“…The relative carbohydrates content for the fermentation supernatant was determined using the phenol–sulfuric acid method. The content of reducing sugars was determined by 3,5-dinitrosalicylic acid (DNS) colorimetric method [ 23 ]. The molecular weight (Mw) distribution was determined using high performance gel permeation chromatography (HPGPC) on an Agilent 1200 series instrument equipped with a TSK G4000PW XL column (7.8 × 300 mm) and refractive index detector.…”

In the present study, four Bacteroides species that could degrade Fuzhuan brick tea polysaccharide-3 (FBTPS-3) were isolated from human feces and identified to be Bacteroides ovatus, B. uniformis, B. fragilis and B. thetaiotaomicron. The four Bacteroides species showed growth on FBTPS-3 as the carbon source, and B. ovatus showed the best capability for utilizing FBTPS-3 among the four species since B. ovatus could utilize more FBTPS-3 during 24 h fermentation. Moreover, the four Bacteroides species could metabolize FBTPS-3 and promote the production of acetic, propionic and isovaleric acids. Transcriptome analysis of B. ovatus revealed that 602 genes were up-regulated by FBTPS-3, including two carbohydrate-active enzyme clusters and four polysaccharide utilization loci (PULs). The PUL 1 contained GH28 family that could hydrolyze rhamnogalacturonan and other pectic substrates, which was in line with our previous work that rhamnose and galacturonic acid were the main component monosaccharides of FBTPS-3. Collectively, the results suggested that FBTPS-3 could be utilized by Bacteroides spp., and it might be developed as a promising prebiotic targeting Bacteroidetes in intestinal environment.

“…What is more, the use of plant extract can hinder the aggregation of the synthesized metal nanoparticles and control their particle sizes [7]. Many research articles reported the synthesis of Ag-NPs using plant extracts such as Citrullus colocynthis [8], Alternanthera dentata [9], Rhododedendron dauricam [10], Acalypha indica [11], Artemisia nilagirica [12], Boswellia ovalifoliolata [13], Nelumbo nucifera [14], Desmodium triflorum [15], Hibiscus cannabinus [16], Sesuvium portulacastrum [17], Stigmaphyllon littorale [18], Trachyspermum copticum [19] and Rosa rugosa [20].…”

The present study reveals the efficiency of the fruit extract of Ribes nigrum in the green synthesis of silver nanoparticles (Ag-NPs). Biosynthesized Ag-NPs were characterized by UV-vis, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and atomic force microscopy (AFM). The nanoparticles were found to be 5–10 nm. In some places, the particles were agglomerated. The nanoparticles showed strong bactericidal activity and fungicidal activity against dermatophytes Trichophyton rubrum ATCC 28188. Moreover, the A549 and CCD39Lu cells under the influence of the highest concentration of nanoparticles synthesized using the fruit extract of Ribes nigrum showed the maximum mortality. Also, the results indicate that Ag-NPs synthesized using the fruit extract of Ribes nigrum exhibit efficiency in therapy of human non-small cell lung cancer A549.
