Abstract

This research aimed to isolate exopolysaccharides (EPS) producing Lactobacilli isolated fromsumbawa mare’s milk and its potential as prebiotics for modulating the growth of Bifidobacteriumbreve. Nine strains of Lactobacillus sp. were screened for their capabilities to produce EPS usingmodified MRS medium containing sucrose. Prebiotics potential of the EPS was verified by culturingB. breve JCM1273 in TOS medium containing EPS. The results showed that all strains ofLactobacillus sp. produced EPS on MRS sucrose medium and two strains (Lactobacillus SK3.1 andLactobacillus SK4) produced more EPS compared to the other strains tested. Bifidobacteriumbreve JCM1273 showed weak activity while in direct metabolism of EPS produced by Lactobacillussp. SK4 and its growth was enhanced on acid hydrolyzed EPS. Since this phenomenon mighthappened when the EPS exposed by the low pH during gastric passage, hence the EPS might be apotential source to be developed as prebiotics. Nevertheless, further investigation is necessary toevaluate the bifidogenic affects of EPS in Lactobacillus sp. SK4.

Abstract

The main aim of this study was to determine the potency of lactic acid bacteria (LAB) isolate 18A(Lactococcuslactisssplactis 1),isolated from the colon of Bali cattle to be used as a probiotic candidate. The study was started by confirmation tests of the isolate, including test for growth response in De Man Rogosa and Sharpe(MRS) brothmedium, test on catalase production, and Gram staining.Its probiotic potencywas tested by growing theisolate in MRS broth medium in low pH conditions (pH 2.3 and 4) and in MRS medium supplemented with various concentrations of sodium deoxycholatet (NaDC) (0.2 mM, 0.4 mM, and 0.6 mM). The results showed that isolate 18A was able to grow well in De Man Rogosa and Sharpebrothmediumunder anaerobic condition. In addition, the isolate was catalase negative and Gram positive, indicating that this isolate was confirmed as an LAB isolate. The isolate was resistant to low pH conditions (up to pH 2) and to high concentration of NaDC (up to 0.6 mM), indicating that this isolate has potential to be developed as a probiotic candidate. Further tests are still required to confirm its use asprobiotic.

Abstract

Bali cattle is an indigenous spesies in Bali, which pay great attention due to its uniqueness. Numerousarticles have been published on Bali cattle especially related to its disease, nutritional requirement forgrowth and domestication. Nevertherless, it was no any report has been published on the lactic acidbacteria (LAB) assosiated with the cattles raw milk and its potential used as probiotic. This work isaimed to identify LAB isolated from bali cattle raw milk and its resistance to secondary bile acid (sodiumdeoxy cholic), a prequisite in development of probiotic for human. The results revealed that based upon thehomology studies of the variable region I, II, and III sequences of the 16S rDNA showed that 44 out of 62isolates were closely related to Pediococcus acidilactici; 11 out of 62 isolats were closely related to Enterococusgallinarum, five out of 62 isolates were closely related to Lactococcus garvieae, while only one isolate was closely related to Lactobacillus plantarum and Weisella confusa. Some isolates showed resistant to 0.2-0.6mM deoxy cholic acid, which might be also resist in human gastrointestinal tract conditions. Based onthose finding, it can be concluded that the LAB associated with raw bali cattle milk were closey related toP. acidilactici, E. gallinarum, Lac. garvieae, Lb. plantarum and W. confusa, which different from thosecommonly LAB found in others cattle raw milk. Somes isolates were potential to be developed as probioticfrom human helath.

Abstract

A study was carried out to isolate and characterize lactic acid bacteria (LAB) from the Sumbawa mares milk The Isolation of LAB was conducted in Man Rogosa Sharpe (MRS) agar. The isolates were characterized by standard methods, such as Gram staining, cell morphology study and fermentation activities. The ability of the isolates to inhibit some pathogenic bacteria was studied by dual culture assay. Isolates showing the widest spectrum of inhibiting pathogenic bacteria were further identified using API 50 CHL. The results showed that Sumbawa mare milk was dominated by lactobacilli and weisella/leuconostoc. As many as 26 out 36 isolates belong to homofermentative lactobacilli and another 10 isolates belong to both heterofermentative lactobacilli and weissella or leuconostoc. Twenty four isolates inhibited the growth of Escherichia coli 25922, Shigela flexneri, Salmonella typhimurium, and Staphylococcus aureus 29213. Two promising isolates with the widest spectrum of inhibiting pathogenic bacteria, Lactobacillus sp. SKG34 and Lactobacillus sp. SKG49, were identified respectively as Lactobacillus rhamnosus SKG34 and Lactobacillus ramnosus SKG49. These two isolates were specific strains of the sumbawa mare milk and are very potential to be developed as probiotic for human.

Abstract

The objective of this research was to characterize Lactobacillus spp., isolated from milk of Etawagoats for local probiotic development. Total of 23 isolates Lactobacillus spp. were tested for resistance tolow pH conditions, high levels of natrium deoxy cholate, and modified gastric juice conditions. Besidesthat, those isolates were also tested to convert cholic acid (CA) into deoxycholic acid (DCA). Isolate thatshowed the most potential properties for local probiotic development was identified by 16S rDNA analysisusing following amplification of this sequence with primers of 27F and 520R). The results showed that 12isolates were found to be resistant to low pH conditions and to high level of NaDC (0.6 mM). Three of them(Lactobacillus spp. GMA46, Lactobacillus spp. GMA47 and Lactobacillus spp. GMA50) did not convertcholic acid into deoxy cholic acid, indicating that they are safe for human use. Lactobacillus spp. GMA46showed better performance in the gastric juice (a model of gastic and intestinal juice containing pepsin andpancreatin enzymes at pH 2, 3 and 4) simulation test. This GMA46 isolate was identified as L. caseiATCC 334 and L. paracasei subsp. tolerans strain NBRC 15906 with 100% similarity, in term of its 16srDNA nucleotide sequence. The results of this research indicate that Lactobacillus sp. GMA46 is anIndonesian potential probiotic strain, isolated from milk of etawa goats

Abstract

Kandidiasis merupakan infeksi yang disebabkan oleh kamir kelompok Candida, terutama C. albicans. Kamir ini bersifat oportunis, karena C. albicans dapat menunjukkan karakateristik patogenitasnya atau berubah menjadi pathogen bila terjadi perubahan-perubahan kondisi lingkungan di tempat-tempat dimana species kamir ini berasosiasi dengan mikrob lain pada inangnya. Perubahan-perubahan kondisi lingkungan ini umumnya menyebabkan terjadinya perubahan komposisi mikrobiota pada bagian-bagian tersebut, dan perubahan ini dapat bersifat lokal atau sistemik pada inangnya. Dalam kondisi normal, pertumbuhan C. albicans dikendalikan/dikontrol oleh kehadiran mikrob lain dengan komposisi seimbang yang ada disekitarnya. Bila terjadi ketidakseimbangan mikrobiota normal pada tempat-tempat tersebut, maka kondisi ini akan dimanfaatkan oleh C. albicans untuk tumbuh dan berkembang melampaui mikroba lain. Pertumbuhan berlebih C. albicans ini sering menimbulkan masalah atau menyebabkan infeksi/lesi. Pada inangnya, kamir ini sering berasosiasi pada mukosa rongga mulut, permukaan kulit, saluran pencernaan, serta alat reproduksi wanita (vagina), dan menyebabkan infeksi yang disebut dengan kandidiasis. Kasus kandidiasis terus mengalami peningkatan dalam beberapa tahun terakhir, yang disebabkan oleh munculnya kasus resistansi Candida spp., terhadap antifungi yang dipakai dalam pengobatan kandidiasis. Pemahaman menyeluruh terkait kandidiasis menjadi sangat penting dan diperlukan untuk membangun strategi potensial dalam penanggulangan kandidiasis. Oleh karena itu, dalam telaah pustaka ini dielaborasi berbagai topik penting terkait kandidiasis dan alternatif penanganannya. Semua informasi yang diperlukan diekstrak dari berbagai artikel terkait yang dipublikasikan di jurnal-junal ilmiah bereputasi. Beberapa aspek seperti mekanisme Candida spp., dalam menyebabkan infeksi, faktor-faktor predisposisi, permasalahan dalam terapi kandidiasis menggunakan agen antifungi, maupun terapi alternative (termasuk pendekatan biokontrol menggunakan probiotik potensial) dijabarkan secara komprehensif dalam telaah pustaka ini

Abstract

This research focused on the utilization of four different organic wastes, namely snake fruit, orange, cabbage, and tomato wastes, for the production of biogas. The main objectives were twofold: (1) to investigate the characteristics and biodegradability of these wastes, and (2) to evaluate their potential for anaerobic methane production. The experiment was conducted using 250 L bioreactors, with the four wastes serving as the primary raw materials. A starter culture of cattle dung was added, and the mixture was incubated for eight weeks. Regular sampling and analysis were carried out to assess water content, biodegradability, specific rate of volatile material reduction, and gas yield. The results showed that the water content of the four waste systems remained relatively consistent throughout the experiment. Biodegradability analysis revealed that all of the wastes were biodegradable, with varying levels of degradation ranging from 23.10 ± 2.89% to 59.84 ± 4.17%. Snake fruit waste exhibited the highest resistance to degradation, while tomato waste was the most easily degradable. Kinetic analysis indicated specific rates of volatile material reduction (µ) of 0.006 ± 0.0006 per day for the most resistant waste and 0.0170 ± 0.0021 per day for the least resistant waste. The incorporation of these four waste types in the biogas production process had a positive effect on gas formation. Therefore, these organic wastes hold promise as valuable resources for biogas production, addressing both the issue of waste accumulation and the energy crisis in an environmentally beneficial manner.
