Abstract

Fermented bamboo shoots such as Soibum, Soidon, Eup, Hirring, Hecche and Ekung etc. are non-salted acidic products obtained by natural fermentation predominantly with lactic acid bacteria (LAB). In this study, we have characterized 11-representative LAB that includes, Lactobacillus sp. (n=2), Lactobacillus plantarum (n=3), and one each of Lactobacillus fermentum, Lactococcus sp., Lactobacillus brevis, Lactobacillus curvatus, Leuconostoc sp. and Lactobacillus xylosus. Subsequently, these cultures were studied for their technological and functional properties. Different isolates exhibited variation in their activities. L. brevis showed maximum phytic acid degradation ability (19.33 U ml−1). L. xylosus had highest protease activity (64.2 nmol/ml) and also exhibited lipolytic activity. In addition, degree of cell hydrophobicity among these cultures ranged between 12.5 and 93.48 % with L. plantarum (SM2) showing highest degree of activity. Lactobacillus plantarum was the most common species found in the product studied. Results indicated that most of the LABs showed putative probiotic as well as antagonistic properties against the selected pathogenic bacteria. Characteristic aroma, flavour and texture in the fermented bamboo shoot products could be attributed to presence of these new LAB isolates.
