When lipids are added to an agar-solidified culture medium and are cultured with lipolytic bacteria, the surrounding medium becomes acidic due to the release of fatty acids. By adding a pH indicator (such as Spirit Blue which has a lavender color), it is possible to detect lipolysis by a clear area surrounding the bacterial growth. A clear area around bacterial growth indicates a positive test. In the absense of lipolysis, the medium retains its lavender color and is a negative reaction.
What else can I help you with?
If you use glucose broth medium without a pH indicator how can you determine whether a particular bacterium fermented glucose?
You can determine whether a bacterium fermented glucose by performing a series of biochemical tests. Some common tests include measuring gas production, pH changes, and presence of fermentation products like acids or alcohols. Additionally, you can use specific reagents or methods tailored for detecting fermentation byproducts to confirm the presence of fermentation.
What is the difference between bacteria and bacterium?
bacteria is plural and bacterium is singular
Is bacterium plural?
bacteria is, unless you were to use the word "The" in front (the bacteria are) Answer The bacterium is ...., the bacteria are..... Bacteria is the plural form, bacterium is the singluar.
What is marine bacterium?
a bacterium that lives underwater
How will you determine whether a box is more or less dense?
less
How could you determine whether a bacterium fermented the following carbohydratesmannitolsorbitol adonitol or arabinose?
To determine if a bacterium ferments mannitol, sorbitol, adonitol, or arabinose, you can perform biochemical tests such as the phenol red broth test or the methyl red test. In phenol red broth, a color change to yellow indicates acid production from fermentation. The methyl red test detects mixed acid fermentation by the production of stable acid end-products. By observing these reactions in the presence of the specific carbohydrates, you can determine if the bacterium ferments them.
How can you determine whether a bacteriu fermented the following carbohydrates mannitol sorbitol adonitol or arabinose?
You can determine if a bacterium fermented a specific carbohydrate by observing changes in pH, gas production, or by using selective media containing indicators that change color when fermentation occurs. These tests can help identify which carbohydrates are utilized by the bacterium based on the metabolic byproducts produced during fermentation. Additionally, genetic tests or biochemical assays can be used to analyze the enzymes produced by the bacterium to determine its ability to ferment specific carbohydrates.
How can you determine whether the zone of inhibition is due to death of a bacterium or to inhibition of growth?
To determine whether the zone of inhibition is due to death of a bacterium or inhibition of growth, you can perform a viability assay by transferring a sample from the zone to a growth medium and observing if growth occurs. If growth does not occur, it suggests bactericidal activity. Additionally, conducting time-kill studies can help differentiate between bacteriostatic and bactericidal effects based on the rate and extent of bacterial killing over time.
What 2 parts of a bacterium determine its shape?
cell wall and DNA
What has the author Arend Jan Slotboom written?
Arend Jan Slotboom has written: 'Application of lipolytic enzymes in the synthesis of monoacyl phosphoglycerides and plasmalogens' -- subject(s): Lipolytic enzymes, Phospholipids
What foods are spoiled by lipolytic bacteria?
Foods rich in fats and oils, such as dairy products (like milk and cheese), meat products, and baked goods, can be spoiled by lipolytic bacteria. Lipolytic bacteria break down fats into fatty acids, which can lead to rancid flavors and off-odors in the food.
If glucose broth medium is used without a pH indicator how can you determine whether a particular bacterium fermented glucose?
you can use a durham tube and observe the formation of a bubble for the microbes that are expected to produce gas

How can PCR be used to identify an unknown bacterium?
PCR, or polymerase chain reaction, can be used to identify an unknown bacterium by amplifying specific regions of its DNA. This amplified DNA can then be sequenced and compared to known sequences in databases to determine the identity of the bacterium.
Food that might be spoiled by lipolytic bacteria?
Any food that has a high fat content....
How do you determine whether a rock is a rhyolite or an andesite?
The composition of the rock will determine whether it is a rhyolite or an andesite.
Is a host a living thing as in cells?
Yes, the host is living, whether it be a host for a virus, a worm, or a bacterium.
