ABSTRACT. Magnetic nanoparticles (MNPs) are gaining popularity because of their small size allowing for research into the fundamentals of magnetism. In wastewater treatment, adsorption methods commonly remove heavy metals, but copper (Cu+2) ion removal using magnetic nanoparticles (NPs) has not been investigated. In this study two different modes were used to determine maximum adsorption capacity to remove copper(II). The nanoparticles containing the Fe3O4 with Chlorella, core-shell Fe3O4/SiO2 with Chlorella sp. synthesized and characterized by Fourier transform infrared (FT-IR) analysis, the morphology observed by scanning electron microscope (SEM), crystalline structure, and grain size provided by energy dispersive X-ray (EDX) and X-ray diffraction (XRD). Copper(II) ion removal showed in both modes. The maximum copper(II) ion reduction percent was obtained by nanoparticles containing core-shell Fe3O4/Chlorella 80.3%, Fe3O4/SiO2 with Chlorella sp. (86.9%) the result showed maximum removal using Fe3O4/SiO2 with Chlorella sp. due to increase of surface area. The results indicate that the adsorption using magnetic nanoparticles with Chlorella sp. enhances the cell surface and provides easy access to the separation for both preparation and recapture.

تمتلك الطحالب الدقيقة, نظرأ لسهولة زراعتها ونموها السريع وتجددها, امكانات كمصدر للمركبات النشطة بيولوجيأ للاغراض الصناعية والطبية. تهدف هذه الدراسة التي اجريت بشكل (in vivo) الى تقيم القدرة المضادة للاغشية الحيوية والسموم الحيوية لطحالب الدقيقة مختارة وعزلات البكتريا الزرقاء. تم اختيار تراكيز مختلفة من عزلات الطحالب الدقيقة في كل من دراسات المضادات الحيوية والخلاية السامة . تمت اضافة مستخلص اجمالي قدره 10 ميكروليترمنMTT الى كل بئر باستخدام مرقLB , وتمت قراءة اللوحات باستخدام مقياس الطيف الضوئي للوحة ميكروتيتر عند 490 نانوميترو 630 نانوميتر, على التوالي. تم تحديد بقاء قدرة الخلية في خلايا CCD-18Co (3x103 cells/well) بواسطة اختبار MTTعند 590 نانوميتر. اظهرت عزلات الطاحالب الدقيقة تاثير مضاد حيوي بعد 48 ساعة على Pseudomonas aeruginosa PA01 ولوحظ ان هذا التاثير اعلى من تاثيره على S. aureus. Chlorella sp. اظهر الحد الاقصى لنشاط المضاد الحيوي بينما لم يكن لدى Arthrospira platensis اي نشاط تثبيط للاغشية الحيوية. Chlorella sp. تثبط حوالي %82.67 من الغشاء الحيوي في تركيز 5 ملغم \مل . علاوة على ذلك فان التاثيرات المضادة للاغشية الحيوية ل (Chara sp. و Spyrogyra sp.1) وصلت بنسبة الى %79.01 و %76.31 عند 1 ملغم\مل على التوالي. من بين جميع العزلات الطحالب الدقيقة, لوحظ وجود تاثير مثبط معتدل على الاغشية الحيوية ل Pseudomonas aeruginosa مع Chlorella sorokiniana . لم تتغير قابلية الخلية للبقاء بشكل ملحوظ في مستخلصات جرعات عالية. اكثر من %73 من الخلايا كانت قابلة للحياة في جميع تركيزات مستخلصات الطحالب. وجد بان جميع عينات الطحالب الدقيقة لها نشاط تثبيط الاغشية الحيوية. تشير النتائج الى ان التطوير المستقبلي لعينات الطحالب الدقيقة كوسيلة لتثبيط الاغشية الحيوية ل Pseudomonas aeruginosa امر ممكن. قد تصبح الخلاية الطلائية القولونية خلاية سامة استجابة لمستخلصات الطحالب. من الضروري اجراء المزيد من الابحاث للتحقق من ان المستخلصات أمنة للاستهلاك البشري, وهو ما يكون مفترضأ.

“…The expressive antioxidant capacity of the bark of P. platycephala can be attributed to some compounds such as: (Z)-9-octadecenamide and octacosanol, are present in BEE, trilinolein is present in BME, and ferulic acid, caffeic acid, and 1,2,3-benzenetriol are present in both extracts. Anwer et al (2022) asserted that (Z)-9-octadecenamide is one of the representatives of fatty acids with relevant antioxidant capacity. Recent studies corroborate this perception (Emre and Kursat, 2022) through the application of bioinformatics methods aimed at predicting the pharmacokinetics of (Z)-9-octadecenamide.…”

Parkia platycephala is the only species of the genus Parkia that is endemic to the brazilian Cerrado and the tree symbol of the state of Tocantins, but there are still few studies regarding its bioprospecting. In this study, we aimed to investigate the phytochemical composition, toxicity and bioactivities of the bark and flower of Parkia platycephala. Hot sequential extractions (Soxhlet) were performed using methanol and hydroethanolic solution (70%), after degreasing the sample (hexane). The presence of flavonoids, tannins, steroids and alkaloids was detected in the preliminary screening. Trilinolein, (Z)-9-octadecenamide, 3-O-methyl-d-glucose were detected by Gas Chromatography coupled to Mass Spectrometry (GC-MS). In the Liquid Chromatography with Diode Array Detector (LC-PDA) analysis, it was detected exclusively ferulic acid (bark) and ellagic acid (flower). The ethanolic extract of the bark (IC50=10.69 ± 0.35 µgmL-1) has an antioxidant potential (DPPH• radical) higher than that of the rutin standard (IC50=15.85 ± 0.08 µgmL-1). All extracts showed excellent anticholinesterase potential (Ellman), with emphasis on the ethanol extract of the flower (IC50 =5.34 ± 0.12 µgmL-1). Regarding toxicity (Artemia salina), the methanolic extract of the bark and the ethanolic extract of the flower presented high and moderate levels, respectively. Such results limit the concentrations of biological activities in this study, however, the antioxidant and anticholinesterase indices fall short of toxicity. The results demonstrated promising antioxidant and anticholinesterase activities of both the bark and the flower of Parkia platycephala.
