Interfacing intact and metabolically active photosynthetic bacteria with abiotic electrodes requires both establishing extracellular electron transfer immobilizing the biocatalyst on electrode surfaces. Artificial approaches for photoinduced harvesting through redox polymers reported in literature require separate synthesis of artificial polymeric matrices their subsequent combination bacterial cells, making development biophotoanodes complex less sustainable. Herein, we report a one-pot...
Abstract Living photovoltaics are microbial electrochemical devices that use whole cell–electrode interactions to convert solar energy electricity. The bottleneck in these technologies is the limited electron transfer between microbe and electrode surface. This study focuses on enhancing this by engineering a polydopamine (PDA) coating outer membrane of photosynthetic Synechocystis sp. PCC6803. provides conductive nanoparticle shell increase adhesion improve charge extraction. A combination...
Xylella fastidiosa is a bacterial pathogen affecting many plant species worldwide. Recently, the subspecies pauca (Xfp) has been reported as causal agent of devastating disease on olive trees in Salento area (Apulia region, southeastern Italy), where centenarian and millenarian plants constitute great agronomic, economic, landscape trait, well an important cultural heritage. It is, therefore, to develop diagnostic tools able detect early, even when infected are still asymptomatic, reduce...
Abstract Photosynthetic organisms such as diatoms microalgae provide innovative routes to eco‐friendly technologies for environmental pollution bioremediation. Living are capable incorporate in vivo a wide variety of chemical species dispersed seawater, thus being promising candidates removal toxic contaminants. However, their exploitation requires immobilization methods that allow confine during water treatment. Here we demonstrate biofilm Phaeodactylum tricornutum diatom cells grown on the...
Polydopamine (PDA) is a synthetic eumelanin polymer mimicking the biopolymer secreted by mussels to attach surfaces with high binding strength. It exhibits unique adhesive properties and has recently attracted considerable interest as multifunctional thin film coating. In this study, we demonstrate that PDA coating on silica- polymer-based materials improves entrapment retention of uremic toxins produced in specific diseases. The low-cost natural nanotextured fossil diatomaceous earth (DE),...
Grapevine fanleaf virus (GFLV) (genus Nepovirus, family Secoviridae) causes degeneration, one of the most damaging viral diseases grapevines. Despite substantial advances at deciphering GFLV-host interactions, how this overcomes host antiviral pathways RNA silencing is poorly understood. In study, we identified suppressors (VSRs) encoded by GFLV, using fluorescence assays, and tested their capacity modifying gene expression in transgenic Nicotiana benthamiana expressing enhanced green...
RNA interference (RNAi) is a sequence identity-dependent degradation mechanism conserved in eukaryotic organisms. One of the roles RNAi as defense system against viral infections, which has been demonstrated filamentous fungi but not oomycetes. We investigated virus-RNAi interplay oomycete Phytophthora infestans using crucifer-infecting strain plant virus tobacco mosaic (TMVcr) and its derivative TMVcr-Δ122 that mutated p122 replicase subunit thus inhibited suppression activity. In this...
The development of bioelectrochemical systems requires careful selection both their biotic and abiotic components to obtain sustainable devices. Herein, we report a biophotoelectrode obtained with polyhydroxybutyrate (PHB), biopolymer, which purple non-sulphur bacteria produce as an energy stock under specific environmental conditions. electrode was by casting mixture composed PHB carbon fibers in 3:2 mass ratio. Following, the composite material modified polydopamine thermally treated...
Olive anthracnose, a fungal disease caused by species of the genus Colletotrichum, is responsible for severe yield losses and poor oil quality. Typical symptoms appear in autumn or early winter, when drupes begin to ripen. Under favorable conditions, on branches leaves can also occur, leading chlorosis, defoliation, death woody organs. Symptomless infection flowers blights have been reported. Latent fruit infections could play an important role as inoculum source autumn-winter epidemics....
