Spiny amaranth leaf extract mediated iron oxide nanoparticles: Biocidal photocatalytic propensity, stability, dissolubility and reusability

Publication date: Available online 21 August 2019Source: Biocatalysis and Agricultural BiotechnologyAuthor(s): M. Harshiny, S. AiswaryaDevi, M. MatheswaranAbstractIn the recent period, nanomaterial with enhanced multifunctional activity and less mammalian toxicity were greatly required. With this perception, the stability, cytotoxicity and antimicrobial, photocatalytic traits of Amaranthus spinosus leaf extract (B-FeO NPs) and sodium borohydride (C-FeO NPs) abridged iron oxide nanoparticles were studied. The analysis results confirmed that B-FeO NPs have better physicochemical characters than C-FeO NPs. The NPs cytotoxicity were tested against MCF-7 cells by MTT assay. The results confirmed that B-FeO NPs cytotoxicity was lesser than C-FeO NPs. The antibacterial and antibiofilm activity of both NPs were tested using Escherichia coli and Bacillus cereus. The outcomes depicted that synthesized NPs have good inclination against E. coli than B. cereus bacteria. The photocatalytic efficiency of NPs was assessed using degradation of naphthalene. The result indicate maximum degradation efficiency of 97% for 40 ppm naphthalene under UV light. These results suggest that B-FeO NPs have better physicochemical traits; also, it can be used as an effective bio-catalytic material in biological Industry.Graphical abstract

The survival rate of MKSR was 98% in 0.1% pepsin solution (pH 2.0) after 3 h, and 93% in 0.1% bile salt solution after 4 h. MKSR possessed strong antibacterial activity against Staphylococcus aureus, Shigella flexneri, Bacillus cereus and Listeria innocua, and antibiotic susceptibility to chloramphenicol. The organism lacked β-glucuronidase catalytic activity ...

To minimize B. cereus food poisoning, propidium monoazide (PMA) combined with quantitative polymerase chain reaction (qPCR) called PMA-qPCR was applied for detecting viable emetic B. cereus in milk. The cereulide synthetase gene of emetic B. cereus (cesB) was chosen for the primer, and PMA trea...

ConclusionThe microfractionation protocol developed in this study enabled time-efficient screening of many plants species, using a small quantity of sample material. In addition, microfractionation served as a guiding tool for identifying individual antimicrobial compounds. Through this process, flavonoids were isolated from Derris scandens, out of which dalpanithin and vicenin-3 showed activity in the low micromolar range. The high hit rate for in vitro antibacterial properties from this ethnopharmacologically guided sample collection gives credence to the Sri Lankan traditional herbal medicine as a source for drug discov...

In this study, a biphasic edible film based on sago starch (SS) and guar gum (GG) was developed, and thereafter, two essential oils (EOs), namely, carvacrol (0.75% w/w) and citral (1.0% w/w) were impregnated either individually or in combination into the blend. The morphology, optical, structural, and water barrier properties of the films were evaluated by various analytical techniques. Scanning electron micrographs exhibited the roughness on the top surface of the EO incorporated blend films, whereas the confocal microscopy confirmed the dispersibility of EOs into the blend. The tensile strength of films significantly red...

Publication date: January 2020Source: Food Control, Volume 107Author(s): Irshaan Syed, Pratik Banerjee, Preetam SarkarAbstractApplication of plant-based essential oils as antimicrobial agents has received considerable attention. However, these antimicrobial compounds undergo quick depletion due to various factors such as volatile nature, low-water solubility, and interactions with lipophilic food components. Therefore, to retain the antimicrobial efficacy of such compounds, the combination with an oil-in-water based emulsion system as a carrier can be a viable option. The current work focuses on the development of geraniol...
