Jambal roti is a fermented fish product, commonly found in some regions in Java Island, Indonesia, such as Pekalongan, Cilacap, Pangandaran, Rembang, and along the northern coast. The raw sea catfish (Arius thalassinus) were traditionally processed by salting (salt amounting to 30% of the fish weight) then sun-drying. This study examined the microbiological and chemical characteristics of jambal roti produced in the Rembang Regency. Samples were taken from artisanal jambal roti producers during the making process. The proximate and chemical (final product of jambal roti) test results showed that the aw (0.723) and salt contents (18.166%) of the samples met the SNI 2721:2009, but the water (48.534%), ash (18.022%), and dissolved protein contents (5.494%) were above their allowable levels. The microbial analysis revealed that despite the absence of Escherichia coli and Salmonella spp. in the product, the total aerobic bacteria (APC) (6.6×102 CFU/g) and yeast and mold contamination (1.4×103 CFU/g) found in the samples were above the standards.

ABSTRACT Weissella cibaria 110, isolated from the Thai fermented fish product plaa-som, was found to produce a bacteriocin active against some gram-positive bacteria. Bacteriocin activity was not eliminated by exposure to high temperatures or catalase but was destroyed by exposure to the proteolytic enzymes proteinase K and trypsin. The bacteriocin from W. cibaria 110 was purified, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the purified bacteriocin contained one protein band that was approximately 2.5 kDa in size. Mass spectrometry analysis showed the mass of the peptide to be approximately 3,487.8 Da. N-terminal amino acid sequence analysis was performed, and 27 amino acids were identified. Because it has no similarity to other known bacteriocins, this bacteriocin was defined as a new bacteriocin and termed weissellicin 110.

Anchovies are traditional fish preserves, prepared from fermented fish of the engraulidae family, mainly in European countries. In Brazil, sardines (Sardinella brasiliensis) are an alternative fish for preparing these types of preserves, provided that the preservation process results in a high quality product. In this research, sardines were prepared for preservation and physicochemical, microbiological and sensory analyses were carried out during the preservation process. Whole or eviscerated sardines, with or without condiments/preservatives and with 20% of salt (w/w) were used. Sardines were analyzed fresh, and at 1, 15, 30, 45 and 60 days along the preservation process. The use of whole sardines, with or without condiments/preservatives, presented best results, with increased non-proteic nitrogen in the dry matter, higher levels of total volatile bases and higher contents of lactic acid and sodium chloride. The higher acidity observed in the whole sardine treatments resulted in better control of halophylic mesophilic microorganisms, which were kept under 1.4 x 10³ CFU g-1 in both treatments. Total coliforms and Staphylococcus aureus reached 21 and 3.0 x 10² CFU g-1, respectively. Escherichia coli and Salmonella spp were not present in the fresh sardines or in any of the four treatments, indicating that the concentration of salt used was appropriate to maintain the product under adequate microbiological control. Both whole or eviscerated sardines under the conditions of this experiment were appropriate in terms of the microbiological safety of the preserves. Treatments using whole fish, either with or without condiments/preservatives, also presented better sensorial properties such as color, flavor, taste and texture, as compared to the eviscerated fish treatments. Whole sardines produced good quality, anchovy-type preserves, which can be used for consumption and marketing purposes.

A study was conducted to identify the composition of volatile compounds from traditional fermented shrimp called ‘terasi’. Terasi samples were collected from six regions of northern coast of Central Java, Indonesia namely Pekalongan, Batang, Kendal, Demak, Jepara, and Pati. Mass spectral interpretation showed that terasi from these regions could be identified to contain a total of 102 volatile compounds. Terasi from Pekalongan, Batang, Kendal, Demak, Jepara, and Pati, each contained nine, 21, 10, 29, 12, and 21 volatile compounds respectively. There were four similar volatile compounds from Demak, Jepara, and Pati samples, and two distinctive off odor in all six regions.

In this study, the microbiological quality of traditionally produced Bez Sucuk in Tokat and its vicinity was investigated. For this purpose, 30 Bez Sucuk samples obtained from butchers, producers of Bez Sucuk, were analyzed for total count of mesophilic aerobic bacteria, lactic acid bacteria, yeasts-moulds, total coliform, fecal coliform, Staphylococcus aureus, Bacillus cereus, and Cl. perfringens. Also, the presence of Escherichia coli O157:H7, Listeria monocytogenes and Salmonella spp. were investigated in all samples. pH and water activity of the samples were determined. As the result of the analysis, the counts of the microbiological parameters investigated were found as follows: total mesophilic aerobic bacteria 3.5×106-4.23×109 CFU/g, lactic acid bacteria 5.55×105-2.45×109 CFU/g, yeasts and moulds 2.50×103-6.90×109 CFU/g, total coliform

Chao is a typical Indonesian dish from Pangkep Regency that is relatively unknown to the general public. Chao is made from fermented fish, which is subsequently fermented with rice. Chao has the properties of pasta-like, light-brown color, unique flavor, slightly acidic and salty taste. Pangkep communities typically use chao as a seasoning, condiment ingredient, or as a side dish. Due to the product's attractive features, which resemble stale food, make it less appealing to consumers. It necessitates innovation and processing technologies in order to improve the quality of Chao products. This research this study aimed to find out the effect of rice variations including white rice, red rice and black rice on the characteristics of Shrimp Chao during fermentation. The testing parameters in this study were total Lactic Acid Bacteria (LAB), total lactic acid, pH, and organoleptic. The highest LAB growth was found in the red rice that is 7.67 log cfu/g with the lowest pH value of 6.02 and the highest lactic acid content (1.8%). The best organoleptic test results own by white rice-based shrimp chao with preference average score of 3.85 and red rice 3.78 which imply “like” in organoleptic scale scoring.

Abstract. Wadi is a sort of fermented fish product from Dayak tribe in Central Kalimantan. Wadi is made with the addition of lumu, sugar, and salt, and fermented for 7-10 x 24 hours. During the fermentation process, there are microflora from fish, and microflora from lumu that play a role in fermentation process. Some species of bacteria that play a role in the wadi fermentation process are lipolytic bacteria and Lactic Acid Bacteria (LAB). This research aims to: (1) identify the species of lipolytic bacteria and LAB that present in the wadi, (2) determine the lipid hydrolysis index and lactic acid clearance zone index of lipolytic bacteria and LAB that present in the wadi, and (3) determine the species of lipolytic bacteria and LAB which have highest ability to hydrolyze lipid and have the highest ability to produce lactic acid based on lipid hydrolysis index and lactic acid clearance zone index. The results showed that, (1) there are four species of lipolytic bacteria and LAB present in wadi: Lactobacillus coryniformis, Lactobacillus casei, Nitrococcus mobilis and Streptococcus lactis; (2) the four species of bacteria have  different lipid hydrolysis index and lactic acid clearance zone index which are Lactobacillus coryniformis has a lipid hydrolysis index of 1.63 and lactic acid clearance zone index of 3.31; Lactobacillus casei has index of 1.94 and 3.96; Streptococcus lactis has index of 1.51 and 1.54 and Nitrococcus mobilis has index of 0.98 and 1.52; (3) Lactobacillus casei is a species of lipolytic bacteria and LAB which has the highest ability to hydrolyze lipid and to produce the highest lactic acid based on the lipid hydrolysis index and lactic acid clearance zone index, which are 1.94 and 3.96. Keywords: lipolitic bacteria, LAB, lipid hydrolysis index, lactic acid clearance zone, wadi.
