NOVELTY - Process for recovering an oil product (I) from an organism, comprises: obtaining a crude extract from an organismal biomass; applying the crude extract to a composition comprising a nanomaterial; and recovering the oil product from the composition comprising the nanomaterial.    USE - The purified oil is useful in transesterfication as a bio-diesel or bio-gasoline (claimed). The process is useful to purify crude extracts from terrestrial plants, aquatic plants and microorganisms such as algae.    ADVANTAGE - The process is economically viable for production of oil from organisms, including plants and microorganisms such as algae. The process produces a purified oil end product, which is free from contaminants such as residual pigments from the initial organisms.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a process for recovering triglycerides or an organic pigment, comprising: obtaining a crude extract from an organismal biomass; applying the crude extract to a composition comprising a nanomaterial; and recovering the triglycerides or the organic pigment from the composition comprising the nanomaterial;    (2) a process for producing a biofuel, comprising: obtaining a crude extract from an organismal biomass; applying the crude extract to a composition comprising a nanomaterial; recovering the oil product from the composition comprising a nanomaterial; and converting the purified oil product by transesterification into biodiesel or biogasoline;    (3) a composition comprising an extract of an organism and a nanomaterial;    (4) a process for recovering a carotenoid, comprising: obtaining a crude extract containing many organic pigments from an organismal biomass; applying the crude extract containing organic pigments to a composition comprising a nanomaterial, where the composition comprising the nanomaterial selectively absorbs at least one organic pigment that is not a carotenoid from the crude extract; recovering the obtained liquid extract by removing the composition comprising the nanomaterial from the crude extract; and isolating a carotenoid from the liquid extract; and    (5) a process for recovering a lipid-containing oil product from an organism, comprising: mixing an organismal biomass with a water-immiscible solvent to produce a crude extract of the biomass, which contains lipid and the water-immiscible solvent; adding a nanomaterial to the crude extract, where the nanomaterial absorbs the lipid, the water-immiscible solvent and at least one organic pigment; isolating the nanomaterial from the rest of the crude extract; and recovering a lipid-containing oil product from the isolated nanomaterial, where the lipid-containing oil product is substantially free of chlorophyll.
