I'm doing research on anaerobic bacteria. In the fall I took mud samples from a bog and have been working with them but I didn't take enough. Now winter has rolled around (Im in Canada) and all the bogs are frozen over. I need more material to work with — is it possible to make a mud mixture myself and carry over the bacteria? If so could anyone help me out with the mixture ratios? Is contamination a concern here (I would assume not)? And how long would the propagation take?
