Abstract

The aim of this experiment was to identify isolates obtained from feces of Indonesian infants and to evaluate their capability as probiotics. Identification of isolates was carried out based on morphology, physiology and biochemical identifications, and molecular identification based on 16S rRNA sequence. Morphological and physiological identification was carried out based on Gram staining, shape, motility, spore formation and catalase production. Biochemical identifications based on production of CO2 and NH3 from glucose, the ability to grow on different temperature (10 and 45°C) and pH (4.4 and 9.6), and different salt concentration (6.5 and 18%). Probiotics capability of isolates was assayed on the ability to grow on low pH (pH 2.0), on different bile salts concentration (0.3; 0.5; 1.0 and 1.5%), the capacity to grow on media with inulin as the only carbon source, and in vitro adhesion ability on porcine mucin. Morphological, physiological and biochemical identification suggest that all of isolates belong to lactic acid bacteria. Further molecular identification of five isolates showedthat isolates AA, BE and BK were strains of Pediococcus acidilactici (similarity 99%), while isolate AP and AG were strains of Lactobacillus casei (similarity 99-100%). Probiotic assays showed that more than 80% of cells of Pediococcus acidilactici isolates AA, BE and BK were viable after grown on pH 2.0 for 90 min, and around 80% of cells from the same isolates were survived on media supplemented with bile salt 1.5% for 2 h. All of isolates had high adhesion capacity as seen by more than 75% of cells attached on pig gastric mucin. Investigationof isolates to grow on inulin showed Pediococcus acidilactici isolate BE was able to consume inulin as the only carbon source. It is concluded that Pediococcus acidilactici isolate BE was a candidate probiotics and subject to further in vivo evaluation using animal models to examine their beneficial health effects.Key word : Pediococcus acidilactici, Lactobacillus casei, human origin and probiotics.

Abstract

Molecular Studies on Probiotic of Human Breast Milk in the Synthesis of Exopolysaccharide (EPS)  The glucosyltransferase (gtf) gene has an important role in exopolysaccharide (EPS) synthesis in probiotic bacteria. The EPS produced is associated with the adhesion ability of bacteria to the intestinal mucosa. Therefore, the gtf gene can be used as a parameter in the selection of potential probiotic through a molecular approach. This study was conducted to determine the presence of the gtf gene in probiotic from human breast milk using PCR technique. The methods in this study include the following: reculture of probiotic isolates, DNA isolation, amplification of the 16S rRNA gene using universal primers (pA and pB), amplification of specific LAB primers (LABfw and LABrv), specific primary design for the gtf gene, and the amplification of the gtf gene. The results of 16S rRNA gene amplification using universal primers obtained the amplicons of 500-1,000 bp in size. The results of amplification using specific LAB primers obtained an amplicon of about 700 bp in all isolates. The results of amplification of the gtf gene using a specific primer produced an amplicon of 325 bp in all isolates. Based on this study, it was concluded that 16 probiotic isolates from human breast milk were proven to have the gtf gene. Gen glukosiltransferase (gtf) memiliki peran penting dalam sintesis eksopolisakarida (EPS) pada bakteri probiotik. EPS yang diproduksi berhubungan dengan kemampuan adhesi bakteri pada mukosa usus. Oleh karena itu, gen gtf dapat dijadikan sebagai salah satu parameter dalam seleksi probiotik potensial melalui pendekatan molekuler. Penelitian ini dilakukan untuk mengetahui adanya gen gtf pada probiotik asal air susu ibu (ASI) menggunakan teknik PCR. Metode pada penelitian ini meliputi: reculture isolat probiotik, isolasi DNA, amplifikasi gen 16S rRNA menggunakan primer universal (pA dan pB), amplifikasi primer spesifik BAL (LABfw dan LABrv), desain primer spesifik untuk gen gtf dan amplifikasi gen gtf. Hasil amplifikasi gen 16S rRNA menggunakan primer universal diperoleh amplikon berukuran antara 500-1.000 bp. Adapun hasil amplifikasi menggunakan primer spesifik BAL diperoleh amplikon berukuran sekitar 700 bp pada seluruh isolat. Hasil amplifikasi gen gtf menggunakan primer spesifik menghasilkan amplikon berukuran sekitar 325 bp pada seluruh isolat. Berdasarkan penelitian ini dapat disimpulkan bahwa 16 isolat probiotik asal ASI terbukti memiliki gen gtf.

Abstract

Pengembangan produk olahan susu kambing terfermentasi dan diperkaya dengan probiotik Bifidobacterium bifidum merupakan salah satu produk pangan fungsional (Functional Food) yang selanjutnya disebut sebagai Susu Bifidus. Susu bifidus sebagai salah satu produk fermentasi susu dapat dikonsumsi oleh masyarakat yang mengalami kesulitan mencerna laktosa (lactose intolerance). Daya terima konsumen terhadap susu kambing masih tergolong rendah dibandingkan dengan susu sapi, sehingga hal tersebut juga perlu diantisipasi. Penambahan ekstrak cengkeh (Syzygium aromaticum) pada susu Bifidus dapat digunakan sebagai alternatif senyawa aromatik alami, untuk menghilangkan aroma goaty pada susu kambing yang kurang begitu disukai oleh konsumen. Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi ekstrak cengkeh terhadap viabilitas (daya hidup) dan aktivitas antibakteri Bifidobacterium bifidum serta kualitas kimia susu Bifidus. Parameter yang diamati pada penelitian adalah total Bifidobacterium bifidum, total bakteri dan luas zona bening susu Bifidus. Suplementasi ekstrak cengkeh sebesar 2% sebagai bahan suplementasi pada Bifidus milk dapat meningkatkan viabilitas probiotik Bifidobacterium bifidum. Ekstrak cengkeh dalam produk Bifidus milk berperan sebagai agen preservatif, didukung dengan adanya aktivitas antibakteri terhadap Staphylococcus aureus dan Salmonella typhimurium dan penurunan total bakteri pada Bifidus milk.

Abstract

Currently the use of probiotic food is growing rapidly, especially in Indonesia along with the development of fermentation technology. Most of the probiotic isolates come from abroad which has an impact on the high price of probiotic food products. Mother's milk is one source of lactic acid bacteria (LAB), which serves to maintain the balance of the digestive tract microflora and enhance the immune system. Lactic acid bacteria as probiotics have the chance to live in the digestive tract if they come from the human body. Based on this matter, it is necessary to conduct research as an effort to obtain indigenous BAL isolates from ASI. This study aims to obtain local BAL isolates from ASI through phenotypic identification. Phenotypic identification includes the morphology of colonies and cells, Gram, catalase test, motility and spore formation and biochemical identification including test of the ability to grow at various growth temperatures, low pH, salt content and formation of CO2 from glucose. Based on biochemical identification results, out of 38 BAL isolates that were successfully identified biochemically consisted of several genera of BAL namely Lactobacillus (9 isolates), Pediococcus (3 isolates) and Weisella (20 isolates).

Abstract

Bacteria is one of the microorganisms that we can easily find in nature. Bacteria can be classified into benefical bacteria and harmful bacteria. One of the bacteria classified as benefical bacteria is lactic acid bacteria (LAB). One of the bacteria included in LAB is probiotic bacteria.  Probiotic bacteria can be isolated from several sources, one of which is breast milk. The functionality of probiotics is seen by the production of exopolysaccharides (EPS). EPS is produced through the expression of the fructosyltransferase (ftf) gene. The samples used in this study were 16 isolates of candidate probiotic bacteria from breast milk. The stages of this research included reculture of probiotic isolates, isolation of bacterial genomic DNA, amplification of isolates with 16s rRNA primers, amplification of isolates with primary lactic acid bacteria (LAB) and amplification of isolates with specific primers of ftf gene. The results showed that 10 of 16 probiotic bacterial isolates had the ftf gene indicated by the presence of DNA bands on the electrophoregram with a size 58 bp.
