Publication Sustainable green approach to synthesize Fe₃O₄/α-Fe₂O₃ nanocomposite using waste pulp of Syzygium cumini and its application in functional stability of microbial cellulases(Nature Portfolio, 2021-12-21) Srivastava, Neha; Srivastava, Manish; Alhazmi, Alaa; Mohammad, Akbar; Khan, Saif; Pal, Dan Bahadur; Haque, Shafiul; Singh, Rajeev; Mishra, P. K.; Gupta, Vijai Kumar; Haque, Shafiul; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-2989-121X; AAN-2946-2020Synthesis of nanomaterials following green routes have drawn much attention in recent years due to the low cost, easy and eco-friendly approaches involved therein. Therefore, the current study is focused towards the synthesis of Fe₃O₄/alpha-Fe₂O₃ nanocomposite using waste pulp of Jamun (Syzygium cumini) and iron nitrate as the precursor of iron in an eco-friendly way. The synthesized Fe₃O₄/alpha-Fe₂O₃ nanocomposite has been extensively characterized through numerous techniques to explore the physicochemical properties, including X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, Ultraviolet-Vis spectroscopy, field emission scanning electron microscope, high resolution transmission electron microscope and vibrating sample magnetometer. Further, efficiency of the Fe₃O₄/alpha-Fe₂O₃ nanocomposite has been evaluated to improve the incubation temperature, thermal/pH stability of the crude cellulase enzymes obtained from the lab isolate fungal strain Cladosporium cladosporioides NS₂ via solid state fermentation. It is found that the presence of 0.5% Fe₃O₄/alpha-Fe₂O₃ nanocomposite showed optimum incubation temperature and thermal stability in the long temperature range of 50-60 degrees C for 15 h along with improved pH stability in the range of pH 3.5-6.0. The presented study may have potential application in bioconversion of waste biomass at high temperature and broad pH range.
