Active biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) melt mixed nanocomposites and bilayer structures containing cooper oxide (CuO) nanoparticles were developed and characterized. The bilayer structures consisted of a bottom layer of compression molded PHBV3 (3% mol valerate) coated with an active electrospun fibers mat made with microbial mixed culture derived PHBV18 (18 % valerate) and CuO nanoparticles. The results showed that the oxygen barrier properties were slightly enhanced by the addition of 0.05% CuO nanoparticles to nanocomposite films but a negligible effect was registered for the bilayer structures. Neither the water vapor permeability nor the mechanical properties were modified by the addition of CuO.Interestingly, by incorporating highly dispersed and distributed CuO nanoparticles in a coating by electrospinning, a lower metal oxide loading was required to exhibit significant bactericidal and virucidal performance against the food-borne pathogens Salmonella enterica, Listeria monocytogenes and Murine norovirus. The biodisintegration tests of the samples under composting conditions showed that even the 0.05% CuO coated structures biodegraded within 35 days.

Abstract. Although green synthesis of nanoparticles (NPs) has replaced conventio na l physicochemical methods owing to eco-friendly and cost effective nature but molecular mechanism is not known completely. Elucidation of the mechanism is needed to enhance the production of control size synthesis and for understanding the biomineralization process. Here we report the facile, extracellular biosynthesis of silver nanoparticles (AgNPs) by Pseudomonas aeruginosa JP1 through nitrate reductase mediated mechanism. AgNO3 was reduced to AgNPs by cell filtrate exposure. UV-visible spectrum of the reaction mixture depicted reduction of ionic silver (Ag + ) to atomic silver (Ag 0 ) by a progressive upsurge in surface plasmon resonance (SPR) band range 435-450 nm. X-ray diffraction analysis showed the 2θ values at 38.08°, 44.52°, 64.42° and 77.44° confirming the crystalline nature and mean diameter [6.5-27.88nm (Ave = 13.44 nm)] of AgNPs. Transmission electron microscopy analysis demonstrated the spherical AgNPs with size range 5-45 nm. Stabilizing proteins and rhamnolipids were recognized by Fourier transform infrared spectroscopy. Nitrate reductase was purified and characterized (molecular weight 65 kDa and specific activity = 5.6 U/mg). To probe the plausible mechanism purified enzyme was retreated with AgNO3. Characteristic SPR bands range (435-450 nm) and Particle-induced x-ray emission results also confirmed the synthesis of AgNPs (59679.5 ppm) in solution. These results demonstrated that, nitrate reductase as a principal reducing agent in the mechanistic pathway of AgNPs synthesis, which leads to the understanding of metal transformation and biomineralization processes for controlling the biogeochemical cycles of silver and other heavy metals.

“…However, it was still lower than Cu(II) ions adsorption capacity by activated carbon prepared from watermelon (31.02 mg/g) [14], Tunisian date stones (31.25 mg/g) [23] and hazelnut shell (58.27 mg/g) [33]. For further research, bamboo-based activated carbon [49] will be considered to compate for adsorption of Cu(II).…”

Adsorption of Cu(II) ions from aqueous solution using activated carbon prepared from Limonia acidissima fruit shell (LAFS-AC) was conducted in batch mode experiments at pH 5 (±0.15), 100 rpm and 1 atm. The effects of contact time, initial Cu(II) ions concentration, KOH concentration, and adsorption temperature on Cu(II) ions adsorption capacity were investigated. Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy analyses were performed to investigate the active site and surface morphology of the LAFS-AC, respectively. The Cu(II) ions adsorption was fitted very well (R 2 = 0.94 on average) to the pseudo second-order adsorption kinetic with the adsorption capacity and rate being 25.58 mg/g and 0.07 g/mg.min, respectively at 27 o C by the LAFS AC activated using 0. Abstract Adsorpsi Ion Cu(Ii) di dalam Larutan Berair menggunakan Karbon Aktif Berbasis Kulit BuahLimonia acidissima: Studi Kinetika dan Isotermal. Adsorpsi ion Cu(II) dari larutan berair menggunakan karbon aktif yang dibuat dari kulit buah Limonia acidissima (LAFS-AC) dilakukan pada percobaan dengan sistem batch pada pH 5 (± 0,15), 100 rpm dan 1 atm. Efek waktu kontak, konsentrasi awal ion Cu(II), konsentrasi KOH, dan suhu adsorpsi pada adsorpsi ion Cu (II) diselidiki. Analisis spektroskopi FTIR dan SEM dilakukan untuk menyelidiki morfologi bagian aktif dan permukaan LAFS-AC. Adsorpsi ion Cu(II) memiliki kemiripan (R2 rata-rata = 0,94) terhadap kinetika adsorpsi pseudo orde kedua dengan kapasitas adsorpsi dan laju masing-masing 25,58 mg/g dan 0,07 g/mg.min pada suhu 27 o C pada LAFS-AC aktif menggunakan 0,5 M KOH. Pada suhu 60 o C, nilainya menjadi 26,88 mg/g dan 0,15 g/mg.min. Adsorbsi ion Cu(II) mengikuti model adsorpsi isotherm Langmuir (LAIM) (R2 = 0,98 rata-rata). Kapasitas adsorpsi LAIM dan konstanta masing-masing bernilai 26,67 mg/g dan 0,03 L/g pada suhu 27 o C. Pada suhu 60 o C, nilainya meningkat secara dramatis menjadi 0,09 L/g. Kondisi adsorpsi optimal yang diperoleh adalah 0,5 M KOH pada LAFS-AC aktif, konsentrasi awal Cu(II) 509,81 mg/L dan waktu kontak 120 menit pada suhu 60 o C dengan kapasitas adsorpsi ion Cu(II) sebesar 26,95 mg/g.
