A greenhouse pot experiment was carried out to evaluate the efficiency of arsenic phytoextraction by fern Pteris vittata growing in arsenic-contaminated soil, with or without addition selected rhizobacteria isolated from polluted site. The bacterial strains were for resistance, ability reduce arsenate arsenite, and promote plant growth. P. plants cultivated 4 months a contaminated substrate consisting arsenopyrite cinders mature compost. Four different experimental conditions tested: (i)...
Pseudomonas sp. MP12 was isolated from a soil sample collected in typical warm-temperate deciduous forest near Brescia, Northern Italy. Phylogenetic analysis identified the species as protegens. We evidenced this strain presence of genes phlD, pltB and prnC responsible for synthesis antifungal compounds 2,4-diacetylphloroglucinol (2,4-DAPG), pyoluteorin pyrrolnitrin, respectively. P. protegens also shown to produce siderophores ammonia, yielded positive results with indole-3-acetic acid...
An extensive taxonomic analysis of the bacterial strain Burkholderia sp. DBT1, previously isolated from an oil refinery wastewater drainage, is discussed here. This capable transforming dibenzothiophene through 'destructive' oxidative pathway referred to as Kodama pathway. DBT1 has also been proved use fluorene, naphthalene and phenanthrene carbon energy sources, although growth on first two compounds requires a preinduction step. evidence suggests that exerts versatile metabolism towards...
Biosurfactants are surface-active compounds with environmental and industrial applications. These molecules show higher biocompatibility, stability efficiency compared to synthetic surfactants. On the other hand, biosurfactants not cost-competitive their chemical counterparts. Cost effective technology such as use of low-cost substrates is a promising approach aimed at reducing production cost. This study evaluate biosurfactant activity by novel strain Rhodococcus sp. SP1d using different...
Lignocellulose biomasses (LCB), including spent mushroom substrate (SMS), pose environmental challenges if not properly managed. At the same time, these renewable resources hold immense potential for biofuel and chemicals production. With market growth expected to amplify SMS quantities, repurposing or disposal strategies are critical. This study explores use of cultivating microbial communities produce carbohydrate-active enzymes (CAZymes). Addressing a research gap in using anaerobic...
Polyhydroxyalkanoates (PHAs) are versatile biodegradable polymers produced by bacteria and suitable for many downstream applications. They can be inexpensively from mixed microbial cultures under feast famine conditions in the presence of biobased volatile fatty acids (VFAs). Here, we investigated effect changing sludge retention time (SRT) addition fermented cellulosic primary (CPS) as a carbon source on selection PHA-storing biomass when applying strategy aerobic anoxic conditions,...
The production of medium chain fatty acids (MCFAs) through reverse β-oxidation was investigated both on synthetic and real substrates. From preliminary batch tests emerged that caproic acid maximized under an acetate/ethanol molar ratio 5:1 at neutral pH. This then adopted in different semi-continuous operating with amounts the two reactants. It MCFAs yield reached maximum level 6.7% when total substrate amount around 40-45 mmol/d, while process inhibited for values higher than 400 mmol/d....
An evaluation was conducted of the colonization Pseudomonas protegens MP12, a plant-growth promoting and antagonistic strain, inoculated in vine plants during standard process grapevine nursery propagation. Three vivo inoculation protocols (endophytic, rhizospheric, epiphytic) were implemented monitored by means both culture-dependent independent techniques. Endophytic treatment resulted bacterium inside cuttings, which spread to young leaves forcing period. Microscopy analysis performed on...
Thauera is one of the main genera involved in polyhydroxyalkanoate (PHA) production microbial mixed cultures (MMCs) from volatile fatty acids (VFAs). However, no strains PHA accumulation have been obtained pure culture so far. This study first report isolation and characterization a sp. strain, namely Sel9, sequencing batch reactor (S-SBR) set up for selection storing biomass. The 16S rRNA gene evidenced high sequence similarity with T. butanivorans species. Genome identified all genes...
The microbial communities of the rhizospheres vineyards have been subject to a considerable body research, but it is still unclear how applied soil cultivation methods are able change structure, composition, and level diversity their communities. Rhizosphere samples were collected from three neighbouring with same time planting material (rootstock: Teleki 5C; Vitis vinifera: Müller Thurgau). Our objective was examine occurring in bacterial community structures that differ only tillage...
Abstract Aims This study investigates the traits of three plant growth-promoting (PGP) and antagonistic bacteria, Pseudomonas protegens MP12, Bacillus sp. 3R4, T22, to assess their potential application as biocontrol agents by using ecofriendly low-cost substrate Corn Steep Liquor (CSL) medium. Analyses antagonism through volatile organic compounds (VOCs) production, biofilm formation, growth performance were carried out. Methods results Dual assay showed that all strains displayed...
In this study, the production of polyhydroxyalkanoated PHA-rich microbial biomass as a novel feed additive in aquaculture was investigated at lab-scale. Bio-based volatile fatty acids (VFAs), obtained from acidogenic fermentation agricultural residues existing anaerobic digestion plants, were used carbon and energy to cultivate biomass. The experimental activities carried out using Thauera sp. Sel9 pure strain, which grown continuous stirred-tank reactor (CSTR) operated three different...
This study evaluates the capacity of commercial formulations synthetic fungicides to inhibit grapevine bacterial growth when sprayed on vineyards control diseases, such as downy mildew, powdery mildew and secondary rots. Fungicide sensitivity plate assays were carried out bacteria isolated from that also identified characterized for their plant growth-promoting (PGP) traits antifungal activity. The high taxonomic variability screened with different chemical classes is one new finding this...
Abstract Burkholderia fungorum DBT1, first isolated from settling particulate matter of an oil refinery wastewater, is a bacterial strain which has been shown capable utilizing several polycyclic aromatic hydrocarbons (PAHs) including dibenzothiophene (DBT). In particular, this microbe able to efficiently degrade DBT through the Kodama pathway. Previous investigations have lead identification six genes, on total eight, required for degradation. present study, combined...
