In which situation are the actinomycetes likely to be most dominant?
A)extremely acid conditions too severe for most other microorganisms
B)low organic matter soils
C)cold,wet soils
D)soil with lots of fresh,easily decomposed residues
E)neutral,moist,warm soil with lots of partially decomposed residues

Question

Quizplus · Accepted Answer

Actinomycetes thrive in neutral to slightly acidic soils with plenty of organic matter, especially partially decomposed residues. They are known for their ability to decompose tough organic compounds like cellulose and chitin, and can out-compete other soil microorganisms when these compounds are abundant. Cold, wet soils and soils with little organic matter would not be ideal for actinomycete growth. Extremely acid conditions would likely be too harsh for most microorganisms, including actinomycetes.
