How bacteria can become harmful to microorganisms?
Bacteria compete with other bacteria and microorganisms by secreting toxins and antibiotic proteins.
Are amino acids microorganisms?
An amino acid is just a molecule that is a building block of proteins. They are not living and they aren't microorganisms.
How does an autoclave effectively kill microorganisms?
An autoclave effectively kills microorganisms by using high pressure and steam to reach temperatures above 250F (121C), which destroys the cell walls and proteins of the microorganisms, ultimately leading to their death.
Why would you not use heat to kill microorganisms in a protein-rich solution?
You certainly can use heat to kill microorganisms in a "protein-rich" solution if you don't care whether the proteins get denatured or not.
Why is silver nitrate and 2-propanol are often used to destroy microorganisms?
Silver nitrate and 2-propanol are used to destroy microorganisms due to their antimicrobial properties. Silver nitrate is effective against a wide range of bacteria, fungi, and viruses. 2-propanol, also known as isopropyl alcohol, denatures proteins in microorganisms, disrupting their cell membranes and killing them. Together, they provide a dual-action approach to effectively destroy microorganisms.
What is the group of proteins that are always present in the body to help white blood cells ingest microorganisms?
The group of proteins that are always present in the body to help white blood cells ingest microorganisms is called complement proteins. Complement proteins work alongside white blood cells to enhance the immune response by promoting inflammation, attracting phagocytes, and directly killing pathogens. They form an essential part of the innate immune system.
How formaldehyde acts as antiseptic?
Formaldehyde acts as an antiseptic by denaturing proteins and disrupting the cell membranes of microorganisms. This leads to the death of the microorganisms and helps prevent infection. Additionally, formaldehyde has a drying effect which helps in preserving tissues and preventing microbial growth.
How are microorganisms destroyed by moist heat?
Moist heat coagulates microbial proteins (including protein enzymes), inactivating them irreversibly.
Are b cells a group of proteins always present in the body to help white blood cells ingest microorganisms?
true
What is Macrozit?
Macrozil is used to treat bacterial infections including respiratory and tract. It works by inhibiting RBA proteins that synthesize sensitive microorganisms.
What is liofilisation?
The liofilisation is a method of conservation of products, perfect to preserve active principles characteristics (proteins, enzymes), microorganisms, chemical and natural products.
Why are some microorganisms more heat resistant than others?
Microorganisms have different heat resistance levels due to variations in their genetic makeup. Some microorganisms have developed heat-resistant structures or proteins that protect them from high temperatures. Additionally, certain microorganisms may produce spores or biofilms that provide protection during exposure to heat.
