What is phenyl ethyl alcohol agar?
Phenylethyl alcohol agar (PEA) is a selective media used to cultivate Gram (+)microorganisms. The active ingredient, phenylethyl alcohol, inhibits or reduces growth of Gram (-) microorganisms by interfering with DNA synthesis.
Why use isopropyl alcohol to inhibit bacterial growth?
Isopropyl alcohol is used to inhibit bacterial growth because it acts as a disinfectant. This kills the bacteria and prevent them from multiplying.
Why does this exercise call for an older 5 day culture of bacillus?
Culture age can affect sporulation. Bacteria don't produce spores during culture's growth, but by nutrient depletion.
How does alcohol affect an embryo?
It disrupts fetal growth patterns, especially the central nervous system. See : fetal alcohol syndrome.
Types of bacteria found in milk?
Found this answer on examville.com, when I was searching the net for my homework assignment.Milk supports the growth of a variety of bacteria including pathogenic one The different types of bacteria present in milk are, as follows: 1. Acid-fonning bacteria, such as Streptococcus lactis Str. faecalis Lactobacilli These ferment lactose, forming lactic acid, and lead to the formation of curd. 2. Alkali-fonning bacteria, such as Alkaligenes sp. Achromobacter Aerobic spore-forming bacilli These render the milk alkaline. 3. Gas-forming bacteria, such as Coliform bacteria Cl. peifringens Cl. butyricum These produce acid and gas. 4. Proteolytic bacteria, such as Bacillus subtilis B. cereus Proteus vulgaris Staphylococci Micrococci These bacteria are responsible for proteolytic activity. 5. Inert bacteria, such as Achromobacter Pathogenic bacteria Cocci They do not produce any visible change.

Why bacillus cereus more heat resistant than aspergillus Niger?
Even though they both contained spores, I believe the reason why A. Niger is less heat resistant is because it is a fungus and in the domain eukaryota. Therefore, it needs a level of humidity in the air to produce molds; an ability of most members of the fungi species. B cereus is a facultative anaerobe, and its bacterial growth generally occurs around 10-50 degrees celsius. While, a. Niger maximum temperature is around 40 degrees celsius.
What is an example of an biological contaminant?
Organisms such as mold or bacteria growing in it. and If conditions permit or cross contamination occurs food may be fertile ground for the growth of: Bacteria Like: Salmonella spp., Enterohaemorrhagic Escherichia coli, Campylobacter jejuni, Yersinia enterocolitica, Listeria monocytogenes, Bacillus anthracis, Bacillus cereus, Staphlococcus aureus, Clostridium botulinum, Clostridium perfringens, Vibrio vulnificus, Vibrio parahaemolyticus Viruses like hepatitis A virus, Norwalk viruses, Rotavirus Parasites like Toxoplasma gondii, Cryptosporidia, Giardia spp., Trichinella spiralis, Taenia solium, Anisakis spp.
