I happen to come across some colonies (I thinks its a bacterium) on some left over yoghurt and was wondering if someone could help me to identify it.
About the colonies.
I had left some yoghurt in the fridge for some days. I noticed that the yoghurt surface has been stain... Read More

Lipid Plate/Tributyrin Agar used to test for an organisms ability to produce the exoenzyme lipase which breaks down the lipids in the agar creating a clear zone around the organism. (A) Serratia marcesens, lipid hydrolysis, indicated by a zone of clearing around the growing colony, as well as th... Read More

Each year the ASM's MicrobeLibrary Visual Collection Editorial Committee presents the Editor's Choice Award to three visual resources (one animation, one still image, and one video) published over the past year. The chosen resources exemplify the criteria for publication in the MicrobeLibrary. T... Read More
Scientists have engineered yeast cells that can “talk” to one another using a versatile plant hormone called auxin.
Typically, these simple fungal cells (Saccharomyces cerevisiae) usually do their jobs—making bread rise or converting sugar into alcohol—without having to communicate or work to... Read More
Photograph of a poster issued by the Chinese government in the late 1970s depicting the spread of hookworm to humans by the use of human feces as fertilizer. A prevention method is also illustrated - wearing shoes. These posters have been in the office of Dickson Despommier since the 1970s. Read More
Pictured is a culture of Mycobacterium tuberculosis growing colonies in the distinctive "serpentine cord" form seen in many strains of M. tuberculosis. These cords are made up of chains of cells that make chains due to a cell wall factor of MTB.
The cell wall structure of Mycobacterium is a m... Read More
Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.
This is a good news story all around. UC Berkeley engineers, Michael D'Amrosio and Matthew Bakalar (UC Berkeley Bioengineering) with medical personal from NIAID, Dr. Thomas Nutaman and his collaborators from Cameroon and France collectively took the omni-present global resource, a standard smar...

Photosynthetic microbial mats forming large conical structures up to half a meter tall have been discovered by astrobiologists in Lake Untersee, Antarctica. This research is described in an article in the May 2011 issue of the journal Geobiology.
Lake Untersee is located at 71°20'S, 13°45'E i... Read More
This fungal colony, in association with a few others, was grown on SDA and appears to be an antibiotic producer. The compounds that it's producing appear orange and red. The colony grew and began producing compounds on the agar after five days incubation at 30 degree Celsius. This plate is part ... Read More
