Effect of calcium in assay medium on D value of Bacillus stearothermophilus ATCC 7953 spores.

Abstract

The D value of commercial biological indicator spore strips using Bacillus stearothermophilus ATCC 7953 was increased by higher calcium concentrations in assay media. The calcium concentration in assay media varied among the manufacturers. The calcium concentration in assay media is an important factor to consider to minimize the variation of D value.
