What can be added to suppress bacterial growth on a fungi based Media?
Emmanuel Kennedy
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.

What is enrichment media in microbiology?
Enriched media is different from Enrichment media... Enriched media: Blood and other special nutrients may be added to general purpose media to encourage the growth of fastidious microbes. These specially forfited media are called as enriched media. e.g. Blood agar, Chocolate agar. Enrichment media: This is a media which promotes the growth of a particular organism by providing it with the essential nutrients and rarely contains certain inhibitory substance to prevent the growth of normal competitors. e.g. Selenite F broth- this media favours thegrowth of Salmonella also prevents the growth of normal competitors like E. coli . but E.Coli do not perish in the medium but they do not flourish like Salmonella
What is enrichment media?
Enriched media are the selective media in which substances like blood,serum,egg etc are added to the basal medium. They are used to grow the bacteria which are more exacting in their nutritional needs. eg-blood agar- enriched with blood loeffers serum slope-enriched with serum lowenstein jensen media-enriched with egg
What are the major requirements for bacterial growth?
The major requirements for bacterial growth are; Temperature (98.6°F is optimal), Ph Balance (ph7 or close to), Moisture (any amount), Light (Dark places grow more bacteria faster), and a food source.
The principal problem with inserting an unmodified mammalian gene into the bacterial chromosome and then getting that gene expressed is that?
bacteria cannot remove eukaryotic introns; bacterial dna does not contain introns like eukaryotic genes do so they had to be removed before being added to the plasmid.
The tryptophan operon is a repressible operon that is?
Turned off whenever tryptophan is added to the growth medium
Why glycerol is added in cetrimide agar?
as a source of carbon which important for bacterial growth
Preservatives such as citric acid are added to foods to interfere with bacterial growth This creates an acidic pH in the food Why does this affect the bacteria that are present?
An acidic environment causes bacterial enzymes to fail or work less efficiently.

How often is a growth ring added to the tree?
A growth ring is added everytime it gets married
Why is ampicillin added to the pound medium?
Ampicillin is an antibiotic that is usually used as a reporter gene in cloning. A plasmid containing the ampicillin resistance gene (as well as another target gene within the plasmid) is introduced into the bacterial host. If the bacterium has taken up the plasmid and is expressing the plasmid, it will be resistant to ampicillin. LB is used as a growth medium and ampicillin to verify the plasmid is within the bactrium. No growth means no plasmid in the bacterial host...
Magnetic field in multiple media?
The magnetic field in multiple media tends to increase as new media are added.
Why is agar added to nutrient media?
a thickener.
What is added to the atmosphere during bacterial decomposition of organic matter?
bacteria or fungi
Is blood heart infusion agar a defined or a complex medium?
Blood agar is enriched medium which are complex media to which an extra nutrient source (such as blood in this case) is added to encourage the growth of fastidious heterotrophs.
What is the purpose of antibiotics penicillin or streptomycin on PDA plates?
PDA is mainly used to Isolate Fungi but it is not selective media so Bacterial Colonies also come which makes mix culture. To avoid bacteria antibiotics like Penicillin or Steptomycin are added
