Abstract: The present invention describes capsule compositions consisting of crosslinked chitosan, beta-glucan or alginate, and encapsulates an environmentally compatible insecticide, especially larvicidal agents such as essential oils or essential oil components or other ingestible larvicides such as Bacillus thuringiensis which are lethal to the larvae and adults of pest insects, especially mosquito larvae.

Abstract: A larvicide comprising an essential oil encapsulated within a non-viable yeast cell. The larvicide is particularly effective against mosquito larvae, non-toxic to humans and other non-target species, inexpensive to make, and non-toxic during manufacture, transport, and storage.

Abstract: In one aspect, a fusion antibody specifically binds to a C. difficile virulence toxin. In some embodiments, the C. difficile virulence toxin can include TcdA or TcdB. In some embodiments, the fusion antibody can include a first antibody moiety and a second antibody moiety. The first antibody moiety can include at least a fragment of a first antibody, and the second antibody moiety can include at least a fragment of a second antibody. In another aspect, a recombinant cell expresses the fusion antibody. In another aspect, a recombinant cell has activity that can be modulated by growing the recombinant cell in medium that includes cellobiose. Generally, the recombinant cell includes a heterologous polynucleotide that includes a promoter operably linked to a heterologous coding region, wherein the expression from the promoter is modulated when the recombinant cell is grown in culture medium that comprises cellobiose compared to when the recombinant cell is grown in culture medium that comprises glucose.
