Answer

Neither A) desiccation nor B) osmotic pressure is typically used for long-term bacterial culture preservation. Explanation 1. Identify Preservation Methods Desiccation and osmotic pressure are methods used to control microbial growth, but not typically for long-term preservation. 2. Determine Common Preservation Techniques Long-term preservation often uses freezing or lyophilization (freeze-drying), not desiccation or osmotic pressure.
