To screen environmental Bacillus strains for detection of genes encoding the enzymes involved in biosurfactant synthesis and to evaluate their products e.g. surfactin, iturin fengycin.The taxonomic identification isolated from environment was performed by Microgene ID panel GEN III Biolog system. The polymerase chain reaction (PCR) strategy screening set up. Liquid chromatography-mass spectrometry (LC-MS/MS) method used lipopeptides (LPs). All studied exhibited presence srfAA gene produced...
Urinary tract infections are a common disease in humans. Therefore, new methods needed to destroy biofilms that formed by uropathogens. Iturin A lipopeptides (LPs) C14 and C15 potent biosurfactants synthetized the Bacillus subtilis I'1a strain. The biological activity of extracted LPs was confirmed examining extracts from cultures against uropathogenic bacteria had been isolated on urinary catheters. Compared with DSM 3257, which produce surfactin at relatively low level, extract obtained...
The aim of this study was to investigate the antimicrobial effect lipopeptide biosurfactants from surfactin, iturin and fengycin families, synthesised by Bacillus subtilis I'1a strain, on uropathogenic bacteria, including effects planktonic growth, processes biofilm formation dislodging. Antimicrobial activity tested against 32 strains belonging 12 different species Gram-negative Gram-positive bacteria. sensitivity 25 bacterial B. filtrate confirmed an agar diffusion assay. None seemed be...
In this study, culture supernatnats of Bacillus subtilis T-1 growing on brewery effluents and molasses was used for silver nanoparticles (Ag-NPs) synthesis. The biosurfactant production B. confirmed by the detection genes in genome identification product supernatants. synthesis surfactin (sfp, srfAA) iturin (ituC) were noted PCR reactions. Also, examined supernatants presence C13, C14 C15 homologues with sodiated molecules [M + Na](+) at m/z 1030, 1044 1058 using LC/MS/MS analysis. formation...
The waste of rapeseed press cake (WRPC), obtained after the preparation microbial culture medium, was investigated in a batch system as an adsorbent malachite green (MG). effects contact time, temperature, initial dye concentration and dosage were examined using MG aqueous solutions pH 6.5. highest sorption observed 180 min solution containing 50 mg/L 2.5 WRPC. Equilibrium isotherm data described by Langmuir, Freundlich Dubinin-Radushkevich models. Langmuir expression found to provide best...
In this work, the comparison of physical properties silver nanoparticles (AgNPs) obtained via reduction nitrate (AgNO3) in biological and chemical (model) syntheses supplemented with biosurfactant surfactin is described. studies, two strains Bacillus subtilis (denoted T'1 I'1a) were used. The synthesis AgNPs was performed using supernatants from cultures bacteria growing on brewery effluents, molasses, Luria–Bretani (LB) medium. model experiments, ascorbic acid served as reductant; acted...
The amounts of anthropogenic pollutants, e.g., microplastics (MPs) and pesticides, in terrestrial aquatic ecosystems have been increasing. aim this study was to assess the influence MPs on removal herbicides (metolachlor, MET; 2,4-dichlorophenoxyacetic acid, 2,4-D) production biosurfactants (surfactin iturin) by Bacillus sp. Kol L6 active against Fusarium culmorum. results showed that eliminated 40-55% MET 2,4-D from liquid cultures, but process inhibited presence MPs. Although pollutants...
The development of the textile industry has negative effects on natural environment. Cotton cultivation, dyeing fabrics, washing, and finishing require a lot water energy use many chemicals. One most dangerous pollutants generated by is dyes. Most them are characterized complex chemical structure an unfavorable impact Especially azo dyes, whose decomposition bacteria may lead to formation carcinogenic aromatic amines raise concern. Using metabolic potential microorganisms that biodegrade...
Although it is known that microplastics (MPs) in soils cause a threat to this complex environment, the actual effects of MPs on soil microorganisms and their catabolic activities, particularly with biodegradation herbicides, remain unclear. Hence, objective study was investigate simultaneous presence metolachlor low-density polyethylene (LDPE) growth inhibition adaptive responses Trichoderma harzianum microcosms. Using ergosterol content as an indicator fungal biomass, observed alone had...
This study aimed to evaluate how the combined presence of synthetic fungicide azoxystrobin (AZ) and biosurfactant-producing Bacillus sp. Kol B3 influences growth phytopathogenic fungus Fusarium sambucinum IM 6525. The results showed a noticeable increase in antifungal effectiveness when biotic abiotic agents were combined. effect manifested across diverse parameters, including fungal inhibition, changes hyphae morphology, membrane permeability levels intracellular reactive oxygen species...
In this study, culture supernatant of Bacillus subtilis KP7 growing on liquid LB medium consisted 2 % molasses was used for calcium carbonate synthesis. Synthesis the structures performed in a reactor by mixing CaCl2 and Na2CO3 solutions at 25°C. The particles were characterized optical microscopy, FTIR XRD analysis. addition, size distribution value zeta potential determined. It observed that properties obtained depend amount. smallest crystals pure calcite with disordered structure when...
