Fungal contaminant on TSA grown at refrigerated temperatures for 1 month. Colonies appeared rhizoid throughout with a fluffy appearance. Read More
Different view of TSA plate with fungal contaminant, presumably from the air, after 1 month at refrigerated temperatures. White center spore formation can be seen with white hypae on the edges. Spore formation can be see forming towards the edges. Read More
Unknown fungal contaminant on TSA after growth at refrigerated temperatures for 1 month. White hypae can be seen at the edges with green spore formation starting in the center. Read More
Klebsiella pneumoniae grown on blood agar for 48 hrs at 37 degree's C. Read More
Serratia marcescens can form brilliant red colonies on LB agar due to the synthesis of the secondary metabolite prodigiosin. In the Microbiology teaching lab, we had students create pigment mutants of S. marcescens and these lovely shades of pink and white were collected for analysis. Read More
These are two harmless lab strains of E. coli. One can ferment the sugar lactose into acidic byproducts and the other cannot. MacConkey media contains an indicator dye that turns from red to yellow when the pH is raised. The four pink streaks were drawn with a culture of the lactose fermenter (t... Read More
Growth Inhibition of Streptococcus pyogenes by Bacitracin. Streptococcus pyogenes is sensitive to bacitracin and will not grow around the antibiotic-containing disc. The other beta hemolytic streptococci are not sensitive to bacitracin. Isolated of Beatrice Rogolino M.Sc - photo Francesco d'Aleo... Read More
Inside the filters of the aquariums harboring hundreds of species of molds and other microorganisms. In this photo we took a some part of the fungi who live into filters. The fungi are important microorganisms for health of aquarium. Read More

Some holiday fun from last winter composed of different collected plate contaminants. Based on colony morphology and wet mounts, these bacteria are likely to be: Staphylococcus sp. (white), Serratia marcescens (dark orange), and Micrococcus luteus (creamy yellow). The design was incubated for 5-... Read More
A group of fungi growing on the surface of stagnant black tea left open to the environment. I've found this leads to beautiful morphologies when I try it. Read More

In a Microbiology Lab,we are always delighted to find something new.Specially when their is contaminant on the media which is kept for discarding.Microbiology is a subject in which you are never at rest. Read More
Image of antifungal activity of Lactobacillus isolates against Geotrichum spp., Aspergillus spp. and Penicillum spp.. While Reviewing my results I could see an interesting thing that it resembles as like aliens face. Read More
This filamentous fungus was isolated from soil of a petroleum hydrocarbon polluted ship breaking yard. It can degrade some linear petroleum hydrocarbons, like kerosene, diesel and octane. Read More
Growth of the gram negative bacteria Vibrio fischeri expressing bioluminescence as a result of the symbiotic interaction with Euprymna scolopes. You can see the plate without shining and glowing in the dark. The Form is the mascot of the University of Puerto Rico at Rio Piedras campus. Read More
This is a Tease Prep stain of the Fungal Rhizopus with Lactophenol Blue. It is seen under a microscopy at total magnification of 1000x. As shown there are pseudohyphae with conidia formed around the cells. It was the first tease prep stain that clearly shows the artistry of the fungal structure.... Read More
Salmonella is a zoonotic foodborne pathogen and a public health concern. It has been estimated that this pathogen causes ~1.2 million illnesses, ~20,000 hospitalizations, and ~400 deaths in the US annually (Scallan et al., 2011). Salmonella has ~2,600 serotypes (serovars) and numerous hosts and ... Read More
