The survival rates of 10 species of microorganisms were investigated after freeze-drying and preserving in a vacuum at 5 degrees C. The survival rates varied with species. The survival rates immediately after freeze-drying were different among yeast, gram-positive bacteria, and gram-negative bacteria, and the change in the 10-year survival rate was species-specific. The survival rate of yeast, ...

Polyamine patterns of 75 strains of actinobacteria belonging to the genera Agrococcus, Agromyces, Aureobacterium, Brevibacterium, Cluvibacter, Corynebacterium, Curtobacterium, Microbacterium, Rathayibacter, and Tsukamurellu were analyzed in order to investigate the suitability of this approach for differentiation within this group. The results revealed that the overall polyamine contents differ...
