How does Burkholderia pseudomallei look on MacConkey agar?
Burkholderia pseudomallei typically appears as pale, colorless colonies on MacConkey agar because it is a non-lactose fermenter. The colonies may have a slightly rough texture and can be moist or mucoid in appearance. Unlike lactose-fermenting bacteria, B. pseudomallei does not produce the pink coloration associated with lactose fermentation on this medium.
How canacid production by glucose and lactose fermentation be differented in the same tube?
To differentiate acid production by glucose and lactose fermentation in a test tube one must look at the neck and the butt of the test tube. Different colors indicate fermentation or non-fermentation.
What media is used to look for fecal contamination of a sample?
EMB Agar
Why is agar special in microbiology?
agar is used for growing microbes as to culture microorganisms you must provide a culture medium containing carbohydrate as an energy source along with mineral ions and protein and vitamins. these nutrients are often contained in an agar medium. agar is a substance that can dissolve in hot water to form a jelly. you pour hot agar into a petri dish to set as a way to provide all the nutrients for the microbes to reproduce successfully. AGAR helps to make the media in semisolid or in jelly form which allow the microbial colonies to grow on surface by providing them better surface and we can study the colonial character of different species of microbes.
Why prevention in formation of bubbles in agar plate preparation?
Preventing the formation of bubbles during agar plate preparation is important because bubbles can create uneven spreading of bacteria or other samples on the plate surface, leading to inaccurate results. Bubbles can also trap air, interfering with the growth of microorganisms. To prevent bubbles, it's essential to pour the agar gently, allow it to cool slightly before pouring, and avoid vigorous swirling or shaking of the agar.

What does Klebsiella look like on culture plate?
Klebsiella species appear as large, mucoid colonies on culture plates, typically on MacConkey agar where they produce pink colonies due to lactose fermentation. On blood agar, they can form smooth, shiny colonies that may have a slight alpha or beta-hemolytic appearance. The colonies are often characterized by their viscous, sticky texture, which is indicative of their polysaccharide capsule.
What are the colonial features of staphylococus aureus in nutrient agar?
* Colonies are circular, 2-3 nm in diameter with a smooth shiny surface when grown on nutrient agar,milk agar or blood agar for 24 h at 37 degrees * Colonies are often pigmented,though a few strains are unpigmented Got the answers from here http://www.geocities.com/SouthBeach/Port/3008/staphyl.html

What are the alternatives for sheep blood in preparing blood agar?
I'd say it depends why you're looking for an alternative. If you are looking to avoid the use of animal based products, you could try to find human blood agar. If you just want to find something other than sheep you could look for horse, goat, or bovine based blood agar.
What is the function on bile in Eosin Methylene Blue agar?
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.
How many calories in a cup of beef stock?
look at the nutrient info thing :)
What does Shirley Temples husband look like?
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

Are bacteria growing in the semi solid agar deep motile?
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.
