Probiotics are one of the most beneficial elements in human health. Several studies have confirmed the health benefits of probiotics. The consumption of fermented vegetables is widespread worldwide and represents an important component of the human diet for a growing global population. In recent years, consumers have become more aware of the relationship between food and health, which has led to an increase in interest in functional foods. The global market for probiotic foods is growing rapidly due to the increasing consumer awareness. Although leafy vegetables are well-endowed with bacteria, including potentially probiotic strains of Lactobacillus, so far, plant-derived products have only been considered as carriers of probiotic cultures. This study aimed to produce probiotic garden cress using Bifidobacterium bifidum and to investigate its nutritional value, biocontrol, and growth rate and this is a great approach due to the increase in vegetarianism, lactose intolerance and people allergic to dairy products. Bifidobacterium bifidum (bb12) was inoculated into sterile cress seeds and the probiotic plant culture was done on days 0 and 3 after harvesting, in a TOS medium containing Mupirocin (MUP) antibiotic. The chemical properties (such as pH, acidity, and dry matter) of both samples were determined and the comparison of growth rate, fat content, vitamin C, and organoleptic properties was done. Bacterial survival in simulated gastrointestinal (SGI) conditions and its antifungal effect on Rhizoctonia solani were also analyzed. The number of bacteria on days 0 and 3 was [Formula: see text] and 2.3 [Formula: see text] Colony Forming Unit/gram (CFU/g) respectively, which confirms the probiotic nature of the product ([Formula: see text] bacteria). Also, significant difference ([Formula: see text]0.05) was observed in the physicochemical parameters. Bacterial viability was reported as 6.3 [Formula: see text] CFU/g in simulated gastric condition and as [Formula: see text] CFU/g in simulated intestine condition, and the antifungal effect of Bifidobacterium on R. solani was 15%. It can be concluded that production of other probiotic vegetables might be possible and that the plant based probiotics can be used to support the growth of human intestinal bacteria and also maintain high cell viability during storage.
益生菌是人类健康中最有益的元素之一。多项研究已证实益生菌对健康有益。发酵蔬菜的食用在全球范围内广泛存在,并且对于不断增长的全球人口而言,是人类饮食的重要组成部分。近年来,消费者愈发意识到食物与健康之间的关系,这导致对功能性食品的兴趣增加。由于消费者意识的提高,全球益生菌食品市场正在迅速增长。尽管绿叶蔬菜富含细菌,包括潜在的益生菌乳酸杆菌菌株,但到目前为止,植物源产品仅被视为益生菌培养物的载体。本研究旨在利用两歧双歧杆菌生产益生菌水田芥,并研究其营养价值、生物防治和生长速率,鉴于素食主义、乳糖不耐受以及对乳制品过敏的人群增多,这是一种很好的方法。将两歧双歧杆菌(bb12)接种到无菌水田芥种子中,并在收获后的第0天和第3天,于含有莫匹罗星(MUP)抗生素的TOS培养基中进行益生菌植物培养。测定了两个样品的化学性质(如pH值、酸度和干物质),并对生长速率、脂肪含量、维生素C和感官特性进行了比较。还分析了在模拟胃肠道(SGI)条件下细菌的存活情况及其对立枯丝核菌的抗真菌作用。第0天和第3天的细菌数量分别为[公式:见原文]和2.3[公式:见原文]菌落形成单位/克(CFU/g),这证实了该产品的益生菌性质([公式:见原文]细菌)。此外,在理化参数方面观察到显著差异([公式:见原文]<0.05)。在模拟胃部条件下,细菌活力报告为6.3[公式:见原文]CFU/g,在模拟肠道条件下为[公式:见原文]CFU/g,双歧杆菌对立枯丝核菌的抗真菌作用为15%。可以得出结论,生产其他益生菌蔬菜可能是可行的,并且基于植物的益生菌可用于支持人类肠道细菌的生长,并在储存期间保持较高的细胞活力。
