Extracting oil from Algae:
There are few different ways to extract the oil from algae. The oil press is the simplest and most popular method. It can extract up to 75 percent of the oil from the algae being pressed. When Algaes are dried retain its oil content, which then can be "pressed" out with an oil press. because different strains of algae vary widely in their physical attributes, various press configurations work better for specific algae types.. For example, there could be screw, expeller, piston,etc. The hexane solvent method extracts up to 95 percent of oil from algae. First, the press squeezes out the oil. Then, leftover algae is mixed with hexane, then filtered and cleaned so will be no other chemical compound left in the oil. The supercritical fluids method extracts up to 100 percent of the oil from algae. Carbon dioxide acts as the supercritical fluid -- when a substance is pressurized and heated to There are many strains of algae, but all of them comprise the following: Proteins, Carbohydrates, lipids and Nucleic acids. While the percentage vary with the type of algae, there are algae types that are comprised up to 40% of their overall mss by fatty acid. It is this fatty acid that can be extracted and convert into biodiesel.In green algae, light is captured by light harvesting complex proteins, referred to as LHCI and LHCII. Their expression is dependent on environment conditions (light intensity). These proteins bind a large amount of the chlorophyll and carotenoids in the plant and play a role in both light capture and in the dissipation of excess energy, which would otherwise inhibit the photosynthetic reactions.
change its composition into a liquid as well as a gas. At this time,CO2 is mixed with the algae. When CO2 and algae are combined, the CO2 turns the algae completely into oil. But the additional equipment we need and work make this method a less popular option. Ultrasonic-assisted Extraction is a branch of sonochemistry, can greatly accelerate extraction processes. Using an ultrasonic reactor, ultrasonic waves are used to create cavitation bubbles in a solvent material, when these bubbles collapse near the cell walls, it creates shock waves and liquid jets that causes those cells walls to break and release their contents into the solvent. Which the lipid are released during that part.
