Among the Case Solutions products is PentaPrep, a pH neutral, multi-enzymatic pre-soak foam that includes five enzymes and surfactants, and comes ready to use as either a dense white foam or a liquid foam; and PentaZyme, a highly concentrated pH neutral, multi-enzymatic solution that includes five enzymes as well as alcohol for bacteriostasis
Quaternary ammonium compounds (quats) are surface-active agents with the property of producing bacteriostasis
in very high dilution.
Although American Association of Tissue Banks standards recommend that cultures be obtained before and after processing, these standards do nor address the potential problem of bacteriostasis
after processing or specify a culture method (4).
Acetic acid has been shown to penetrate into the bacterial cytoplasm resulting in a reduced internal bacterial pH and collapse the electrochemical proton gradient, leading a bacteriostasis
and death of susceptible bacteria such as cecal coliforms .
