Chlamydomonas nivalis have been found on the surface of "C. nivalis" cysts. The unknown bacteria were not detected in control samples that did not contain "C. nivalis" which strongly suggests that it must be associated with the algae. Another bacterium, "Mesorhizobium loti", was found as contamination in a "C. nivalis" culture, but further testing suggested that this bacteria may be synthesizing vitamin B12 for the algae. In cryoconite holes "C. nivalis" can be found among bacteria, virus-like particles, ciliates, and Chlorophyte species. Ice worms have also been found to live preferentially under "C. nivalis" in glaciers, possibly using the algae as a
