Research Abstract	To evaluate the contribution of TC1 symbiont to the growth of host Trimyema, the growth properties and metabolites of symbiont-free protozoa strain were examined. As the results, the host's growth considerably decreased as low as 30% of maximum cell densities of symbiont-bearing strain, indicating the essential role of the symbionts for healthy growth of the host. On the other hand, propylene glycol was shown to be a candidate additive to protect Trimyema cell from freezing damage.
