Summary Landfill sites are responsible for 6–12% of global methane emission. Methanotrophs play a very important role in decreasing landfill site emissions. We investigated the oxidation capacity and methanotroph diversity lysimeters simulating with different plant vegetations. Methane rates were 35 g m −2 day −1 or higher planted 18 less bare soil controls. Best oxidation, as displayed by gas depth profiles, was found under vegetation grass alfalfa. Methanotroph communities analysed at high...
Plants in combination with microorganisms can remediate soils, which are contaminated organic pollutants such as petroleum hydrocarbons. Inoculation of plants degrading bacteria is one approach to improve remediation processes, but often not successful due the competition resident microorganisms. It therefore high importance address persistence and colonization behavior inoculant strains. The objective this study was determine whether inoculation method (seed imbibement soil inoculation)...
Zero-valent iron nanoparticles (nZVI) treated by reduced sulfur compounds (i.e., sulfidated nZVI, S-nZVI) have attracted increased attention as promising materials for environmental remediation. While the preparation of S-nZVI and its reactions with various groundwater contaminants such trichloroethylene (TCE) were already a subject several studies, nanoparticle synthesis procedures investigated so far suited mainly laboratory-scale only limited possibility easy cost-effective large-scale...
To assess the degradation potential and plant colonization capacity of four alkane-degrading strains (ITSI10, ITRI15, ITRH76 BTRH79) in combination with birdsfoot trefoil Italian ryegrass to evaluate diversity indigenous soil bacteria rhizo- endosphere.Contaminated was prepared by spiking agricultural 10 g diesel fuel per kg soil. (Lolium multiflorum var. Taurus) (Lotus corniculatus Leo) were inoculated strains. Hydrocarbon (up 57%) observed all treatments vegetated unvegetated samples....
ABSTRACT A method was developed for the mRNA-based application of microbial diagnostic microarrays to detect active populations. DNA- and analyses environmental samples were compared confirmed via quantitative PCR. Results indicated that microarray may provide additional information on composition functioning communities.
A climate chamber experiment was conducted to assay the effect of low temperatures (chilling) on diversity bacteria colonizing endospheres two thermophilic sweet pepper (Capsicum anuum L.) cultivars, Milder Spiral and Ziegenhorn Bello. Structural analyzed by 16S rRNA-based terminal restriction fragment length polymorphism (T-RFLP) analysis generation rRNA gene libraries determine dominant community members in T-RFLP profiles. Cultivable lines Bello were identified analysis. profiles revealed...
Summary Nitrate is a dominant form of inorganic nitrogen (N) in soils and can be efficiently assimilated by bacteria, fungi plants. We studied here the transcriptome short‐term nitrate response using assimilating non‐assimilating strains model ascomycete Aspergillus nidulans . Among 72 genes positively responding to nitrate, only 18 carry binding sites for pathway‐specific activator NirA. Forty‐five were repressed metabolism. Because nirA ‐ are N‐starved at induction conditions, we also...
Soil salinity imposes an unprecedented risk to the soil fertility and availability of plant nutrients. The present proposal is designed address effect salt stress on photosynthetic apparatus maize including chlorophyll a fluorescence how silicon nutrition helps overcome this issue. In sand culture experiment, two cultivars were sown in small pots with levels (0 2 mM H2SiO3) 60 NaCl). Salinity reduced dry matter yield potassium (K) concentration both also induced inefficient working...
Petroleum contamination and its remediation via plant-based solutions have got increasing attention by environmental scientists engineers. In the current study, physiological growth responses of two diesel-tolerant plant species (tolerance limit: 1500-2000 mg/kg), Italian ryegrass (Lolium multiflorum) Birdsfoot trefoil (Lotus corniculatus), been investigated in vegetable oil- diesel oil-amended soils. A long-term (147-day) greenhouse pot experiment was conducted to differentiate main focus...
