When the bacterium Serratia marcescens is grown on a sterile culture medium in a Petra dish at 30C the bacterial colonies are cream colored. When this same bacterium is cultured under identical con?
When Serratia marcescens is grown at 30°C, it typically produces cream-colored colonies due to the absence of certain pigments. However, if the temperature is altered or if the growth conditions change (such as increased temperature or different nutrients), the bacterium may express different pigments, such as red or pink, leading to a change in colony color. This variation is often due to the regulation of genes responsible for pigment production, which can be influenced by environmental factors.
Where to find non pathogenic freeze dried staph bacteria with growth medium?
You can find non-pathogenic freeze-dried Staphylococcus bacteria with growth medium from scientific supply companies or online biological supply stores. These companies offer a variety of non-pathogenic bacterial strains for research and educational purposes. Make sure to follow appropriate safety protocols when working with bacteria in a lab setting.
What is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium?
Inoculation is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium.
How does autotrophic bacteria get food?
They are grown on medium that contains the nutrient that they cannot synthesize
Does Bacillus subtilis grow in MacConkey broth?
Bacillus subtilis is grown on nutrient agar or in nutrient broth. The preferred medium is M9 with glucose.

Which bacteria forms pink colonies in nutrient agar plates?
Nutrient agar is a general purpose medium supporting growth of a wide range of non-fastidious organisms. Most any bacteria will grow on it.An example of a fastidious organism is Neisseria gonorrhea, which requires blood or hemoglobin and several amino acids and vitamins in order to grow.
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. ~
Can Serratia grow on Hektoen Enteric Agar?
Yes. Serratia is a Gram negative rod from the Enterobacteriaceae family. The Hektoen Enteric agar allows the growth of Gram negative bacteria while inhibiting growth of Gram positive bacteria.
What is nutrient agar?
simply agar medium

What are the equipments used in hydroponics farming?
Hydroponics substitute a nutrient medium in place of soil. for the plants to root and grow. The nutrient medium may be either a water solution or an inert material.
What will result when 1 to 5 agar is added to nutrient broth boiled and cooled?
The agar will solidify and form a gel-like substance in the nutrient broth. This agar-nutrient mixture is used as a solid medium for growing and isolating bacteria in a laboratory setting.
What nutrient medium that has all of its chemical components identified and their precise concentrations known and reproducible would be termed?
Defined medium.
How does autotrophic bacteria get food?
They are grown on medium that contains the nutrient that they cannot synthesize
A nutrient medium that has all of its chemical components identified and their precise concentrations known and reproducible would be termed?
synthetic
