-Disturbance can result from natural causes or from the activities of humans. Disturbance can be caused by physical stressors such as volcanic eruptions, hurricanes, tornadoes, earthquakes, and over geological time, glacial advance, and retreat.

-Humans can also cause physical disturbances, for example, through construction activities. Wildfire is a type of chemical disturbance caused by the rapid combustion of much of the biomass of an ecosystem and often causing mortality of the dominant species of the community such as trees in the case of a forest fire.

The strain of streptomycin-positive is those population of E. Coli which is significantly streptomycin resistant, while the negative strain has the opposite effect.

That's why if you want to grow up a large quantity of streptomycin-resistant, you must remarkably require to pick only a positive strain of streptomycin for E.Coli bacterium.

Therefore, if you want to grow up a large quantity of streptomycin-resistant E. coli, you would require to pick a colony of the bacteria from the streptomycin-positive plate and allow to grow it on a streptomycin-positive plate.
