The antimicrobial effects of pure EOs of four spices and chitosan-EOs films on L. monocytogenes and E. coli were evaluated in vitro by agar diffusion test [49]. The EO of thyme showed the highest antibacterial activities, with the widest inhibition zones and the lowest MICs (0.3121.25 L/mL), and B. cereus was the most sensitive bacterium tested. Low dose irradiation has also proved to be effective for fish preservation when applied in combination with chilling or heating processes. Garlic hydrosols demonstrated stronger antibacterial activities than other spices hydrosols. Aygun A, Glbagca F, Ozer LY, Ustaoglu B, Altunoglu YC, Baloglu MC, et al. Mediator-free microbial fuel cells use electrochemically active bacteria such as Shewanella putrefaciens and Aeromonas hydrophila to transfer electrons directly from the bacterial respiratory enzyme to the electrode. This shows that Ag NPs produced by these plants have much higher content of biomolecules on their surface than Ag NPs produced by Daphne mucronate. Coriander was widely applied in producing chutneys and sauces, flavoring pastry, cookies, buns, and tobacco products, and extensively employed for preparation of curry powder, pickling spices, sausages, seasonings, and food preservatives [4,118]. Antimicrobial activity of coriander oil and its effectiveness as food preservative. Nine pathogens were isolated from seven of the 22 patients, including K. pneumoniae (3 patients), Haemophilus influenzae (2 patients), Bifidobacterium (1 patient), Enterococcus faecium (1 patient), M. tuberculosis (1 patient), and Shewanella putrefaciens (1 patient). Geochemistry, Geophysics, Geosystems, 2012, 13(Q10Z51), doi:10.1029/2012GC004384. Due to inappropriate wastewater discharge and waste disposal, large amounts of Cd are released to surrounding soil and water as a divalent form (Cd(II)) (Kubier et al., 2019).Usually, free Cd(II) in water is deposited on sediment and the enriched Cd(II) will be Ceramic NPs are inorganic solids made of carbonates, carbides, phosphates, and oxides of metals and metalloids, such as titanium and calcium [46]. 8600 Rockville Pike Elsevier; 2015. p. 585608. Examples: For the characterization of Ag NPs produced by Rhodomyrtus tomentosa leaf extract, DSC showed three exothermic peaks at 44, 159, 243, and an endothermic peak at 441C. Qin HF, Zhao X, Liu SC, Paterson GA, Jiang ZX, Cai SH. Clove products had the strongest antimicrobial activities compared with other spices tested. Examples: The zeta potential is a good indicator for the stability of NPs, where NPs with zeta potentials of more than+30mV or less than 30mV are considered stable. Peptone water (0.1%) is used as a diluent, as phosphate may reduce cell recovery. In these cases, the farmers usually react by using excessive amounts of fertilizers, which increases crops productivity but has an environmental cost [288]. California Privacy Statement, In recent studies, thyme was found to possess efficient antimicrobial activities and was used in some foods to extend the shelf-life [50]. The researchers found a frequency dependence for storage modulus, loss modulus, and loss tangent for the nanocomposite with various Ag NPs loading concentrations. Examples: NTA was used to measure the size and dispersity of Ag NPs produced by Camellia sinensis (green tea) powder, the NPs were found to be well dispersed in an aqueous medium with an average size of 4512nm [147].

Do not breathe spray or mist. Silva F., Domingues F.C. If the dimensions differ significantly (typically by more than three times), terms such as nanofibers or nanoplates maybe preferred to the term NPsFootnote 2. Figure6 graphically illustrates this method. Determination of size and mass-and number-based concentration of biogenic SeNPs synthesized by lactic acid bacteria by using a multimethod approach. Larger surface areas and larger surface-to-volume ratios generally increases the reactivity of nanomaterials due to the larger reaction surface [1], as well as resulting in significant effects of surface properties on their structure [17]. Microwave and conventionally roasted oils exhibit similar antimicrobial effects but were higher effect than raw oils. BET was also used to measure the surface area of SiO2 NPs produced by rice husk, CuO NPs produced by Leucaena leucocephala leaf extract, and Ag NPs produced by Acanthospermum hispidum leaf extract. Shewanella spp. In both cases, the zero-oxidation state was the abundant one, the presence of a small amount of the other oxidation states suggests that some of the NPs were oxidized or had unreduced species [173, 174]. 2015;117(17):17A503. Mastronardi E, Tsae P, Zhang X, Monreal C, DeRosa MC. The antimicrobial activities of cinnamon were evaluated in some studies. Cinnamon aqueous extract was the only one to inhibit all the tested microorganisms at the concentration of 1% w/v. (2021). [42] Li Q, Zhang Q, Li GX, Liu QS, Chen MT, Xu JS. NP size effects can also be observed in changes in magnetic coercivity, i.e., the resistance of a magnetic material to changes in magnetization (Fig. High-resolution enviromagnetic records of the last deglaciation from Dali Lake, Inner Mongolia. There are three types of drying are used for fish preservation sun drying, vacuum drying, and freeze-drying. However, large differences in coercivity were found between a set of cubic and spherical CoFe2O4 NPs [91]. Talanta. 2012;35:6470.

Oregano EO was the most effective against, The MICs of oregano EO ranged from 0.5 to 1100 g/mL for all tested, 7 spice EOs and the majority constituents. XPS is based on the photoelectric effect that can identify the elements within a material, or covering a material, as well as their chemical state with high precision [170]. Antimicrobial herb and spice compounds in food. The ethyl heptanoate extract of clove film also possessed antibacterial activities against all tested bacteria, weaker than those of clove EO though. and Corynebacteria are found in any number, though thermoduric micrococci and lactococci are occasionally recovered. Mediator-free MFCs are less well characterized, such In studies, it has been shown that irradiation doses of 1.0 to 2.0 kGy were able to eliminate contaminant microorganisms in raw fish. Clove water extract was the most effective among all the water extracts with the MIC ranging from 0.1% to 0.2%. Surimi is a product prepared from either deboned meat or fillet.

Cumin EO was the second effective against bacteria tested with DIZs ranging from 31.23 mm (L. sakei) to 38.17 mm (E. gergoviae). Cumin (Cuminum cyminum) is an aromatic plant belonging to the Apiaceae family. A similar behavior was also found in the decomposition of SO2 and dissociation of water by Au NPs supported on CeO2, in which CeO2 supports played a critical role [131]. J Energy Chem. Psychrotrophic bacteria such as P. putrefaciens can also cause unpleasant deteriorations on the butters surface, known as surface taints with a peculiar smell specific to organic acids, and the appearance of rancidity caused by the hydrolysis of the fats (Jay, 2005). As indicated earlier, phospholipase action can destroy the native MFGM, resulting in destabilisation of the fat emulsion in milk. Khlebtsov NG, Dykman LA. [96] tested the antimicrobial activities of aqueous extracts from 5 spices against 8 Gram-positive bacteria and 12 Gram-negative bacteria by the disc diffusion assay. Bacillus, Clostridium, Escherichia, Micrococcus, Proteus, Sarcina, For unpreserved fish, spoilage is caused by Gram-negative, fermentative bacteria (such as, ), whereas psychrotolerant Gram-negative bacteria (such as, The fish spoilage is also caused by psychrotrophic, aerobic, or facultative anaerobic Gram-negative bacteria such as, Acinetobacter, Shewanella putrifaciens, Vibrio, Flavobacterium, Photobacterium, Staphylococcus spp., Micrococcus, Bacillus, Clostridium, Corynebacterium, Brochothric thermosphacta, Lactic acid bacteria (LAB) can predominate in fish storage under vacuum or CO, Some parasites can also be transmitted by fish, including tapeworm (. Touba et al. 1999;146(10):3750. Therefore, their detection in pasteurized products is an indication of postpasteurization contamination. Int J Mater Sci Eng. doi: http://dx.doi.org/10.1093/femsle/fnv167. 2. These enzymes can jeopardize the quality of stored raw chilled milk, and cause undesirable alterations in taste and smell and dark taints in the condensed milk, fermented milk, fresh cheese, and butter (Jay, 2005; Pinto et al., 2013). Similarly, this approach revealed that Ag NPs produced by Andrographis paniculata stem extract were coated with an organic polymer [168].
