S ummary : The heat resistance of spores of Bacillus coagulans strain Sp. 33, isolated from canned chopped spinach, has been determined. It appeared to be higher in 1/40 M phosphate than in 1/15 M phosphate and higher at pH 6°8 than at pH 6°0. In 1/40 M phosphate buffer of pH 6°8 the calculated D 110 was 2°4 min. In chopped spinach of pH 6°2 the calculated D 110 was 0°84 min. In addition a simple and reliable method of assessing the thermal resistance of micro‐organisms in thermal death time tubes is reported.
