Abstract: A plurality of petri dishes (44) or other glass or plastic containers are coated on the inside bottom surface of the containers by passing the containers through a coating or layering apparatus (18). The apparatus includes an indexing conveyor (12) to sequentially pass the open containers through a filling station where an amount of the coating material is applied while tilting the container to one side thereby distributing the material to the entire bottom surface of the container. The containers are conveyed to an aspirating station (20) to aspirate excess material while tilting the container toward the aspirating nozzle (122). Subsequent to the aspiration step, the containers are tilted in the opposite direction to distribute the material in the container. The material is then dried and the containers stacked and packaged. The coating material includes metal ions such as calcium or other divalent metal ions, in a suitable carrier that is able to bond the bottom inside surface of the container. The coating material forms a dehydrated, solidified layer bonded onto the bottom surface of the container. The coating material can be a water/agar solution or a plastic resin in an appropriate solvent containing the calcium ions.

Abstract: Una pluralidad de cajas de Petri u otros recipientes de vidrio o plástico son recubiertos en la superficie de fondo interior de los recipientes pasando los recipientes a través de un aparato de recubrimiento o estratificacion. El aparato incluye un transportador clasificador para pasar consecutivamente los recipientes abiertos a través de una estacion de llenado donde se aplica una cantidad de un material de recubrimiento mientras inclina el recipiente a un lado distribuyendo con ello el material a toda la superficie de fondo del recipiente. Los recipientes son transportados a una estacion de aspiracion para aspirar el exceso de material mientras inclina el recipiente hacia la tobera aspiradora. Después del paso de la aspiracion, los recipientes son inclinados en la direccion opuesta para distribuir el material en el recipiente. El material es después secado y los recipientes son apilados y empaquetados. El material de recubrimiento incluye iones de metal como iones de calcio u otros iones de metal divalente, en un portador adecuado que sea capaz de adherirse a la superficie de fondo interior del recipiente. El material de recubrimiento forma una capa deshidratada, solidificada adherida a la superficie de fondo del recipiente. El material de recubrimiento puede ser una solucion de agua/agar o una resina de plástico en un solvente adecuado conteniendo los iones de calcio.

Abstract: A test method and medium for quantitatively identifying and distinguishing biological materials in a test sample. A first biological material has enzym e specificity for a first chromogenic substrate, a second biological material has enzyme specificity for a second chromogenic substrate, and a third biological material has specificity for one of the substrates. The chromogen ic substrates form respective first and second colored water insoluble compound s upon reaction with specific enzymes. The first and second biological materia ls are capable of fermenting a sugar, and the third biological material does no t ferment the sugar. The test medium is adjusted to a pH conducive for color change of a pH indicator upon fermentation, resulting in the formation of a zone of a third color around the water insoluble compounds of the fermenting materials. Following incubation, the sample is examined for the presence of colonies of the first biological material, having the first color and an encircling zone of the third color; for colonies of the second material, having the second color and the colored zone; and for colonies of a third material having the first or second color, and not having the colored zone.
