Algae can be converted into various types of fuels, depending on the production technologies and the part of the cells used. The lipid, or oily part of the algae biomass can be extracted and converted into biodiesel through a process similar to that used for any other vegetable oil, or converted in a refinery into "drop-in" replacements for petroleum-based fuels.
Specifically, algae bioreactors can be used to produce fuels such as biodiesel and bioethanol, to generate animal feed, or to reduce pollutants such as NO x and CO 2 in flue gases of power plants. Fundamentally, this kind of bioreactor is based on the photosynthetic reaction, which is performed by the chlorophyll -containing algae itself using ...
Algae also use chlorophyll, ... Oxygen is a waste product of light-dependent reactions, ... uses energy, but does not produce sugars.
So how does algae become biodiesel? Garton explained the algae has to be grown and cultivated. Afterwards, oil must be extracted from the algae, which can be further refined and turned into biodiesel.
[250] [251] In the shorter term, efforts are underway to commercialize algae-based fuels such as diesel, gasoline, and jet fuel. [71] [252] [253] Cyanobacteria have been also engineered to produce ethanol [254] and experiments have shown that when one or two CBB genes are being over expressed, the yield can be even higher. [255] [256]
Algae have photosynthetic machinery ultimately derived from cyanobacteria that produce oxygen as a byproduct of splitting water molecules, unlike other organisms that conduct anoxygenic photosynthesis such as purple and green sulfur bacteria. Fossilized filamentous algae from the Vindhya basin have been dated to 1.6 to 1.7 billion years ago. [11]
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
The biological hydrogen production with algae is a method of photobiological water splitting which is done in a closed photobioreactor based on the production of hydrogen as a solar fuel by algae. [ 13 ] [ 14 ] Algae produce hydrogen under certain conditions.
