    Functional characterization of microbes and their association with unwanted substance for wastewater treatment processes
    (Elsevier Ltd, 2023-07-06T00:00:00) Swapnil, Prashant; Singh, Laishram Amarjit; Mandal, Chandan; Sahoo, Abhishek; Batool, Farida; Anuradha; Meena, Mukesh; Kumari, Pritee; Harish; Zehra, Andleeb
    Nowadays, microorganisms can be used to eliminate a variety of pollutants such as toxic metal ions from wastewater. These emergences of harmful elements in wastewater, high-priced cultivation of microbes and technical hitches in industrial scale production appeared as main challenges for thriving coupling of microbes with wastewater. These microbes serve as potential sorbents by following suitable adsorption mechanisms. There are some photobioreactors have been also mentioned in this review which is based on microbial biofilm and emerged as an alternative technology to predictable photosynthetic systems for treatment of wastewater based on biomass production at low cost. Bioremediation using different microbes showed contrast results to remove heavy metals from wastewater. Microorganism such as Nostoc sp., Aspergillus versicolor, Aspergillus lentulus and Aspergillus niger remediate 99.6, 99.89, 99.7 and 98 % of Pb, Cr, Cu and Ni, respectively. In this review, mechanistic approaches and distinct pathways of the microbes for removal of various inorganic and organic compounds from wastewater have been methodically discussed. We have also discussed some major commercial production challenges such as techno-economic feasibility genetic engineering research and biorefinery approach. Overall the review discussed the microbial biodiversity in wastewater and their role in remediation of wastewater and their ability to be a potent candidate headed for sustainable industrial wastewater treatment applications through different approaches such as phytoremediation and bioremediation. This article provides valuable insights into multiple aspects of environmental biotechnology, including photobioreactors, metal uptake capacity of microorganisms, heavy metal contamination and its effects and bioremediation using molecular approaches and wastewater treatment through phytoremediation. Moreover, it contributes to our understanding of these topics and can help in the development of sustainable solutions for environmental remediation and pollution control in wastewater though microorganisms. � 2023 Elsevier Ltd

    Arctic biodiversity amidst looming climate apocalypse: Current status and way forward
    (Elsevier, 2021-08-27T00:00:00) Rani, Alka; Gupta, Kriti; Saini, Khem Chand; Narwal, Sahil; Bast, Felix
    Arctic region is at the forefront of climate crisis; this is where the planet is warming maximally and the effects of climate change are most obvious. In this review, we introduce the topic in broader perspective by discussing first on why Arctic biodiversity matters, and scientific evidences for a changing Arctic biodiversity due to climate change. The Arctic then dwells into the current status of Arctic biodiversity covering species diversity and its conservation status with an emphasis on species important for bioprospecting. Subsequently, threats to Arctic biodiversity will be reviewed including climate change, shipping, oil exploration, overfishing, and overharvesting. This essay would then further deliberate why Arctic matters to India in particular. Himadri-Indian research station at Svalbard, Norway-will be briefed followed by an overview of Svalbard Global Seed Vault and why signing a pact with this international facility would benefit the country. The essay concludes with final thoughts and way forward including strategies to minimize Arctic biodiversity loss, UN SDGs (Ssustainable Ddevelopment Ggoals), and climate action. � 2021 Elsevier Inc.
