| 1 | Effect of probiotic Lactobacillus plantarum Dad-13 powder consumption on the gut microbiota and intestinal health of overweight adults显示文摘BACKGROUND Shifting on lifestyle,diet,and physical activity contributed on increasing number of obese people around the world.Multiple factors influence the development of obesity.Some research suggested that gut microbiota(GM)plays an important role in nutrient absorption and energy regulation of individuals,thus affecting their nutritional status.Report of Indonesia Basic Health Research showed that the prevalence of obesity in every province tended to increase.Although the root cause of obesity is excessive calorie intake compared with expenditure,the differences in gut microbial ecology between healthy and obese humans may affect energy homeostasis.GM affect body weight,especially obesity.Probiotics that are consumed while alive and able to colonize in the intestine are expected to increase the population of good bacteria,especially Bifidobacteria and Lactobacilli,and suppress pathogens such as Enterobacteriaceae and Staphylococcus.The strain of L.plantarum Dad-13 has been demonstrated to survive and colonize in the gastrointestinal tract of healthy Indonesian adults who consume fermented milk containing L.plantarum Dad-13.The consumption of probiotic L.plantarum Dad-13 powder decreased E.coli and non-E.coli coliform bacteria in school-aged children in Indonesia.L.plantarum is a dominant bacterium in the average Indonesian’s GM.For this reason,this bacterium is probably a more suitable probiotic for Indonesians.AIM To determine the effect of the consumption of indigenous probiotic Lactobacillus plantarum Dad-13 powder in overweight adults in Yogyakarta(Indonesia).METHODS Sixty overweight volunteers with a body mass index(BMI)equal to or greater than 25 consume indigenous probiotic powder L.plantarum Dad-13(2×109 CFU/gram/sachet)for 90 d.The study was a randomized,double-blind,placebocontrolled study.The volunteers filled in a diary on a daily basis,which consisted of questions on study product intake(only during ingestion period),other food intake,number of bowel movements,fecal quality(consistency and color),any medications received,and any symptom of discomfort,such as diarrhea,constipation,vomiting,gassing,sensation of illness,etc.Fecal samples and the subjects’diaries were collected on the morning of day 10+1,which was marked as the end of the baseline period and the start of the ingestion period.During the ingestion period(from day 11 to day 101),several parameters to measure and analyze the results included body weight and height(once a month),the lipid profile,GM analysis using MiSeq,short-chain fatty acid(SCFA)analysis using gas chromatography,and the measurement of fecal pH using a pH meter.RESULTS The consumption of indigenous probiotic powder L.plantarum Dad-13 caused the average body weight and BMI of the probiotic group to decrease from 84.54±17.64 kg to 83.14±14.71 kg and 33.10±6.15 kg/m2 to 32.57±5.01 kg/m2,respectively.No significant reduction of body weight and BMI in the placebo group was observed.An analysis of the microbiota showed that the number of Bacteroidetes,specifically Prevotella,increased significantly,while that of Firmicutes significantly decreased.No significant change in lipid profile in both groups was found.Also,no significant change in SCFAs(e.g.,butyrate,propionate,acetic acid)and pH level was found after the consumption of the probiotic.CONCLUSION No significant differences in pH before and after ingestion were observed in both the probiotic and placebo groups as well as in the lipid profile of both cholesterol and triglyceride,high-density lipoprotein(HDL),low-density lipoprotein(LDL),and the LDL/HDL ratio.In addition,no significant changes in the concentration of SCFAs(e.g.,acetic acid,propionate,and butyrate)were found after consumption.Interestingly,a significant decrease in body weight and BMI(P<0.05)was determined in the treatment group.An analysis of GM shows that L.plantarum Dad-13 caused the Firmicutes population to decrease and the Bacteroidetes population(especially Prevotella)to increase. | Endang Sutriswati Rahayu Mariyatun Mariyatun Nancy Eka Putri Manurung Pratama Nur Hasan Phatthanaphong Therdtatha Riko Mishima Husnita Komalasari Nurul Ain Mahfuzah Fathyah Hanum Pamungkaningtyas Wahyu Krisna Yoga Dina Aulia Nurfiana Stefanie Yolanda Liwan Mohammad Juffrie Agung Endro Nugroho Tyas Utami | 2021 | World Journal of Gastroenterology2021，27，1： | 6 |
| 2 | Gut microbiota profile in healthy Indonesians显示文摘BACKGROUND Recently, gut microbiota has been associated with various diseases other than intestinal disease. Thus, there has been rapid growth in the study of gut microbiota. Considering the numerous factors influencing gut microbiota such as age, diet, etc., area-based research is required. Indonesia has numerous different tribes and each of these tribes have different lifestyles. Hence, it is expected that each tribe has a specific gut microbiota. A deeper insight into the composition of gut microbiota can be used to determine the condition of gut microbiota in Indonesians and to consider which treatment may be suitable and effective to improve health status.AIM To investigate the gut microbiota of Indonesian subjects represented by Javanese and Balinese tribes by analyzing fecal samples.METHODS Fecal samples were collected from a total of 80 individuals with 20 in each of the young groups ranging from 25-45 years and the elderly group aged 70 years or more from two different regions, Yogyakarta and Bali. Fecal sample collection was performed at the end of the assessment period(day 14 ± 1 d) during which time the subjects were not allowed to consume probiotic or antibiotic products.The quantification of various Clostridium subgroups, Lactobacillus subgroups,Enterococcus, Streptococcus, Staphylococcus, Bacteroides fragilis group and Prevotella,Bifidobacterium and Atopobium cluster, Enterobacteriaceae and Pseudomonas was performed using the Yakult intestinal flora-scan(YIF-SCAN).RESULTS The bacterial population in younger subjects' feces was higher than that in the elderly population, with a total of approximately 10.0 – 10.6 log10 bacterial cells/g feces. The most abundant bacteria in all groups were Clostridium, followed by Prevotella, Atopobium, Bifidobacterium and Bacteroides. In the elderly, an increase in Enterobacteriaceae, Coliform and Escherichia coli was found. In terms of bacterial counts in Yogyakarta, total bacteria, Clostridium coccoides(C. coccoides) group,Bifidobacterium, Prevotella, Lactobacillus plantarum subgroup, and Streptococcus were significantly higher(P < 0.05) in younger than elderly subjects, while the Lactobacillus gasseri subgroup, Lactobacillus casei subgroup, and Lactobacillus reuteri subgroup counts were significantly lower(P < 0.05) in younger subjects. In Balinese subjects, total bacteria, C. coccoides group, Clostridium leptum subgroup,Bacteroides fragilis group, and Prevotella were significantly higher(P < 0.05) in younger compared to elderly individuals, while the Lactobacillus ruminis subgroup, and Enterobacteriaceae were significantly lower(P < 0.05) in younger subjects. The results also revealed that, besides the C. coccoides group and Clostridium leptum group being the most abundant gut microbiota in both Yogyakarta and Balinese people, the latter was indicated by a higher Clostridium perfringens count, which was almost 10 times that of Yogyakarta subjects. This may be a response to different lifestyles in the different tribes; however, this phenomenon requires further extensive study.CONCLUSION Bacterial populations were higher in younger than in elderly subjects. Most abundant bacterial groups were Clostridium, Prevotella, Atopobium, Bifidobacterium,and Bacteroides. The level of Clostridium perfringens in Yogyakarta subjects was lower than that in Balinese subjects. | Endang Sutriswati Rahayu Tyas Utami Mariyatun Mariyatun Pratama Nur Hasan Rafli Zulfa Kamil Ryan Haryo Setyawan Fathyah Hanum Pamungkaningtyas IskANDar Azmy Harahap Devin Varian Wiryohanjoyo Putrika Citta Pramesi Muhammad Nur Cahyanto I Nengah Sujaya Mohammad Juffrie | 2019 | World Journal of Gastroenterology2019，25，12： | 6 |

| 9 | Functional trait profiles and diversity of trees regenerating in disturbed tropical forests and agroforests in Indonesia显示文摘A main question in restoration of degraded forests and forest landscapes recovering from logging and fire is what to expect from natural regeneration through surviving propagules in the soil or seed sources and associated dispersal agents from the surrounding landscape mosaic,as alternative to tree planting.Tree diversity in secondary forests may be high,but based on newcomer species of low wood density and long-distance,abiotic dispersal modes.We compiled and analyzed three pairs of case studies(totaling 815 plots and 11.8 ha)of secondary forests recovering from logging,fire and conversion to agroforest in Sumatra and Kalimantan(Indonesia)on mineral soils.Data on tree species diversity,wood density frequency distribution(indicative of successional status)and dispersal modes were compared with those of less disturbed comparator forests in the same landscapes.Relatively undisturbed lowland dipterocarp forest in Kalimantan had close to 200 species of trees(>10 cm diameter)at a 1-ha sample scale(and 450 at a 10-ha scale).After repeated fires a sample area of 2 ha was needed to reach the same species richness.Regulation-based logging had little impact on tree species richness.In rubber agroforest with low-intensity management beyond rubber planting,50 tree species were found at a 1-ha scale and close to 100 species in 3 ha.The Kalimantan forest after repeated fires had a markedly higher fraction of lowwood-density trees(40%),but otherwise,all forests sampled were similar in overall wood density profiles.Selectively logged forest managed by a local community(village forest)and rubber agroforest in Sumatra contained larger fractions of heavy-wood-density trees.The majority of trees(50%–70%)had birds,bats and primates as dispersal agents in all sites.Selectively logged forests had higher fractions of autochorous species(15%)compared to other sites.Anemochorous(wind-dispersed)species,especially Macaranga lowii,were most common(20%)in lowland dipterocarp forest.Comparison between secondary forests and agroforests showed the influence of farmer selection regarding what is allowed to grow beyond the pole stage.Wood density and seed dispersal profiles can be used as degradation indicators of species assemblages across various disturbance levels and types,as they reflect the habitat quality of the surrounding landscape mosaics. | Subekti Rahayu Sidiq Pambudi Dikdik Permadi Hesti L.Tata Endri Martini Saida Rasnovi Hani S.Nuroniah Roeland Kindt Mohamad Nugraha Sonya Dewi Meine van Noordwijk | 2022 | Forest Ecosystems2022，9，3： | 1 |
