Did growth happen at a different level in agar deep?
The agar deep stab is an experiment to determine the affect that oxygen has on a culture. If growth is found only at the top, this indicates an obligate aerobe. If growth is found at the bottom only, then it would be a obligate anaerobe. If growth is found all throughout the stab, this would indicate a facultative anaerobe. Obligate aerobes require oxygen to survive. Obligate anaerobes cannot survive with oxygen present. Facultative anaerobes can survive in both cases but usually prefer aerobic conditions.
What are the surface colonies on a pour plate larger than those within the medium?
The surface colonies on a pour plate larger than those within the medium especially aerobic bacteria within the medium would be a restriction of growth. The restriction of growth would be due to the lack of oxygen.
How would you expect the growth on the plates inside the jar to differ from the plates incubated outside the jar?
I would expect the growth on the plates inside the jar to be more consistent and potentially greater due to a controlled environment, which may provide optimal humidity and temperature. In contrast, plates incubated outside the jar could experience fluctuations in environmental conditions, leading to variable growth rates and possibly exposure to contaminants. Additionally, the enclosed jar may limit the exposure to competing microorganisms, allowing for more effective growth of the desired organisms.
When would expect to see a species go through a logistic growth pattern?
A species is expected to go through a logistic growth pattern when resources are limited. Initially, the population grows rapidly (exponential growth), but as resources become scarce, the growth rate slows down and eventually stabilizes at the carrying capacity of the environment.
If over a period of 10 years a population has a logistic growth rate you would expect to see?
Initially rapid growth, followed by a tapering off as the population approaches its carrying capacity. Prior to reaching carrying capacity, the growth rate would decline as competition for resources increases and limiting factors come into play, resulting in a stable population size over time.
Where would you expect to see growth of a strict aerobe anaerobe microphile and facultative anaerobe in the fluid thioglycollate medium?
The sodium thioglycollate in the broth creates a redox potential in the tube, with higher levels of oxygen at the top of the tube, and a complete absence of oxygen at the bottom of the tube.Fluid thioglycollate broth also typically contains a redox potential indicator such resazurin, which produces a pink color in an oxidized environment. As with the BHI media, organisms will only be able to grow where their oxygen requirements are met, and will localize to the area(s) of their oxygen requirements in the fluid thioglycollate broth.Obligate aerobes will grown on or very close to the top (high oxygen). Obligate anaerobes will only grow on the bottom (no oxygen). Facultative anaerobes will grow throughout but more on top. Microaerophiles will be found in a band where only a small amount of oxygen is found. They would be close to but not on the top.
Which type of organism aerobe anaerobe microaerophile facultative anaerobe would most likely be affected negatively by the use of old media?
I would think an aerobic organism would do the worst in an oxygen poor media, which would be one of the results of having an older media sitting around.
Bergey's Manual describes Streptococcus and Escherichia as faculative anaerobes How do the oxygen requirements of these organisms differ...Which one could correctly be called an aerotolerant anaerobe?
Streptococcus is an obligate anaerobe and therefore lacks catalase. However, Streptococcus would be considered an aerotolerant anaerobe because, even though it lacks catalase to break down hydrogen peroxide, it also lacks the cytochrome system that would produce hydrogen peroxide in the first place. Therefore, it is not aerobic, but it is tolerant of aerobic conditions.

How microbes are classified based on their oxygen preferences?
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
What growth you are expecting on your salary?
I would expect 30% of my current salary.
A bacteium would be killed by exposing it to oxygen would be a?
A bacterium to which oxygen is cytotoxic is known as an obligate anaerobe.
Would you expect growth of crop in a farm or in a topographic level?
On leveled land~!
Where would you expect to find in a country with zero population growth?
In a country with zero population growth, you would expect to find a stable population size where the number of births equals the number of deaths. This would mean the population is not increasing or decreasing over time.
What would you expect to happen to the vaginal microbiota of a patient with a defect in estrogen production?
Growth of opportunistic pathogens would increase.
what growth results would you expect under white lights?
You can expect normal plant growth. The white light is similar to the sun in having all the colors so this can help the plant to grow naturally if there is not a lot of sun.
