I want to know the answer to the following question:
What is the by-product of non-repiratory anaerobes?
All the background I'm provided with is that "These processes are also important in biological responses to pollution; for example, sulfate-reducing bacteria are largely responsible for the production of the highly toxic forms of mercury (methyl- and dimethylmercury) in the environment. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste.". Is that enough to answer the question?
Answer: yes
