| 摘要 |
A growth plate or Petri plate and a method for detection and identification of microorganisms by specific or non-specific staining of colonies or microcolonies is described. Analytical substances (chromogenic or fluorogenic substrates, biochemical dyes, dyes indicators of pH, antibiotics and other biological active substances) are applied to the lower surface of a nutrient agar layer. The substances diffuse in the agar, reach cells and react with them. Because colonies or microcolonies are not removed from the media, they retain their shape, color, size and other useful characteristics for analytical purposes.
