| bacterial communities of fresh goat meat packaged in modified atmosphere. | the objective of this work was to study the growth and development of fortuitous flora and food pathogens in fresh goat meat packaged under modified atmospheres containing two different concentrations of co2. meat samples were stored at 10 °c under two different modified-atmosphere packing (map) conditions: treatment a had 45% co2 + 20% o2 + 35% n2 and treatment b had 20% co2 + 55% o2 + 25% n2. during 14 days of storage, counts of each bacterial group and dominant species identification by 16s r ... | 2017 | 28400020 |
| microbial cell-free extracts affect the biochemical characteristics and sensorial quality of sourdough bread. | this study aimed to improve the sensorial quality of sourdough wheat bread by the addition of cell-free enzyme extracts (cfes) from lactobacillus sanfranciscensis (sf), hafnia alvei (hf) and debaryomyces hansenii (dh). cfes were suitable sources of peptidases, glutamate dehydrogenase and cystathionine γ-lyase. the concentration of free amino acids (faa) in the sourdoughs containing cfes was higher than the control sourdough, produced without addition of cfes. the community-level catabolic profil ... | 2017 | 28763982 |
| microorganisms of the intestinal microbiota of oncorhynchus mykiss produce antagonistic substances against bacteria contaminating food and causing disease in humans. | the objective was to analyse the antibacterial ability of members of the intestinal microbiota of oncorhynchus mykiss specimens on several bacterial target strains that contaminate food and cause disease in humans. bacterial colonies from an intestinal portion of the 20 specimens of o. mykiss were obtained in different culture media. several of the colonies showed antibacterial action on different target strains. the bacterial species with the highest antagonistic capacity were hafnia alvei and ... | 2017 | 28713788 |
| inhibition of hafnia alvei h4 biofilm formation by the food additive dihydrocoumarin. | quorum sensing (qs) is an intercellular signaling and gene regulatory mechanism that is implicated in food spoilage caused by bacteria. thus, blocking qs may suppress qs-controlled phenotypes of these bacteria that are responsible for food spoilage. biofilm formation is closely related to bacterial infection, and it is also a major mechanism responsible for the increased resistance of biofilm-associated bacteria to antimicrobial drugs. food spoilage and biofilm formation caused by food-related b ... | 2017 | 28402186 |
| honeybee (apis mellifera)-associated bacterial community affected by american foulbrood: detection of paenibacillus larvae via microbiome analysis. | honeybee (apis mellifera l.) workers act as passive vectors of paenibacillus larvae spores, which cause the quarantine disease american foulbrood (afb). we assessed the relative proportions of p. larvae within the honeybee microbiome using metabarcoding analysis of the 16 s rrna gene. the microbiome was analyzed in workers outside of the afb zone (control - afb0), in workers from asymptomatic colonies in an afb apiary (afb1), and in workers from colonies exhibiting clinical afb symptoms (afb2). ... | 2017 | 28698604 |
| multiple microbial cell-free extracts improve the microbiological, biochemical and sensory features of ewes' milk cheese. | this study used cell-free enzyme (cfe) extracts from lactobacillus casei, hafnia alvei, debaryomyces hansenii and saccharomyces cerevisiae to condition or accelerate pecorino-type cheese ripening. compositional, microbiological, and biochemical analyses were performed, and volatile and sensory profiles were obtained. lactobacilli and cocci increased during ripening, especially in cheeses containing cfe from l. casei, h. alvei and d. hansenii (lhd-c) and l. casei, h. alvei and s. cerevisiae (lhs- ... | 2017 | 28576361 |
| complete genome sequence of a commensal bacterium, hafnia alvei cba7124, isolated from human feces. | members of the genus hafnia have been isolated from the feces of mammals, birds, reptiles, and fish, as well as from soil, water, sewage, and foods. hafnia alvei is an opportunistic pathogen that has been implicated in intestinal and extraintestinal infections in humans. however, its pathogenicity is still unclear. in this study, we isolated h. alvei from human feces and performed sequencing as well as comparative genomic analysis to better understand its pathogenicity. | 2017 | 28770009 |
