NOVELTY - A bioprocess reactor comprises a cellulosic carbon source having a cellulose degrading fungus growing on it, the cellulosic carbon source present in a liquid medium, the cellulose degrading fungus growing in a liquid medium, the liquid medium comprising a carbon source and a nitrogen source, where the ratio of carbon to nitrogen in the medium is 1:1 to 1000:1, and the fungus comprises at least 5% triacylglyceride by dry weight.    USE - The bioprocess reactor is used for manufacturing co-products. The co-products are selected from aromatic compounds, lipid co-products, secreted metabolites, residual solid feedstock, reconditioned medium, fungal biomass, and their combination. The lipid co-product comprises a triacylglyceride co-product and a phospholipid co-product. The fungal biomass is used for manufacture of an animal feed, feeding an animal, improving the longevity of an animal, and increasing the resistance of an animal to an infection (all claimed).    ADVANTAGE - The present invention provides microbial and chemical systems to convert biomass to commodity chemicals, such as biofuels/biopetrols.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are: (1) a process for manufacturing co-products by (a) inoculating a bioprocess reactor with an inoculum of a cellulose degrading fungus, (b) allowing a sufficient time for production of triacylglyceride by the fungus, where the triacylglyceride comprises at least 5% of the dry weight of the fungus, (c) harvesting the fungus, and (d) extracting lipids from the fungus, thus producing a lipid co-product; (2) a facility comprising a vessel for holding liquid medium conditioned by a cellulose degrading fungus; an extraction apparatus comprising an extract of lipids comprising any one or more of triacylglyceride, phospholipids or lecithin derived from the fungus; and a drying apparatus comprising dried fungus; (3) a filtration apparatus comprising a filter housing having a filtration surface disposed in it, and a mycelial mat of a cellulose degrading fungus dispersed on the filtration surface; (4) a bioprocessing facility for producing co-products, comprising bioprocess reactors comprising a cellulose degrading fungus of the genus Penicillium growing in a liquid medium, the liquid medium comprising a carbon source and a nitrogen source, where the ratio of carbon to nitrogen in the medium is 1:1 to 1000:1; (5) an admixture comprising fungal biomass and whey; (6) a method of manufacture of an animal feed by combining dried fungal biomass with whey, thus forming an admixture; (7) a method of feeding an animal by providing to the animal a feed composition comprising a fungal biomass derived from a cellulose degrading fungus; (8) a method of improving the longevity of an animal by identifying an animal in need of having improved longevity; and providing to the animal an animal feed comprising fungal biomass derived from a cellulose degrading fungus of the genus Penicillium; and (9) a method of increasing the resistance of an animal to an infection by identifying an animal in need of increased resistance to an infection; and providing to the animal an animal feed comprising a fungal biomass derived from a cellulose degrading fungus of the genus Penicillium.
