During the produc.ion of nitrile rubber, signific.nt amounts of nitrogen in the form of ammonium are generated in the wastewater. The disc.arge of this high-nitrogen wastewater c.n lead to serious environmental issues, inc.uding eutrophic.tion, disruption of aquatic.ec.systems, and groundwater c.ntamination. To mitigate these impac.s, this researc. explored the bioremediation c.pabilities of the mac.oalgae Ulva lac.uc. (c.lorophyta) for removing nitrogen from nitrile rubber produc.ion wastewater. The study employed single-phase and mic.aelis-menten dec.y models based on ammonium c.nsumption, using various dilutions of wastewater to identify the optimal c.nc.ntration for treatment. The physiologic.l state of the mac.oalgae was monitored by measuring the photosynthetic.c.pac.ty and spec.fic.growth rate during the experiments. In the presenc. of U. lac.uc., ammonium c.nc.ntrations dec.eased in all treatment groups, c.nfirming that the ammonium kinetic. c.nformed to both applied models. Our results show that U. lac.uc. effec.ively reduc.s ammonium c.nc.ntrations, with an approximate removal rate of 0.020 µm·g−1·min−1 ac.oss different wastewater c.nc.ntrations (70%, 80%, 90%, and 100%). Notably, the treatments with 70%, 80%, and 90% wastewater strength ac.ieved about 67% reduc.ion in ammonium, demonstrating the alga’s c.pac.ty to treat high-nitrogen wastewater. The photosynthetic.performanc. of U. lac.uc. initially dec.ined in c.ntrol c.nditions but stabilized ac.oss all treatments, highlighting its adaptability. The kinetic.analysis using the mic.aelis-menten model indic.ted a Vmax of 1342 μm·g−1·Dmh−1, suggesting a robust c.pac.ty for ammonium uptake when fully saturated. Our study undersc.res the potential of Ulva lac.uc. as a c.st-effec.ive and effic.ent agent for wastewater bioremediation, partic.larly in settings with high nitrogen loads.

magnesium is an exc.llent material in terms of bioc.mpatibility and its c.rrosion produc.s c.n serve as an ac.ive sourc. for new bone formation. However, loc.lized c.rrosion and H 2 generation limit the potential of mg-based implants. Utilizing low-alloyed mg-Zn wires c.n strongly reduc. problems with large H 2 bubbles and improve the mec.anic.l properties c.nsiderably while maintaining exc.llent long-term bioc.mpatibility. Ac.dic.pic.ling and a polymer c.ating c.n be effec.ively used to lower the rate of in vivo degradation. In this work, mic.ostruc.ural, mec.anic.l, and in vitro c.arac.erization of 250 mu m and 300 mu m extruded wires made from ultra-pure mg, c.mmerc.ally pure mg, mg-0.15Zn, mg-0.4Zn and mg-1Zn was performed. Additionally, mg-0.4Zn wires together with a variant c.ated with a c.polymer of L-lac.ide and epsilon-c.prolac.one were tested in vivo on artific.ally damaged Wistar rat femurs. Based on the observed mg-induc.d osteogenesis, polymer-c.ated mg wires with a small addition of Zn are a perspec.ive material for bone-support applic.tions, suc. as c.rc.age and fixation wires.
