I have another "essay" question. You received water from a local lake to determine the bacterial cell count, you did the count using both direct microscopic count and the plate count methods. Which methods would likely give you a higher bacterial count? Why? I thought at first it was the direct microscopic count because it counts both dead and live cells. Then I started thinking it was the late count method because of the way the cells/colonies are counted. Now I'm just not sure. Any help would be appreciated.

I believe I was over thinking this question. So bacteria that doesn't need oxygen can use another organic compound as an electron acceptor? I'm sorry, I'm sure I sound dumb but my instructor has serious confused me on this chapter.

I have an essay question on one of my assignments and I would love some help or maybe to be lead in the right direction. I'm struggling with this chapter in Microbiology and my instructor is just not helping me understand it! The question is : Is molecular oxygen the only substance that can be used as an electron acceptor in bacterial metabolism pathways? Why? Any help would be greatly appreciated. Know of a website or online lecture I could watch that might help explain? Thanks!
