Xanthomonas citri subsp. (Xcc) causes citrus canker, affecting sweet orange-producing areas around the world. The current chemical treatment available for this disease is based on cupric compounds. For reason, objective of study was to design antibacterial agents. In order do this, we analyzed anti-Xcc activity 36 alkyl dihydroxybenzoates and found 14 active Among them, three esters with lowest minimum inhibitory concentration values were selected; compounds 4 (52 μM), 16 (80 μM) 28 (88 μM)....
This study investigates the impact of long-term heavy metal contamination on culturable, heterotrophic, functional and genetic diversity rhizobacterial communities perennial grasses in water meadow soil. The culturable heterotrophic was investigated by colony appearance solid LB medium. Genetic measured as bands denaturing gradient gel electrophoresis (DGGE) obtained directly from rhizosphere soil rhizoplane DNA extracts, corresponding communities. In two rhizospheric fractions DGGE profiles...
Aims: To analyse the arsenic‐resistant bacterial communities of two agricultural soils Bangladesh, to isolate bacteria, study their potential role in arsenic transformation and investigate genetic determinants for resistance among isolates. Methods Results: Enrichment cultures were performed a minimal medium presence As(III) As(V) resistant bacteria. Twenty‐one bacteria belonging different genera Gram‐positive Gram‐negative isolated. The isolates, with exception Oceanimonas doudoroffii Dhal...
Nitrospirae spp. distantly related to thermophilic, sulfate-reducing Thermodesulfovibrio species are regularly observed in environmental surveys of anoxic marine and freshwater habitats. Here we present a metaproteogenomic analysis bacterium Nbg-4 as representative this clade. Its genome was assembled from replicated metagenomes rice paddy soil that used grow the presence absence gypsum (CaSO4·2H2O). encoded full pathway dissimilatory sulfate reduction showed expression gypsum-amended bulk...
This review provides insights on (1) the chemistry of arsenic (As) in soil environment and factors (e.g., pH, presence, nature, concentration competing inorganic organic ligands), which regulate sorption/desorption arsenate arsenite (the most abundant As species soils waters) on/from components; (2) chemical fractionation speciation to identify that are more mobile phytoavailable; finally (3) uptake by selected edible plants production techniques able reduce its translocation plant tissues.
Arsenic contamination of groundwater aquifers is an issue global concern. Among the affected sites, in several Italian arsenic levels above WHO limits for drinking water are present, with consequent issues public In this study, first time, role microbial communities metalloid cycling samples from Northern Italy lying on Pleistocene sediments deriving Alps mountains has been investigated combining environmental genomics and cultivation approaches. 16S rRNA gene libraries revealed a high...
Curcumin is the main constituent of turmeric, a seasoning popularized around world with Indian cuisine. Among benefits attributed to curcumin are anti-inflammatory, antimicrobial, antitumoral, and chemopreventive effects. Besides, inhibits growth gram-positive bacterium Bacillus subtilis. The anti-B. subtilis action happens by interference division protein FtsZ, an ancestral tubulin widespread in Bacteria. FtsZ forms protofilaments GTP-dependent manner, concomitant recruitment essential...
Rhodococcus sp. 1BN was isolated from a contaminated site and showed various biodegradative capabilities. Besides naphthalene, strain degraded medium‐ (C 6 ) long‐chain alkanes 16 –C 28 ), benzene toluene, alone or when the hydrocarbons were mixed in equal proportions. The nucleotide sequence of an alk polymerase chain reaction (PCR) fragment revealed 59% homology to Pseudomonas oleovorans alkB gene. nar fragments highly homologous genes coding for large small subunits cis ‐naphthalene...
Chlorinated ethene contamination is a worldwide relevant health issue. In anaerobic aquifers, highly chlorinated ethenes are transformed by microbially-mediated organohalide respiration metabolism. For this reason, in the last few years, bioremediation interventions have been developed and employed situ for aquifer decontamination. Biostimulation has demonstrated to be efficient enhancing activity. The use of agrifood wastes that replace engineered substrates as biostimulants permits low...
Abiotic factors and rhizosphere microbial populations influence arsenic accumulation in rice grains. Although mineral organic surfaces are keystones element cycling, localization of specific reactions the root/soil/pore water system is still unclear. Here, we tested if original unplanted soil, soil pore represented distinct ecological microniches for arsenic-, sulfur- iron-cycling microorganisms compared relevant such as type, sulfate fertilization cultivation time. In open-air-mesocosms...
