Abstract Background Epidemiology of celiac disease (CD) is increasing. CD mainly presents in early childhood with small intestinal villous atrophy and signs malabsorption. Compared to healthy individuals, patients seemed be characterized by higher numbers Gram-negative bacteria lower Gram-positive bacteria. Results This study aimed at investigating the microbiota metabolome 19 children under gluten-free diet (treated disease, T-CD) 15 non-celiac (HC). PCR-denaturing gradient gel...
Summary Poor iron ( F e) availability in soil represents one of the most important limiting factors agricultural production and is closely linked to physical, chemical biological processes within rhizosphere as a result soil–microorganism–plant interactions. Iron shortage induces several mechanisms organisms, resulting an enhanced release inorganic (such protons) organic (organic acids, carbohydrates, amino phytosiderophores, siderophores, phenolics enzymes) compounds increase solubility...
The equilibrium adsorption and binding of the active toxin from Bacillus thuringiensis subsp. kurstaki, toxic to lepidopteran larvae, humic acids extracted two forest cultivated soils, as well insecticidal activity biodegradation bound toxin, were studied. From 75 85% added was rapidly adsorbed at equilibrium, a constant amount increased with concentration until plateau reached. Differences in total acidity content phenolic groups appeared be primarily responsible for differences amounts...
Equilibrium adsorption and binding of DNA from Bacillus subtilis on humic acids (HA) extracted a forest soil, the capacity bound to transform B. subtilis, resistance degradation by DNase I are reported. Adsorption HA was maximal after 2 4 h at pH 3.0 4.0, respectively. The constant amount (50 μg) increasing concentrations reached plateau with 3 mg No observed when amounts where adsorbed (2 mg). 70 80% tightly two washes 0.1 M NaCl (pH 6.4), double distilled water 5.5), or buffer 4.0). Bound...
ABSTRACT This study aimed at investigating the fecal microbiotas of children with celiac disease (CD) before (U-CD) and after (T-CD) they were fed a gluten-free diet healthy (HC). Brothers or sisters T-CD enrolled as HC. Each group consisted seven children. PCR-denaturing gradient gel electrophoresis (DGGE) analysis V3 universal primers revealed unique profile for each sample. PCR-DGGE group- genus-specific 16S rRNA gene showed that Lactobacillus community U-CD changed significantly, while...
Through metabolic analysis, the present research seeks to reveal defense mechanisms activated by a heavy metals-resistant plant, Sesuvium portulacastrum L. In this regard, shifting metabolisms in plant were investigated different metals-contaminated experimental sites, which 50, 100, 500, 1000, and 5000 m away from man-fabricated sewage dumping lake, with wide range of pollutant concentrations. Heavy metals contaminations contaminated soil their impact on mineral composition microbial...
ABSTRACT Heat stress resistance and response were studied in strains of Lactobacillus plantarum . Stationary-phase cells L. DPC2739 had decimal reduction times ( D values) value was the time that it took to reduce number by 1 log cycle) sterile milk 32.9, 14.7, 7.14 s at 60, 72, 75°C, respectively. When mid-exponential-phase used, values decreased. The temperature increases which caused a 10-fold ranged from 9 20°C, depending on strain. Part cell population treated 72°C for 90 recovered...
Increasing awareness of the problems caused by synthetic agrochemicals, such as chemical fertilizers, pesticides, and herbicides, makes it crucial to discover substitute approaches that can guarantee competitive plant production protect environment while maintaining natural balance in agroecosystems. One leading alternatives is utilizing rhizobacterial strains named growth-promoting rhizobacteria (PGPR). The utilization PGPR-based biofertilizers for advancement sustainability farming...
Abstract Sustainable soil management of orchards can have positive effects on both soils and crop yields due to increases in microbial biomass, activity complexity. The aim this study was investigate medium‐term (12 yr) two different practices termed ‘sustainable’ ( ST ) ‘conventional’ CT composition metabolic diversity a rainfed mature olive orchard S outhern I taly. included no‐till, self‐seeding weeds (mainly graminaceous leguminosae), mulch derived from tree prunings, whilst managed by...
ABSTRACT Background Beneficial bacteria-plant interactions play an important role in agriculture, positively affecting plant status and improving product quality. Bacterial endophytes contribute to host protection survival. Aim This study characterised the bacterial communities present soil, leaf surface xylem sap of olive trees, investigated their response under a sustainable (Smng) or conventional (Cmng) management system grove located southern Italy. The aims are: (a) understand if soil...
Abstract This research aimed at investigating the isolation and identification of bacterial strains with biological nitrogen - fixing capability phosphate, potassium, zinc solubilization activities from a durum wheat field under two different tillage practices including 10 years conventional (CT) no-tillage (NT) practices. Attempts were also extended to estimate their relative abundances in soil as well develop accurate mathematical models determining effect temperatures, NaCl concentrations...
