This paper reveals the technological properties of lactic acid bacteria isolated from raw milk (colostrum and mature milk) of Wagyu cattle raised in Okayama Prefecture, Japan. Isolates were identified based on their physiological and biochemical characteristics as well as 16S rDNA sequence analysis. Streptococcus lutetiensis and Lactobacillus plantarum showed high acid and diacetyl-acetoin production in milk after 24 h of incubation at 40 and 30°C, respectively. These strains are thought to have potential for use as starter cultures and adjunct cultures for fermented dairy products.
本论文揭示了从日本冈山县饲养的和牛（初乳和成熟乳）中分离出的乳酸菌的技术特性。通过生理生化特性和 16S rDNA 序列分析对分离物进行了鉴定。在 40 和 30°C 下培养 24 小时后，唾液链球菌和植物乳杆菌在牛奶中表现出较高的产酸和双乙酰-乙酰基。这些菌株有望作为发酵乳制品的 starter 培养物和添加剂培养物使用。
