Question

Do you think the atmospheric temperature and soil temperature will have an impact on the organisms you are able to culture? Why? Also, what are two examples of nutrients soil bacteria may require to grow on a culture plate?

Answer 1

Do you think the atmospheric temperature and soil temperature will have an impact on the organisms you are able to culture?

Yes, the atmospheric temperature and soil temperature will have an impact on the organisms that are able to culture, because the proliferation and microbial activity among the microorganisms will differ under different temperature conditions. If we consider mesophilic microbes, it will show high growth and activity in moderate temperature, while thermophilic microbes are able to live at relatively high temperatures.

What are two examples of nutrients soil bacteria may require to grow on a culture plate?

Azospirillum and Actinomyces are the two examples of soil bacteria that require nutrients to grow on a culture plate. Because the growth of bacteria, including Actinomyces is slow compared to other microorganisms, such as fungi, hence they may get masked in culture plates if grown in ordinary nutrient media.
