Nutrient availability is an important factor in crop production, and regular addition of chemical fertilizers the most common practice to improve yield agrosystems for intensive production. The use some groups microorganisms that have specific activity providing nutrients plants a good alternative, arbuscular mycorrhizal fungi (AMF) enhance plant nutrition by especially phosphorus (P), improving growth increasing Unfortunately, AMF as inoculant on large scale not yet widely used, because...
Abstract Background The emergence of multidrug-resistant bacteria is a world health problem. Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA) strains, one the most important human pathogens associated with hospital and community-acquired infections. aim this work was to evaluate antibacterial activity Pseudomonas aeruginosa -derived compound against MRSA strains. Methods Thirty clinical strains were isolated, three standard evaluated. extracellular compounds purified...
ABSTRACT The arbuscular mycorrhizal symbiosis, a key component of agroecosystems, was assayed as rhizosphere biosensor for evaluation the impact certain antifungal Pseudomonas inoculants used to control soil-borne plant pathogens. following three strains were tested: wild-type strain F113, which produces compound 2,4-diacetylphloroglucinol (DAPG); F113G22, DAPG-negative mutant F113; and F113(pCU203), DAPG overproducer. Wild-type F113 F113G22 stimulated both mycelial development from Glomus...
One of the most important postharvest plant pathogens that affect strawberries, grapes and tomatoes is Botrytis cinerea, known as gray mold. The fungus remains in latent form until spore germination conditions are good, making infection control difficult, causing great losses whole production chain. This study aimed to purify identify phenazine-1-carboxylic acid (PCA) produced by Pseudomonas aeruginosa LV strain determine its antifungal activity against B. cinerea. compounds were extracted...
Healthcare-associated infections are a major cause of morbidity-mortality among hospitalized patients. The aim this epidemiological study was to determine mortality and risks related death in adult patients with healthcare-associated admitted teaching hospital one year. Patient data were collected from infection medical reports. rate associated 38.4%, it classified as contributing factor deaths 87.1% cases. correlation between statistically significant clinical (41.3%) presenting...
Abstract Soybean and maize are some of the main drivers Brazilian agribusiness. However, biotic abiotic factors great concern, causing huge grain yield quality losses. Phosphorus (P) deficiency is important among because most soils have a highly P-fixing nature. Thus, large amounts phosphate fertilizers regularly applied to overcome rapid precipitation P. Searching for alternatives improve use P by crops essential reduce demand input. The multifunctional rhizobacteria can be considered one...
Twelve native woody species were studied to investigate the influences of soil fertility and root morphology on colonization by arbuscular mycorrhizal (AM) fungi during seedling establishment growth. Seedlings grown in soils low high natural fertility, uninoculated or inoculated with AM fungi, under greenhouse conditions. The plant responsiveness higher among early successional than late ones. Among species, both soils, provided significant increase total dry mass, growth rates shoot root,...
Citrus canker is a lot destructive disease of citrus species. The challenge to find new compounds that show strong antibiotic activity, low toxicity plants and the environment. objectives present study are (1) produce, purify evaluate activity secondary metabolites produced by induction P. aeruginosa LV strain in vitro against Xanthomonas citri subsp. (strain 306), (2) potential for semi-purified on foliar application control under greenhouse conditions, (3) identify orange leaf mesophyll...
Schizolobium parahyba var. amazonicum (Huber ex Ducke) occurs naturally in the Brazilian Amazon. Currently, it is being planted extensively because of its fast growth and excellent use forestry. Consequently, there great interest new strategies to increase wood production. The interaction between soil microorganisms plants, specifically roots, provides essential nutrients for plant growth. These interactions can have growth-promoting effects. In this way, study assessed effect inoculation...
In this work, we evaluated the antibiotic activity of metabolites produced by Pseudomonas sp. LV strain and their effects on cell morphology Xanthomonas citri pv. 306 (Xcc 306), which causes citrus canker lesions. The was cultivated, centrifuged, a cell-free supernatant treated with dichloromethane then concentrated, frozen in liquid nitrogen lyophilized. phase (DP) fractionated vacuum chromatography (VLC) using six organic solvents crescent polarity. DP all fractions from VLC were tested...
Phytopathogenic microorganisms are the main cause of plant diseases, generating significant economic losses for agricultural and food supply chain. Cherry tomatoes (Solanum lycopersicum var. cerasiforme) very perishable plants highly demanding in use pesticides; therefore, alternative solutions such as biosurfactants have aroused a potent substituent. The objective present study was to investigate antimicrobial activity sophorolipids against phytopathogens Botrytis cinerea, Sclerotium...
Some diazotrophic bacteria can fix nitrogen biologically in gramineous host plants. Generally, plants are also associated with mycorrhizal fungi, that improve mainly plant P uptake. Among the factors affecting plant-microbe interactions, genotype plays an important role. This study evaluates effect of and arbuscular fungus (AMF), on five genotypes maize (Zea mays L.), relation to biomass, shoot N concentrations, fine root morphological traits. The experimental design was entirely randomized...
