  • Publication number: 20240385091
    Abstract: The present disclosure provides a method of detecting the presence of and/or the amount of at least one fungal plant pathogen in a sample. The method comprises contacting the at least one fungal plant pathogen with at least one biological component that specifically binds to the at least one fungal plant pathogen in a liquid sample, detecting, such as imaging and/or measuring the impedance of, at least a portion of the liquid sample, and correlating the detection with the presence and/or the amount of the at least one fungal plant pathogen in the liquid sample. The present disclosure also provides a sample trap device for performing the method.

  • Publication number: 20230112998
    Abstract: The present disclosure provides a biosensor for detecting the presence of and/or the amount of at least one fungal plant pathogen in a sample, comprising: a support structure; at least two interdigitated electrodes coupled to the support structure, wherein at least one of the interdigitated electrodes is functionalized with a linker coupled to at least one biological component that recognizes the at least one fungal plant pathogen; and an impedance measurement circuit coupled to the at least two interdigitated electrodes. The present disclosure also provides methods of detecting the presence of and/or the amount of at least one fungal plant pathogen in a sample, methods of making the biosensor described herein, as well as methods and uses of using the herein described biosensor for detecting the presence of and/or amount of at least one fungal plant pathogen.

  • Patent number: 11260377
    Abstract: This application consists of a method for the synthesis of a type of FER/MOR composite molecular sieve. That method consisting of mixing FER seed crystals, MOR seed crystals, a silicon source, water and an acid or alkali, thus yielding a reaction mixture; by adjusting the proportions of the seed crystals added, the silicon-aluminium proportion, acidity/alkalinity and other reaction conditions, it is possible to obtain a dual phase composite molecular sieve within which the proportions of the crystal phases may be adjusted. In the synthesis process to which the method of this application relates, there is no need to add any organic template, thus reducing the cost of the reaction, in addition to reducing likely environmental pollution, thus having major potential applications.

  • Publication number: 20070191228
    Abstract: A natural herbicide comprising a Burkholderia species cell-free culture fraction having herbicidal activity is provided. The natural herbicide may comprise a cell free fraction having a molecular weight less than about 5000 Daltons, less than 1000 Daltons, or a substantially purified compound having a molecular weight of about 192 Daltons or about 390 Daltons. A method of suppressing or controlling growth of a target plant by applying a composition comprising the natural herbicide is also provided, as is a method of producing a natural herbicide. The natural herbicide may be produced by obtaining a cell-free culture conditioned by growth of a Burkholderia species, fractionating the cell-free culture to obtain a fraction having herbicidal activity, and purifying the fraction having herbicidal activity to produce the natural herbicide.
