Method for Producing Soyasaponins
20190177360 · 2019-06-13 · ·

Provided is a method for producing soyasaponins inexpensively and simply without crushing seeds or plant bodies and without performing organic solvent treatment. The method for producing soyasaponins comprises bringing at least a part of a plant body of a leguminous plant into contact with an aqueous solution while culturing or cultivating the plant body using the aqueous solution; and collecting the aqueous solution or separating soyasaponins from the aqueous solution.

Microorganisms for Biosynthesis of Limonene on Gaseous Substrates

Engineered microorganisms are provided that convert gaseous substrates, such as producer gas, into limonene. In some embodiments, limonene is pumped out of the cell via an efflux pump. In some embodiments, limonene, produced as described herein, is converted through catalytic dimerization into jet fuel. Producer gas used in the processes described herein for production of limonene may be derived from sources that include gasification of waste feedstock and/or biomass residue, waste gas from industrial processes, or natural gas, biogas, or landfill gas.

USE OF SATIVENE, AND RECOMBINANT BIOCONTROL FUNGUS AND MUSCARDINE CADAVER AND USE THEREOF
20240251802 · 2024-08-01 ·

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.sup.?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.
