Serratia marcescens may lack the characteristic orange-red pigmentation due to genetic mutations that affect the production of the pigment prodigiosin. Environmental factors such as temperature, pH, and nutrient availability can also influence pigmentation in S. marcescens. Additionally, the presence of other competing microorganisms or stress conditions may inhibit the production of pigments.
What else can I help you with?
If streaking for isolated colonies was done with Serratia Marcescens what is the difference between pigmentation between cells grown at 25 and 37 degrees celsius?
Serratia marcescens incubated at 37 degrees Celsius will have almost a clear pigmentation. However, when S. marcescens is incubated at 25 degrees Celsius it will produce a very distinct red color.
There is a lack of orange-red pigmentation in some of the growth on your agar slantl abeled S.marcescens. Does this necessarily indicate the presence of a contaminant?
No. The reason is, Chromogenic microorganisms may produce intracellular pigments that are responsible for the coloration of the organisms as seen in surface colonies. Other organisms produce extracellular soluble pigments that are excreted into the medium & that also produce a color. BUT........ most organisms, however, are nonchromogenic & will appear white to gray. ~jmata Microbiology 205 lab manual question. ~
Is albinism a mutation in humans?
Yes, albinism is a genetic mutation in humans that results in a lack of melanin production, leading to a lack of pigmentation in the skin, hair, and eyes.
Why the cuticle transparent?
The cuticle is transparent because it is made up of a thin, protective layer of cells that lack pigmentation or other substances that would make it opaque. This transparency allows light to pass through and reach the underlying tissue for processes like photosynthesis in plants.
What colour is an albino animal?

How are spirit bears defined scientifically?
They are albino Black Bears (They lack pigmentation)
What term is used for an animal lacking in pigmentation?
An animal lacking in pigmentation is referred to as albino. Albino animals have a genetic condition that results in a lack of melanin, the pigment that gives color to skin, fur, and eyes. This lack of pigmentation can give albino animals a white or pale appearance.
Why do some English Bulldogs have a pink nose?
This would be due to a lack of pigmentation however, this trait is highly undesirable and, in fact, a disqualifying factor in the show ring.

An antonym for chlorophyll could be "lack of pigmentation" or "colorless."
Do dogs have a birthmark?
As birthmarks are the result of anomalies in skin pigmentation or blood vessels in the skin, it is an easy presumption that anything with skin may develop 'birth marks' or be born with one or more, regardless of species. Perhaps a notable exception would be albinos; the result of a lack of skin pigmentation.
