Hi, I'm currently planning on a project for my school's science fair. I was thinking about the cellulase proteins topic, because I thought it would be interesting if humans can digest cellulose just like herbivores... I found out that breaking down cellulose requires many steps, thus demands a list of different kind of enzymes, not only one kind as I initially thought. So I have a few questions and I need some advices ^^'. Where can I find a full list of bacteria and enzymes that involve in cellulolysis in cows? I tried to search but all they have was some general info... After that, I would like to find out if one can somehow integrate the cellulase-producing-bacteria's genes to that of a bacteria that lives in human's stomach, the E.Coli for example, so human would have a continuous source of cellulase. Is that actually possible? If it is, what method should I use? And would it be possible to do it in a high school's lab in about 30 days? Thank you so much in advance .
