Item Integrated biohydrogen production via lignocellulosic waste: Opportunity, challenges & future prospects(Elsevier Sci Ltd, 2021-10) Singh, Tripti; Alhazmi, Alaa; Mohammad, Akbar; Srivastava, Neha; Sharma, Shalini; Singh, Rajeev; Yoon, Taeho; Gupta, Vijai Kumar; Haque, Shafiul; Uludağ Üniversitesi/Tıp Fakültesi; EXU-4037-2022; 35793732800Hydrogen production through biological route is the cleanest, renewable and potential way to sustainable energy generation. Productions of hydrogen via dark and photo fermentations are considered to be more sustainable and economical approach over numerous existing biological modes. Nevertheless, both the biological modes suffer from certain limitations like low yield and production rate, and because of these practical implementations are still far away. Therefore, the present review provides an assessment and feasibility of integrated biohydrogen production strategy by combining dark and photo-fermentation as an advanced biochemical processing while using lignocellulosics biomass to improve and accelerate the biohydrogen production technology in a sustainable manner. This review also evaluates practical viability of the integrated approach for biohydrogen production along with the analysis of the key factors which significantly influence to elevate this technology on commercial ground with the implementation of various environment friendly and innovative approaches.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.
