MacConkey-Eosin Methylene Blue Dipslide

Product Description

MacConkey-Eosin Methylene Blue Dipslide

MacConkey Agar is both selective and differential. It is used to differentiate between Gram negative bacteria while inhibiting the growth of most Gram positive bacteria. The medium also differentiates between lactose-fermenting coliforms (Lac (+)) and lactose non-fermenters (Lac (-)), which include potential pathogens.

Eosin Methylene Blue Agar is a differential (and slightly selective) medium for the isolation, cultivation and differentiate of Gram-negative enteric microorganisms (bacilli). Gram-positive bacteria are inhibited. E. coli will turn a green metallic sheen on Eosin Methylene Blue. EMB Agar is moderately inhibitory. Some staphylococci, streptococci and yeast may grow. They will appear as small, pinpoint colonies. Not all strains of E. coli produce a green metallic sheen. The presence of the green metallic sheen is not diagnostic for E. coli.

BioPaddlesLite iTunes App

The BioPaddlesLite App is a free app that helps you presumptively identify bacteria and mold colonies growing on your dipslide. By selecting the agar you used and the microhabitat you tested, the app will narrow down results from over 80 standard images. Compare your dipslide growth to the images for a presumptive identification, or use the grid for counting colonies. A more robust version is available for $5.99. The full BioPaddles app includes a library of over 250 standard images, as well as a camera function and reporting feature.
