The Bio-Synthesis of Three Metal Oxide Nanoparticles (ZnO, MnO2, and MgO) and Their Antibacterial Activity Against the Bacterial Leaf Blight Pathogen

“…The absence of peaks in the bulk solutions of ZnO, MgO, and MnO 2 indicates the absence of nanoparticles in the bulk solutions which is consistent with the reports of Abdallah et al (2020). The UV peak of 385, 230, and 230 nm, respectively, for ZnO, MgO, and MnO 2 nanoparticles recorded in this study is consistent with our previous study of biosynthesis of MgO and MnO 2 nanoparticles (Ogunyemi et al, 2019a), while Abdallah et al (2019bAbdallah et al ( , 2020 recorded a different peak for ZnO and MgO nanoparticles. In the study of Salunke et al (2015), a peak of 365 nm was observed for MnO 2 nanoparticles.…”

“…In this study, the synthesis procedure started from respective metal oxide rather than the salt precursor because of its relative non-toxicity as compared to salt precursor which are very toxic (Stoimenov et al, 2002;Jones et al, 2008;Sundrarajan et al, 2012). Metal oxides can also adopt a vast number of structural geometries with unique physical and chemical properties (Montero et al, 2010;Lakshmi et al, 2012;Mirzaei and Davoodnia, 2012;Divyapriya et al, 2014;Tang and Lv, 2014;Moon et al, 2015;Ogunyemi et al, 2019a). The synthesis protocol used in this study was adopted because it is cheap and eco-friendly.…”

Advancements in Plant and Microbe-Based Synthesis of Metallic Nanoparticles and Their Antimicrobial Activity against Plant Pathogens

“…Moreover, it requires less energy and has easy and broader implications [ 130 ]. The green synthesis of NPs mediated by plant extracts involves the alleviation of metal ions [ 131 ] due to the presence of biomolecules such as phenols, terpenoids, ketones, carboxylic acids, aldehydes, enzymes, amides, and flavonoids [ 130 , 132 , 133 , 134 , 135 ]. The plant extracts prepared from their different parts such as roots, stems, barks, leaves, flowers, fruits and seeds have been used for green synthesis of NPs [ 136 , 137 , 138 , 139 , 140 , 141 , 142 ].…”

Green synthesis of Bryophyllum pinnatum aqueous leaf extract mediated bio-molecule capped dilute ferromagnetic α-MnO2 nanoparticles

“…Green synthesis methods using leaf extract as the source of both the reducing and capping agents might be a potential candidate for the synthesis of α-MnO 2 nanoparticles. Reports on the green synthesis of MnO 2 nanoparticles using leaf/plant/peel extracts of Yucca gloriosa [21], Matricaria chamomilla L. [22], Brassica oleracea [23], and lemon peel [24] are available. In the present study, it was aimed to establish an environmentally friendly route for the synthesis of bio-molecule capped α-MnO 2 nanoparticles using Bryophyllum pinnatum aqueous leaf extract as a reducing and capping agent and subsequently evaluate their physicochemical property.…”
