A prerequisite to exploiting soil microbes for sustainable crop production is the identification of plant genes shaping microbiota composition in rhizosphere, interface between roots and soil. Here, we use metagenomics information as an external quantitative phenotype map host genetic determinants rhizosphere wild domesticated genotypes barley, fourth most cultivated cereal globally. We identify a small number loci with major effect on communities. One those, designated QRMC-3HS, emerges...
A bacteriocin-producing Bacillus cereus strain was isolated. The bacteriocin, here called cerein, shown to be active specifically against other B. strains and inactive all bacterial species tested. Cerein detected in the culture supernatants of stationary-phase cells, its appearance inhibited by induction sporulation. activity cerein insensitive organic solvents nonproteolytic enzymes, partially stable heat, over a wide range pH values. Direct detection antimicrobial on sodium dodecyl...
Human beta-defensins (hBDs) are antimicrobial peptides of human innate immunity. The antibacterial activities hBDs 1, 2, and 4 but not the activity hBD3 impaired by high salt levels. We have designed synthesized seven novel hBD analogs, constituted different domains hBD1 (which is constitutively expressed in humans) induced microorganisms inflammatory factors humans), that would maintain potentially increase wild-type be resistant. compared antibacterial, antiviral, chemotactic analogs with...
Phragmites australis and Typha latifolia are two macrophytes commonly present in natural artificial wetlands. Roots of these plants engage interactions with a broad range microorganisms, collectively referred to as the microbiota. The microbiota contributes process phytodepuration, whereby pollutants removed from contaminated water bodies through plants. outermost layer root corpus, rhizoplane, is hot-spot for where microorganisms establish specialized aggregates designated biofilm. Earlier...
Endospores of Bacillus subtilis are encased in a protein shell, known as the spore coat, composed lamella-like inner layer and an electron-dense outer layer. We report identification characterization gene, herein called cotH, located at 300 degrees on B. genetic map between two divergent cot genes, cotB cotG. The cotH open reading frame extended for 1,086 bp corresponded to polypeptide 42.8 kDa. Spores null mutant were normally heat, lysozyme, chloroform resistant but impaired germination....
BACKGROUND: Applications of bacteriocins as food preservatives have been so far limited, principally because their low antimicrobial activity in foods. Nisin is the only bacteriocin significant use, but applications are restricted its very at neutral or alkaline pH. Thus isolation new active foods desirable. RESULTS: We isolated a Bacillus licheniformis thermophilic strain producing with some novel features, named here bacillocin 490. This was inactivated by pronase E and proteinase K...
This research aimed to characterise hydrocarbonoclastic bacteria isolated from naturally hydrocarbon-contaminated springs and the surrounding soils in Agri Valley (Southern Italy) assess effectiveness of bioaugmentation using a four-strain microbial consortium for removing hydrocarbons artificially diesel-contaminated lake waters mesocosm experiments. Four novel bacterial strains were selected experimentation: Gordonia amicalis S2S5, Rhodococcus erythropolis S2W2, Acinetobacter tibetensis...
ABSTRACT Limestone aquifers provide the main drinking water resources of southern Italy. The groundwater is often contaminated by fecal bacteria because interaction between rocks having high permeability and microbial pollutants introduced into environment grazing and/or manure spreading. contamination springwater in picnic areas located mountains can cause gastrointestinal illness. This study was carried out order to analyze Enterococcus faecalis soil a limestone aquifer verify influence...
Terra Nova, 00, 1–6, 2010 Abstract Epikarst formation in the southern Apennines (Italy) was hypothesized to be significantly influenced by diffuse rainwater infiltration through soil of pyroclastic origin. Multidisciplinary investigations were carried out at an experimental field site test this hypothesis. At site, other factors influencing epikarst can assumed invariant. A direct relationship observed between thickness and thickness. This supports hypothesis that plays a significant role...
We report Western blot data showing that the 42.8-kDa product of previously characterized cotH locus (8) is a structural component Bacillus subtilis spore coat. show assembly CotH requires both CotE and GerE. In agreement with these observations, ultrastructural analysis purified spores suggests needed for proper formation inner outer layers
Strong catalase activity was secreted by Bacillus subtilis cells during stationary growth phase in rich medium but not sporulation-inducing medium. N-terminal sequencing indicated that the due to vegetative KatA, previously considered an endocellular enzyme. Extracellular protected B. from oxidative assault.
A well-established rat model of diet-induced metabolic syndrome was used to evaluate the effects oral administration spores or cells HU16, a carotenoid-producing strain Bacillus indicus . Symptoms were induced in 90-days old, male Sprague-Dawley rats maintained for eight weeks on high-fat diet, as previously reported. Parallel groups animals under same diet regimen also received daily dose 1×10 10 B. HU16. Cells HU16 able reduce symptoms syndrome, plasma markers inflammation and oxidative...
The chemical composition of essential oils (EOs) from dried and fresh flowers Lavandula angustifolia L. (lavender), named LA 2019 2020, respectively, grown in central Italy was analyzed compared by GC GC-MS. For both samples, 61 compounds were identified, corresponding to 97.9% 98.1% the total oils. Explorative data analysis, performed compare statistical resulted a high level global similarity (around 93%). compositions samples characterized 10 major compounds, with predominance Linalool...
Heat and cold shock response are normally considered as independent phenomena. A small amount of evidence suggests instead that interactions may exist between them in two Lactococcus strains.We show the occurrence molecular relationships mechanisms heat adaptations Streptococcus thermophilus, a lactic acid bacterium widely used dairy fermentation, where it undergoes both types stress. We observed cryotolerance is increased when cells pre-incubated at high temperature. In addition, production...
The aim of this study was to experimentally verify the significance microbial transport through low-permeability fault zones in a compartmentalised carbonate aquifer system Southern Italy.
