Bacillus amyloliquefaciens LZN01 shows antagonistic behaviour against Fusarium oxysporum f. sp. niveum (Fon). This study aimed to analyze the antifungal activity and functional components of cell-free supernatant from B. that inhibited Fon growth. The results showed (CFS) death phase had stronger compared those exponential stage stationary phase. analyses scanning transmission electron microscopy demonstrated treatment with CFS led cellular morphological changes, including concave formations...
Summary Myriocin, which is produced by Bacillus amyloliquefaciens LZN01, can inhibit the growth of Fusarium oxysporum f. sp. niveum (Fon). In present study, antifungal mechanism myriocin against Fon was investigated with a focus on effects cell membrane. Myriocin decreased membrane fluidity and destroyed integrity Fon. Significant microscopic morphological changes, including conidial shrinkage, appearance larger vacuoles inhomogeneity electron density, were observed in myriocin‐treated...
Abstract Dibutyl phthalate (DBP) is well known as a high-priority pollutant. This study explored the impacts of DBP on metabolic pathways microbes in black soils short term (20 days). The results showed that microbial communities were changed with DBP. In nitrogen cycling, abundances genes elevated by contamination facilitated 3′-phosphoadenosine-5′-phosphosulfate (PAPS) formation, and gene flux sulfate metabolism was increased. total ABC transporters monosaccharide-transporting ATPases MalK...
The poly(butylene carbonate) (PBC)/poly(lactic acid) (PLA)/chitosan (CS) blend nanofibre membranes have been prepared by electrospinning. Trifluoroacetic acid was found to be the best co-solvent for PBC/PLA/CS blend. microstructure studied scanning electron microscopy and showed good fibre diameter distribution when CS content 0.08%. As of increases, fibres became finer. Fourier transform infrared spectrometer shows that there no chemical reaction between PBC PLA, successfully added PBC/PLA....
The growth of watermelon is often threatened by Fusarium oxysporum f. sp. niveum (Fon) in successively monocultured soil, which results economic loss. objective this study was to investigate the effect D123 wheat as a companion crop on soil enzyme activities, microbial biomass and communities rhizosphere explore relationship between incidence wilt caused Fon. showed that activities polyphenol oxidase, urease invertase were increased, nitrogen (MBN) phosphorus (MBP) significantly ratio...
Design and preparation of gels with excellent mechanical properties has garnered wide interest at present. In this paper, polyvinyl alcohol (PVA)-tannic acid (TA) exceptional is documented. The crystallization zone hydrogen bonding acted as physical crosslinkages fabricated by a combination freeze-thaw treatment tannic compound. effect on prepared PVA-TA was investigated analyzed. When the mass fraction PVA 20.0 wt% soaking time 12 h in aqueous solution, tensile strength elongation break gel...
The surface of food wrapping paper is coated with octenylsuccinic anhydride (OSA)‐modified cassava starch to develop packaging high waterproofing and low grease permeability. Oxidized modified using various concentrations OSA, esterification confirmed by Fourier transform infrared spectroscopy (FT‐IR) 1 H nuclear magnetic resonance ( NMR). To explore the effects OSA concentration, content, incubation time, coating rate on oil resistance hydrophobicity, water barrier properties are quantified...
Abstract Background Myriocin is a natural product with antifungal activity and derived from Bacillus amyloliquefaciens LZN01. Our previous work demonstrated that myriocin can inhibit the growth of Fusarium oxysporum f. sp. niveum (Fon) by inducing membrane damage. In this study, actions against Fon were investigated focus on effects intracellular molecules. Results Analysis DNA binding fluorescence spectra interact dsDNA cells. The intracellular-targeted mechanism action was also supported...
The plant cytoskeleton forms a stereoscopic network that regulates cell morphogenesis. also provides tracks for trafficking of vesicles to the target membrane. Fusion with membrane is promoted by SNARE proteins, etc. vesicle-SNARE, Sec22, between ER and Golgi in yeast mammals. Arabidopsis AtSEC22 might regulate early secretion essential gametophyte development. However, role development unclear. To clarify regulation development, we isolated an knock-down mutant, atsec22-4 , found...
Here, we report the complete genome of strain WB, isolated from rhizosphere a healthy watermelon Fusarium wilt diseased field, which possesses antifungal activity against oxysporum f. sp. niveum (Fon) and reduces incidence in watermelon.Genome sequences were determined using Illumina HiSeq PacBio platforms. Genome assembly was performed by Unicycler software. Gene clusters responsible for secondary metabolite biosynthesis predicted antiSMASH.The size 3 896 799 base pairs, there 3977 coding...
The bacterial strain LZN01 is a potential biocontrol agent that produces myriocin and inhibits the growth of Fusarium oxysporum f. sp. niveum (Fon). To characterize LZN01, Illumina HiSeq + PacBio sequencing platform was used to sequence its genome. Unicycler software perform genome assembly antiSMASH predict gene clusters responsible for secondary metabolite biosynthesis. comprises 3973236 bp has 46.52% G C content. Genome annotation predicts 4031 coding DNA sequences (CDSs), 27 rRNAs 86...
Our previous findings indicated that Bacillus velezensis WB could control Fusarium wilt by changing the structure of microbial community in watermelon rhizosphere. However, there are few studies on its mechanism pathogen resistance watermelon. Therefore, this study, we determined B. WB-induced systemic against through glasshouse pot experiments.
It could be shown that atrazine bound to microbes DNA in black soil by using ethidium bromide (EB) as a fluorescence probe. To study the interaction between and soil, spectral absorption analysis were adopted. Atrazine, when DNA, showed hyperchromic red shift spectra quenching (>50%) spectra, which indicated intercalation. The effect of phosphate ion there electrostatic attractions with anionic sugar‐phosphate backbone DNA. ratio plots “fluorescence intensities absence” presence quencher”...
Abstract In this study, the antifungal mechanism of secondary metabolites from WB strain against Fusarium oxysporum f. sp. niveum (Fon) was investigated. The induced accumulation reactive oxygen species in Fon hyphae and caused morphological changes, including surface subsidence shrinkage deformation. cell-free supernatants (CFSs) treatment a significant increase superoxide dismutase, catalase, peroxidase glutathione reductase activities contents soluble protein malondialdehyde....
