  • Comparatively few chemical agents, however, possess sporicidal activity (Waites and Bayliss, 1980; Russell, 1982a; Gould. 1983), although most compounds appear capable of inhibiting either germination or outgrowth of spores in their development into vegetative cells.

  • What is the difference between sporicidal and sterilant?

Sterilant鈥擜n agent that destroys all forms of microbial life including fungi, viruses, and all forms of bacteria and their spores.

  • What is the shelf life of a sporicidal solution?

  • Only when the solution is 鈥渁ctivated鈥?(made alkaline) by use of alkalinating agents to pH 7.5鈥?.5 does the solution become sporicidal. Once activated, these solutions have a shelf-life of minimally 14 days because of the polymerization of the glutaraldehyde molecules at alkaline pH levels.

  • Are phenolics sporicidal or bactericidal?

  • Manufacturers鈥?data using the standardized AOAC methods demonstrate that commercial phenolics are not sporicidal but are tuberculocidal, fungicidal, virucidal, and bactericidal at their recommended use-dilution. Attempts to substantiate the bactericidal label claims of phenolics using the AOAC Use-Dilution Method occasionally have failed 416, 737.
