EMB Agar
On nutrient agar, Yersinia appears as smooth, opaque colonies with a pale yellowish color. On EMB agar, colonies may show greenish metallic sheen due to lactose fermentation. On MacConkey agar, Yersinia typically forms colorless to pale pink colonies due to its inability to ferment lactose.
On an agar plate, C. difficile colonies typically appear as irregularly shaped, flat, opaque colonies with a yellow-brown or greyish color. They may also have a slightly mucus-like consistency and a distinctive horse manure-like odor. Additionally, some strains may exhibit a characteristic "ground glass" appearance.
Klebsiella bacteria are rod-shaped (bacilli) and have a characteristic polysaccharide capsule that surrounds the cell, giving a mucoid appearance on agar plates. Its colonies typically appear smooth, raised, and mucoid with a sticky consistency. Klebsiella can come in various colors, including pink, white, yellow, or cream, depending on the growth conditions and the type of media used for culture.
Agar deeps are used to see whether an organism requires oxygen to grow. If there is spreading growth only at the bottom of the tube, the organism is an obligate anaerobe (meaning it cannot tolerate oxygen). If there is growth only at the surface of the agar, the organism is an obligate aerobe (it cannot grow without oxygen). And if there is growth all along the point of innoculation, the organism is a facultative anaerobe and can survive either way.
Bacteria growing in semi-solid agar may exhibit motility, but it depends on the specific bacterial species and their motility characteristics. Some bacteria are capable of moving through the semi-solid agar using flagella or other mechanisms, while others may not exhibit motility in that environment. Observation of individual bacterial species in semi-solid agar can determine if they are motile.
Bile salts in Eosin Methylene Blue agar inhibit the growth of Gram-positive bacteria, allowing for the selective growth of Gram-negative bacteria. This helps in the detection and differentiation of organisms based on their ability to ferment lactose and produce acid.
Like an ordinary positive number.
it looks a +

The name of her first husband was John Agar and her husband from 1950 till his death in 2005 was Charles Alden Black. I hoped that helped a bunch:D
It means you like it, you look on it as a good thing or person.
A plus sign for positive and a minus sign for negative.
what does a positive pregnancy test look like from family dollar
I dont know
