摘要：Xylooligosaccharides (XOS) have prebiotic potential when consumed as a part of diet and can be incorporated into many food products. They affect the host by selectively stimulating the growth of limited number of bacteria such as Bifidobacteria and Lactobacillus and hence improve the health. Thirty strains of lactic acid bacteria (LAB) were isolated from Bulgarian dry sausages – Lukanka. They were identified through standard techniques and sequenced for 16S ribosomal genes and were referred to the following types Lactobacillus plantarum, Lactobacillus brevis and Lactobacillus sakei. To investigate the utilization of xylo-oligosaccharides, modified media containing 2% xylo-oligosaccharides was used. The microbial growth on xylooligosaccharides was compared with such on glucose .The obtained results revealed that some of the identified strains can utilize XOS and glucose with similar efficiency.
