Punicalagin, one of the main active compounds in pomegranate peel, has been reported to possess many properties, including antioxidant, antimicrobial, antiviral, and immunosuppressive activities. The aim this study was investigate antibacterial effect punicalagin against Staphylococcus aureus possible mode action. Growth inhibition activity examined by agar diffusion method. Then dilution method adopted determine minimum inhibitory concentration (MIC). effects on cell membrane were assessed...

Punicalagin, an essential component of pomegranate rind, has been demonstrated to possess antimicrobial activity against several food-borne pathogens, but its on the virulence pathogens and anti-quorum-sensing (anti-QS) potential have rarely reported. This study investigated efficacy subinhibitory concentrations punicalagin Salmonella factors QS systems. A broth microdilution method was used determine MICs for 10 strains. Motility assay quantitative reverse transcription (RT)-PCR were...

Phage ecology has attracted increasing attention in recent years. Fermented foods have rich and diverse microbial communities, which are not only the creators of unique flavors food, but also good hosts for bacteriophages. However, at present, much is known about bacterial fungal communities their functions fermented foods, little bacteriophages that inhabit bacteria. This article reviews findings on phage diversity highlighting how these organisms influence relate to dynamics foods. The...

Apiotrichum is a diverse anamorphic basidiomycetous yeast genus, and its mitogenome characterization has not been revealed. In this study, we assembled two mitogenomes compared them with from Agaricomycotina, Pucciniomycotina Ustilaginomycotina. The of gracile A. gamsii comprised circular DNA molecules, sizes 34,648 bp 38,096 bp, respectively. Intronic regions were found contributed the most to size expansion mitogenome. Comparative mitogenomic analysis revealed that 6.85-38.89% nucleotides...

The animal gastrointestinal tract contains a complex community of microbes, whose composition ultimately reflects the co-evolution microorganisms with their host and diet adopted by host. Although importance gut microbiota humans has been well demonstrated, there is paucity research regarding non-human primates (NHPs), especially herbivorous NHPs.In this study, an analysis 97,942 pyrosequencing reads generated from Rhinopithecus bieti fecal DNA extracts was performed to help better...

In the present study, we assembled and analyzed mitogenomes of two Ramaria species. The cfr. rubripermanens R. rubella were circularized, with sizes 126,497 bp 143,271 bp, respectively. Comparative mitogenome analysis showed that intron region contributed most (contribution rate, 43.74%) to size variations mitogenomes. genetic contents, gene length, tRNAs, codon usages varied greatly. addition, evolutionary rates different core protein coding genes (PCGs) in Phallomycetidae varied. We...

Xylan is the main component of hemicellulose. Complete hydrolysis xylan requires synergistically acting xylanases, such as β-d-xylosidases. Salt-tolerant β-d-xylosidases have significant application benefits, but few reports explored critical amino acids affecting salt tolerance xylosidases. Herein, site-directed mutation was used to demonstrate that negative electrostatic potentials generated by 19 acidic residues in loop regions structural surface positively correlated with improved GH39...

Pomegranate rind has been found to inhibit numerous pathogens, mostly attributed its tannin fraction. The present study was conducted investigate the quorum sensing (QS) inhibition effect of tannin-rich fraction from pomegranate (TFPR) by using an indicator strain Chromobacterium violaceum. Meanwhile, on biofilm formation and motility Escherichia coli evaluated. It shown that TFPR inhibited QS-regulated violacein pigment production. Biofilm E. were also hindered TFPR. Transcriptional...

In this study, the synergistic effect of vancomycin, a cell wall synthesis inhibitor, and ultrasound-targeted microbubble destruction (UTMD), on viability Staphylococcus epidermidis, embedded in biofilm, was investigated. Biofilms are leading causes antibiotic-resistant bacterial infections medical implants prosthetics worldwide. The nature biofilm-embedded pathogens poses critical challenge to community. Previously, studies have demonstrated efficacy using ultrasound waves UTMD...

Xylanases have been applied in many industrial fields. To improve the activity and thermostability of xylanase CDBFV from Neocallimastix patriciarum (GenBank accession no. KP691331), submodule C2 hyperthermophilic CBM9_1-2 was inserted into N- and/or C-terminal regions protein (producing C2-CDBFV, CDBFV-C2, C2-CDBFV-C2) by genetic engineering. hybrid proteins were successfully expressed Escherichia coli BL21 (DE3). Enzymatic property analysis indicates that had a significant effect on...
