E. coli was grown on MacConkey Agar (MAC) at 37 degrees for 24 hour. MAC is a Selective and Differential media used to inhibit G+ growth and some G- bacteria as well as identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation produces pi... Read More

Sulfonated and non-sulfonated cyanines exhibit very similar fluorescent properties. Non-sulfonated cyanines must be dissolved in organic co-solvent (DMF or DMSO) prior to use, and added to a solution of target molecule in aqueous buffers. Recommended volume of co-solvent should be 10% for Cy3, C... 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
Behold some of the bacteria that grew when an 8-year-old boy who had been playing outside pressed his hand onto a large Petri dish. The photo has been getting lots of buzz after his mom posted it on MicrobeWorld last week.
