Metallic oxides nanoparticles are stably adsorbed on silicate clay (such as nanosilicate platelets, NSPs) to form the metallic oxide/silicate clay nano-composite. The metallic oxides nanoparticles may be ZnO, CuO, Fe.sub.3O.sub.4, MgO or CaO. Optionally, silver nanoparticles are also adsorbed on the silicate clay for applications. Different from polymer dispersants, the silicate clay has high surface area and charge density so that the metallic oxides are not wrapped and thus perform better bactericidal efficacies.

An extruded animal feed comprising minimally dewatered microalgal biomass and a porous mineral is disclosed. The livestock feed comprises a mixture of the porous mineral, such as zeolite, and a whole algal biomass containing between 2.0% to 15.0% solids. The whole algal biomass and the porous mineral are mixed together at a ratio of 1 part whole algal biomass to between 1 to 3 parts porous mineral. The extruded mixture can be formed by extruding the whole algal biomass and the porous mineral together, with or without additional ingredients. The extruded mixture of whole algal biomass and the porous mineral can be delivered as a feed supplement or can be further processed into a final feed composition. The feed supplement may comprise: Zeolite 2.5% to 12%; Microalgal biomass 1.0% to 7.5%; Flax between 40% to 60%; and a dry feed composition between 35% to 55%.

The disclosure provides a microcapsule including: a core material, an inner membrane, and an outer membrane. The core material includes choline chloride and a carrier. The inner membrane includes at least one vegetable fat having a melting point higher than or equal to 60 C. The outer membrane includes rice bran wax, zinc oxide powders, and a film forming material. The film forming material is glucose phthalate, polyethylene glycol, or sodium alginate. The rice bran wax accounts for 5-10 wt. % of the microcapsule. The mass ratio of the rice bran wax to the zinc oxide powders to the film forming material is 1-5:0.1-1:0.1-1.

The current invention relates to a method of isolating lipids from a lipids containing biomass with aid of hydrophobic silica and to an oil and to a delipidated biomass as obtained by such a method.

Provided herein is a composition comprising a deliverable substance in a matrix for controlled delivery. The composition comprises cellulose micro fibers (CMF), an inert particle substance, and a deliverable substance. This general formula may be applied to a wide range of products, as discussed in detail below. For example, described herein are dog treat compositions comprising cellulose micro fibers which are a substitute for rawhide dog chews. Dog treats made as described herein are very durable and have a wide spectrum of possible sizes, flavors and properties.
