Abstract Due to anthropogenic activities, heavy metal (HM) pollution in soils has increased, resulting severe ecological problems and posing a constant threat human health. Among various remediation methods, bacterial is relatively clean, efficient, minimally negative approach. However, agents face multiple environmental stresses, making them challenging achieve long-lasting stable restoration effects. To address this issue, supportive organic substances such as biochar can be added the soil...
Heterotrophic nitrifying bacteria are found to be promising candidates for implementation in wastewater treatment systems due their tolerance extreme environments. A novel acid-resistant bacterium, Pseudomonas citronellolis YN-21, was isolated and reported have exceptional heterotrophic nitrification capabilities acidic condition. At pH 5, the highest NH
The roles of napA and narG genes encoding nitrate reductase in the nitrogen cycle remain unclear. In this study, we constructed napA- narG-knockout mutants complementary strains compared their transformation characteristics with those wild-type strain Pseudomonas putida Y-9, which can simultaneously perform assimilation (ANRA), dissimilatory reduction to ammonium (DNRA), denitrification under aerobic conditions. deletion did not affect removal (NO3-) by P. efficiency mutant (88.59%) was...
Dissimilatory nitrate reduction to ammonium (DNRA) has an important role in soil nitrogen retention and is considered be constrained anaerobic conditions. However, a recent study found that Pseudomonas putida Y-9 capable of DNRA under aerobic In this study, four species spp. were produce during the nitrite process conditions, similar strain. The detectable culture supernatant for each strains originated intracellularly. A subsequent 15N isotope experiment showed these able transform 15NO2-...
The process of diffusion bonding in air was successfully used to join 5A90 Al–Mg–Li alloy, which can greatly reduce the welding cycle and equipment requirements. Before bonding, Cu nano-coating prepared on surface alloy by ultrasonic electrodeposition as interlayer hinder formation oxide film increase atomic diffusion. effects coating thickness, temperature types microstructure performance joints were investigated. When 530 °C thickness 5.12 μm, optimal shear strength joint with 1 μm-thick...
Phytophthora nicotianae is a fungal soil-borne pathogen that damages various plant species. Mancozeb and Zineb, fungicides containing manganese (Mn) zinc (Zn) as the main components, are widely used to control diseases caused by Phytophthora. However, inhibition mechanism still unclear. The purpose of this study was examine effects Mn Zn on P. determine possible inhibitory mechanisms sporangiogenesis nicotianae.The mycelial growth, sporangium generation, zoosporogenesis zoospore germination...
In this paper, the differences in mechanical properties and high temperature (HT) deformation behavior between TiBw/Ti65 TiBw/TA15 composites with network structure were studied. The alloy element distribution microstructure of characterized by electron probe micro analyzer transmission microscopy. evolution during HT was analyzed back scatter diffraction. two tested at room 600–750 °C. Arrhenius artificial neural models developed to predict peak stress flow stress, respectively. results...
