A new inexpensive and simple method for preserving microorganisms has been developed. Natural polymers of acacia gum and pullulan were used to preserve model bacteria Escherichia coli and Bacillus subtilis via immobilization and storage under various conditions. Formulation of E. coli and B. subtilis in acacia gum significantly increased the viability of both cultures during desiccation at 40 degrees C as well as during the storage at various temperatures and relative humidity. In the ranges of… CONTINUE READING
