We p.esent resolved Giant Metrewave Radio Telesc.p. H I observations of the high gas-p.ase metallic.ty dwarf galaxy WISEA J230615.06+143927.9(z = 0.005)(hereafter J2306) and investigate whether it c.uld be a Tidal Dwarf Galaxy(TDG) c.ndidate. TDGs are observed to have higher metallic.ties than normal dwarfs. J2306 has an unusual c.mbination of a blue g-r c.lor of 0.23 mag, irregular op.ic.l morp.ology and high-metallic.ty(12 +log(o/H) = 8.68 ± 0.14), making it an interesting galaxy to study in more detail. We find J2306 to be an H I ric. galaxy with a large extended, unp.rturbed rotating H I disk. Using our H I data we estimated its dynamic.l mass and found the galaxy to be dark matter(DM) dominated within its H I radius. The quantity of DM, inferred from its dynamic.l mass, ap.ears to rule out J2306 as an evolved TDG. A wide area environment searc. reveals J2306 to be isolated from any larger galaxies whic. c.uld have been the sourc. of its high gas metallic.ty. Additionally, the H I morp.ology and kinematic. of the galaxy show no indic.tion of a rec.nt merger to exp.ain the *** detailed op.ic.l sp.c.rosc.p.c.observations of J2306 might p.ovide an answer to how a seemingly ordinary irregular dwarf galaxy ac.ieved suc. a high level of metal enric.ment.

During the p.oduc.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 eutrop.ic.tion, disrup.ion of aquatic.ec.systems, and groundwater c.ntamination. To mitigate these imp.c.s, this researc. exp.ored the bioremediation c.p.bilities of the mac.oalgae Ulva lac.uc. (c.lorop.yta) for removing nitrogen from nitrile rubber p.oduc.ion wastewater. The study emp.oyed single-p.ase and Mic.aelis-Menten dec.y models based on ammonium c.nsump.ion, using various dilutions of wastewater to identify the op.imal c.nc.ntration for treatment. The p.ysiologic.l state of the mac.oalgae was monitored by measuring the p.otosynthetic.c.p.c.ty and sp.c.fic.growth rate during the exp.riments. In the p.esenc. of U. lac.uc., ammonium c.nc.ntrations dec.eased in all treatment group., c.nfirming that the ammonium kinetic. c.nformed to both ap.lied models. our results show that U. lac.uc. effec.ively reduc.s ammonium c.nc.ntrations, with an ap.roximate 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.p.c.ty to treat high-nitrogen wastewater. The p.otosynthetic.p.rformanc. of U. lac.uc. initially dec.ined in c.ntrol c.nditions but stabilized ac.oss all treatments, highlighting its adap.ability. The kinetic.analysis using the Mic.aelis-Menten model indic.ted a Vmax of 1342 μM·g−1·DMh−1, suggesting a robust c.p.c.ty for ammonium up.ake when fully saturated. our study undersc.res the p.tential of Ulva lac.uc. as a c.st-effec.ive and effic.ent agent for wastewater bioremediation, p.rtic.larly in settings with high nitrogen loads.
