Where to find Botryococcus braunii?
Where to find Botryococcus braunii?
The colonial green microalga Botryococcus braunii is found in freshwater and brackish ponds and lakes around the world, where it often can be found in large floating masses.
Is Botryococcus braunii unicellular?
Botryococcus braunii are unicellular, planktonic, oval-shaped microalgae. The individuals live in a biofilm community that helps contribute to their external hydrocarbon production 3.
How do you grow Botryococcus braunii?
Optimal growth environment Botryococcus braunii has been shown to grow best at a temperature of 23 °C, a light intensity of 60 W/m2, with a light period of 12 hours per day, and a salinity of 0.15 molar NaCl. However, this was the results of testing with one strain, and others certainly vary to some degree.
Are all microalgae unicellular?
Microalgae are unicellular photosynthetic micro-organisms, living in saline or freshwater environments, that convert sunlight, water and carbon dioxide to algal biomass.
What is nannochloropsis sp?
Nannochloropsis spp. are microalgae living in freshwater and seawater that are related to diatoms and brown algae (Sukenik et al., 2009; Andersen et al., 1998). Nannochloropsis species have been used for several decades to produce nutraceuticals and feed supplements (Rodolfi et al., 2009).
What are some advantages and disadvantages of using algae for biofuel production?
Bio fuels derived from algae are viable sources of alternative energy. However, some disadvantages do exist. Algae fuels often have lower energy content than their petroleum counterparts, are more expensive, and produce less engine power and speed.
What is the difference between microalgae and macroalgae?
The key difference between macroalgae and microalgae is that macroalgae are large and multicellular aquatic photosynthetic plant-like organisms while microalgae are small and unicellular aquatic photosynthetic plant-like organisms. They are mostly aquatic and autotrophic in nature.
Is Nannochloropsis a diatom?
Is Nannochloropsis safe?
Nannochloropsis oculata is a marine-water single-celled algae of the Eustigmatophyceae class. Nannochloropsis sp. has been utilized as a food source in aquaculture, providing a source of omega-3 fatty acids [2]. Recently a N. oculata-derived oil has been determined safe for use in dietary supplements [3].
