乾酪乳桿菌（學名：Lacticaseibacillus casei）又稱C菌，是乳桿菌屬的一種，存在於人類的腸道及口腔。文獻記載這個獨特的菌種除了可在廣泛的pH值及溫度的範圍內存活，還可以促進嗜酸乳桿菌的成長，而嗜酸乳桿菌又可生產澱粉酶，一種碳水化合物的消化酶。乾酪乳桿菌被認為是一種可安全食用的益生菌。

此物種的命名歷史極為混亂。^[1]大部分原先被認定為此種的實用菌株，包括ATCC 334、Lc01、代田菌、DN-114001，都實際上屬於副乾酪乳桿菌（L. paracasei）。^[2]

代田菌

益力多就是由「代田」菌株發酵而成

代田菌（L. casei Shirota）是乾酪乳酸菌的一株，由日本醫學博士代田稔培育出來的株種，為養樂多的招牌菌種。2013年，芬蘭科學家從酸奶中提取出代田菌並完成了測序。^[3]
