The term that accurately describes a substance capable of destroying micro-organisms is "bactericide." A bactericide is specifically designed to kill bacteria and is often used in medical and hygiene contexts to prevent infections. It works by targeting essential components of bacterial cells, leading to their destruction.

Antiseptics, while also used to eliminate microorganisms, are typically employed on living tissues and are often less potent than bactericides in terms of bacterial cell death. Disinfectants are more potent agents used on inanimate surfaces to kill or inactivate infectious micro-organisms and may not be safe for use on skin due to their strength. Bacteriostatic agents, on the other hand, inhibit the growth and reproduction of bacteria but do not necessarily kill them. Each term has its specific application and effectiveness based on the context in which they are used.
