    Nanotechnology is now present in the agricultural and food sectors with nanomaterials such as nanofertilizers and nanopesticides. These nanoparticles may contaminate the environment under certain conditions. The transport, mobility and sorption and bioavailability of nanoparticles is controlled by factors such as soil texture, clay content, pH, cation exchange capacity and soil organic matter. Here we review the fate of nanoparticles in agrosystems. Phytotoxicity of nanoparticles and nanofertilizers are highlighted.

    This work was conducted to investigate the pendimethalin biodegradation by Phanerochaete chrysosporium in aquatic system and different types from soils. P. chrysosporium biomass and atrazine degradation were found to be optimum at pH 7 and 30 °C. Additional carbon sources (i.e., glucose, mannitol and phenol) and nitrogen sources (i.e., ammonium sulfate and sodium nitrate) decreased pendimethalin degradation. P. chrysosporium was able to dissipate 95% pendimethalin in liquid medium at pH 7 and 30 °C after 28 days and its half-life was 6.44 days compared to 53.9 days in uninoculated medium. Results showed also that pendimethalin was degraded faster by P. chrysosporium in sandy soil than clay soil compared to their respective uninoculated soils after 28 days and their half-lives were 4.4, 8.4, 62.43 and 64.7 days, respectively. The degradation of pendimethalin was coinciding with increasing microbial biomass in both pendimethalin contaminated soils comparing with control treatments. This study has shown that P. chrysosporium could be applied to remediate pendimethalin contaminated water and soils.

    A potato wastes powder utilizing bacteria was isolated from soil. Based on morphological, physiological and 16S rDNA, this bacterium was identified as Bacillus subtilis. Inoculation of the solid state culture on potato wastes powder at pH 6.5 with 20% inoculum size of B. subtilis at 30ºC resulted in the maximum biomass and amylase activity. The maximum biomass of B. subtilis and its amylase production was achieved in the stationary phase; -amylase production coincided with the increase in the specific growth rates of the cultures and reduction of starch content in potato wastes powder. B. subtilis was able to degrade starch content in solid potato wastes completely in solid state culture at pH 6.5 and 30 °C after 4 days. Potato wastes powder exhibited different susceptibilities towards amylase to their conversion to reducing sugars. The present study showed also that, the general trend of potato wastes powder bioconversion with B. subtilis amylase was more than the general trend by ...

    A bacterial isolate active in amylase production (designated ES1) was isolated from active sludge using starch as substrate for amylase enzyme. Based on morphological, physiological and 16S rDNA, this bacterium was identified as Bacillus mojavensis. Inoculation of nutrient broth medium supplemented with solid potato wastes at pH 6 with 20% inoculum size of B. mojavensis at 30ºC resulted in the maximum biomass and the highest amylase activity. The maximum biomass of B. mojavensis and its α-amylase production was achieved at the beginning of stationary phase; α-amylase production coincided with the increase in the specific growth rates of the cultures and reduction of starch content in solid potato wastes. B. mojavensis was able to degrade starch content in solid potato wastes completely in liquid medium at pH 6 and 30 °C after 3 days. Different concentration of solid potato wastes which were pretreated with B. mojavensis resulted the highest conversion of starch in potato waste mash ...

    Penicillium italicum, P. digitatum, Botrytis cinerea and Alternaria alternata are consider the most serious pathogenic fungi casing citrus fruit rot diseases during storage. Bacterial antagonists were isolated from surface healthy Navel orange fruits (Washington cv.). These antagonists belong to Pseudomonads and Bacilli which identified as Bacillus subtilis and Pseudomonas sp. In Navel orange fruits pre-treated with the isolated bacteria such as Bacillus subtilis (10 8 cfu/ml), Pseudomonas sp. (10 8 cfu/ml), and commercial product of Trichoderma asperellum (TRIFENDER, 6 g/ml) which used as a biocontrol agent as well as Pharmaplant-turbo (new chemical compound) during the post harvest storage conditions. As a result of using these treatments, disease severity of the artificially inoculated orange fruits with Penicillium italicum and Botrytis cinerea was significantly reduced under room temperature (20-25 • C). The percentage of rotted fruits significantly reduced (from 88-47, 88-66, ...

    Sixteen-year-old navel orange trees at a private orchard located in Kafer El-Sheikh Governorate, Egypt, were used in this study. Compost tea (CT) and filtrate biogas slurry liquid (FLB) were applied at two different concentrations (50% and 100%); control trees were sprayed with water Trees treated with CT at 100% were the highest in yield, fruit weight, and vitamin C, whereas the highest percentage of fruit set, fruit number and soluble solid content (SSC), lowest fruit drop, and highest reducing and total sugars were in trees treated with 100% FLB. Concentrations at 50% for both foliar application (CT and FLB) improved yield and fruit characteristics than control treatment. Generally, using a foliar application of compost tea and filtrate biogas slurry liquid at (100%) treatments as food nutrients could be recommended to improve the yield and fruit quality of navel orange fruits under the current study conditions.

    Various Fenton solutions have been developed for advanced oxidation processes in wastewater treatment. In this study, conventional Fenton solutions such as hydrogen peroxide (HOOH) + Fe(2+) (Mix 1) or HOOH + Fe(3+) (Mix 2), and a new type of solution, HOOH + Fe(3+) + oxalic acid (Mix 3), were used as foliar sprays against powdery mildew on cucumber caused by Sphaerotheca fuliginea. Three Fenton solutions, plus a fungicide, fenarimol, were used to cure and/or protect the plant from powdery mildew under greenhouse conditions. Determination of the ·OH photoformation rate of these Fenton solutions revealed that Mix 3 had a photoformation rate 3.6 - 4.3 times higher than those of Mix 1 and 2. Application of fenarimol and Mix 3 to each plant once a week for three weeks resulted in high curative effects for already-diseased plants. Double spraying with fenarimol and the Mix 3 solutions 1-7 days before S. fuliginea inoculation resulted in the protective effects continuing for up to 20 days after spraying. When the disease reemerged at 20 days post inoculation, one reapplication of the spray suppressed the disease for another 7 days. Overall, fenarimol and Mix 3 were most effective for both the protection and suppression of the disease. These results implied that Mix 3 had fungicidal effects similar to fenarimol; therefore, the use of a Fenton solution such as Mix 3 may offer new possibilities for disease control.

    ABSTRACT A potential method to detoxify pesticides in aquatic system is using bioremediation. In this study, four microorganisms (Pseudomonas sp (EB11), Streptomyces sp. (EB12), Aspergillus niger (EB13) and Trichoderma viride (EB14) were isolated from cucumber leaves previously treated with cymoxanil using enrichment technique. These strains were evaluated for their potential to detoxify cymoxanil in aquatic system at the concentration level of 5×10−4M. The effect of pH and temperature on the growth ability of the tested strains was also investigated by measuring the intracellular protein and mycelia dry weight for bacterial and fungal strains, respectively. Moreover, the remaining toxicity of cymoxanil after 28 days of incubation with tested strains was evaluated to confirm the complete removal of any toxic materials (cymoxanil and its metabolites). The results showed that the optimum pH for the growth of cymoxanil degrading strains (bacteria and fungi) was 7. A temperature of 30°C appears to be the optimum for the growth of either fungal or bacterial strains. Pseudomonas sp. (EB11) was the most effective strain in cymoxanil degradation followed Streptomyces sp (EB12), Trichoderma viride (EB14) and Aspergillus niger (EB13), with half-lives of 4.33, 9.5, 17.3 and 24.7 days, respectively. The degradation of cymoxanil by bacterial strains was much faster than fungal one. There is no remaining toxicity of cymoxanil detected in aqueous media previously treated with Pseudomonas sp. (EB11) for 28 days. The results suggest that bioremediation by Pseudomonas sp. (EB11) are promising for the detoxification of cymoxanil in aqueous media.
