Guar galactomannan was enzymatically hydrolyzed to obtain partially hydrolyzed guar gum which can be utilized as prebiotic source. In present study, growth of probiotics (Lactic Acid Bacteria strains) were studied with glucose, partially hydrolyzed guar gum and native guar gum. All the six strains were galactose &/or mannose positive using the API CHl 50 test. Almost all these strains showed an ability to assimilate partially hydrolyzed guar gum with respect to increase in optical density and viable cell count with concomitant decrease in the pH of the growth medium. Streptococcus thermophilus MD2 exhibited higher growth (7.78 log cfu/ml) while P. parvulus AI1 showed comparatively less growth (7.24 log cfu/ml) as compared to used lactobacillus and Weissella strains. Outcomes of the current study suggest that partially hydrolyzed guar can be considered as potential prebiotic compound that may further stimulate the growth of potentially probiotic bacteria or native gut microflora.
瓜尔胶经酶解得到部分水解瓜尔胶，可作为益生元来源。本研究以葡萄糖、部分水解瓜尔胶和天然瓜尔胶为碳源，研究了益生菌（乳酸菌菌株）的生长情况。所有 6 株菌均通过 API CHl 50 试验呈半乳糖和/或甘露糖阳性。几乎所有这些菌株都表现出能够部分水解瓜尔胶的能力，表现在光密度和活菌计数增加，同时生长培养基的 pH 值下降。嗜热链球菌 MD2 的生长情况更好（7.78 log cfu/ml），而与使用的乳杆菌和魏斯氏菌菌株相比，副干酪乳杆菌 AI1 的生长情况相对较差（7.24 log cfu/ml）。本研究结果表明，部分水解瓜尔胶可作为潜在的益生元化合物，进一步刺激潜在益生菌或天然肠道菌群的生长。
