    Bioremediation Potential of Trichoderma species for Metal(loid)s
    (CRC Press, 2022-09-30T00:00:00) Kidwai, Mohd. Kashif; Malik, Anju; Dhull, Sanju Bala; Rose, Pawan Kumar; Garg, Vinod Kumar
    Environmental pollution is a global challenge affecting all ecosystems. Various types of pollution are posing challenges to the survival of present and future generations. Inappropriate disposal of heavy metals also causes adverse economical and ecological effects. Microorganisms are omnipresent and deliver significant ecological services in the management of metal(loid)s, enabling them to be applied in various biotechnological strategies for the environmental management needed for sustainable development. Fungal organisms have the innate mechanisms and features such as resistance, tolerance, enzymatic diversity, production of metallothioneins, enzymes and organic acids, enabling them to be applied as potential microorganisms for the remediation of metal(loid)s. Trichoderma species are one among the widely investigated microorganisms and have beneficial applications in the agricultural and industrial sectors. This chapter overviews the contribution of studies conducted on different Trichoderma species and their potential for bioremediation of metal(loid)s such as nickel, cadmium, copper, arsenic, lead, chromium etc. by employing various detoxification strategies such as bioaccumulation, biotransformation, biosorption, phytobial remediation, etc. Various Trichoderma species, T. hrazianum, T. longibrachiatum, T. virens, T. viride etc., are discussed for having bioremediation potential against different metal(loid)s. � 2023 Anju Malik, Mohd.

    Bioremediation: A Sustainable Approach for Environmental Cleanup
    (CRC Press, 2023-10-19T00:00:00) Singh, Bharti; Malik, Anju; Garg, Vinod Kumar
    As the world�s population is increasing by the day, the daily basis demands supplied through industries and agriculture have led to the release of contaminants into the environment resulting in a serious threat to human health and the environment. There are so many technologies for the removal of contaminants from the environment including physical, chemical and sophisticated oxidation procedures. These procedures and technologies, however, have their limitations and the end products are also harmful. As a result, there is a need to identify and investigate sustainable and eco-friendly processes that use less chemicals, are economically viable and provide non-toxic final products. One of the such attractive, stable, sustainable and eco-friendly cleaning technique to deal with this issue is Bioremediation. It is an interdisciplinary approach which includes various living organisms from the surroundings to remediate contaminated ecosystems. Toxic compounds are metabolized by many microbes to release CO2 or CH4, water and biomass. These contaminants may be metabolized enzymatically into less toxic or harmless metabolites. Furthermore, the solid waste produced by this technique has been shown to have a potential influence on soil macro- and micronutrients, indicating its use as organic manure. However, bioremediation requires further research before it could be used on a wider scale, with a focus on the environmental implications of the final products. This chapter provides a brief overview of various bioremediation approaches to remediate the polluted environment. � 2024 Anju Malik and Vinod Kumar Garg.

    Metal(loid)s Sources, Toxicity and Bioremediation
    (CRC Press, 2022-09-30T00:00:00) Kidwai, Mohd. Kashif; Malik, Anju; Garg, Vinod Kumar
    Human-induced unsustainable processes like industrialization, urbanization, modern agriculture etc. are happening all over the globe at the cost of environment affecting all types of life forms in various ecosystems. A variety of pollutants including heavy metals are widely recognised as environmental pollutant or potentially toxic element (PTE) due to their toxic nature and potential to disrupt ecosystem services provided by various organisms. Heavy metals such as nickel, selenium, arsenic, mercury, copper, lead, chromium, and cadmium are metals that pose serious environmental hazards and risks all over the world. Conventional physico-chemical methods are commonly applied in the remediation of heavy metals at a large scale but have several disadvantages. From sustainability point of view, bioremediation is an eco-friendly, non-invasive strategy and comparatively cost feasible than other available conventional methods and provides a sustainable solution for detoxification of various environmental contaminants such as metalloids etc. Both microbially induced remediation and phytoremediation are deeply studied and investigated by various researchers and further applied as per their potential to remediate metal(loid)s, i.e. nickel, selenium, arsenic, mercury, copper, lead, chromium, cadmium and other pollutants. Different bacterial, fungal and algal species are reported for the potential to remediate different toxic metalloids. Diverse plants such as angiosperms, ferns etc. have evolved innate mechanisms as per local environmental conditions enabling them for detoxification of various pollutants through bioremediation. Several plants, bacterial species, fungal species and algal species are reviewed and cited for their role in bioremediation. The chapter is an attempt to briefly introduce the sources, toxicity and various strategies of bioremediation of metal(loid)s involving bacteria, fungi, algae, and plants. � 2023 Anju Malik, Mohd.

    Optimization of Swiss blue dye removal by cotton boll activated carbon: response surface methodological approach
    (Taylor and Francis Ltd., 2021-03-08T00:00:00) Rani, Rekha; Tasmeem, Summaiya; Malik, Anju; Garg, Vinod Kumar; Singh, Lakhvinder; Dhull, Sanju Bala
    Cotton boll activated carbon (CBAC) was employed for Swiss blue (SB) decolorization from simulated wastewater. Adsorption data conformed better with Langmuir adsorption isotherm with highest adsorption capability of 52.631 mg�g?1. Swiss blue adsorption onto CBAC was thermodynamically spontaneous and can be ascribed to follow the pseudo second order (PSO) kinetic model. An experimental matrix based on Box�Behnken design (BBD) of response surface methodology (RSM) was used to design the batch experiments for investigating the adsorption of SB onto CBAC considering four operating factors, viz. initial pH (2�12), contact time (15�150 min), SB concentration (125�375 mg�L�1) and CBAC dose (0.2�1 g/100 mL). RSM-BBD worked successfully to model the process, optimize the factors, and predict SB removal. � 2021 Informa UK Limited, trading as Taylor & Francis Group.
