This study deals with the ability of probiotic bacteria to ferment prebiotics in vitro estimate prebiotic activity score and index based on specific substrates strains. Five were isolated from commercial products their fermentation capability three was assessed. Growth kinetics probiotics showed that all them able use as carbon sources. Mostly grew faster Frutafit Oligomate 55 than lactulose. The concepts introduced evaluate performance every each prebiotic; accordingly, highest values for...
Selenium nanoparticles (SeNPs) are gaining importance in the food and medical fields due to their antibacterial properties. The microbial inhibition of these kinds particles has been tested a wide range Gram (+) (−) pathogenic bacteria. When SeNPs synthesized by biological methods, they called biogenic SeNPs, which have negative charge caused interaction between surface capping layer (bioorganic material), producing high stability. This review is focused on synthesis bacteria summarizes main...
Amaranthus hypochondriacus spp. is a commonly grown cereal in Latin America, known for its high protein content. The objective of this study was to separate and identify bioactive peptides found amaranth seeds through enzymatically-assisted hydrolysis using alcalase flavourzyme. Hydrolysis carried out each enzyme separately compared two-step continuous process where both enzymes were combined. biological activity the resulting three hydrolysates analyzed, finding, general, higher potential...
The increasing demand for functional foods has led to an interest in fermentation processes that enhance the production of antioxidant peptides. This study aimed perform a bibliometric analysis lactic acid bacteria (LAB) used wheat produce To achieve this, data from 2010 2023 were gathered Web Science® database, focusing on publications related LAB, proteins, and search results analyzed using bibliometrix R package, which allowed in-depth examination research trends, collaborations,...
Fermentation has shown to be an effective technique in bioactive peptides release. That is why this study antihypertensive, antithrombotic, and antioxidant activity was evaluated during amaranth proteins fermentation with Lactobacillus casei Shirota Streptococcus thermophilus 54102 mono combined culture. During increase of free amine groups observed, no statistical differences among monocultures were shown, getting higher concentration This related antihypertensive activities, where the...
Probiotics and prebiotics are among the most important functional food ingredients worldwide. The proven benefits of such to human health have encouraged development foods containing both probiotics prebiotics. In this work, production antimicrobial compounds coupled uptake commercial by probiotic bacteria was investigated.The studied were able take up prebiotic carbohydrates same or higher extent than that observed for lactose (control carbohydrate). growth antimicrobials as short-chain...
The aim of this research was to determine the physicochemical properties, microbial counts and aflatoxin M1 (AFM1) levels thermoultrasonicated, pasteurized untreated milk (control) at days 1, 7 14 storage. Thermoultrasound treatment performed a rate 20 kHz for 10 or 15 min 95% amplitude on homogenized non-homogenized samples. Results showed that most parameters were within Mexican norms established milk. Ultrasound reduced solids precipitation (p < 0.05) in unhomogenized during storage as...
The health benefits attributed to probiotics generate interest in the search of competent strains adapted several ecological niches, especially those related traditional beverages and foods each country. Pineapple tepache, a Mexican fermented beverage, was used for isolation lactic acid bacteria with probiotic potential, one which withstood vitro tests. isolated strain AB-05, exhibited tested functional properties, designated as Lactobacillus pentosus ABHEAU-05. sequence registered GenBank...
Selenium is an essential micronutrient and has been shown to have antioxidant effect. This can prevent different diseases such as coronary illness or cancer. Its deficiency generates neuromuscular disorders, which why a recommended daily intake for humans of 55 μg/day proposed but it not always covered. integrated selenoaminoacids glutathione peroxidases, are enzymes involved in redox reactions. Some yeast capable introducing inorganic selenium into the polypeptide chains ribosome later...
The secondary structure of Kluyveromyces lactis β-galactosidase was determined by circular dichroism. It is mainly a β-type protein, having 22% β-turns, 14% parallel β-sheet, 25% antiparallel 34% unordered structure, and only 5% α-helix. structure−activity relationship as function the pH also studied. conditions leading to highest content (100% ellipticity) enzyme found at 7.0; 6.5−7.0, percent ellipticity decreased slightly, suggesting little structural change, but activity significantly,...
The highest enzymatic extraction of covalent linked chlorogenic (36.1%) and caffeic (CA) (33%) acids from coffee pulp (CP) was achieved by solid‐state fermentation with a mixture three extracts produced Aspergillus tamarii , Rhizomucor pusillus Trametes sp. Enzyme were in practical inexpensive way. Synergistic effects on the yield observed when more than one enzyme extract used. In addition, biotransformation acid (ChA) niger C23308 studied. Equimolar transformation ChA into CA quinic (QA)...
Selenium is an essential trace element in human health. However, it has been considered a widespread selenium deficiency worldwide, although the recommended daily intake very low (55 μg per day). Strategies have implemented to comply with doses, for example, through bioavailable such as selenoamino acids. Thus, this research aimed elaborate on beer-type fermented beverage produced previously selenized Saccharomyces boulardii. For this, yeast was by adding minimum inhibitory concentration of...
Health benefits of probiotics and production inhibitors angiotensin converting enzyme (ACE) released during milk fermentation are well known. That is why in this investigation the proteolytic profile ACE inhibitory capacity peptide fractions from protein hydrolysis processes was analyzed. Milk carried out inoculating 106 CFU L. rhamnosus GG, S. thermophilus SY-102 with both bacteria. The determined using: TNBS, SDS-PAGE SEC-HPLC techniques. In vitro inhibition measured. pH 4.5 reached at 56...
In order to achieve a higher added value of two galactomannan-containing wastes, copra paste and spent coffee from the soluble industry (SCW), solid substrate fermentation (SSF) was used. Filamentous fungi Aspergillus oryzae A niger were used evaluate feasibility producing β-mannanase by SSF. 23 factorial design select best interaction among fungi, substrates times. The treatment ‘A niger–copra–2.5 days’ produced significantly (p < 0.05) activity, having five different isoforms enzyme, one...
