Technical Support

Tripotassium phosphate is a Bactericid with bactericidal activity primarily against Gram-negative bacteria. Tripotassium phosphate reduces the population counts of Enterobacteriaceae and Campylobacter in poultry skin rinsates. Tripotassium phosphate fails to reduce the population count of Enterococcus in poultry skin rinsates.

Description

In Vitro

Tripotassium phosphate (1-3% (w/v)) significantly reduces the counts of aerobic bacteria, Enterobacteriaceae and Campylobacter in the rinse solution of commercial broiler skin, but fails to reduce the count of Enterococcus^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay^[1]

Cell Line:	Enterobacteriaceae, Campylobacter, Enterococcus, aerobic bacteria
Concentration:	1% (w/v); 2% (w/v); 3% (w/v)
Incubation Time:	single application
Result:	Reduced aerobic bacteria counts to log10 4.09 cfu/mL (from control log₁₀ 4.51 cfu/mL) at 1% dose; no Enterobacteriaceae or Campylobacter were recovered. Reduced aerobic bacteria counts to log₁₀ 3.89 cfu/mL at 2% dose; no Enterobacteriaceae or Campylobacter were recovered. Reduced aerobic bacteria counts to log₁₀ 3.95 cfu/mL at 3% dose; no Enterobacteriaceae or Campylobacter were recovered. Did not significantly reduce Enterococci counts (ranging from log₁₀ 2.29 to 2.74 cfu/mL vs. control log₁₀ 3.02 cfu/mL).
