REPORT ON CULTURE CONSERVATION OF ACTINOMYCES AND MOLDS
放线菌和霉菌菌种保藏研究报告

The sand tube method for the preservation of 244 strains of Actinomyces at room temperature through a period of 29 years has been tested. The survival rates (%) of these strains were 96 for 6 yrs; 91 for 9yrs; 88 for 11yrs; 78 for 14yrs; 76 for 15yrs; 74 for 17yrs; 70 for 20yrs; 59 for 22 yrs ; 47 for 25 yrs ; 40 for 27 and 37 for 29 yrs . The antimicrobiai activities and antibiograms of existing strains were identical with their original strains. The conservation of 12 genera. 216 strains of molds at room temperature for 16 yrs was carried out by moldy bran method. Their survival rates varied from 0 to 100% depending on their species. All of them deceased at 16th years.
