“…Classified reference voucher specimens were deposited at the Herbarium of the Faculty of Pharmaceutical Sciences, Prince of Songkla University, Hat Yai, Songkhla, Thailand. The extract was obtained through a hot water extraction method [ 15 ] and filtered with 125-mm Whatman filter paper (Whatman Int. Ltd., Maidstone, UK) under vacuum at room temperature.…”

“…E. americana extract was partially purified using Saccharomyces cerevisiae BCC 12652 to remove reducing sugar [ 15 ]. The extract was sterilized by filtration through a 0.22-μm membrane, followed by precipitation twice by 80% ethanol at 4 °C for 12 h. The sample was centrifuged at 10,000× g for 20 min, at 4 °C to remove the supernatant, and the attained supernatant was completely dried.…”

“…There have been a number of studies on E. americana bulb extract for applications in food [ 13 , 14 ]. Furthermore, both the extract and oligosaccharide extract have been used as prebiotics to produce growth stimulation on beneficial bacteria, which resulted in an increase in the production of short chain fatty acids [ 15 ]. However, there are no reports available on the application of E. americana as a co-encapsulating agent in protecting probiotic bacteria against gastrointestinal conditions.…”

Microencapsulation using extrusion and emulsion techniques was prepared for Bifidobacterium longum protection against sequential exposure to simulated gastric and intestinal juices, refrigeration storage and heat treatment. Eleutherine americana was used as the co-encapsulating agent. Hydrolysis of E. americana by gastric and intestinal juices was also determined. E. americana and its oligosaccharide extract demonstrated their resistance to low pH and partial tolerance to human α-amylase. Microencapsulated B. longum with E. americana and oligosaccharide extract prepared by the extrusion technique survived better than that by the emulsion technique under adverse conditions. Survival of microencapsulated cells after exposure to the juices and refrigeration storage was higher than free cells at Weeks 2 and 4. In addition, the viability of microencapsulated cells was better than free cells at 65 °C for 15 min. This work suggested that microencapsulated B. longum with E. americana offers the effective delivery of probiotics to colon and maintains their survival in food products.

“…Установлено, что метаболический профиль фекалий при обогащении рациона кцФОС и длФОС в основном представлен уксусной и молочной кислотой с незначительным содержанием пропионовой и масляной (бутират). Максимальное образование уксусной кислоты происходит при метаболизме кцФОС (экстракта олигосахаридов) бифидобактериями и лактобациллами [50]. Метаболический профиль фекалий детей на грудном вскармливании включает молочную кислоту и ряд КЦЖК (уксусная, пропионовая, масляная и др.…”

Санкт-Петербургский государственный педиатрический медицинский университет, Российская Федерация В обзоре современной литературы обобщены результаты научных исследований о составе интестинальной микробиоты как у взрослого человека, так и у младенца. Показано, что вся интестинальная микробиота взрослого включает 395 филогенетически обособленных групп микроорганизмов, из которых 244 являются абсолютно новыми. На основании метода РНК-секвенирования генов выделены наиболее часто встречающиеся у европейцев энтеротипы. Продемонстрировано, что у взрослого индивидуума видовой состав интестинальной микробиоты уникален и стабилен, и что основой становления кишечного микробиома служит генетический фон макроорганизма. Освещены особенности формирования микробиоценоза на ранних этапах онтогенеза. Подчеркнуто, что преобладание «младенческих» видов бифидобактерий в составе интестинальной микробиоты у детей на естественном вскармливании обусловлено наличием в грудном молоке определенных питательных субстратов-олигосахаридов грудного молока, относящихся к природным пребиотикам. Обозначены критерии, которым должен соответствовать пищевой ингредиент, чтобы он мог быть отнесен к группе пребиотиков. Представлены новые экспериментальные и клинические данные о влиянии пребиотиков на разные уровни иммунологической защиты.

This study aimed to determine the survival and antibacterial activity of Lactobacillus plantarum TISTR1465 encapsulated with Eleutherine americana oligosaccharide extract. Capsules were stored at 4°C for 0, 2, and 4 weeks. The encapsulated cells were evaluated for their survival after sequential exposure to simulated gastric and intestinal juices, then evaluated in terms of their antibacterial activity. Survival of the encapsulated cells was higher than that of free cells at weeks 2 and 4. Highest levels of viable cells were observed with encapsulation in E. americana oligosaccharide extract. No surviving free cells were found in week 4. Yoghurt prepared with encapsulated cells showed less acidification than with free cells. Antibacterial activity of L. plantarum TISTR1465 before pH neutralisation against Clostridium perfringens ATCC13124, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Salmonella Typhimurium ATCC13311 was higher than after pH neutralisation. Encapsulation by extrusion enhanced antibacterial activity of the cells against enteropathogenic bacteria. The antibacterial activity of encapsulated cells against Gram-positive bacteria was higher than that against Gram-negative bacteria. Results indicates that L. plantarum TISTR1465 encapsulated with E. americana oligosaccharide extract showed potential for application as a functional food additive.
