Where can I Obtain Bacteria Species for Examination under a Microscope?

Question

I live in the UK, and would like to obtain some living bacteria/yeast species to examine under the microscope, and experiment with the effects of magnetic pulses/Radio frequencies/ultrasounds on the living microorganisms.

For instance, non-pathogenic E.coli, or Candida Albicans.

Answer 1

E. coli is normal flora in the intestines of humans. It helps us digest our food; just culture some stool and grow your own.

For the yeast; use Sacromyces cervasie, which is Baker's Yeast.
