Abstract In this study, we identified a suitable precursor and good cellular compartmentalization for enhancing bioactive metabolites to produce biosynthetic zinc oxide nanoparticles (ZnO NPs). An effective medium cultivating endophytic Streptomyces albus strain E56 was selected using several optimized approaches in order maximize the yield of ZnO NPs. The highest NPs (4.63 g/L) obtained when pipetting mixed cell-free fractions with 100 mM sulfate as precursor. generation quickly verified colored solution (white color) UV–Visible spectroscopy (maximum peak, at 320 nm). On small scale, Taguchi method applied improve culture culturing E56. As result, its cell-dry weight 3.85 times that control condition. And then biosynthesis (7.59 increased by 1.6 times. Furthermore, Plackett–Burman design utilized biogenesis pathway, (18.76 4.3 To find best growth production line, used batch fed fermentation modes gradually scale up biomass output.

New advances in nanotechnology are driving a wave of technology revolution impacting broad range areas agricultural production. The current work reviews nanopesticides, nano-fabricated fertilizers, and nano activity-based growth promoters reported the last several years, focusing on mechanisms revealed for preparation functioning. It appears to us that with many fundamental concepts have been demonstrated over two decades, new this area continue expand mainly three directions, i.e., efficiency improvement, material sustainability environment-specific stimulation functionalities. is also evident environmental health concerns associated agrochemicals primary motivation focus most recent work. Challenges perspectives future development discussed.

Nanopesticides are considered to be a promising alternative strategy for enhancing bioactivity and delaying the development of pathogen resistance pesticides. Here, new type nanosilica fungicide was proposed demonstrated control late blight by inducing intracellular peroxidation damage Phytophthora infestans, associated with potato blight. Results indicated that structural features different silica nanoparticles were largely responsible their antimicrobial activities. Mesoporous (MSNs) exhibited highest activity 98.02% inhibition rate P. causing oxidative stress responses cell structure in infestans. For first time, MSNs found selectively induce spontaneous excess production reactive oxygen species pathogenic cells, including hydroxyl radicals (•OH), superoxide (•O2–), singlet (1O2), leading The effectiveness further tested pot experiments as well leaf tuber infection, successful achieved high plant compatibility safety. This work provides insights into mechanism highlights use controlling green highly efficient nanofungicides.

The ability of modern agriculture to meet future food demand imposed by accelerating growth the world's population is a major challenge, and fertilizers play key role replacing nutrients in agricultural soil. Given need for fertilizers, their cost nonrenewable resources energy, consequences greenhouse gas emissions required make them, people have begun explore ways fertilizer manufacturing use more sustainable. Using data from CAS Content Collection, this review examines analyzes academic patent literature on sustainable 2001 2021. breakdown journal publication over time topic, country or region publications, substances included published research, among other things allow us understand general progress field as well classes materials concepts driving innovation. We hope that bibliometric analysis literary will assist researchers relevant industries discover implement supplement conventional nutrient sources while improving efficiency sustainability waste management ammonia production.
