摘要

对从牧草中分离的712株乳酸菌进行了研究,研究了它们对乳酸菌中乳酸菌的发酵能力。只有16株菌株利用静脉素,其中8株也发酵菊粉。经鉴定为副干酪乳杆菌亚种。paracasei,注射。杆菌,注射。短链球菌和戊糖球球菌。在哺乳动物中。paracasei无性系种群。Paracasei,所有菌株都有阳性结果,而其他阳性菌株在各自的物种中具有独特的性质。除了两种情况外,所有情况下(物种Lact的菌株)。植物),静脉素比菊粉发酵更强烈,从较低的pH和较高的乳酸浓度可以看出。根据本研究结果,在青贮前用能发酵果聚糖的活性菌株接种低糖草是值得的。

Fermentation of fructans by epiphytic lactic acid bacteria.

A total of 712 strains of lactic acid bacteria isolated from forage grasses were studied for their ability to ferment fructans of phlein- as well as inulin-type. Only 16 strains utilized phlein and eight of these also fermented inulin. They were identified as Lactobacillus paracasei subsp. paracasei, Lact. plantarum, Lact. brevis and Pediococcus pentosaceus. In the species Lact. paracasei subsp. paracasei, all strains gave positive results, whereas the other positive strains possessed unique properties within their own species. In all but two cases (strains of the species Lact. plantarum), the phlein was more intensively fermented than the inulin, as indicated by a lower pH and a higher lactic acid concentration. On the basis of the outcome of this study it seems worthwhile to inoculate grasses of low sugar content before ensiling with an active strain that can ferment fructans.
