Is staphylococcus aureus a psychrophile?
yes its a mesophile with growth optimum around 20 to 45oC a minimum of 15 to 20oC and a maximum of about 45oC or lower.
12 A given species of bacteria is known to require 100 different nutrients 99 of these are in optimum quantities but one is limited You would expect that population growth would be?
limited by the quantity of that nutrient - its the limiting stepthe actually rate of growth depends on the relationship between tha nutrient and the growth rate if its a linear relationship then growth rate = k[Nutrient]
What is the Optimum temperature for s.albus?
The optimum temperature for S.albus is about 98.6 degrees Fahrenheit. This also means that its optimum temperature in Celsius would be 37 degrees.
What happens at optimum pH?
Well without specifying the parameters its impossible to say; the definition of optimum pH would be, the pH at which point the optimum results of a reaction are achieved.
What effect would a higher pH have on the temperatures optimum for invertase?
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
Definition of a hibitory substance relative to a water sample?
A hibitory substance relative to a water sample is a substance that allows for the growth of microorganisms. This would be like a contamination of water that can cause disease to spread.
What factors would account for an absence of growth on a streak plate?
* Wrong temperature in the incubator * Not enough time in the incubator * No culture was obtained on the inoculating loop * Wrong type of agar for optimum growth (nutrients,etc.)
What scientist would study microorganisms?
A microbiologist.
What would happen if we didn't havemicrobes?
Without microorganisms, we would die very quickly. For every 1 "human" cell in your body, there are about 10 "other" microorganisms in and on your body. Every aspect of life revolves around microorganisms, such as bacteria and fungi, essential to every aspect of life. Without microorganisms, everything would cease to exist.
What are the 5 different germs on your palm?
There are probably several thousand different kinds of microorganisms growing on your palm. Some are protective and reduce growth of harmful germs. If you eliminated ALL microorganisms from your skin the next harmful germs you picked up would probably do severe damage to your skin and make you very sick.
How do you stop microorganisms?
You stop microorganisms through different ways of cleaning. An example would be the universal precaution Hand washing. With this you get 99.9% of germ or microorganisms out your hands. Other exmaples would be sterilization, boiling, cleaning or scrubbing.
Do microorganisms affect soil?
Nitrite formation by rhizoplane microorganisms of rice seedlings was examined in comparison with that by nonrhizosphere paddy soil microorganisms. Effect of nitrite on root growth of rice seedlings was also investigated under aseptic water culture condition. Rhizoplane microorganisms accumulated much nitrite than the other microorganisms in a root extract medium. The accumulated nitrite maintained a stationary level for more than 2 days. In glucose enriched media, both group of microorganisms accumulated nitrite only temporarily. Formation of lateral roots and root hairs was stimulated in the solution containing 1.12-11.2 ppm NO_2^--N but elongation of primary roots was depressed under 5.6-11.2ppm NO_2^--N concentrations. Growth of rice seedlings was inhibited at concentrations higher than 5.6 ppm. Comparative studies indicated that effect of soil microorganisms on root morphology would have been caused by nitrite produced by rhizoplane microorganisms. Additional Index Words : nitrite formation, rhizoplane microorganisms, rice root, aseptic culture.
