Two antibiotic P roducing strains, streptomycin and gentamicin, were tested for cryopreservation methods at-196℃ as reported in this paper. The preserved strains was being treated by both different freezing and thawing rates and with different cryo-protective agents. Re-ults showed that morphology and spore constitution of the bacterial colonies did not have any changes. The surviving rate of the strains were higher than 90%, and the two producer strains' activities in shake flask tests using cryopreservation...

Two antibiotic P roducing strains, streptomycin and gentamicin, were tested for cryopreservation methods at-196℃ as reported in this paper. The preserved strains was being treated by both different freezing and thawing rates and with different cryo-protective agents. Re-ults showed that morphology and spore constitution of the bacterial colonies did not have any changes. The surviving rate of the strains were higher than 90%, and the two producer strains' activities in shake flask tests using cryopreservation method were proved higher than those of soil preservation method ones.

本文研究了两种产生抗生素的放线菌种——链霉素和庆大霉素产生菌低温(-196℃)保存的方法,讨论了在保存过程中的降温速率、复温速率以及抗冻剂等对保存效果的影响,经低温保存后的菌种,其菌落形态、孢子结构均无明显可见的变化,存活率大于90%,摇瓶结果优于砂土保存方法。

The present paper deals with the method of cryopreservation (-196℃) of two antibiotic sctinomyces strains (Streptomycini and Gentamycini )and the effects of the freezing and thawing rates. The growth forms and spore structures of cryopreserved actinomyces show no visible changes and consequently their survivals are more than 90%. Furthermore, the antibiotics-producing capacity of cryopreserved actinomyces is superior to thai of soil preservation.
