   <abstract xml:lang="ru">
    <p>Диоксид хлора (ClO2) в настоящее время признан одним из наиболее эффективных дезинфектантов в отношении бактерий, в том числе их споровых форм, вирусов, грибов и простейших. Роль рН среды в бактерицидной эффективности диоксида хлора вызывает значительные разногласия среди исследователей. В работе представлены данные по влиянию рН в диапазоне активной кислотности от 3 до 11 на бактерицидную эффективность диоксида хлора относительно тест-культуры Escherichia coli, как основного санитарно-показательного микроорганизма для молочного производства. Проведены исследования влияния различной бактериальной обсемененности растворов на бактерицидную эффективность ClO2. Установлен уровень содержания жизнеспособных клеток в растворах 105 КОЕ/см3. Показано комплексное влияние активной кислотности среды и концентрации диоксида хлора на бактерицидную эффективность относительно тест- культуры Escherichia coli. Эффективность обеззараживания, т. е. обеспечение гибели 99,99 % тест-культуры Escherichia coli имеет тенденцию к увеличению с понижением рН растворов. Так, минимально исследованная концентрация диоксида хлора 1,7 мг/дм3 (0,05 % по препарату) достаточна для уничтожения клеток только в кислой среде с рН 3. Концентрация ClO2 2,5 мг/дм3 (0,075 % по препарату) уничтожает кишечную палочку в диапазоне рН от 3 до 5. Для полной инактивации Escherichia coli в растворах с рН 8 и ниже требуется концентрация 3,3 мг/дм3 (0,1 % по препарату) ClO2. Диоксид хлора в концентрации 6,6 мг/дм3 (0,2 % по препарату) убивает тест-культуру в диапазоне рН от 3 до 10. Во всем исследованном диапазоне активной кислотности эффективная концентрация дезинфектанта составляет 8,3 мг/дм3 (0,25 % по препарату).</p>

    <p>Chlorine dioxide (ClO2) is one of the most effective disinfectants against bacteria, spores, viruses, fungi, and protozoa. However, the jury is still out on the role of pH in its bactericidal performance. This research tested the effect of pH 3–11 on the antibacterial properties of chlorine dioxide against Escherichia coli as the main sanitary indicator in dairy production. The experiment involved solutions with various levels of bacterial contamination with a viable cell count of 105 CFU/cm3. The pH of the medium and the concentration of chlorine dioxide exerted a complex effect on E. coli. The 99.99% disinfection performance occurred at lower pH values. The minimal concentration of chlorine dioxide in this research was 1.7 mg/dm3 (0.05%). It was efficient against E. coli only at pH 3 while 2.5 mg/dm3 (0.075%) was efficient at pH 3–5. A concentration of 3.3 mg/dm3 (0.1%) provided complete inactivation of E. coli in solutions with pH ≤ 8. Chlorine dioxide at a concentration of 6.6 mg/dm3 (0.2%) killed the test culture at pH 3–10. The effective concentration across the total pH range was 8.3 mg/dm3 (0.25%).</p>
