Microbial interaction is only responsible for some instances/types of rancidification. Oxidation and hydrolysis reactions can occur without microbes, although again the question becomes one of how quickly these reactions would occur at cryogenic temperatures (very slowly, but we are looking at potentially very long timespans here) and availability of species.
