Abstract

Growth-promoting effect of rice bran extract and oil on Bifidobacterium and Lactobacillus was investigated. Hexane fraction of methanol extract and rice bran oil showed significant and strong promotive response to B. bifidum and B. longum at 10 and 5 mg ml$^{-1}$, respectively. This result indicates that the growth promoter of hexane fraction may be same as that of oil. Major fatty acids of rice bran oil were oleic acid 41.17%, linoleic acid 39.73%, palmitic acid 14.35%, linolenic acid 1.50%, stearic acid 1.27%, eicosamonoenoic acid 0.56%, arachidic acid 0.45%, lignoceric acid 0.24%, behenic acid 0.23%, myristic acid 0.23%, palmitoleic acid 0.15%, pentadecanoic acid 0.04%, heptadecanoic acid 0.04%, and eicosadienoic acid 0.03%. These results revealed the growth-promoting effect on B. bifidum and B. longum may be caused by rice bran oil containing various fatty acids.
