However, high salt content is known as a key factor to hinder its sales in current health-conscious society. Based on the guideline of Korean Standards, the fermented or seasoned fish products including salted-seasoned squids should contain fish as a raw material more than 75% in the products. An immunostimulatory LAB strain, which was characterized by this research group, was deliberately added into both the squid and the oyster samples for examining quality change during storage. 300 g of each sample was divided into two storage conditions: 5 ˚ C and room temperature, 20 ˚ C. As a result, all the samples with LAB tend to increase in viable cell counts under room temperature preservation, especially in the fermented oyster samples with LAB increase 100 times after 2 weeks storage. On the other hand, it was noted that general bacterial counts maintain almost constant in all the samples irrespective to addition of LAB. Judging from the bacterial examination, the addition of LAB in the squid and the fermented oyster samples neither affects the changes of LAB and general bacterial counts nor inhibits the bacterial growth in this experimental settings. It is not expected the increase in LAB added during the usual shelf life of the commercial products. Compared to non-LAB samples, overall acceptance was significantly better for the samples added LAB. In conclusion, this experiment suggests that addition of LAB is strongly recommended to develop low-salt fermented fish and shellfish products of higher sensory qualities.","PeriodicalId":10892,"journal":{"name":"Current Topic in Lactic Acid Bacteria and Probiotics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88755176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are commonly incorporated into a variety of functional foods or drug formulations. However, technical limitations such as viability controls have hindered their full potential applications for functional foods. Therefore, non-viable bacteria and/or derived biomolecules, namely postbiotics can be used for overcoming this limitation. The postbiotics are the inanimate microbial cells of probiotics or cell components such as peptidoglycans, teichoic acids, and exopolysaccharides. The various beneficial properties of postbiotics include anti-inflammatory, gut barrier property, antimicrobial, immunomodulatory, antihypertensive, hypocholesterolemia and antioxidant. These benefits suggest the potentiality of postbiotics to enhance the host health by ameliorating or preventing the disease conditions. However, there is still a high need for human/clinical trials focusing on the validation of health claims of these bioactive molecules or cells. Here, the concepts and various applications of postbiotics for the development of functional foods or drugs with their potential health benefits are summarized and discussed.","PeriodicalId":10892,"journal":{"name":"Current Topic in Lactic Acid Bacteria and Probiotics","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79553015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumers are becoming increasingly interested in healthy and functional foods. The lactic acid bacteria (LAB) and probiotics have health-promoting functions and can facilitate the growth of useful bacteria, inhibit harmful bacteria, and promote smooth bowel movements. This study compared the contents of LAB in various foods, including biscuit, sand, and chocolate, according to the storage period of LABcontaining products and analyzed the predominant LAB at the end of storage. Upon examining the changes in the viability of lactic acid bacteria over a storage period of 7 months, we found that cell viability was maintained at 5.20—9.04 Log CFU/g on MRS agar and 5.60—9.18 Log CFU/g on BCP agar. The results of cross-testing by a certified food safety agency by the MFDS, demonstrated that cell viability was maintained at 5.65—8.34 Log CFU/g; additionally, cross-validation comparison results showed a similarity of 76.0%—100%. This indicated high accuracy of results and maintenance of the constant viability of lactic acid bacteria. The detected lactic acid bacteria in various foods were identified as Lactiplantibacillus (96—100%), Weissella confusa (99%), and Streptococcus thermophiles (99%).

The inhibitory activity by bacteriocins produced by lactic acid bacteria is diverse, comprising of strains capable of inhibiting different types of Gram-positive microorganisms to those that affect only organism of close general. With the growing concern over the spread of antibiotic-resistant microorganisms and the possibility of current therapies becoming inefficient, it is imperative to find antibiotics alternatives. In food preservation, naturally occurring peptides with antimicrobial activity are favoured over chemical preservatives a more reason why there should be a holistic approach to taking advantage of bacteriocinogenic bacteria in medicine and food industry.

The improved syrup was prepared by adding monosodium glutamate (MSG) to saccharified rice and using a complex of three types of lactic acid bacteria (Lactobacillus brevis, Lactobacillus plantarum, Leuconostoc mesenteroides) with excellent GABA production ability. The physicochemical changes of the fermented rice syrup were measured, and the final pH of the product was 4.7 with a total water-soluble solid content of 22.1 °Brix. Of the dissolved solids, glucose (39.6 mg/mL) and maltose (12.7 mg/mL) were the main components, and it was confirmed that all MSG was converted to GABA. From the experiment, it was established that the rice syrup obtained from secondary fermentation of saccharified rice is suitable as a beverage base. The fermented saccharified rice syrup was differentiated from conventional rice fermented products which typically use yeast and acetic acid bacteria in the production process. The enhanced fermented rice syrup produced in this study was made using lactic acid bacteria in the fermentation and saccharified rice.","PeriodicalId":10892,"journal":{"name":"Current Topic in Lactic Acid Bacteria and Probiotics","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82478377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of probiotics in the swine industry aims to improve animal health and productivity by forming a healthy gut microbiota. Intensive pig breeding, a common breeding method in modern society, causes physiological stress in pigs, resulting in imbalance of the intestinal microbiota and dysfunction of the intestinal barrier. We conducted a scientific research on the properties of probiotics for multi-strain probiotics (MSP) and observed the economic benefits and efficiency of culturing MSP through a self-cultivation system in livestock. Initially, we observed alteration occurred by MSP application in the gut microbiota of pig. MSP were characterized to have resistance to digestive juices such as gastric acid and bile, followed by colonization in the target organ, the gastro-intestinal tract (GIT). In addition, MSP was also confirmed to have antibacterial ability against pathogenicity that most frequently infected in the swine industry and showed low resistance to antibiotics which means guaranteed stability when added to feed. The growth rate of probiotics in the optimized medium used in the self-cultivation system was suitable for efficiently and economically culturing and feeding pigs with high concentrations of probiotics, considering the ingredient price and the growth efficiency. We observed the significant alteration of gut microbiota of pig by application of MSP. Importantly, the MSP supplementation significantly increased the beneficial bacteria genus of Bifidobacterium that confer a health benefit to the host in pig GIT, whereas decreased the number of harmful bacteria including coliforms. In addition, MSP influenced on the uniformity of gut microbiota at both of sow and weaning pigs. Taken together, the application of MSP with high concentration of probiotics using self-cultivation system may critically improve the pig health by regulation intestinal microbiota.","PeriodicalId":10892,"journal":{"name":"Current Topic in Lactic Acid Bacteria and Probiotics","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73896095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
