It's all about light. Light has all of the colors in it and those that are not absorbed into the bacteria are reflected. It just so happens that the colors of the light spectrum that are reflected give off a pink color. Look into physics and calculus if you want to go more in depth with that one.

Why did the colonies on the MAC plate turn pink?
The colonies that grew on MAC plate took up lactose from the medium for their metabolism and released an end product that caused the pH indicator of the medium (neutral red) to turn pink. Hence the colonies appears pink in color.
What microorganism forms a pink colony on MacConkey agar?
Well, Macconkey Agar II plates have Gram Crystal Violet in them so there are a number of bacterial species that can absorb it and turn "very pink." The way to narrow it down is to identify whether it grows in chains or clusters. But other than that, it is hard to tell.
What will grow pink or red colonies on nutrient agar?
micro coccus Species
Can macConkey Agar plates test for e coil?
Yes. Colonies will be red or pink.
Why does the ecoli and pseudomonas are different on the MacConkey agar?
MacConkey's agar is a differential media used to differentiate between lactose fermenting and lactose non-fermenting bacteria. E.coli is a lactose fermenter whereas Pseudomonas is a lactose non-fermenter.MacConkey's agar contains lactose as fermentable sugar and when it is fermented the pH of the medium decreases which is registered by neutral red (a pH indicator).Lactose fermenters such as E.coli produce pink colonies whereas lactose non-fermenters such as Pseudomonas produces colorless colonies. So the colors of E.coli and Pseudomonas colonies are different on MacConkey's agar.
Does micrococcus roseus test positive for mixed acid fermentation?

What is the scientific name of tsitsirika?

Micrococcus kristinae versus micrococcus luteus?
The easiest way to differentiate them is by color. Both are pigment producing, and while M. luteus has yellow colonies, M. roseus has pink colonies. If you need a more scientifically valid way of differentiating them, try using a nitrate reduction test. M. luteus can not reduce nitrate while M. roseus can.
What animal has the scientific name phoenicopterus roseus?
The scientific name Phoenicopterus roseus refers to the greater flamingo, a species of large, colorful water bird known for its distinctive pink plumage and long S-shaped neck. They are found in various wetland habitats and are known for their specialized bill structure for filter feeding.
