    摘要: Materials composed of inorganic and organic compounds that inhibit, promote and stabilize nanostructured crystalline calcium carbonate for the recruitment and growth of oyster larvae and spat. By using simple chemical precursors in a bottom-up or top-down approach, a variety of layered material compositions can be obtained which result in a standalone material or one that can be applied to and supported by cementitious substrates. The chemical compounds and processes described in this invention are scalable, thus providing for manufacturing small or large quantities of tailored materials, utilizing a variety of techniques, such as but not limited to 3-D printing, spraying, molding and freeze casting to produce a broad spectrum of material compositions and forms suitable for a variety of oyster species and estuarine environments.

    摘要: The present disclosure provides use of sativene, and a recombinant biocontrol fungus and a muscardine cadaver and use thereof, belonging to the technical field of genetic engineering. The present disclosure provides use of sativene in insect attraction and/or pest control. The sativene are attractive to insects. A higher concentration of the sativene has a stronger attraction on mosquito and Drosophila larvae; the Drosophila larvae respond to the sativene even at a level as low as 10−11 g. The sativene also be attractive to Galleria mellonella larvae. The present disclosure further provides a recombinant biocontrol fungus, including a recombinant fungal expression plasmid, where the recombinant fungal expression plasmid is inserted with a pine longifolene synthesis gene. In the present disclosure, the recombinant biocontrol fungus has increased synthetic amounts and volatilized amounts of the longifolene and sativene, resulting in an enhanced attraction to insects.
