The enhancing effect of haem compounds on the growth of Escherichia coli, Staphylococcus aureus and Streptococcus agalactiae in whey cultures was studied turbidometrically. Catalase, myoglobin and haemoglobin in concentrations 10(-5) to 10(-3) M enhanced bacterial growth. One explanation of this was the availability of iron by these haem compounds for the bacteria. However, evidence from experiments on free radical generating systems by t-BHP and hydrogen peroxide indicated that haem compounds scavenge activated oxygen products and so protect bacteria from oxygen toxicity.
采用比浊法研究了血红素化合物对乳清培养基中大肠杆菌、金黄色葡萄球菌和无乳链球菌生长的促进作用。浓度为10(-5)至10(-3)M的过氧化氢酶、肌红蛋白和血红蛋白可促进细菌生长。对此的一种解释是这些血红素化合物可为细菌提供铁。然而，由叔丁基过氧化氢和过氧化氢引发的自由基生成系统实验证据表明，血红素化合物可清除活性氧产物，从而保护细菌免受氧毒性的影响。
