少孢根霉学名Rhizopus oligosporus)是根霉属的一种真菌,常作为制作丹贝发酵剂,它可以长出白色蓬松的菌丝体,与被部分分解的大豆结合成白色的饼状食品[1],这种真菌可以在印尼摄氏30-40度的环境下快速生长,且脂肪分解英语Lipolysis蛋白酶解的活性高,又可以分泌抑制其他微生物生长的物质,因而适合用来生产丹贝[2][3]。少孢根霉可能于数个世纪前,在印尼由微孢毛霉英语Rhizopus microsporus驯化而来,并在驯化的过程中丢失了制造根瘤菌素英语rhizoxin与rhizonin等毒素的基因[4]

少孢根霉被食用后,会在人体中继续分泌抗生素,抑制金黄色葡萄球菌枯草杆菌革兰氏阳性菌的生长,有研究显示常食用丹贝的人较不易发生肠道感染[5]

有研究将少孢根霉视为微孢毛霉英语Rhizopus microsporus变种Rhizopus microsporus var. oligosporus[6]。2014年,分子种系发生学的研究结果显示少孢根霉与微孢毛霉是同一种物种,两者互为同物异名[7]
