Definitions

  • the invention relates to the field of microalgae and cyanobacteria, specifically how microalgae and cyanobacteria may be cultivated to produce biofuels, food for humans and animals, organic fertilizers or pharmaceutical products.
  • biofuels such as biodiesel and bioethanol. So far, these biofuels have been obtained from traditional oleaginous and cellulose rich feedstock. However, these traditional crops are not cost effective and the biofuel production yield is not high enough to compete with petroleum and its derivates. Therefore, the production of biofuels from traditional crops may lead to negative side effects such as intolerable rises in food prices and other global issues.
  • microalgae which are single cell photoautotrophic microorganisms.
  • Photoautotrophic organisms usually plants
  • photosynthesis to acquire energy from sunlight to convert carbon dioxide and water into organic materials to be used in cellular functions such as biosynthesis and respiration.
  • single cell microalgae living in an aqueous solution transform light into chemical energy much more efficiently than any other organism due to their greater access to carbon dioxide and dissolved minerals.
  • single cell microalgae are able to store lipids in higher density than any other plant or multi-celled organism which requires time, energy and nutrients to build support structures such as roots and stalks, light collector structures such as leaves, and lipid storing organs such as seeds. Therefore, to produce biofuels from microalgae presents the following advantages with respect conventional crops, if cultivated at a large scale:
  • Microalgae can grow in soils and tolerate water that is not useful for conventional agriculture. They can even tolerate the use of waste water and saltwater.
  • Microalgae are single cell organisms that convert sunlight into chemical energy through photosynthesis:
  • Microalgae and cyanobacteria are the planet's most abundant organisms, having adapted to extreme conditions such as polar and volcanic environments. They constitute the core of the trophic chain that sustains life on Earth as well as of the natural carbon cycle. They produce 80% of the planet's biomass (phytoplankton).
  • algae and cyanobacteria mass concentrations of lipids that may achieve proportions in the range of 60-70% by weight on a dry basis. Therefore, they are ideal to produce biodiesel.
  • algae constitute an effective and powerful carbon sink. It has been demonstrated that 100 tons of algae biomass will capture 170 tons of carbon dioxide.
  • microalgae growth In addition to light, carbon dioxide and water, photosynthesis requires inorganic salts which include essential elements such as nitrogen, phosphorous, iron and in some cases, silicon.
  • the optimal temperature for microalgae growth is between 20 and 30°C. Therefore, to cultivate microalgae and cyanobacteria, the following is required:
  • An aqueous media containing the algal culture which can be fresh water, brackish water or saltwater depending on the organism type.
  • Raceways or open ponds These systems are very simple. They are composed of a circulating pond or a set of circulating channels open to the atmosphere in which the aqueous solution circulates while capturing the sunlight.
  • the biggest advantage of these photobioreactors is that they are very economical.
  • open photobioreactors do not easily sustain the conditions for desired microalgae and cyanobacteria growth because the conditions of the algal culture can vary substantially over time due to water evaporation. In addition production is affected by contamination with unwanted algae and microorganisms that are deposited on the algal culture.
  • Closed photobioreactors have been developed in many different typologies to overcome the issues found in open ponds. Closed photobioreactors are based on closed hydraulic circuits, mostly tubular, through which the algal culture circulates. This type of system allows more intensive algae growth, requires less land surface and does not present contamination risks. However, with this technology, the oxygen produced during the photosynthesis, which is toxic to the algae and bacteria, may become an issue and might be hard to eliminate. Additionally, the cost of installation is around ten times higher than the cost of raceway photobioreactors. Due to the high costs, closed photobioreactors are not yet economically viable.
  • the illustrated embodiments of the invention respond to the specific need for mass, cost-effective microalgae and cyanobacteria biomass production.
  • the illustrated embodiments of the invention are based on a concept which offers the advantages of both raceway and closed tubular photobioreactors, namely the low costs of construction, operation and maintenance for the open raceway technology and the advantageous features of the closed photobioreactors (i.e. high production rates and biological safety).
  • the illustrated embodiments of the invention respond to the specific need for an economically viable mass production of biofuels.
  • embodiments of the invention include a closed photobioreactor which can operate in a continuous manner either in an outdoor or indoor environment.
  • one of the illustrated embodiments of the invention comprises a novel photobioreactor which comprises a hydraulic circuit through which the aqueous solution containing the culture with at least one type of photosynthetic organism circulates and gets exposed to the light source, a carbon dioxide feeding system, a zone to extract the oxygen from the aqueous solution, and a nutrient feeding system.

  • the present invention comprises a hydraulic circuit open to atmospheric pressure in which the algal/bacterial culture may be protected from external pollution since the photosynthesis reaction occurs within and along the transparent tubes.
  • the oxygen concentration of the aqueous solution increases as it passes through the tubes where photosynthesis takes place.
  • the length and diameter of the transparent or translucent tubes are calculated to predetermined levels in each application according to well understood design principles in order to avoid toxic oxygen concentrations. This generated oxygen is then eliminated in the next receiving or downstream channel.
  • the system is an open hydraulic system (i.e. at atmospheric pressure)
