Tambelo (Bactronophorus sp.) is a wood borer grouped into mollusc and living in the mangrove logs that have died and suffered from decaying process. Regarding empirical experience of the coastal people of Southeast Sulawesi and some research, it indicates that tambelo has a high nutrition which is so beneficial for human’s health. Tambelo is highly perishable and the usage of it is hardly found so the consumption level is low, therefore fermenting the tambelo is the right way. The objectives of this research are to make fermentated tambelo by using bakasang as a starter and to determine the quality of final product.The value of pH, NaCl concentration, total bacteria, and total lactic acid bacteria (LAB) every week for 4 week were analyzed during fermentation, then the quality of final product were determined based on chemical composition and amino acids. During fermentation pH and NaCl concentration decreased however total bacteria and total lactic acid bacteria (LAB) increased in to two weeks then decreased until the fourth week. Tambelo fermentation has a total protein contents which is higher than the total protein of fresh tambelo and fermentation proses was run perfectly although the level are lower than the total amino acid compotition in fresh tambelo.<br />Keywords: fermentation, mangrove, tambelo

Manufacture of probiotic product that has been done a lot is manufacture of yoghurt. In the process, addition of red beans and prebiotic is done to add value to the product. Addition of Lactic Acid Bacteria and inulin in the form of banana flour with different amounts is done to find the right synbiotic yogurt formulation. This research was conducted to test the quality of product physically, chemically, microbiology and organoleptics. This research was conducted using a Completely Randomized Design with the first factor being the BAL levels added and the second factor being the levels of inulin added. Based on the tests, the results obtained that the formulation using L. plantarum as much as 1% and 2% commercial inulin is the right formulation with results that are in accordance with SNI 2891: 1992 standards. The total value of LAB resulting from the formulation is 3.24 x 106 cfu/ml with a total non-fat solid of 11.16%.

Based on the raw materials, inasua consists of two types namely inasua with sap and inasua without sap. Research of inasua with sap has never been done and considered as the novelty of this research. The sensory characteristics and shelf life of two types of inasua were different. The research aims to analyze the microbiological and physicochemical characteristics of two types of inasua during fermentation. The microbiological analyzes include the total number of bacteria and lactic acid bacteria, while physicochemical analyzes include temperature, pH, water activity, proximate analysis, salt, alcohol, histamine, amino acids and fatty acids contents. The total number of bacteria and lactic acid bacteria has decreased during fermentation. At the end of the fermentation the total number of bacteria and lactic acid bacteria inasua with sap were 3.2x107 CFU/g and 3.0x107 CFU/g, while inasua without sap were 5.4x105CFU/g and 3.5x105 CFU/g, respectively. The moisture, protein, alcohol contents and water activity decreased, otherwise the salt, fat, ash, amino acids, and fatty acids contents increased during fermentation. Generally, microbiological and physicochemical characteristics of inasua with sap was better than inasua without sap. The results of this research to improve the quality of this fermentation product in the future.

Hardening of cheese is one of major issues that degrade the quality of Home Meal Replacement (HMR) foods containing cheese such as Cheese-ddukbokki rice cake (CD, stir-fried rice cakes with shredded cheese). The quality of cheese, such as pH, proteolytic, and flavor properties, depends on various lactic acid bacteria (LAB) used in cheese fermentation. The hardening of cheese is also caused by LAB. In this study, various LAB strains were isolated from CD samples that showed rapid hardening. The correlation of LAB with the hardening of cheese was investigated. Seven of the CD samples with different manufacturing dates were collected and tested for hardening properties of cheese. Among them, strong-hardening of cheese was confirmed for two samples and weak-hardening was confirmed for one sample. All LAB in two strong-hardening samples and 40% of LAB in one weak-hardening sample were identified as Latilactobacillus curvatus. On the other hand, most LAB in normal cheese samples were identified as Leuconostoc mesenteroides and Lactobacillus casei. We prepared cheese samples in which L. curvatus (LC-CD) and L. mesenteroides (LM-CD) were most dominant, respectively. Each CD made of the prepared cheese was subjected to quality test for 50 days at 10 °C. Hardening of cheese with LC-CD dominant appeared at 30 days. However, hardening of cheese with LM-CD dominant did not appear until 50 days. The pH of the LC-CD was 5.18 ± 0.04 at 30 days, lower than that of LM-CD. The proteolytic activity of LC-CD sample was 2993.67 ± 246.17 units/g, higher than that of LM-CD sample (1421.67 ± 174.5 units/g). These results indicate that high acid production and high protease activity of L. curvatus might have caused hardening of cheese.

Lactic acid bacteria (LAB) are naturally associated with many foods or their raw ingredients and are popularly used in food fermentation to enhance the sensory, aromatic, and textural properties of food. These microorganisms are well recognized for their biopreservative properties, which are achieved through the production of antimicrobial compounds such as lactic acid, diacetyl, bacteriocins, and other metabolites. The antifungal activity of certain LAB is less well characterized, but organic acids, as yet uncharacterized proteinaceous compounds, and cyclic dipeptides can inhibit the growth of some fungi. A variety of microbes are carried on raw materials used in beer brewing, rendering the process susceptible to contamination and often resulting in spoilage or inferior quality of the finished product. The application of antimicrobial-producing LAB at various points in the malting and brewing process could help to negate this problem, providing an added hurdle for spoilage organisms to overcome and leading to the production of a higher quality beer. This review outlines the bioprotective potential of LAB and its application with specific reference to the brewing industry.

Bacteria Culture

Mixed lactic acid bacteria culture is commonly used in yogurt production. In the present study, two lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophillus) was used as starter culture. Calcium carbonate was added to the starter culture to increase the quality of mixed starter culture of L. bulgaricus and S. thermophillus with ratio of 4:1. The present study was directed to investigate the chemical composition of mixed starter culture with and without calcium carbonat addition. Furthermore, the effect of each starter culture on yogurt product chemical composition was also examined. The pH, lactose, soluble protein and acid content was determined as chemical composition parameters. For starter culture without calcium carbonate addition, the yogurt has pH, lactose, soluble protein and acid content of 4.18–4.39, 4.18–4.39% w/v, 2.88–4.36% w/v and 0.82–0.99% w/v, respectively. While for starter culture with calcium carbonate addition, the yogurt product has pH, lactose, soluble protein and acid content of 4.26–4.37, 1.47–1.75% b/v, 3.42–4.95% w/v and 0.86–1.11% w/v, respectively. Addition of 0.05% w/v calcium carbonate to mixed starter culture gave effect on lactose consumption, where it still can convert lactose to lactic acid up to 45 days of storage. Furthermore, the yogurt product made with starter culture with calcium carbonate addition has higher soluble protein content compared to yogurt made with starter culture without calcium carbonate addition
