Spatially variable organic-matter-driven clogging in a stormwater infiltration pond: Isotopic, microbiological and hydrogeological evidence.

Stormwater infiltration ponds (SIPs) are nature-based solutions which tend to decrease their infiltration capacity over time due to pore clogging. Organic matter (OM) is a well-known clogging driver, but how OM affects the physical and biochemical processes in a SIP remains largely unknown. An analysis encompassing soil organic carbon (SOC) stable isotopes, extracellular polymeric substances (EPS) of biofilms, DNA-based identification of microbiological communities and hydrogeological tests was carried out to elucidate the main clogging mechanisms in a large SIP in Italy.

GDP-mannose pyrophosphorylase is an efficient target in for citrus canker control.

Unlabelled: subsp. (Xcc) is a bacterium that causes citrus canker, an economically important disease that results in premature fruit drop and reduced yield of fresh fruit. In this study, we demonstrated the involvement of XanB, an enzyme with phosphomannose isomerase (PMI) and guanosine diphosphate-mannose pyrophosphorylase (GMP) activities, in Xcc pathogenicity.

Ecological indicators and biological resources for hydrocarbon rhizoremediation in a protected area.

Spillage from oil refineries, pipelines, and service stations consistently leads to soil, food and groundwater contamination. Bacterial-assisted phytoremediation is a non-invasive and sustainable solution to eliminate or decrease the concentration of xenobiotic contaminants in the environment. In the present study, a protected area interested by a fuel discharge was considered to assess a bioremediation intervention.

Selectivity and Activity of Benzene-1,2,4-triol and its Dimers as Antimicrobial Compounds Against Xanthomonas citri subsp. citri.

Citrus canker, caused by the bacterium Xanthomonas citri subsp. citri, is one of the main threats to citrus fruit production. Several phenolic compounds active against X.

Microbial communities in paddy soils: differences in abundance and functionality between rhizosphere and pore water, the influence of different soil organic carbon, sulfate fertilization and cultivation time, and contribution to arsenic mobility and speciation.

Abiotic factors and rhizosphere microbial populations influence arsenic accumulation in rice grains. Although mineral and organic surfaces are keystones in element cycling, localization of specific microbial reactions in the root/soil/pore water system is still unclear. Here, we tested if original unplanted soil, rhizosphere soil and pore water represented distinct ecological microniches for arsenic-, sulfur- and iron-cycling microorganisms and compared the influence of relevant factors such as soil type, sulfate fertilization and cultivation time.
