Culturing microbes on nutrient plate and testing for different kind of microbes on specific environment areas. This inoculated nutrient plate that was left for a period of 14 days showed the present of a few different kind of fungus species. It’s common to think that the human palm contains more... Read More
microbes in the environment: there are about 4 to 5 different colonies of bacteria which is growing in agar plate; sample from library toilet seat. (front view) Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More
Most Escherichia coli (E.coli) strains are harmless.But some, like enterohemorrhagic E. coli (EHEC), are a hazard to human health and life. Read More

Serratia marcescens/Escherichia coli mix grown on TSA for 48 hrs. Serratia marcescens grows red due to prodigiosin and Escherichia coli grows opaque white. Read More
Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.
Ba... Read More
Microbes are everywhere; they live in us and on us. They can't be seen with our naked eyes, thus we tent to neglect that they're there or even existed. Some microbes are harmful and some are not. However, we must learn to avoid contaminating sterile media and materials with these microbes. In th... Read More
Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More

The American Academy of Microbiology has just released a new report, "Microbe-Powered Jobs: How Microbiologists Can Help Build the Bioeconomy," and along with it, an infographic, that summarizes the main points of the report. The full report can be found here: http://bit.ly/1lk346I, and a link t... Read More
Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More

Close up view of the edges of an unknown bacteria swabbed form the bottom of a shoe, possible Bacillus, on TSA exhibiting spreading and rhizoid growth. The pigment is opaque white-beige with a mucoid surface towards the center of the colony and a matte surface towards the edges. Note: transmit... Read More
On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More
