Animals frequently use metabolites produced by symbiotic bacteria as agents against pathogens and parasites. Secretions from the preen gland of birds are used for this purpose, although its chemicals apparently themselves. European hoopoes Upupa epops green woodhoopoes Phoeniculus purpureus harbour in uropygial that might be partly responsible chemical composition secretions. Here we investigate antimicrobial activity volatile fraction hoopoe secretions, and, means experimental antibiotic...
To determine the effects of outer membrane (OM) permeabilizing agents on antimicrobial activity enterocin AS-48 against Escherichia coli O157:H7 CECT 4783 strain in buffer and apple juice.We determined influence pH, EDTA, sodium tripolyphosphate (STPP) heat E. sensitivity to juice. Enterocin was not active intact cells at neutral pH. However, sublethally injured by OM (EDTA, STPP, pH 5, 8.6 heat) became sensitive AS-48, decreasing amount bacteriocin required for inhibition 4783.The results...
ABSTRACT Exploring processes of coevolution microorganisms and their hosts is a new imperative for life sciences. If bacteria protect against pathogens, mechanisms facilitating the intergenerational transmission such will be strongly selected by evolution. By disentangling diversity bacterial strains from uropygium hoopoes ( Upupa epops ) due to genetic relatedness or common environment, we explored importance horizontal (from environment) vertical parents) acquisition...
Control of the enterotoxigenic Staphylococcus aureus CECT 976 strain by enterocin AS-48 in laboratory cultures, and behaviour activity presence food preservatives.Enterocin shows inhibitory on majority species tested. This has a bactericidal bacteriolytic mode action S. 976, selected for this study its character (SEA production). The effect was pH temperature dependent, higher at 5. minimum concentration (MBC) AS-48, decreased from 15 microg ml(-1) 37 degrees C to 10 C. Sublethally injured...
A substantial quantity of solid fish by-products is generated during the processing. These offer an intriguing opportunity as a source high added-value compounds, including digestive proteases. Indeed, trypsin one most beneficial and useful biomolecules that can be recovered from wastes. Additionally, protein hydrolysates have emerged valuable abundant high-quality bioactive molecules, which efficiently through enzymatic hydrolysis. This study aims to provide insights into extraction...
To determine the effectiveness of enterocin AS-48 on Staphylococcus aureus CECT 976 in combination with chemical preservatives at acidic and neutral pH.At pH 4.5, activity increases presence lactic acid (1.0%), acetic (0.5% 1.0%), citric (0.3% 0.6%). This synergistic effect has also been observed during first 8 h incubation benzoate (0.06% 0.12%) sorbate (2% 3%). Interestingly, 7, lactate (1%) inhibitory AS-48, reducing S. population by 6 log units compared control culture. At pH,...
This study aimed to assess the probiotic potential of Enterococcus durans F21 and its microencapsulation. Two microencapsulation methods, spray-drying (SD) freeze-drying (FD), were employed using sodium caseinate (Cas) as a cell protectant at concentrations 0.035% 1% two pHs, 3 7. Maltodextrins (MD) served wall material (10%). Microcapsules analysed for viability membrane damage after drying, survival under simulated gastro-intestinal conditions, antimicrobial activity, stability during...
Background and objective: Lactic acid bacteria, used in food processing for a long time, can produce various metabolites during their growth, including bacteriocins. These antimicrobials, as natural bio-preservatives, enhance the safety. The objective of this study was to assess lactic bacteria bacteriocins with anti-listerial activity optimize production recovery process. Material methods: Isolate identified using conventional assays (morphological biochemical characteristics) 16S rRNA gene...
Introduction: For thousands of years, Cannabis sativa has been used for its medical and recreational benefits. Nowadays, there is an increasing interest in the use C. non-psychoactive products/effects to treat certain diseases. This study was conducted examine gastrointestinal effects a sequential ethanolic fraction threshing residues (EFCS). Methods: In vivo vitro approaches were investigate properties EFCS. Antidiarrheal, antibacterial, spasmodic, laxative, antiulcer tested respectively...
