You solve the puzzles by fitting all the microbes back into the Petri dish. There are over 100 different challenges with 9 levels of difficulty. Move over Rubik’s Cube. Microbes Attack! Microbial Puzzle Game For Ages 7 and up. Solve the puzzles by fitting all the microbes back in the Pe...
You have probably seen microbiologists grow microbes in petri dishes and then count colonies. That does work but only for species that grow on the food in petri dish. The majority of soil organisms won’t grow this way. Dr. Elaine Ingham from the Soil Food Web Organization promotesthe use ...

Einstein in a Petri Dish (Image credit: Zachary Copfer ) A smaller version of Copfer's Einstein portrait. Art and Science (Image credit: Zachary Copfer ) Copfer sees the same thinking behind both art and science. He says: "Picasso and Einstein were working with the same idea, looking at ...
Figure 11. In the pour plate method of cell counting, the sample is mixed in liquid warm agar (45–50 °C) poured into a sterile Petri dish and further mixed by swirling. This process is repeated for each serial dilution prepared. The resulting colonies are counted and provide an estimate...
species to enter the instrument. The samples were inserted without touching the internal surface of the jar and placed on a sterile petri dish. A blank control comprising only the glass jar and a sterile petri dish was also sampled. The experimental controls were blank coupons in two replicates...
[1], allowing for quantitative estimates of the number of viable microorganisms in bacterial samples. Soon afterwards, agar was used in research and the Petri dish was developed, paving the way for standardized bacterial observations. These tools allowed for standards for the determination of ...

Part of this deficiency is due to current methods for culturing bacterial colonies, most commonly, the petri dish. In this setting, where all different species of bac- teria are placed together, competition arises and the slower growing, less adaptive bacteria that may even be...
