A coat protein of Junonia coenia densovirus (JcDNV) is used to deliver attached peptide insect toxin across the gut epithelium of a fall armyworm, Spodoptera frugiperda. A fusion protein comprising VP4 attached to an insect toxin via a peptide linker is developed. A composition comprising a JcDNV coat protein attached to an insect toxin via a peptide linker can be used for insect pest control.

The inventive technology relates to novel paratransgenic strategies for the control of pathogens. The inventive technology may specifically include a novel paratransgenic system configured to deliver one or more inhibitory RNA molecules to pathogen/disease-transmitting organisms. In a preferred embodiment, the invention may include one or more genetically engineered symbiotic bacteria configured to persist throughout the life-cycle of a mosquito and deliver one or more interfering RNA molecules to pathogen/disease-transmitting mosquitoes.

In aspect, a ready-to-use liquid larvicide composition comprises, consists essentially of, or consists of Bacillus thuringiensis (Bt) fermentate, propionic acid, and water. In other aspects, a composition comprises a fragrance and/or oil, a surfactant, an aqueous medium, and a larvicide.

The subject invention provides methods for cultivating Starmerella bombicola yeasts for sophorolipid production, as well as a yeast fermentation product comprising supernatant, yeast cell biomass and other residual growth by-products that result when the sophorolipids are harvested. Methods of using this yeast fermentation product in animal feed, bioremediation, mining and/or bioleaching, agriculture, oil and gas recovery, human health, and many other applications, are also provided.

The present disclosure relates, in some aspects, to bile acid sensors.

A method of treating or preventing a microbial infection in a subject is described. The method includes contacting a microorganism within the subject with a composition comprising one or more species of amoebae of the genus Willaertia. Antibiotic wound dressings and kits for providing amoeba for treatment or prevention of microbial infection in a subject are also described.

The invention relates to methods, uses, systems, arrays, engineered nucleotide sequences and vectors for inhibiting bacterial population growth or for altering the relative ratio of sub-populations of first and second bacteria in a mixed population of bacteria. The invention is particularly useful, for example, for treatment of microbes such as for environmental, medical, food and beverage use. The invention relates inter alia to methods of controlling microbiologically influenced corrosion (MIC) or biofouling of a substrate or fluid in an industrial or domestic system.
