Final answer:
The two groups of bacteria that produce taste and odor compounds in water are Cyanobacteria and Actinomycetes. Cyanobacteria are photosynthetic aquatic bacteria, and Actinomycetes are Gram-positive bacteria involved in decomposition and producing earthy odors. The correct answer to the question is B) Cyanobacteria and Actinomycetes.
Step-by-step explanation:
The two groups of bacteria that are known to produce taste and odor compounds in water are Cyanobacteria and Actinomycetes. Cyanobacteria, often referred to as blue-green algae, are photosynthetic bacteria found in aquatic environments. They may bloom under certain conditions, leading to the production of compounds that can affect water taste and odor.
Actinomycetes are a group of Gram-positive bacteria that include species important in the decomposition of organic wastes. They are known for their earthy or musty odor compounds which can also have an impact on water quality.
The correct answer to the question is B) Cyanobacteria and Actinomycetes.
