TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further involves processing the oil phase to obtain unsaturated fatty acids, algal meal, oil and glycerin; processing the glycerin to obtain 1,3 propanediol or 1,2 propanediol; and recycling the culture water back to the algal growing unit. The cultured algae and algal culture water contains secreted or unsecreted recombinant proteins or peptides, and the method further involves isolating the recombinant proteins or peptides. Preferred Components: The algae growing unit comprises sloping terraces (12) formed to drain into a central channel (16), where each terrace is supplied with culture water from a common culture water reservoir. The central channel communicates with the filtration unit and the method of supplying the harvested algae to filtration unit involves transporting the algae via the central channel. Preferred System: The facility further comprises a recombinant protein separation unit formed to produce recombinant proteins from the algal water phase and algal culture water. The algae growing unit is heated, at least in part, via solar energy. In the facility, the filtration unit is configured to recirculate the separated culture water back to the algae growing unit. The oil product processing unit is configured to purify a solvent and recirculate the purified solvent back to the solvent unit. In the facility, all energy is produced via renewable resources; and a saline aquifer is used as a culture water resource. The facility is located on marginal lands selected from arid desert lands and semiarid desert lands. Preferred Device: The filtration unit (u1) further comprises a washing apparatus formed to wash the sieve after the algal biomass has been removed from the harvesting chamber. The washing apparatus comprises at least one high pressure jet. In the unit (u1), the unit for forcing the culture water through the sieve comprises a vacuum pump; the unit for forcing the culture water through the sieve comprises a mechanical press; and the unit for removing the algal biomass from the harvesting chamber comprises a mechanical rotor formed to rotate the sieve.
