The complexes of Cu and Mn metals with carboxylates (pivalic acid and benzoic acid) and imidazole were prepared and characterized. The synthesized complexes were screened for antimicrobial activity and cytotoxicity. The FTIR technique was used for characterization. The antibacterial assay revealed that the ligand and complexes are active against Escherichia coli, Staphylococcus aureus and Pasteurella multocida bacterial strains. The haemolytic assay revealed that [Cu(imi)(N₃)] and [MnIII(piv)(imi)(N₃)] were nontoxic, whereas [Cu(piv)(imi)] and [MnIII(Benz)(imi)(OCH₃)] showed moderate toxicity, and [Mn(Him)(N₃)₂] was highly toxic against human red blood cells (RBCs). Results revealed that Cu and Mn complexes with carboxylates (pivalic acid and benzoic acid) have antimicrobial activities. However, haemlytic assay revealed that the metal complex cytotoxicity was variable and biological activity evaluatuion of newly synthesized metals complexes is suggested for safe applications.

This study looks at using partially purified peroxidase extracted from peels of sweet lime (Citrus limetta) for decolorizing textile industry effluent. The ideal pH and thermal conditions of the enzyme were 7 and 35ºC. The Km and Vmax for guaiacol were 0.66 mM and 6666 μmol/mL/min, respectively. We found that sweet lime peroxidase was very effective in decolorizing textile industry effluent. Almost complete decolorization (>99 %) of effluent was attained at a pH of 5.0, temperature of 55ºC, H₂O₂ concentration of 2 mM, and enzyme dose of 40 U/mL within 60 minutes of incubation. The effluent was also analysed in terms of physicochemical parameters before and after treatment with sweet lime peroxidase. The reduction in toxicity after the enzymatic treatment was evidenced by chemical oxygen demand (COD) and total suspended solids (TSS) values.
