"Ruminants are herbivorous mammals that have special digestive tract, rumen, where digestion of cellulose and polysaccharides can be carried out by rumen microorganisms. Methanogenic bacteria in the rumen using H2 compounds results from anaerobic fermentation of carbohydrates to form methane. Methane production in the rumen is an energetically wasteful process, since the feed intake will be converted to methane and eructated as gas (Bunthoen, 2007). Rumen protozoa have a potential role in the process of digestion and breakdown of organic material. Hydrogen (H2) as one of the protozoa fermentation products are used by methanogenic bacteria to form methane. This causing methanogenic bacteria often found living attached to the surface of protozoa to keep a constant supply of hydrogen. The purpose of this study is to enumerate the number of methanogenic bacteria and protozoa with different diet and after the addition of probiotic Lactobacillus plantarum TSD-10 in vitro. This report consist of two parts, which are (1) Effect of Feeding Composition on Total Methanogenic Bacteria and Protozoa Rumen, and (2) Influence of Probiotic Lactobacillus plantarum TSD-10 on Total Methanogenic Bacteria and Protozoa In Vitro. The research was conducted at the Laboratory of Industrial Microbiology, Research Centre of Biotechnology? Indonesian Institute of Sciences (LIPI), Cibinong Bogor, from September 2008 ? May 2009. The treatment are diet A with ratio of grass : concentrate (30 : 70) and diet B with ratio of grass : concentrate (70 : 30). The probiotic L. plantarum TSD-10 dose are 0%, 5%, 10% and 15% v/v. The number of methanogenic bacteria obtained from diet A ranges between (0,74 ? 0,89) x 107 cfu/ml, whereas in diet B ranged from (1,71 ? 2,58) x 107 cfu/ml. Methanogenic bacteria average on feed B ((2,19 ± 0,44) x 107 cfu/ml) higher than the feed A ((0,82 ± 0,07) x 107 cfu/ml). Based on the Analysis of Variance (ANOVA), different composition of diet A and B, significantly affect the number of methanogenic bacteria ( 5%), with the best diet composition in suppressing the growth of methanogenic bacteria is diet A. The number of methanogenic bacteria in diet B are higher since the value of a more alkaline pH (8). According to Mirzaei-Aghsaghali et al. (2008), methanogenic bacteria are sensitive to changes in pH. Decrease in pH value will decrease the number of methanogenic bacteria and cause less methane gas produced. The low number of methanogenic bacteria on diet A, can also be caused by the ratio of acetate : propionate obtained lower than in diet B, and it also causes a lower pH of the diet A (Lana et al., 1998). The ANOVA showed the methanogenic bacteria average between diet A and B in the morning and afternoon sampling significantly different between treatments ( 5%), with the best treatment in suppressing methanogenic bacteria from each sampling were diet A. Increased methanogenic bacteria after feeding may be associated with the presence of protozoa in the rumen cilliata that serves as a producer of hydrogen and bacterial attachment to methanogen. Composition diet B low in fiber and high in starch are preferred by the protozoan (Leedle and Greening, 1988). The number of protozoa obtained from the diet A ranges between (1,93 ? 3,95) x 105 cells/ml, whereas the diet B ranged from (2,81 ? 4,35) x 105 cells/ ml. Protozoa average on diet B ((3,76 ± 0,83) x 105 cells/ml) higher than the diet A ((3,08 ± 1,04) x 105 cells/ml). Based on the ANOVA, differences composition diet A and B, not significantly different between treatments (5%). Diet B with a higher pH value causes no influential ration of protozoa, which does not cause a decrease in the number of protozoa. The ANOVA indicate that the average range of protozoa between diet A and B are significantly different (5%) in the morning sampling, with the best treatment in suppressing the number of protozoa are diet A. The afternoon sampling, ANOVA showed that the treatment was not significantly different (5%). Protozoa observed in treatment diet A and B are families of, Ophryoscolecidae, Isotrichidae and Blepharocorythidae. Most number obtained from each diet is Ophryoscolecidae, while the less is Blepharocorythidae. This is due to Ophryoscolecidae a part of the Order Entodiniomorphida who compiled most of rumen cilliata. In the contrary, Family Isotrichidae and Blepharocorythidae are part of the order Trichostomatida which is rarely found in rumen (Ogimoto and Imai, 1981). Decreasing in the number of methanogenic bacteria in the diet B (56,8%) higher than diet A (29,8%), while the decrease in the number of protozoa in the diet B (64,9%) higher than diet A (62,7% ). Diet B with a higher concentrate composition can provide a change in the pattern of rumen fermentation. These changes make the environment less suitable for methanogenic bacterial growth. One of the unfavorable change is a reduction of rumen pH values (Moss et al., 2000). On the addition of probiotics in vitro, the ANOVA showed the range of the number of methanogenic bacteria was not significantly different ( 5%) on the variations of diet A and B but significantly different (5%) on the number of protozoa, with the best in suppressing the growth of protozoa are diet A. Variations doses of probiotic significantly different (5%) on the number of methanogenic bacteria and protozoa, with the best dose 5% v/v to suppress methanogenic bacteria and 15% v/v to suppress protozoa in vitro. Feed Digestibility Coefficient (FDC) shows the FDC from 27,99 ? 31,95%, while the diet B ranged from 25,85 to 31,3%. In diet A, the value FDC obtained tended to increase (8,5%) along with increasing concentration of probiotic L. plantarum TSD-10. Increasing FDC value expected to suppress the growth of methanogenic bacteria by altering the rumen fermentation pattern which results in volatile fatty acids produced. Diet A shows the value of higher acetate than propionate, because diet A high on fiber that will support the growth of the acetate-producing bacteria species, diet B rich in starch that supports the growth of propionic-producing bacteria species, and marked by increasing propionate than acetate (France and Dijkstra, 2005)."

ABSTRACTDecreased defecation frequency DDF has a correlation between host, diet, and environment. Sedentary lifestyle is risk factors of DDF in factory and office workers, and often accompanied by hard stool consistency and flatulence. Previous study showed that probiotics improve DDF through SCFA production that stimulates bowel motility through few mechanisms. This is a double blind, randomized controlled trial was conducted among office and labour worker who experienced DDF. They were randomly allocated to receive 6 weeks probiotic supplementation of strain L.plantarum KCTC 10782 BP, S.thermophilus KCTC 11870 BP, B.bifidum KCTC 12199 BP 4x109 CFU day and 1920 mg FOS day or control group with 1920 mg FOS day only. Results showed most subjects in this study were women, with mean age 29.6 and 25.2 years for the intervention group and control group, had excess nutritional status, less exercise habits, had functional constipation, defecation frequency 3 times week, and low levels of butyric acid stool. Mean difference in changes of defecation frequency, butyric acid stool, flatulence score, and Bristol score distribution did not differ between two groups even after adjustment for age and baseline value of fiber intake. It concluded that a mixture of probiotics strain in this study did not significantly improve DDF compared to control"

Background: Laparotomy is a surgical procedure that affects gastrointestinal motility. Research by Cihoric et al showed that 12.5% ​​of post-laparotomy patients experienced complications of gastrointestinal dysfunction. Dysfunction in gastrointestinal motility is a frequent complication of abdominal surgical procedures. Out of 100 patients with digestive laparotomy surgery, it was found that as many as 40% of patients in the ICU experienced an increase in gastric residual volume in postoperative digestive laparotomy patients. Supplementation with Lactobaciillus acidophilus is known to increase gastric motility.

Aim: This study aims to determine the effect of the relationship between administration of Lactobacillus acidophillus probiotics and GRV.

Methods: The study design used was an experimental or double-blind randomized clinical trial. A total of 55 subjects who followed the randomization, 54 subjects who would undergo gastrointestinal laparotomy were included in the study, 1 subject dropped out due to sepsis. Research subjects were given probiotic capsules Lactobacillus acidophilus 109 (probiotic group) or given lactose capsules (placebo group) for 3 days before surgery. GRV levels were measured 2 days after the procedure.

Results: Of the 54 subjects with 27 subjects in each group, they followed the research to completion. On the first day (24 hours), the 24-hour GRV with the administration of probiotics and the control group showed insignificant results (p value 0.669). On day 2 (48 hours), GRV 48 hours with probiotic administration and the control group showed insignificant results (p value 1,000). Results that were not significant at GRV 24 hours and 48 hours could be influenced by confounding factors, geriatrics, history of neurological disorders, obesity, history of vasopressor use, history of consumption of opioids, hypercapnia and hyperglycemia while in the ICU.

Conclusion: Administration of Lactobacillus Acidophilus probiotics with GRV had no association effect compared to placebo."

Background: Laparotomy is a surgical technique to open access to the peritoneal cavity by forming an open incision in the abdominal area. Mucosal injury due to surgical trauma can disrupt epithelial homeostasis, impair the microbiome ecosystem, increase the production of proinflammatory cytokines and relating to the incidence of postoperative complications. Lactobacillus acidophillus probiotic administration improve the intestinal barrier function, maintains the microbiome ecosystem and potentially modulate immune responses. However, there has been no research on the impact of Lactobacillus acidophilus administration on C-Reactive Protein (CRP) levels after gastrointestinal laparotomy as a marker of inflammation.

Objective: This study aimed to determine the impact of Lactobacillus acidophilus on CRP levels after gastrointestinal laparotomy

Methods: This study is a randomized controlled trial. Fifty six subjects scheduled gastrointestinal laparotomy surgery were enrolled. Subjects received Lactobacillus acidophilus 109 probiotic capsules (probiotic group) or lactose capsules (placebo group) for 3 days before surgery. CRP levels were measured 3 days before the procedure and 3 days after the procedure.

Results: Fifty-six subjects with 28 subjects in each group completed the study. On the third postoperative day, probiotics effectively suppressed the elevating inflammatory response with the final CRP value in the probiotic group lower than the placebo group (median probiotic 89.65 mg/L vs. placebo 204 mg/L, p < 0.001). Elevated CRP values ​​were lower in the probiotic group than in the placebo group (median probiotic 84.8 mg/L vs. placebo 187.6 mg/L, p < 0.001). There was a significant side effects (nausea, diarrhea, vomiting, and bloating) in the probiotic group during study (p = 0.04).

Conclusions: Preoperative probiotic administration significantly reduced elevated CRP in patients After Undergoing Gastrointestinal Laporotomy."

"Telah dilakukan penelitian mengenai uji in vivo campuran bakteri kandidat probiotik terhadap pertumbuhan dan sintasan ikan mas (Cyprinus carpio L.). Uji in vivo dilakukan dengan memberikan campuran Lactobacillus plantarum, Bacillus pumilus, Bacillus sp. 41kF2b, dan Bacillus sp. YAS1 ke dalam pelet pakan ikan komersial yang diberikan sebagai pakan ikan mas. Pemberian pakan tersebut dilakukan selama 20 hari dan dilanjutkan dengan uji tantang terhadap bakteri patogen Aeromonas hydrophila. Uji tantang dilakukan dengan merendam ikan mas pada konsentrasi A. hydrophila 108 CFU/ml selama 10 menit. Ikan mas kemudian dipindahkan dan dipelihara dalam akuarium bersih selama 7 hari dengan diberi pakan tanpa bakteri kandidat probiotik. Pertumbuhan yang lebih cepat dan sintasan yang lebih tinggi dapat dijadikan parameter untuk mengetahui apakah campuran bakteri tersebut dapat berperan sebagai kandidat probiotik. Setelah 20 hari pemberian pakan dengan bakteri kandidat probiotik terdapat pertambahan biomassa ikan mas 5,22% lebih tinggi dibandingkan biomassa ikan mas kontrol. Pemberian bakteri kandidat probiotik pada ikan mas selama 20 hari memberikan pengaruh nyata (P<0,05) terhadap pertambahan biomassa ikan mas. Uji tantang terhadap A. hydrophila menunjukkan sintasan (kelulusan hidup) ikan mas perlakuan sebesar 97,5%, sedangkan kontrol sebesar 60%."

"Sampai saat ini limbah cair tahu (LCT) belum banyak dimanfaatkan. Telah diteliti di dalam LCT masih terkandung senyawa organik seperti karbohidrat, protein, dan senyawa golongan isoflavonoid yang dapat dimanfaatkan lebih lanjut. Jenis isoflavon yang dominan dalam kedelai adalah genistein dan daidzein yang berperan penting terhadap kesehatan manusia. Penelitian ini bertujuan untuk mengisolasi mikroba yang terdapat dalam LCT, yang diduga mampu mentransformasikan isoflavon. Dari hasil isolasi mikroba pada LCT, diperoleh 3 jenis mikroba yaitu mikroba bulat putih inti (BPI), mikroba bulat kuning muda (BKM), dan mikroba bulat kuning (BK).
