Based on previous research it was found that lemea (traditional food rejang) was proven to contain 2 types of lactic acid bacteria (BAL) namely L.aplantarum C410L1 and L. crossiae LS6 which could be probiotic and beneficial for health. The development of lemea as a potential probiotic must be proven its resistance to bile acids and salts as an indication of being able to survive in the gastrointestinal tract. This study aims to determine the resistance of BAL isolated from lemea against low pH, bile acids, and temperature. This research is an experimental study with all research units controlled. Analysis of BAL resistance to high temperatures, low pH, and bile salts was carried out in the Bengkulu Polytechnic Health Polytechnic laboratory. The total BAL colonies increased at 49 ° C and decreased at 64 ° C. The increase in the total number of BAL colonies within 0-30 hours occurred at pH 5 and pH 6. There was no increase or decrease in the total number of BAL colonies in salts 0.30%, 0.60%, and 0.90%. The diisolate lactic acid (BAL) bacteria from lemea have a temperature resistance of 42 ° C to 64 ° C, pH 2 to pH 7, have a salt resistance concentration of 0.30% to 0.90%. Lactic acid bacteria (BAL) which are diisolate from lemea have the potential as probiotics.

Microorganisms inhabiting fermented foods represent the main link between the consumption of this food and human health. Although some fermented food is a reservoir of potentially probiotic microorganisms, several foods are still unexplored. This study aimed at characterizing the probiotic potential of lactic acid bacteria isolated from zgougou, a fermented matrix consisting of a watery mixture of Aleppo pine′s seeds. In vitro methods were used to characterize the safety, survival ability in typical conditions of the gastrointestinal tract, and adherence capacity to surfaces, antimicrobial, and antioxidant activities. Strains belonged to the Lactobacillus plantarum group and Enterococcus faecalis showed no DNase, hemolytic, and gelatinase activities. In addition, their susceptibility to most of the tested antibiotics, satisfied some of the safety prerequisites for their potential use as probiotics. All the strains tolerated low pH, gastrointestinal enzymes, and bile salts. They displayed a good antibacterial activity and antibiofilm formation against 10 reference bacterial pathogens, especially when used as a cell-free supernatant. Furthermore, the lactic acid bacteria (LAB) strains inhibited the growth of Aspergillus flavus and Aspergillus carbonarius. Finally, they had good antioxidant activity, although depending on the strain. Overall, the results of this work highlight that zgougou represents an important reservoir of potentially probiotic LAB. Obviously, future studies should be addressed to confirm the health benefits of the LAB strains.

Abstract The aim of this work was to evaluate presence and properties of lactic acid bacteria in the faeces of 240 volunteers with various nutrition habits (vegetarians versus meat-eaters). Lactic acid bacteria counts in all age groups were nearly 5 or 6 logarithmic orders. Significantly higher amounts were found in women. Subsequently, based on the age and dietary pattern of probands, four samples were selected for isolation of lactic acid bacteria and identification of isolates in order to assign them to bacterial species. About 80 lactic acid bacteria were isolated from the faeces of young (21-30 years) and older (51-60 years) vegetarians and meateaters. The identification of the isolates was based on their morphological and biochemical characteristics. Isolates belong to lactobacilli, bifidobacteria, enterococci and propionibacteria. Surprisingly, bifidobacteria were predominated in older age group. The following probiotic properties were determined: survival at low pH value, and bile salt hydrolase activity. All strains were negative in bile salt hydrolase activity, but their growth was not inhibited in the presence of bile. The results from the study of survival at low pH value showed considerable variability in both dietary groups regardless the age of probands. However, it can be concluded, that bacteria isolated from the samples of older probands were more sensitive to acid pH.

The suitable properties of potential probiotic lactic acid bacteria (LAB) strains (preselected among 153 strains on the basis of their potential technological properties) isolated from traditional Çubuk pickles were examinedin vitro. For this purpose, these strains (21Lactobacillus plantarum, 11Pediococcus ethanolidurans,and 7Lactobacillus brevis) were tested for the ability to survive at pH 2.5, resistance to bile salts, viability in the presence of pepsin-pancreatin, ability to deconjugate bile salts, cholesterol assimilation, and surface hydrophobicity properties. Most of the properties tested could be assumed to be strain-dependent. However,L. plantarumandL. brevisspecies were found to possess desirable probiotic properties to a greater extent compared toP. ethanolidurans. In contrast toP. ethanoliduransstrains, the testedL. plantarumandL. brevisstrains exhibited bile salt tolerance, albeit to different extent. All tested strains showed less resistance to intestinal conditions than gastric juice environment. Based on the survival under gastrointestinal conditions, 22 of the 39 strains were selected for further characterization. The eight strains having the highest cholesterol assimilation and surface hydrophobicity ratios could be taken as promising probiotic candidates for furtherin vivostudies, because of the strongest variations found among the tested strains with regard to these properties.

Probiotic Lactic Acid Bacteria

Research on lactic acid bacteria has confirmed how specific strains possess probiotic properties and impart unique sensory characteristics to food products. The use of probiotic lactic acid bacteria (LAB) in many food products, thus confers various health benefits to humans when they are frequently consumed in adequate amounts. The advent of functional food or the concept of nutraceuticals objectively places more emphasis on seeking alternatives to limit the use of medications thus promoting the regular consumption of fermented foods. Probiotic use has thus been recommended to fulfill the role of nutraceuticals, as no side effects on human health have been reported. Probiotics and lactic acid bacteria can boost and strengthen the human immune system, thereby increasing its resistance against numerous disease conditions. Consumer safety and confidence in dairy and fermented food products and the desire of the food industry to meet the sensory and health needs of consumers, has thus increased the demand for probiotic starter cultures with exceptional performance coupled with health benefiting properties. The potential of probiotic cultures and lactic acid bacteria in many industrial applications including fermented food products generally affects product characteristics and also serves as health-promoting foods for humans. The alleviation of lactose intolerance in many populations globally has been one of the widely accepted health claims attributed to probiotics and lactic acid bacteria, although many diseases have been treated with probiotic lactic acid bacteria and have been proven with scientific and clinical studies. The aim of our review was to present information related to lactic acid bacteria, the new classification and perspectives on industrial applications with a special emphasis on food safety and human health.

Background and Aim: Probiotics play an important role in maintaining a healthy gut and consequently promote good health. This study aimed to find novel probiotic lactic acid bacteria (LAB) from indigenous fermented foods of West Sumatera, Indonesia. Materials and Methods: This study utilized 10 LAB previously isolated from fermented buffalo milk (dadih), fermented fish (budu), and fermented cassava (tape) which have the ability to produce gamma-aminobutyric acid. The study commenced with the screening of LAB for certain properties, such as resistance to acid and bile salts, adhesion to mucosal surface, and antagonism against enteric pathogens (Escherichia coli, Salmonella Enteritidis, and Staphylococcus aureus). The promising isolates were identified through biochemical and gram staining methods. Results: All isolates in this study were potential novel probiotics. They survived at a pH level of 2.5 for 3 h (55.27-98.18%) and 6 h (50.98-84.91%). Survival in bile at a concentration of 0.3% was 39.90-58.61% and the survival rate was 28.38- 52.11% at a concentration of 0.5%. The inhibitory diameter ranged from 8.75 to 11.54 mm for E. coli, 7.02 to 13.42 mm for S. aureus, and 12.49 to 19.00 mm for S. Enteritidis. All the isolates (84.5-92%) exhibited the ability to adhere to mucosal surfaces. This study revealed that all the isolates were potential probiotics but N16 proved to be superior because it was viable at a pH level of 2 (84.91%) and it had a good survival rate in bile salts assay (55.07%). This isolate was identified as Lactobacillus spp., Gram-positive bacilli bacteria, and tested negative in both the catalase and oxidase tests. Conclusion: All the isolates in this study may be used as probiotics, with isolate N16 (Lactobacillus spp.) as the most promising novel probiotic for poultry applications based on its ability to inhibit pathogenic bacteria.
