Abstract
The effects of lactate and probiotic lactic acid bacteria (LAB) on intestinal fermentation were analyzed using a fecal batch culture. Lactate was efficiently metabolized to butyrate and propionate by butyrate-utilizing bacteria in fecal fermentation. Probiotic LAB could stimulate butyrate and propionate production through their lactate production in fecal fermentation. It was considered that 109 cfu/g or more of probiotic LAB would be required to stimulate butyrate and propionate production in the large intestine. Due to the low production of lactate, a larger number of heterofermentative LAB than homofermentative LAB would be required for this stimulation.
期刊介绍：
Bioscience of Microbiota, Food and Health (BMFH) is a peer-reviewed scientific journal with a specific area of focus: intestinal microbiota of human and animals, lactic acid bacteria (LAB) and food immunology and food function. BMFH contains Full papers, Notes, Reviews and Letters to the editor in all areas dealing with intestinal microbiota, LAB and food immunology and food function. BMFH takes a multidisciplinary approach and focuses on a broad spectrum of issues.
