The Role of Coformulants in Preventing Bacterial Biotransformation of IPBC
2002 - IRG/WP 02-10436
The inhibitory effects of disodium tetraborate decahydrate and benzalkonium chloride (BAC), two common coformulants of IPBC in antisapstain treatments, on an IPBC-transforming enterobacterial isolate ‘W1’ were determined by their effect on the specific growth rate constant in vitro. The IC50s of IPBC, BAC and borate were found to be 0.46, 0.026 and 5.7 mM respectively. The IC50 of the Arch ant...

Studies on the Toxicity of IPBC and Other Biocides to Bacteria
2004 - IRG/WP 04-10544
Twenty-six strains of bacteria were isolated from IPBC-, Bethoxazin- and creosote-enrichment. These were found to fall into six principal clades: enterics, pseudomonads, Stenotrophomonas, Actinomycetes, Alcaligenes and Bacillus. Of these, only the last group was largely incapable of the dehalogenation of IPBC. Six representative strains were chosen for further study, and the ability of these six b...
