Lactobacillus plantarum CNRZ 1228 exhibited heme-dependent catalase activity under environmental conditions similar to those encountered during sausage fermentation. The 1,455-bp catalase gene (katL) was cloned and encoded a protein of 484 amino acids. Expression of katL in a heterologous host showed that katL encodes a functional catalase. PCR screening of selected strains of lactic acid bacteria for katL indicated the presence of similar genes in other strains of lactobacilli.
植物乳杆菌CNRZ 1228在与香肠发酵过程中遇到的环境条件相似的情况下表现出依赖血红素的过氧化氢酶活性。克隆了1455 bp的过氧化氢酶基因(katL),其编码一个由484个氨基酸组成的蛋白质。katL在异源宿主中的表达表明katL编码一种功能性过氧化氢酶。对选定的乳酸菌菌株进行katL的PCR筛选表明,其他乳酸杆菌菌株中存在相似基因。
