NOVELTY - Producing (P1) enzymes and lipids involves: introducing organic material from pulp and/or paper industry into the single cell oil production process; producing lipids or lipids and enzymes by a microorganism capable of producing lipids or lipids and enzymes; separating supernatant and microorganism cells from the microorganism culture; recovering lipids; and recovering the supernatant or a protein enriched fraction of the supernatant or a dilution of the supernatant comprising catalytically active enzymes and optionally introducing it or them into the pulp and/or paper industry process.    USE - As integrated process for producing enzymes and lipids. The enzymes comprise hemicellulases, xylanases, mannanases, galactosidases, peroxidases, laccases, pectinases, cellulases, glucosidases, arabinases, lipases, amylases, esterases or proteases. The enzymes comprise exoenzymes, preferably enzymes associated with hemicellulose hydrolysis or cellulose hydrolysis. The enzyme and enzyme preparation obtained by the method is used in pulp and paper industry or in other application as an enzyme preparation or as a source of enzymes. The lipids and the enzyme preparation obtained by the method is used as biofuel (preferably biodiesel or renewable diesel, gasoline and jet fuel) or as a component of biofuel or as a starting material for biofuel production. The hemicellulases used in pulp (pre)bleaching, enhancing dissolving pulp process, enhancing Kraft pulp process, debarking, deinking and fiber modification, preferably in(pre)bleaching. The cellulases used in deinking, fiber modification, enhancing dissolving pulp process, enhancing Kraft pulp process and debarking, preferably in fiber modification and/or deinking (all claimed).    ADVANTAGE - The process provides a technically beneficial solution to problems encountered in pulp and paper industry processes; enables upgrading the economy of large-scale single-cell oil production; enables reducing the environmental burden; improves cost-efficiency of pulp and paper industry processes; reduces down-stream processing costs including water and enzyme stabilization; decreases transportation and packaging costs; decreases losses via direct transfer of enzymes to pulping process; decreases capital costs vs. dedicated (remote) facilities; utilizes the same raw material or raw material from same source for enzyme production and pulp/paper process results in direct induction and adaptation of enzymes to the raw material; and provides straight forward process control and output tuning and improvement opportunities directly within the biorefinery in enzyme production and pulp/paper process.    DETAILED DESCRIPTION - An integrated process (P1) for producing enzymes and lipids involves: a first process, which is a single cell oil production process, and a second process, which is a pulp and/or paper industry process, where organic material from pulp and/or paper industry is introduced into the single cell oil production process, and where in the single cell oil production process is used a microorganism capable of producing lipids or lipids and enzymes when cultivated on a medium comprising organic material from pulp and/or paper industry, producing lipids or lipids and enzymes by the microorganisms in the single cell oil production process and/or in a process connected into it, separating supernatant and microorganism cells from the microorganism culture, recovering lipids from the microorganism cells, and recovering the supernatant or a protein enriched fraction of the supernatant or a dilution of the supernatant comprising catalytically active enzymes from the single cell oil production process or from a process connected to it and optionally introducing it or them into the pulp and/or paper industry process. INDEPENDENT CLAIMS are included for the following:    (1) an enzyme preparation obtained by the process (P1);    (2) an integrated process system for lipid production and pulp and/or paper industry, comprising that a lipid production process uses organic material from pulp and/or paper industry as raw material for lipid production, and a pulp and/or paper process uses enzymes from supernatant from lipid production process;    (3) an integrated process system for lipid production and chemical pulping process, comprising the lipid production process uses hemicellulose, primary sludge and/or its fraction as raw material for lipid production, and pulp and/or paper process uses hemicellulases obtained from lipid production process;    (4) an integrated process system for lipid production and recycle fiber process comprising the lipid production process uses deinking sludge and/or its fractions as raw material for lipid production, and pulp and/or paper process uses enzymes obtained from lipid production process;    (5) an integrated process system for lipid production and mechanical pulping process, comprising the lipid production process uses residues from mechanical pulping, primary sludge and/or its fractions as raw material for lipid production, and pulp and/or paper process uses enzymes obtained from lipid production process; and    (6) process for producing lipids involving cultivating a microorganism capable of producing both lipids and enzymes under conditions suitable for lipid production and enzyme production on a medium comprising organic material from pulp and/or paper industry, and producing lipids and enzymes by the microorganism, separating the supernatant and microorganism cells from the microorganism culture, recovering lipids from the microorganism cells, and recovering the supernatant or a protein enriched fraction of the supernatant or a dilution of the supernatant comprising catalytically active enzymes.
