The chief strategy for most algal biodiesel makers is to isolate the algal species that have a high oil content, that will also grow rapidly to make biodiesel, biocrude and drop-in fuels. Algae with high oil content such as Botryococcus braunii (Bb) grow gradually and can be harvested only limited times throughout a week, whereas algae with lesser oil content such as Dunaliella or Nannochloropsis (about 30% range) will develop more rapidly and can be harvested daily or even a few times a day. For this idea, most algal R&D designs and pre-commercial designs are utilizing algal strains with 30% oil content. Though by no means is 30% dry weight the maximum. 30% (naturally occurring) oil content will produce normally about 61,091 L of…show more content…
Neochloris oleabundans, Nannochloropsis oceeanica. and Spirulina Spp. proved to be suitable crude material for biodiesel manufacturing due to their high oil content (29.1%, 28.7% and 21.2% respectively). 50% more oil content was seen when all the three algae were grown in nitrogen deficit condition. Nannochloropsis oceanica is one of six species of the genus Nannochloropsis which has grabbed attention as a possible feedstock to produce biofuels due to its high productivity and oil content. Current progress in transformation and targeted gene replacement by homologous recombination in N. oceanica guarantee swift headway in the illumination of pathways of storage compound synthesis and their regulation. Given also its tiny genome, genetic engineering and ultimately synthetic biology tactics towards refining its productivity and adaptability have come within reach. In Nannochloropsis, a starch synthesis route is non-existent, leading to the accumulation of TAGs as a major result of photosynthetic carbon fixation (Vieler et al., 2012a). In addition, nuclear transformation and targeted gene substitution by homologous recombination have lately been reported for Nannochloropsis oceanica, which opens Nannochloropsis to molecular tactics for gene functional studies and engineering.
