What is thermophilic bacteria?
The thermoduric bacteria refers to the bacteria that can survive to varying extent. This type of bacteria is able to survive the pasteurization process.
Explain why bacteria do not completely engulf the earth even though they reproduce rapidly enough to do so?
Bacterial growth is constrained by several parameters such as the level of nutrients around them, the temperature they grow at, pH and whether they grow in air or not just to name a few. No single bacteria can grow in all conditions so therefore bacteria can never engulf the earth. Most bacteria have fairly specific growth conditions.
What is danger growth zone?
The temperature that bacteria grows in best. I believe it's between 40 and 110 degrees.
How do you measure bacteria in a petri dish?
When bacteria is grown in an Agar plate, one quantitative method to measure growth is using a counting chamber. Another method is using viable plate counts.
What is macconkey agar made out of?
Macconkey agar consists of agar, lactose, peptone, neutral red dye, crystal violet dye & bile salts. Bile salts inhibit growth of Gram positive bacteria & allow growth of Gram negative bacteria only. It differentiates lactose fermentating Gram negative bacteria from non lactose fermentating Gram negative bacteria.
Can a sebaceous glands kill bacteria?
true! Sebaceous glands, that produce this waxy oily secretion called SEBUM which lubricates the hair shaft and inhibits bactirial growth withing the surrounding area.
Why can salted fish meat last for hour without spioling?
because the salt draws out the moisture from the fish and inhibits bacteria growth. because the salt draws out the moisture from the fish and inhibits bacteria growth.
When a substance is added to solid medium which inhibits growth of unwanted bacteria but permits the growth of wanted bacteria the medium is known as?
selective medium
What does antibacterial really mean?
Antibacterial means: "Any drug that destroys bacteria or inhibits their growth".
What is the purpose of adding rose Bengal to the agar medium for the growth of the fungi?
rose bengal inhibits growth of bacteria, thus promoting the growth of fungi, mold and yeast.
Why blood agar medium producing less contamination?
as it is a selective media for streptococci it inhibits the growth of other bacteria.
Can botulism grow in the refrigerator?
No, botulism bacteria cannot grow in the refrigerator because the cold temperature inhibits their growth.
Which is not a function of the hypothalamus?
The hypothalamus stimulates or inhibits secretion of hormones by the pituitary gland. One of these is GH or Growth Hormone.
Why methylene blue inhibits gram positive bacteria?
Methylene blue inhibits gram positive bacteria by disrupting their cellular respiration. It interferes with the electron transport chain, leading to a decrease in ATP production, which is essential for bacterial growth and survival. This ultimately results in the inhibition of bacterial growth and reproduction.
Why are crystal violet agar 7.5 sodium chloride agar considered selective media?
7.5% NaCl inhibits growth of certain bacteria. This type of selective media allows for the growth of Staph. A high concentration of NaCl alters the osmotic balance between the media and the bacterium, NaCl plasmolyzes the bacterium due to the hypertonicity of the medium. The circular shape of Staph allows it to better resist plasmolysis. Crystal Violet is a dye that inhibits the growth of certain Gram-positive bacteria, it does this by binding to the thick peptidoglycan layer preventing cross-linking and thus preventing cell growth.
Why do pigs sweat blood?
Pigs actually don't sweat blood, they have glands that produce a red-colored secretion that acts as a sunscreen and inhibits bacterial growth on the skin. This secretion is often mistaken for blood, giving rise to the misconception that pigs sweat blood.
What chemical is produced by a living organism that kills or inhibits growth?
Antibiotics are chemicals produced by living organisms that kill or inhibit the growth of other organisms, particularly bacteria.
