Long-term preservation methods for extreme thermophilic chemolithoautotrophic bacteria representing various species are described. The cultures were cryopreserved in liquid nitrogen under anaerobic conditions using 5% dimethylsulfoxide as a cryoprotectant. For easy storage and transport, the cultures were successfully liquid-dried, directly from the liquid phase without involving freezing under semiaerobic conditions using effective protective agents such as ethylenediamine and meso-inositol. The tested cultures showed good stability and survival rates after drying, after cryopreservation and on long-term storage. All tested strains were successfully preserved and reactivated within relatively short time. The viability, stability and ability of chemolithoautotrophic growth was not affected. Cryopreservation, liquid-drying and reactivation under microaerobic conditions proved very effective for these oxygen sensitive cultures.
