Why penicilli is completely useless to treat a fungal infection?
Penicillin is an antibiotic that is effective against bacterial infections, not fungal infections. Fungal infections require antifungal medications, not antibiotics like penicillin, to effectively treat them. Using penicillin to treat a fungal infection will not be effective and could potentially worsen the infection by promoting the growth of the fungus.
What can be added to suppress bacterial growth on a fungi based Media?
Salts can be used to anybody but Ariel got on water but only fungi based Media such as potato dextrose agar PDA, some antibiotics are effective and can be used to suppress the growth of bacteria E.g penicillin, Ampicillin, streptomycin, Amoxicillin & rifampicin.
Which british scientists discovered the first anti biotic?
Sir Alexander Fleming, a Scottish bacteriologist, is credited with the discovery of the first antibiotic, penicillin, in 1928. He observed that a mold (Penicillium notatum) inhibited the growth of bacteria in a petri dish, leading to the identification of penicillin as an effective treatment for bacterial infections.
How did Alexander Fleming use mold to discovered penicillin?
Alexander Fleming discovered penicillin by observing that mold (Penicillium) had antibacterial properties. He noticed that a mold contaminant in one of his petri dishes was preventing bacterial growth. This led to the development of penicillin, the first antibiotic.
What are the factors that leads to fleming's invention to the field of biology?
Alexander Fleming's discovery of penicillin was influenced by a combination of factors, such as his background in bacteriology, his observations of bacterial contamination in laboratory cultures, and his serendipitous discovery of mold inhibiting bacterial growth. These factors converged to spark Fleming's interest in exploring the potential antibacterial properties of penicillin.
What type of drug is penicillin?
Penicillin is an antibiotic drug that is used to treat bacterial infections. It works by interfering with the growth of bacteria in the body and is effective against a wide range of bacterial strains.

What type of chemical agent retards bacterial growth?
Antibiotics are chemical agents that retard bacterial growth by targeting specific components of bacterial cells, which can inhibit their growth or kill them. Examples include penicillin, tetracycline, and ciprofloxacin.
How does penicillian work?
Penicillin works by inhibiting the synthesis of bacterial cell walls, specifically targeting the enzymes involved in forming peptidoglycan, a critical component of the bacterial cell wall. This disruption weakens the cell wall, leading to osmotic instability and ultimately causing the bacteria to burst and die. Penicillin is particularly effective against gram-positive bacteria, which have a thick peptidoglycan layer. By interfering with bacterial growth and replication, penicillin effectively treats various bacterial infections.
What are penicillins?
narrow range (affects ony gram positive) and resistance bacterial growth

How is penicilli used?
Penicillin is an antibiotic used to treat bacterial infections by inhibiting the growth of bacteria. It works by targeting the bacterial cell wall, causing the cells to rupture and die. Commonly prescribed for infections such as strep throat, pneumonia, and skin infections, penicillin is effective against various gram-positive bacteria. However, its use is limited by the emergence of antibiotic-resistant strains and allergies in some patients.
Why penicillin and streptomycin is added to culture medium?
Penicillin and streptomycin are added to culture mediums primarily to prevent bacterial contamination during the growth of desired microorganisms or cell cultures. Penicillin targets gram-positive bacteria by inhibiting cell wall synthesis, while streptomycin interferes with bacterial protein synthesis, effectively suppressing the growth of a broad range of gram-negative and some gram-positive bacteria. This combination helps ensure a sterile environment, allowing for the successful cultivation of the intended organisms without interference from contaminants.
What experiments lead to the discovery of penicillin?
Alexander Fleming who discovered penicillin. He was by accident kept a Staphylococcus bacterial plate open which was contaminated by a fungus. What he later noticed strikingly was an area of inhibition of the grown bacteria due to this fungus contamination! Fleming later concluded a chemical released from the fungus inhibited bacterial growth, by this he discovered penicillin!
Why does penicillin kill only actively multipling cells and lysozyme will kill cells in any stage of growth?
Penicillin inhibits transpeptidase, and enzyme that is necessary for bacterial cell wall synthesis. If a cell is not actively multiplying, then no cell wall synthesis is occurring and, therefore, penicillin does not inhibit the bacteria.
How did Alexander Fleming use mold to discovered penicillin?
Alexander Fleming discovered penicillin by observing that mold (Penicillium) had antibacterial properties. He noticed that a mold contaminant in one of his petri dishes was preventing bacterial growth. This led to the development of penicillin, the first antibiotic.
