    • Wed, 11/16/2022 - 04:00
    • Frontiers in Microbiology
    • Fusarium oxysporum is the main pathogen of Panax notoginseng root rot, and chemical fungicides remain the primary measures to control the disease. Plant essential oil (EO) is a volatile plant secondary metabolic product that does not produce any residue to replace chemical pesticide. To comprehensively understand the antifungal mechanism of Alpinia officinarum Hance EO, the physiological indicators, proteome and metabolome were analyzed using F.

    • Frontiers in Microbiology
    • Strawberry gray mold caused by Botrytis cinerea is one of the most severe diseases in pre- and post-harvest periods. Although fungicides have been an effective way to control this disease, they can cause serious “3R” problems (Resistance, Resurgence and Residue). In this study, Streptomyces sp. sdu1201 isolated from the hindgut of the fungus-growing termite Odontotermes formosanus revealed significant antifungal activity against B. cinerea.

  8. Whole Genome Sequencing Reveals Biopesticidal Origin of Bacillus thuringiensis in Foods

    • Wed, 01/12/2022 - 22:17
    • Frontiers in Microbiology
    • Bacillus thuringiensis is a microbial insecticide widely used to control agricultural pests.

  10. Tapping the Role of Microbial Biosurfactants in Pesticide Remediation: An Eco-Friendly Approach for Environmental Sustainability

    • Thu, 12/23/2021 - 16:00
    • Frontiers in Microbiology
    • Pesticides are used indiscriminately all over the world to protect crops from pests and pathogens. If they are used in excess, they contaminate the soil and water bodies and negatively affect human health and the environment. However, bioremediation is the most viable option to deal with these pollutants, but it has certain limitations. Therefore, harnessing the role of microbial biosurfactants in pesticide remediation is a promising approach.
