Colmenares-Cuevas SI, Contreras-Oliva A, Salinas-Ruiz J, Hidalgo-Contreras JV, Flores-Andrade E, García-Ramírez EJ. Development and study of the functional properties of marshmallow enriched with bee ( Apis mellifera) honey and encapsulated probiotics ( Lactobacillus rhamnosus). Front Nutr 2024; 11:1353530. [PMID: 38699548 PMCID: PMC11063280 DOI: 10.3389/fnut.2024.1353530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 04/01/2024] [Indexed: 05/05/2024] Open
Abstract
Consumer demand for healthier confectionery products has prompted the confectionery industry to create products that are reduced in sugar content and supplemented with vitamins, antioxidants or biological elements beneficial to health. The aim of this study was to develop marshmallows enriched with Apis mellifera honey and Lactobacillus rhamnosus and to evaluate the effect of honey concentration and gelatin bloom degrees on marshmallow properties. A completely randomized design with a factorial structure was applied with different honey concentrations (0, 50 and 75%) and at different gelatin bloom degrees (265, 300 and 315 bloom degrees); moreover, the physicochemical properties, total phenol content and antioxidant activity of the marshmallow were studied, as well as the viability of the probiotic. The physicochemical properties of the marshmallows were found to be adequate and showed good stability over time. The concentration of honey and gelatin bloom degrees did not significantly affect probiotic viability. The density of the marshmallows decreased as the percentage of honey increased. Additionally, the pH was lower at higher honey concentrations. The marshmallow with 75% honey and 265 bloom degrees had a higher °Brix value. The honey treatments exhibited higher levels of total antioxidant activity and total phenolic compounds than the sugar-only marshmallows. However, the bloom degrees did not have a significant impact on the antioxidant activity and total phenolic compound content. Although the probiotics did not reach the minimum viability needed, their use as paraprobiotics can be considered.

Abstract
Inuit of Nunavik are coping with living conditions that can influence respiratory health. Our objective was to investigate associations between respiratory health in Inuit communities and their airway microbiome. Oropharyngeal samples were collected during the Qanuilirpitaa? 2017 Inuit Health Survey and subjected to metagenomic analyses. Participants were assigned to a bronchial obstruction group or a control group based on their clinical history and their pulmonary function, as monitored by spirometry. The Inuit microbiota composition was found to be distinct from other studied populations. Within the Inuit microbiota, differences in diversity measures tend to distinguish the two groups. Bacterial taxa found to be more abundant in the control group included candidate probiotic strains, while those enriched in the bronchial obstruction group included opportunistic pathogens. Crossing taxa affiliation method and machine learning consolidated our finding of distinct core microbiomes between the two groups. More microbial metabolic pathways were enriched in the control participants and these were often involved in vitamin and anti-inflammatory metabolism, while a link could be established between the enriched pathways in the disease group and inflammation. Overall, our results suggest a link between microbial abundance, interactions and metabolic activities and respiratory health in the Inuit population.

Abstract
Combatting the rapidly growing threat of antimicrobial resistance and reducing prevalence and transmission of ESKAPEE pathogens in healthcare settings requires innovative strategies, one of which is displacing these pathogens using beneficial microorganisms. Our review comprehensively examines the evidence of probiotic bacteria displacing ESKAPEE pathogens, with a focus on inanimate surfaces. A systematic search was conducted using the PubMed and Web of Science databases on 21 December 2021, and 143 studies were identified examining the effects of Lactobacillaceae and Bacillus spp. cells and products on the growth, colonization, and survival of ESKAPEE pathogens. While the diversity of study methods limits evidence analysis, results presented by narrative synthesis demonstrate that several species have the potential as cells or their products or supernatants to displace nosocomial infection-causing organisms in a variety of in vitro and in vivo settings. Our review aims to aid the development of new promising approaches to control pathogen biofilms in medical settings by informing researchers and policymakers about the potential of probiotics to combat nosocomial infections. More targeted studies are needed to assess safety and efficacy of different probiotic formulations, followed by large-scale studies to assess utility in infection control and medical practice.

Abstract
Traditionally, probiotic microorganisms are isolated from human and animal intestinal microbiota. However, the demand for diversification of biofunctional products has driven the search for new sources of probiotic candidates, such as fermented foods and vegetables. The present study found that strains isolated from the fermentation of fine cocoa from southern Bahia have biotechnological potential for use as a probiotic, since they showed capacity for self-aggregation and co-aggregation, antimicrobial activity against intestinal pathogens and resistance to gastrointestinal transits. Scores of importance for each property were established in order to more accurately assess the probiotic potential of the strains. The tests carried out contemplate the criteria previously established for the selection of probiotic candidates.

Abstract
Probiotics play a significant role in functional foods. Heat stress and dehydration are the two principal mechanisms leading to inactivation and loss of probiotics viability in its production. There is a need to develop an industrial organism to withstand higher temperatures during its processing and storage. This current study aims to develop thermotolerant strains of Lacticaseibacillus casei N (N) and Lactobacillus helveticus NRRL B-4526 (H) by acclimatizing the wild-type strains to the higher temperature of 45 °C by adaptive laboratory evolution. A two-fold increase in biomass was observed in both acclimatized strains up to the 200th generation, which subsequently remained stable after 500 generations. The morphological change of these acclimatized strains was observed under scanning electron microscopy. Also, there was an increase in probiotic attributes of these acclimatized strains compared to their wild-types. Among two acclimatized strains, L. casei N-45 had shown higher tolerance in the acidic pH 3.0 (89.31%), the bile of 0.3% (84.45%), simulated gastric juice (79.12%), and simulated intestinal juice (73.86%). There was also an increase in salt tolerance (NaCl), radical scavenging activity, autoaggregation, coaggregation, and hydrophobicity of these adapted strains. The total protein profiling using 2D gel electrophoresis reveals the differences in protein expressions between wild-type and acclimatized strains. Specific protein spots from acclimatized strains of H-45 and N-45 were further subjected to MALDI-TOF MS/MS. Some of the identified proteins were recognized to play a role in RNA chaperones and protein synthesis during stress conditions.

Abstract
Biologically active peptides in milk proteins can be used as effective dietary supplements for management of bone-associated issues including osteoporosis. A bioactive peptide derived from milk, viz. VLPVPQK/PepC, has been validated previously from our lab for its osteoanabolic action. In this study, we report 14 novel variants of PepC, designed in silico, based on the structure-activity relationship, aiming to enhance its osteogenic effect that holds tremendous therapeutic utility for bone-related injuries. PepC was computationally modified at seven positions of its original sequence, resulting in 14 modified synthetic peptides for functional predictions and in vitro assessment by comparative analysis of modified peptides by PepC for improved ability in osteogenic functional assays (proliferation potential, antioxidant ability, gene and protein expression, cytotoxic effect, bone mineralization) using calvarial osteoblasts. For most peptides with the highest Peptide7 response relative to PepC (p < 0.05), enhanced osteoanabolic response was observed. Further observations on Peptide7 have therefore been investigated in depth (qPCR, immunoblotting, LCMS/MS, and PCA analysis). Peptide7 displayed a rise in the expression of osteogenes (Osterix, Opg, Bmp2, and Runx2, p < 0.05) and protein (Runx2 and Bmp2, p < 0.05). Besides, LCMS/MS findings suggest Peptide7 escapes intestinal peptidases degradation. Experimental evidence supports an improved osteological reaction to newly modified peptides and hence exploitation in the preparation of functional foods or supplements.

Abstract
Nine strains of Lactiplantibacillus plantarum and one strain of Lacticaseibacillus paracasei that were recently isolated from prickly pears, fresh figs and blackberries, which are traditionally and largely consumed fruits in Kabylia (north of Algeria), were studied here for their antagonism and antioxidant properties as well as for production of exopolysaccharides. With respect to their inhibitory properties, these strains were tested against three food representative pathogens including Escherichia coli ATCC 8739, Staphylococcus aureus 2S6 and Listeria monocytogenes 162. The antagonism of these pathogens was attributable to lactic acid production, present in the cell free supernatant, at concentrations ranging from 9 to 16.74 g/L. The anti-adhesive properties observed on polystyrene or eukaryotic Caco-2 cells were exerted in a strain dependent-manner. Indeed, the scores obtained ranged from 27% to 75% for S. aureus 2S6, 54% to 95% for L. monocytogenes 162, and 50% to 97% for E. coli ATCC 8739. The co-aggregation of these Lactobacillus strains with the aforementioned target bacteria appeared to be exerted in a strain-dependent manner, with noticeably the upmost rate for Lb. paracasei FB1 on S. aureus 2S6. Interestingly, these novel Lactobacillus strains were able to produce a large amount (315.55 to 483.22 mg/L) of exopolysaccharides, and showed a significant scavenging activity on the 2,2-di-phényl-2-picrylhydrazyle (DPPH) synthetic free radical with rates of 51% to 56%. Of note, the highest antioxidant activity was observed for Lb. paracasei FB1 using the culture supernatants, intact cells or the intracellular extract. The statistical analysis of these data using the principal component analysis (ACP) enabled us to establish three distinct clusters with potential applications as bioprotective and/or probiotic agents, following further evaluation.

Abstract
The present study aimed to analyze the colonization potential of indigenous probiotic strains and to assess their effects on physiology of Caenorhabditis elegans. The protective effect of probiotics was evaluated in terms of increase in life span of the worm through colonization in the intestine. A total of 15 probiotic cultures were evaluated for their effect on mean life span, pharyngeal pumping, and normal reproduction behavior in the worms. The chemotactic behavior in terms of binary choice index was also evaluated. The adherence and colonization of the intestine of the worm by probiotics were monitored at different time intervals by enumerating the microbial population and fluorescent microscopic observations. The survival analysis-based Kaplan-Meier method indicated that the probiotic cultures increased the survival probability as compared to control strain E. coli OP50. There was no effect of feeding probiotics on physiological responses of the worm such as pharyngeal pumping and reproduction. The principal component analysis (PCA) of the results indicated Lactobacillus plantarum K90 and L. paracasei CD4 as potential probiotics with binary choice index of 0.8 as food preference of C. elegans. The strains exhibit higher adherence and colonization in the gut of worms and increased the life span by 5 days as compared to control E. coli OP50. In conclusion, feeding with probiotic cultures is effective in extending the lifespan of C. elegans; however, the colonization ability differs among the strains.

Abstract
Los alimentos a los que se les añaden probióticos (bacterias benéficas) constituyen uno de los sectores más importantes de los alimentos funcionales. Los productos lácteos son los principales vehículos para estas bacterias que producen un efecto benéfico a la salud, cuando se consumen vivas y en cantidades suficientes para adherirse al colon. Sin embargo, cada día crece el interés por desarrollar alimentos no lácteos como vehículo para probióticos. Los productos de origen vegetal son una buena alternativa para estas innovaciones. Tienen la ventaja de que son muy aceptados y accesibles para la población. Adicionalmente, representan una alternativa de consumo para poblaciones con dietas restringidas. Sin embargo, la incorporación de probióticos a estos productos requiere considerar varios criterios y vencer retos tecnológicos con la finalidad de conservarlos funcionalmente activos.

Abstract
The present study investigated skimmed milk and alginate-based encapsulation for protection of a probiotic strain, Lactobacillus gastricus BTM7 during storage and exposure to simulated gastrointestinal conditions. The investigations have revealed that coating with skimmed milk and alginate in a ratio of 1:1 resulted in highest encapsulation efficiency of 94% (p < 0.05) with approximately 1 log reduction in viable cell count and 90% release of encapsulated cells in 90 min. This formulation resulted in 5-fold higher survival of bacteria during storage at refrigeration for 21 days (p < 0.05). The encapsulation of L. gastricus BTM7 provided better protection at the pH of gastric juice or pancreatic conditions with 4- and 9-fold increase in survivability after 2 h of incubation. The principal component analysis (PCA) revealed the potential of skimmed milk supplementation to alginate (1:1) to enhance survival of probiotic strain under refrigerated storage, a process that can be safely incorporated into dairy products.

Abstract
The present study reports the potential of newly isolated calcite precipitating bacteria isolated from alluvial soil to improve the strength and durability of concrete. A total of sixteen samples of alluvial soil and sewage were collected from the different locations of province Solan (India). For isolation, enrichment culture technique was used to enrich calcite precipitating strains in Urea broth. After enrichment, fourteen distinct bacterial strains were obtained on Urea agar. Based on qualitative and quantitative screening for urease activity, five isolates were obtained possessing higher calcite formation and urease activities (38-77 μmhos/cm) as compared with standard strain of Bacillus megaterium MTCC 1684 (77 μmhos/cm). An isolate I13 identified as Lysinibacillus sp. was selected for self healing property in the concrete mix of M20. An improved compressive strength of 1.5 fold was observed in concrete samples amended with Lysinibacillus sp. over the concrete amended with B. megaterium MTCC 1684 after 28 days of curing. The higher calcite precipitation activity was indicated in Lysinibacillus sp. by FE-SEM micrographs and EDX analysis.
