Lactobacillus coprophilus subsp. confusus (NCDO 1586) and 18 other strains of slime-forming heterofermentative lactobacilli obtained from diverse sources are considered to form a new species on the basis of their physiological characteristics and similarities of their pyruvate reductases and lactate dehydrogenases. It is suggested that these strains should be named Lactobacillus confusus (Holzapfel & Kandler) comb. nov. (L. coprophilus subsp. confusus Holzapfel & Kandler), reasons being given. The type strain is NCDO 1586 (NCIB 9311, ATCC 10881). Strains of Lactobacillus vermiforme and Lactobacillus viridescens also form slime. However, L. vermiforme was readily separated from the other two by the criteria used. Although physiological characteristics separated L. viridescens from L. confusus, a relationship between these two species and also between them and the leuconostocs was indicated by the properties of the pyruvate reductases and lactate dehydrogenases. The slime produced by all species was found to be a glucan, probably a dextran, containing primarily alpha-1-6-glycosidic linkages.
粪源嗜乳酸杆菌混淆亚种(NCDO 1586)以及从不同来源获得的其他18株形成黏液的异型发酵乳杆菌,基于它们的生理特征以及丙酮酸还原酶和乳酸脱氢酶的相似性,被认为构成一个新物种。建议将这些菌株命名为Lactobacillus confusus(霍尔扎普费尔和坎德勒)新组合(粪源嗜乳酸杆菌混淆亚种霍尔扎普费尔和坎德勒),并给出了理由。模式菌株为NCDO 1586(NCIB 9311,ATCC 10881)。蠕形乳杆菌和绿色乳杆菌的菌株也会形成黏液。然而,蠕形乳杆菌很容易通过所使用的标准与其他两种菌区分开来。虽然生理特征将绿色乳杆菌与混淆乳杆菌区分开来,但丙酮酸还原酶和乳酸脱氢酶的特性表明这两个物种之间以及它们与明串珠菌之间存在关联。发现所有物种产生的黏液都是一种葡聚糖,可能是一种右旋糖酐,主要含有α-1-6糖苷键。
