12/7/2023 0 Comments Gta 9/11![]() In this study, we compared the log reduction times of alkaline GTA on spores from 4 Bacillus species to fluorescent profiles generated using Alexa Fluorâ„¢ amine-reactive dyes. ![]() ![]() Bacillus species form highly resistant bacterial endospores that are commonly used as one of the most stringent test organisms for disinfection and sterilization. If true, the antimicrobial activity of GTA may directly correlate to the number of these available functional groups. A commonly proposed GTA kill mechanism suggests that it works by cross-linking accessible primary amines on important surface proteins. GTA kill times are extremely variable across different organisms, illustrating the need for a better understanding of GTA kill mechanisms related to different organisms. The precise antimicrobial mechanism of GTA remains debated. Alkaline glutaraldehyde (GTA) is a high-level chemical disinfectant/sterilant and has a broad microbial kill spectrum.
