Abstract
Present study deals with the green fabrication of copper oxide nanoparticles (CuO NPs) employing cell-free aqueous extract of Cladophora glomerata (L.) Kuetz, freshwater algal species. The UV-visible, FTIR, XRD, FESEM, HRTEM, EDX, BET, XPS and Raman spectroscopic techniques were used to confirm and characterize the biosynthesized CuO NPs. The UV-Vis analysis revealed a sharp peak at 264 nm with a band gap of 3.7 eV, which was attributable to the fabrication of CuO NPs. FESEM and HRTEM detect the spherical-shaped morphology with size between 40 and 50 nm. The biochemical profiling of cell free extract of the C. glomerata by Gas chromatography-mass spectrometry (GC-MS) revealed the presence of various bioactive biomolecules that may acts as a precursor for the fabrication of CuO NPs. The antibacterial study of fabricated CuO NPs revealed significant growth inhibitory potential against selected bacterial strains Klebsiella pneumoniae and Bacillus cereus with an IC50 value of 10 μg/ml. The synthesized CuO NPs also displayed strong DPPH radical scavenging (IC50 value 11.25 mg/L) and total antioxidant (IC50 value 11 mg/L) properties. Further, the anticancer activity of fabricated CuO NPs was studied employing a human hepatocellular carcinoma (HepG2) cell line by MTT assay, which marks their ability to diminish the 50% cell with IC50 value of 168.6 µg/ml. Overall, the findings confirmed that CuO NPs fabricated employing cell-free extract of C. glomerata have the potential to be used as active agent in various biomedical applications after further detailed clinical investigations.
期刊介绍：
Bioprocess and Biosystems Engineering provides an international peer-reviewed forum to facilitate the discussion between engineering and biological science to find efficient solutions in the development and improvement of bioprocesses. The aim of the journal is to focus more attention on the multidisciplinary approaches for integrative bioprocess design. Of special interest are the rational manipulation of biosystems through metabolic engineering techniques to provide new biocatalysts as well as the model based design of bioprocesses (up-stream processing, bioreactor operation and downstream processing) that will lead to new and sustainable production processes.
Contributions are targeted at new approaches for rational and evolutive design of cellular systems by taking into account the environment and constraints of technical production processes, integration of recombinant technology and process design, as well as new hybrid intersections such as bioinformatics and process systems engineering. Manuscripts concerning the design, simulation, experimental validation, control, and economic as well as ecological evaluation of novel processes using biosystems or parts thereof (e.g., enzymes, microorganisms, mammalian cells, plant cells, or tissue), their related products, or technical devices are also encouraged.
The Editors will consider papers for publication based on novelty, their impact on biotechnological production and their contribution to the advancement of bioprocess and biosystems engineering science. Submission of papers dealing with routine aspects of bioprocess engineering (e.g., routine application of established methodologies, and description of established equipment) are discouraged.
