Tempe bungkus daun jati merupakan produk pangan fermentasi tradisional Indonesia yang kaya protein, serat, dan vitamin yang sangat popular di Kabupaten Blora, Jawa Tengah. Penelitian ini bertujuan mengetahui pengaruh penambahan daun kelor pada tahapan perendaman dan peragian dalam proses produksi tempe terhadap profil bakteri asam laktat (BAL) dan tingkat kesukaan. Daun kelor segar dan serbuk disuplementasikan dengan variasi konsentrasi pada proses produksi tempe kacang kedelai. Hasil penelitian menunjukkan bahwa daun kelor tidak menghambat aktivitas pertumbuhan dari kapang Rhizopus. Penambahan serbuk daun kelor sebanyak 1x dan 2x (b/b) dari total jumlah ragi pada proses peragian menghasilkan tekstur tempe yang kompak. Semakin tinggi konsentrasi air perasan daun kelor dalam proses perendaman, jumlah total bakteri asam laktat menurun hingga 103 CFU/g. Profil BAL dari tempe bungkus daun jati dengan ataupun tanpa suplementasi daun jati mengandung BAL dari genus Weissella. Tempe bungkus daun jati dengan suplementasi 1x (b/b) serbuk daun kelor sangat berpotensi untuk disosialisasikan sebagai pangan fungsional kepada masyarakat.Lactic Acid Bacteria Profile and Sensory Evaluation of Teak Leaf-Wrapped Tempeh Supplemented with Moringa LeavesAbstractTempeh wrapped in teak leaves is a traditional Indonesian fermented food product that is rich in protein, fiber, and vitamins which is very popular in Kabupaten Blora, Central Java. This study aimed to investigate the effect of Moringa leaves addition in the soaking and fermentation stages of tempeh production towards the profile of lactic acid bacteria (LAB) and the level of respondent acceptance. Fresh and powdered leaf was supplemented in various doses to soybean tempeh production. As results, Moringa leaves did not inhibit the growth of Rhizopus. The addition of Moringa leaf powder as much as 1x and 2x (w/w) of the total amount of yeast in the fermentation process produced a compact tempeh texture. The higher the concentration of Moringa leaf juice in the soaking process reduced total number of lactic acid bacteria to 103 CFU/g. LAB profile of teak leaf-wrapped tempeh with or without teak leaf powder supplementation contained LAB that belongs to the genus Weissella. Teak leaf-wrapped tempeh supplemented by 1x (w/w) Moringa leaf powder has a potential value to be socialized as functional food to the community.

Introduction: Fermentation is a biotechnological process of preserving the biological potential of raw materials and transforming them in order to impart new organoleptic properties and to increase nutritional value of the product allowing diversification of daily meals; thus, in some countries fermented products make up a significant part of the human diet. Despite the fact that fermented products are very useful for humans, the fermentation process itself remained rather complicated for reproduction during a long time. Currently, starter cultures are used in industrial production of fermented food products enabling the production of foodstuffs with a guaranteed range of consumer properties. Such species of lactic acid bacteria as Carnobacterium, Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Oenococcus, Pediococcus, Streptococcus, Tetragenococcus, Vagococcus, and Weissella play the main role in production of fermented food and drinks while L. mesenteroides plays the primary role in starting fermentation of many types of plant materials including cabbage, beet, turnip, cauliflower, green beans, chopped green tomatoes, cucumbers, olives, etc. Objective: To control and manage the industrial fermentation process, it is important to determine the main processes occurring at different stages and the types of lactic acid microorganisms responsible for initiation, continuation and completion of the process. Results: This review shows that, despite the variety of fermentable vegetables, L. mesenteroides species of lactic acid bacteria are of particular importance at the primary heteroenzymatic stage since during this very period the processed raw materials form conditions for inhibiting pathogenic and facultative pathogenic microflora and create optimal environment for subsequent development of targeted microorganisms determining the quality of finished products. Conclusions: When developing food technology, L. mesenteroides species of lactic acid bacteria must be an indispensable component of industrial starter cultures for obtaining final products of consistently high quality.6

Pekasam is one of Malaysia s famous fermented product. Pekasam fish is usually made from freshwater fish with ground roasted fragrant rice as the main ingredient as the fermentation substrate. Fermented food, especially from fish or seafood requires lactic acid bacteria such as Lactobacillus spp. to aid the fermentation process. Samples were fermented for 30 days based on natural fermentation of pekasam. Protein has a significant effect on the taste, flavor, color and shelf life of the pekasam fish. The objective of this study is to evaluate the effect of protein content on selected fish in relation to the production of lactic acid bacteria. It showed that the increment of Lactobacillus spp. associated with the higher amount of protein in the fish during the fermentation process. Patin fish showed the highest protein content (27.5%) with the highest increment in Lactobacillus spp. This suggests possible use of Patin fish as a potential source to improve the overall quality of fermented fish product.

Food fermentation is one of various food processing techniques that has sufficient benefits of nutrition values, and also contains lactic acid bacteria which potentially inhibit pathogenic bacteria, thus prolong shelf life of  products. Bakasang is a traditional fermented food from North Sulawesi since many years ago. Reported research of bakasang previously had described that lactic acid bacteria was the dominant isolates and therefore current research  aimed to isolate and identify the lactic acid bacteria which associated during fermentation day 1 and day 15, respectively. Raw materials used were 5 kg intestine and liver of skipjack brought from local market Bersehati Manado. The intestine and liver of skipjack were washed and smashed and mixed with 10% salt  and 5% rice  from weight of the samples and then filled into bottle to be fermented for 15 days. Every 3 days (1,3,6,9,12,15), the samples were collected and analyzed for total lactic acid bacteria by using Total Plate Count Method on de Mann Rogosa Sharpe Agar after incubation at 37°C for 24 h. The colonies  grown were transferred to Tryptic Soy Broth and followed by streaking them on Tryptic Soy Agar and the free growing colony on agar medium were isolated into slant agar which were used for biochemical test such as Gram’s staining, motility test, catalase test, oksidase test, H2S test, IMVIC test (Indole, Methyl Red, Voges Proskauer, Citrate) and carbohydrate fermentation. The results showed that Lactobacillus sp., Bacillus sp., Eubacterium sp., and Bifidobacterium sp. All these four bacteria were distributed from day 1 to day 15 of the fermentation process© Fermentasi bahan pangan merupakan salah satu dari sekian banyak teknik pengolahan makanan yang mempunyai banyak manfaat dari kualitas gizi, mengandung bakteri asam laktat sehingga menghambat bakteri patogen sehingga daya simpan lebih panjang. Bakasang merupakan makanan fermentasi tradisional masyarakat Sulawesi Utara yang sudah ada sejak lama. Penelitian yang telah dilakukan terhadap bakasang menghasilkan informasi bahwa terdapat bakteri asam laktat pada bakasang sehingga menjadi tujuan untuk mengisolasi dan identifikasi bakteri asam laktat selama proses fermentasi 1-15 hari. Bahan baku bakasang ialah jeroan (usus dan hati) ikan cakalang Katsuwonis pelamis sebanyak 5 kg yang diambil dari pasar Bersehati Manado. Sampel jeroan dibersihkan kemudian dihancurkan, ditambahkan garam 10% dan nasi 5% kemudian difermentasi selama 15 hari dengan mengambil tiap-tiap sampel setiap 1, 3, 6, 9, 12, dan 15 untuk dihitung jumlah bakteri asam laktat dengan menggunakkan metode Total Plate Count pada media de Mann Rogosa Sharpe Agar dan koloni yang tumbuh di tumbuhkan  kembali pada media Tryptic Soy Broth  dan digores kembali pada media Tryptic Soy Agar, koloni yang tumbuh digores pada media slant agar yang selanjutnya diidentifikasi bakteri asam laktat berdasarkan uji biokimia yaitu uji pewarnaan Gram, uji motility, uji katalase, uji oksidase, uji H2S dan uji IMVIC (Indole, MethylRed, Voges Proskauer, Citrate). Hasil menunjukkan bahwa selama proses fermentasi berlangsung terdapat 4 genera bakteri asam laktat sesuai yaitu Lactobacillus sp., Bacillus sp., Eubacterium sp., dan Bifidobacterium sp., ke 4 genera ini tersebar pada fermentasi hari 1 sampai hari ke 15©

Tabah bamboo shoot pickle is one of the fermented food which is the source of lactic acid bacteria.  Lactic acid bacteria (LAB) is beneficial to health because it has the ability as a probiotic. Lactic acid bacteria that have probiotic criteria should have resistance to low pH and bile salts. This study aims to determine isolates of lactic acid bacteria isolated from tabah bamboo shoot pickle resistant to low pH and bile salts (NaDC). Lactic acid bacteria were tested to low pH by using MRS broth that have different pH (pH 2, pH 3, pH 4 and pH 6.2 as a control) incubated at 37ºC for 3 hours. isolates were survive in low pH then continued in bile salt resistance test with 0.3% bile salt concentration for 15 minutes, 30 minutes, 45 minutes, 60 minutes and 24 hours. The results showed that three isolates out of 88 isolates had ability to grow in low pH and in medium supplemented by NaDC 0,3%. The isolates are AR 3057, AR 3101 and AR 6152 which can be used as candidat of  probiotic. Keywords : Tabah bamboo shoot pickle, lactic acid bacteria, probiotic, low pH, bile salt

Gram Positive Bacteria

In the present study, the antibacterial effect of 20 lactic acid bacteria isolates from a traditional cheese was investigated. 6 isolates showed antibacterial effect against Gram positive bacteria.Streptococcus thermophilusT2 strain showed the wide inhibitory spectrum against the Gram positive bacteria. Growth and bacteriocin production profiles showed that the maximal bacteriocin production, byS. thermophilusT2 cells, was measured by the end of the late-log phase (90 AUml−1) with a bacteriocine production rate of 9.3 (AUml−1)h−1. In addition, our findings showed that the bacteriocin, produced byS. thermophilusT2, was stable over a wide pH range (4–8); this indicates that such bacteriocin may be useful in acidic as well as nonacidic food. This preliminarily work shows the potential application of autochthonous lactic acid bacteria to improve safety of traditional fermented food.
