N. oleoabundans a l Microalge: eukaryote Isolated from arid soil Saudi Arabia Chantanachat & Bold (1962). Oleaginoous (1970). Lipid content: 25% -??%. Triglycerides: gy main components from the lipid fraction Lipids are similar to those found in oleaginous plants Growth very well in water amended with salts, tolerates some salinity Is N. oleoabundas an adequate Microalge for biofuel production purposes

Remarks a l Proper biofuels are needed for airplanes Mexico is in an appropriate sun irradiation area Microalge have a high photosynthetic efficiency and can be used to attain biofuels N. oleoabundas is an adequate Microalge for biofuel production purposes p Produces up to 55 ton/ha/year using simple conditions: bubbling only air; water plus salts; do not need extreme-high irradiance; some degree of contamination is not an issue Potential had been evaluated at laboratory scale Metabolism can be easily switched limiting the culture with different nutrients A biorefinery can be develop from this culture It is necessary to obtain the mass and energy balances to generate an economic study, and to develop certificated test at different scales: Laboratory Pilot (greenhouse) Demonstration Scale Instituto de Biotecnología - UNAM 18
