<abstract> <p>The probiotic potential of lactic acid bacteria (LAB) isolated from Thai traditional fermented food was investigated. Forty-two samples were collected from four markets in Phra Nakhon Si Ayutthaya Province. Out of 50 isolated LAB, 6 (a3, f4, f8, K1, K4 and K9) obtained from pla-ra and bamboo shoot pickle samples showed high tolerance to gastrointestinal tract conditions. These isolates were selected to identify and characterize their probiotic properties. Isolate a3 was identified as <italic>Weissella thailandensis</italic>, isolates f4 and f8 were identified as belonging to <italic>Enterococcus thailandicus</italic> and isolates K1, K4 and K9 were determined as <italic>Limosilactobacillus fermentum</italic>. All six LAB exhibited high autoaggregation ability (93.40–95.01%), while <italic>W. thailandensis</italic> isolate a3 showed potential for coaggregation in almost all the pathogenic bacteria tested. Cell-free supernatant (CFS) obtained from all isolates did not inhibit <italic>Staphylococcus aureus</italic>. CFS derived from <italic>L. fermentum</italic> isolate K4 showed the most efficient antimicrobial activity, in particular against Gram-negative bacteria, while <italic>L. fermentum</italic> isolate K4 presented high surface hydrophobicity in the presence of xylene and n-hexane. All LAB isolates were found to be resistant to clindamycin and nalidixic acid, whereas <italic>E. thailandicus</italic> isolate f8 exhibited resistance to most of the antibiotics tested. <italic>L. fermentum</italic> isolate K4 showed promise as a suitable probiotic candidate for future applications in the food industry due to tolerance to gastrointestinal tract conditions with high surface hydrophobicity and inhibited most of the pathogens tested.</p> </abstract>

Abstract. Yanti AH, Setyawati TR, Kurniatuhadi R. 2020. Isolation and characterization of lactic acid bacteria from fecal pellets, coelomic fluid, and gastrointestinal tract of Nypa worm (Namalycastis rhodochorde) from West Kalimantan, Indonesia. Biodiversitas 21: 4726-4731. Lactic acid bacteria isolated from the intestinal tract as probiotic could be beneficial because they could trigger the growth of the host by enhancing digestibility, increasing their immune system, and inhibiting pathogenic bacteria through the enzymatic process or metabolites production. The purposes of this study were to identify and characterize lactic acid bacteria from fecal pellets, coelomic fluid, and gastrointestinal tract of Nypa worm (Namalycastis rhodochorde). Bacterial isolation was carried out by the pour plate method on de Mann Rogosa Sharp Agar (MRSA). Lactic Acid Bacteria (LAB) isolates were purified and then physiologically characterized by some biochemical tests. Cellulolytic activities were carried out by detecting a clear zone formation on CMC-congo Red Agar. There were 20 isolates of lactic acid bacteria from fecal pellets, coelom fluid, and gastrointestinal tract of nypa worm. Ten isolates (50%) had cellulolytic activity on CMC-phenol red agar. Eight isolates were closely related to the genus Lactobacillus, while two isolates were closely related to the genus Bacillus. These cellulolytic bacteria could be developed further as probiotic in Nypa worm feed.

The gastrointestinal tract of human body is considered as an ecosystem which had been developed physiologically and microbiologically. The probiotic organisms (lactic acid bacteria) are one of the most important groups present in the gastrointestinal tract. A good number of Lactobacillus species, Bifidobacterium species, Saccharomyces boulardii and some other microbes are now used as probiotic strains. These probiotic organisms are marketed as health care products, functional foods or food supplements. The details of clinical, therapeutic applications and safety aspects of probiotics are discussed.

INTRODUCTION: Dadiah is a fermented buffalo milk product containing many potential lactic acid bacteria as probiotics. Lactic acid bacteria and their derivative products can prevent the onset of various diseases such as spur health and heart work, good food to increase stamina and endurance, prevent colorectal cancer, and improve intestinal microflora. AIM: This study aims to determine the influence of probiotic on dadiah as fermented buffalo milk products for breastfeeding women with normal bacterial flora of the gastrointestinal tract. METHODS: The study was conducted on 28 breastfeeding mothers who were divided into two groups with the same proportion, i.e., mothers who received dadiah ice cream and not. Interventions were performed for 1 month and analysis was performed on an infant’s feces. DNA isolated from feces and Lactobacillus plantarum concentrations were analyzed using real-time polymerase chain reaction. The standard curve designed to get the concentration of bacteria appropriately. Data analysis used SPSS version 20.0. Numerical data were analyzed by used unpaired t-test and paired t-test. A p < 0.05 was considered statistically significant. RESULTS: The results showed that the mean intestinal microflora from the infant before the dadiah ice cream given was 4.2 × 107 CFU/g and after the dadiah ice cream was 8.6 × 108 CFU/g (p < 0.05) while in the control group, the mean L. plantarum intestinal infants before administered whey ice cream is 2.6 × 107 CFU/g and thereafter 1.3 × 107 CFU/g (p > 0.05). CONCLUSION: Based on the results of this study, it can be concluded that there is an increase in L. plantarum concentration after the provision of dadiah ice cream in breastfeeding mothers.
