSA plate was grown at 37 C for 24 hours then left at refrigerated temps for 4 weeks. Organism was a light brown and mat. The center of the growth was smooth with rhizoid like growth on the edges which were mucoid ... Read More

Bacterial mats, golden brown in color, seen at the outer edges of a geothermal vent/geyser. Cyanobacteria grow around 163 F or lower. Yellowstone National Park.
Several species of Lichens seen on rocks in Red Rock Canyon, Las Vegas, Nevada after soaking rains. These are Crustose lichens that grow on the bare surface of the rocks are hard and etch the rocks as they grow crumbling the rock. Possible species seen (ie best guess from ID guide) are the y...

Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is one of the resulting bacterial/fungal growths (yeast): Circular yellow colony, mucoid, with a donut like appearance
Meet the Microbe Mafia: K. rhizophila, E. coli, and C. xerosis. They might seem like friendly bacteria but are always looking for opportunities to cause disease. Well ..... K. rhiz is really not that bad but peer pressure works in bacterial populations as well. When armed with C. violaceum th... Read More
After seeing living microbial mats forming stromatolites in Yellowstone in Part One, now we go back in time to the Jurassic period - hunting for microbial fossils in the desert of Utah. It's Part Two of the National Park anniversary series, live on the ASM blog! #NPS100 Read More
Bacillus mycodies seen from an environmental swab grown on TSA at 37 degrees C for 49 hrs. Characteristic swirling rhizoid growth can be see. Read More
It will be a great pleasure for me and my group if you can post on your Facebook page attached photo of Petri dishes.

Diphtheria an infection caused by Corynebacterium diphtheriae can be fatal at times, especially if it involves the respiratory tract. They multiply locally on mucous membrane, produce toxin causing necrosis of epithelial cells and ultimately form pseudomembranous coat. These pseudomembrane may ... Read More
Pictured are tow lichen's living on a wooden rail after heavy rains in the Santa Cruz hills. The branching lichen (Cladonia spp) is growing up through the flat lichen (Parmelia spp). Lichens are a fungus and algae or cyanobacteria, or both, that live and function as one organism in a symbiotic... Read More

Currently, it is well established that prokaryotes possess cytoskeleton and organelles. This image depicts how magnetic organelles, magnetosomes, are properly partitioned and segregated by a mechanism that relies on the treadmilling of a dedicated cytoskeletal structure, the actin-like MamK fila...
